Joint attention and symbolic play in young children with autism:
a randomized controlled intervention study.

Joint attention and symbolic play in young children with autism: a randomized
controlled intervention study. KasariC., FreemanS. & PaparellaT. (2006) Journal
of Child Psychology and Psychiatry (formerly Journal of Child Psychology and
Psychiatry and Allied Disciplines), 47, 611-620. Background Delays and deficits
in joint attention and symbolic play constitute two important developmental
problems in young children with autism. These areas of deficit have been well
studied in autism but have rarely been the focus of treatment efforts (see
Kasari, Freeman & Paparella 2001). In this study, we examine the efficacy of
targeted interventions of joint attention and symbolic play. Methods
Participants were 58 children with autism aged 3 and 4 years old (46 boys).
Children were randomized to a joint attention intervention, a symbolic play
intervention, or control group. Interventions were conducted 30 min daily for
5-6 weeks. Both structured assessments of joint attention and play skills and
mother-child interactions were collected pre and post intervention by
independent assessors. Results Results indicate that both intervention groups
improved significantly over the control group on certain behaviours. Children in
the joint attention intervention initiated significantly more showing and
responsiveness to joint attention on the structured joint attention assessment
and more child-initiated joint attention in the mother-child interaction. The
children in the play group showed more diverse types of symbolic play in
interaction with their mothers and higher play levels both on the play
assessment and in interaction with their mothers. Conclusions This randomized
controlled trial provides promising data on the specificity and generalizability
of joint attention and play interventions for young children with autism. Future
studies need to examine the long-term effects of these early interventions on
children's development.

Levetiracetam versus placebo in childhood and adolescent autism:
a double-blind placebo-controlled study.

The purpose of this study was to determine the safety and efficacy of the
anticonvulsant levetiracetam in the treatment of children with autism. A
previous open-label study in autistic children treated with levetiracetam
demonstrated effectiveness in hyperactivity, impulsivity/aggression, and mood
lability. Twenty patients with autism ranging from 5 to 17 years of age were
entered into a 10-week, placebo-controlled, double-blind trial of levetiracetam
versus placebo. The mean maximum dosage for levetiracetam was 862.50+/-279.19
mg/day. We evaluated global improvement of autism with the Clinical Global
Impression-Improvement (CGI-I) Scale and aggression and affective instability
with the Aberrant Behavior Checklist (ABC) parent and teacher ratings. We
measured repetitive behaviors using the Children's Yale-Brown
Obsessive-Compulsive Scale (CY-BOCS) score and impulsivity and hyperactivity
with the Conners' Rating Scale-Revised: Long Version for parent and teacher. No
significant difference was found between levetiracetam and placebo groups
comparing the change in CGI-I (t=0.350, d.f.=13.621, P=0.765), nor on change in
ABC, CY-BOCS or Conners' scales. These findings suggest that levetiracetam does
not improve behavioral disturbances of autism, but are limited by the small
sample size and lack of stratification of the autistic sample at baseline.

Risperidone Improves Behavioral Symptoms in Children with Autism
in a Randomized, Double-Blind, Placebo-Controlled Trial.
Pandina GJ, Bossie CA, Youssef E, Zhu Y, Dunbar F.
Medical Affairs, Janssen Pharmaceutica, Inc., Titusville, NJ, USA.
Subgroup analysis of children (5-12 years) with autism enrolled in an 8-week,
double-blind, placebo-controlled trial of risperidone for pervasive
developmental disorders. The primary efficacy measure was the Aberrant Behavior
Checklist-Irritability (ABC-I) subscale. Data were available for 55 children
given risperidone (n = 27) or placebo (n = 28); mean baseline ABC-I ( +/- SD)
was 20.6 (8.1) and 21.6 (10.2). Risperidone [mean dose ( +/- SD): 1.37 mg/day
(0.7)] resulted in significantly greater reduction from baseline to endpoint in
ABC-I versus placebo [mean change ( +/- SD): -13.4 (1.5) vs. -7.2 (1.4), P <
0.05; ES = -0.7]. The most common adverse effect with risperidone was somnolence
(74% vs. 7% with placebo). Risperidone treatment was well tolerated and
significantly improved behavioral problems associated with autism.

OBJECTIVE: To explore placebo-controlled efficacy and safety of atomoxetine (ATX)
for attention-deficit/hyperactivity disorder (ADHD) symptoms in children with
autism spectrum disorders (ASD). METHOD: Children ages 5 to 15 with ASD and
prominent ADHD symptoms were randomly assigned to order in a crossover of
clinically titrated ATX and placebo, 6 weeks each, separated by 1-week washout.
Slopes for each condition were compared by paired t test. RESULTS: In 2004-2005,
12 boys and 4 girls (7 with autistic disorder, 1 Asperger's, 8 pervasive
developmental disorder not otherwise specified) all completed at least 3 weeks
of each condition. On the primary outcome, the Hyperactivity subscale of the
Aberrant Behavior Checklist, ATX was superior to placebo (p =.043, effect size d
= 0.90). It was also superior on a 0 to 3 rating of nine DSM-IV ADHD
hyperactive/impulsive symptoms (p =.005, d = 1.27), but missed significance on
nine inattentive symptoms (p =.053, d= 0.89). Nine subjects responded to ATX,
four to placebo (25% improvement on the Hyperactivity subscale plus Clinical
Global Impressions-Improvement of 1-2. One was rehospitalized for recurrent
violence on ATX. Adverse events were otherwise tolerable, with no tendency to
stereotypy. CONCLUSIONS: ATX appears safe and effective for treating
hyperactivity in some children with autism spectrum disorders. The effect
appears as large as in a multisite methylphenidate trial in the same population,
with fewer intolerable side effects. Further study in autism spectrum disorders
is indicated.

Read my lips: The importance of the face in a computer-animated
tutor for vocabulary learning by children with autism.
Massaro DW, Bosseler A.
University of California,USA.
A computer-animated tutor, Baldi, has been successful in teaching vocabulary and
grammar to children with autism and those with hearing problems. The present
study assessed to what extent the face facilitated this learning process
relative to the voice alone. Baldi was implemented in a Language Wizard/Tutor,
which allows easy creation and presentation of a vocabulary lesson involving the
association of pictures and spoken words. The lesson plan included both the
receptive identification of pictures and the production of spoken words. A
within-subject design with five children with autism followed an alternating
treatment in which each child continuously learned to criterion sets of words
with and without the face. The rate of learning was significantly faster and the
retention was better with the face. The research indicates that at least some
children with autism benefit from the face in learning new language within an
automated program.

Teaching young children with autism to talk.
Yoder P, McDuffie A.
Department of Special Education, Vanderbilt University, Nashville, Tennessee

Frequent functional spoken communication is a common goal for young children
with autism. We propose that the number of different nonimitative, referential,
conventional, and communicative words used in a language sample is a reasonable
measure of the behavior we wish to increase in such children. We review our own
and others' studies focusing on young (i.e., 2 to 3 years old) children with
autism to provide a rationale for including object play and nonverbal
communication as potentially important treatment goals. Children who are not yet
fluent in object play and nonverbal communication may need to improve these
skills to facilitate the implementation and uptake of direct language therapy.
Past research has shown that object play, nonverbal communication, and useful
speech all are influenced by various types of interventions in young children
with autism.

Clinicians' perceptions of the benefits of aquatic therapy for
young children with autism: a preliminary study.
Vonder Hulls DS, Walker LK, Powell JM.
Hoquiam School District, Hoquiam, WA, USA.
OBJECTIVE: This purpose of this study was to identify clinicians' perceptions of
the benefits of aquatic therapy for young children with autism. METHODS:
Eighteen aquatic occupational therapists treating young children with autism
responded to a survey soliciting their opinions on changes in skill performance
resulting from aquatic therapy. RESULTS: A majority of clinicians reported a
substantial increase in swim skills, attention,muscle strength, balance,
tolerating touch, initiating/maintaining eye contact, and water safety.
CONCLUSION: The impairments, activity limitations, and participation
restrictions seen in children with autism can be wide-ranging and outcomes can
be difficult to operationally define and measure. In this preliminary study,
clinicians identified the areas they perceived as improving as a result of
aquatic therapy. This information could help narrow the field of likely outcomes
as a first step toward studies of the effectiveness of aquatic therapy for
children with autism.

Department of Child and Adolescent Neuropsychiatry (GPA, MRS, CK, MHF, MF),
Medical University of Vienna; Vienna, Austria; and ORYGEN Research Centre (GPA,
GEB), University of Melbourne, Melbourne, Australia.
BACKGROUND: There is increasing evidence that fatty acid deficiencies or
imbalances may contribute to childhood neurodevelopmental disorders. METHODS: We
conducted a randomized, double-blind, placebo-controlled 6-week pilot trial
investigating the effects of 1.5 g/d of omega-3 fatty acids (.84 g/d
eicosapentaenoic acid, .7 g/d docosahexaenoic acid) supplementation in 13
children (aged 5 to 17 years) with autistic disorders accompanied by severe
tantrums, aggression, or self-injurious behavior. The outcome measure was the
Aberrant Behavior Checklist (ABC) at 6 weeks. RESULTS: We observed an advantage
of omega-3 fatty acids compared with placebo for hyperactivity and stereotypy,
each with a large effect size. Repeated-measures ANOVA indicated a trend toward
superiority of omega-3 fatty acids over placebo for hyperactivity. No clinically
relevant adverse effects were elicited in either group. CONCLUSIONS: The results
of this study provide preliminary evidence that omega-3 fatty acids may be an
effective treatment for children with autism.

A randomized comparison of the effect of two prelinguistic
communication interventions on the acquisition of spoken communication in
preschoolers with ASD.
Yoder P, Stone WL.
Vanderbilt University, Nashville, TN 37203-5701, USA. paul.yoder@vanderbilt.edu
PURPOSE: This randomized group experiment compared the efficacy of 2
communication interventions (Responsive Education and Prelinguistic Milieu
Teaching [RPMT] and the Picture Exchange Communication System [PECS]) on spoken
communication in 36 preschoolers with autism spectrum disorders (ASD). METHOD:
Each treatment was delivered to children for a maximum total of 24 hr over a
6-month period. Spoken communication was assessed in a rigorous test of
generalization at pretreatment, posttreatment, and 6-month follow-up periods.
RESULTS: PECS was more successful than RPMT in increasing the number of
nonimitative spoken communication acts and the number of different nonimitative
words used at the posttreatment period. Considering growth over all 3
measurement periods, an exploratory analysis showed that growth rate of the
number of different nonimitative words was faster in the PECS group than in the
RPMT group for children who began treatment with relatively high object
exploration. In contrast, analogous slopes were steeper in the RPMT group than
in the PECS group for children who began treatment with relatively low object
exploration.

Long-term outcome of social skills intervention based on
interactive LEGO play.
Legoff DB, Sherman M.
Bancroft NeuroHealth, Haddonfield, NJ 08033, USA. dlegoff@aol.com
LEGO building materials have been adapted as a therapeutic modality for
increasing motivation to participate in social skills intervention, and
providing a medium through which children with social and communication
handicaps can effectively interact. A 3 year retrospective study of long-term
outcome for autistic spectrum children participating in LEGO therapy (N = 60)
compared Vineland Adaptive Behavior Scale socialization domain (VABS-SD) and
Gilliam Autism Rating Scale social interaction subscale (GARS-SI) scores preand
post-treatment with a matched comparison sample (N = 57) who received comparable
non-LEGO therapy. Although both groups made significant gains on the two outcome
measures, LEGO participants improved significantly more than the comparison
subjects. Diagnosis and pre-treatment full-scale IQ scores did not predict
outcome scores; however, Vineland adaptive behavior composite, Vineland
communication domain, and verbal IQ all predicted outcome on the VABS-SD,
especially for the LEGO therapy group. Results are discussed in terms of
implications for methods of social skills intervention for autistic spectrum
disorders.

The effect of a parent-implemented imitation intervention on
spontaneous imitation skills in young children with autism.
Ingersoll B, Gergans S.
Department of Psychology, Lewis & Clark College, 0615 SW Palatine Hill Rd.,
Portland, OR 97219, United States.
Children with autism exhibit significant deficits in their ability to
spontaneously imitate the play actions and descriptive gestures of others.
Reciprocal imitation training (RIT) is a naturalistic imitation intervention
designed to teach spontaneous imitation skills during play. This study assessed
the effectiveness of parent-implemented RIT using a multiple-baseline design
across three young children with autism and their mothers. After an initial
baseline, mothers were taught to implement RIT techniques with their child twice
a week for 10 weeks in a clinic setting. Two mothers were taught to use RIT to
teach object imitation. The third mother was taught to use RIT to target both
object and gesture imitation in a multiple-baseline design across behaviors.
Generalization was assessed in the families' homes at the end of treatment and a
1-month follow-up. Parents learned to use the intervention strategies and their
children exhibited increases in spontaneous imitation. These findings replicate
the results from previous studies, indicating that RIT is effective for teaching
imitation skills to young children with autism in a naturalistic setting and
extend the findings to parents.

Enhancing job-site training of supported workers with autism: a
reemphasis on simulation.
Lattimore LP, Parsons MB, Reid DH.
J. Iverson Riddle Developmental Center.
Currently recommended practice in supported work emphasizes training job skills
to workers with severe disabilities while on the job. Early behavioral research
indicated that skills needed in natural environments could also be trained in
simulated settings. We compared job-site plus simulation training for teaching
job skills to supported workers with autism to provision of training exclusively
on the job. Job-site training occurred in a small publishing company during the
regular work routine, and simulation training occurred in an adult education
site for people with severe disabilities. Two pairs of workers received training
on two job skills; one skill was trained at the job site and the other was
trained using job-site plus simulation training. Results indicated that for 3 of
the 4 comparisons, job-site plus simulation training resulted in a higher level
of skill or more rapid skill acquisition than did job-site-only training.
Results suggested that job-site training, the assumed best practice for teaching
vocational skills, is likely to be more effective if supplemented with
simulation training. Directions for future research include expanding
applications of behavioral technologies to other aspects of the current support
paradigm.

Risperidone: new indication. Behavioural disorders in children
with autism or mental disabilities: no progress.
[No authors listed]
(1) Sedative drugs are one option when autistic or mentally disabled children
have behavioural disorders that place them (or other people) in physical danger.
Among the classic neuroleptics, haloperidol is the drug with the best-documented
efficacy and safety. Placebo-controlled trials have also shown lithium to be
effective for this use. (2) Clinical evaluation of risperidone in children with
mental disabilities includes 3 placebo-controlled double-blind trials, 2 of
which involved 118 and 110 children aged from 5 to 12 years who were treated for
6 weeks. All 3 trials showed a partial behavioural improvement in about 75% of
children receiving risperidone, versus about 30% of children in the placebo
groups. (3) Clinical evaluation of risperidone in autistic children includes 2
placebo-controlled double-blind trials involving 110 and 79 children who were
treated for 8 weeks. One of these studies has been published in detail: 69% of
children partially improved with risperidone, versus 12% of the children on
placebo. (4) Given the absence of clinical trials comparing risperidone with
haloperidol or lithium, there is no evidence that risperidone is more effective
than these other treatments. (5) The principal adverse events observed in
short-term trials of risperidone were drowsiness (affecting about 50% of
children), weight gain (about 1.2 kg per month during the first months of
treatment), and hyperprolactinaemia (affecting about 12% of children).
Extrapyramidal disorders were infrequent during short-term trials, but their
incidence reached about 25% after a year of risperidone treatment. (6) The
impact of long-term risperidone therapy on growth and mental development is not
known. (7) In France treatment is about 7 times more expensive with risperidone
than with haloperidol. (8) In practice, the risk-benefit balance of risperidone
in the treatment of autistic or mentally disabled children with behavioural
disorders is no better overall than that of older products such as haloperidol
and lithium, which, in the absence of anything better, remain the standard
drugs.

OBJECTIVE: To evaluate the impact of risperidone on adaptive behavior in
children with autistic disorder who have serious behavior problems and to
examine different methods of scoring the Vineland Adaptive Behavior Scales to
measure change. METHOD: Forty-eight children (5 years to 16 years, 5 months) who
showed behavioral improvement during acute treatment with risperidone were
followed for 6 months and assessed with the Vineland Scales. RESULTS: Raw
scores, age-equivalents, and special norm percentile scores all showed
significant increases in adaptive behavior in the areas of communication, daily
living skills, and socialization (p <.01). During a period of 6 to 8 months,
children gained an average of 7.8 age-equivalent months in the area of
socialization, a > 6% improvement beyond what would be expected based on
baseline growth rates. CONCLUSIONS: Although limited by the absence of a control
group, these results suggest that risperidone may improve adaptive skills in
children with autistic disorder accompanied by serious behavioral problems.
Vineland age-equivalent scores appear to be most useful in assessing change with
treatment over time.

The Effect of Coloured Overlays on Reading Ability in Children
with Autism.
Ludlow AK, Wilkins AJ, Heaton P.
Department of Psychology, Goldsmiths College, University of London, New Cross,
London, UK.
Abnormalities of colour perception in children with autistic spectrum disorders
have been widely reported anecdotally. However, there is little empirical data
linking difficulties in colour perception with academic achievement. The Wilkins
Rate of Reading Test was administered with and without Intuitive Coloured
Overlays to 19 children with autistic spectrum disorders and to the same number
of controls individually matched for age and intelligence. Findings showed that
15 out of 19 (79%) children with autism showed an improvement of at least 5% in
reading speed when using a coloured overlay. In contrast only 3 of 19 (16%)
control group children showed such an improvement. The findings suggest that
coloured overlays may provide a useful support for reading for children with
autism.

Intervention for autistic spectrum disorders.
Filipek PA, Steinberg-Epstein R, Book TM.
Department of Pediatrics, University of California, Irvine, School of Medicine,
92868, USA. ForOCKids@uci.edu
A comprehensive approach to the assessment of any child with autism must be
matched specifically to each individual child and family. This premise holds for
medical therapies and special education services as well as psychopharmacologic
interventions. Behavioral, as opposed to pharmacologic, treatment is the
hallmark of effective intervention for autism. Physicians involved in the care
of children with autism need to become familiar with educational law and
intervention recommendations. Goals should include improved functional verbal
and nonverbal communication and social skills, increased engagement in
developmentally appropriate activities, improved fine and gross motor skills,
and the development of independent academic and organizations skills, as well as
replacement of problem behaviors with developmentally appropriate behaviors..
Medicating children with autism is difficult, but is often necessary for chronic
behavioral difficulties. In the absence of clear and present guidelines, we have
attempted to use evidence and clinical experience to suggest an algorithm based
on symptom clusters. Although children with autism may be responsive to
medications at lower doses and more susceptible to side effects than other
children, medical intervention can produce a significant improvement in the
quality of life for the child and family. Careful thought leading to correct
identification of target behaviors can appropriately direct better alternatives
for medication. Although these approaches are costly and time-consuming
endeavors, the expenditure of such efforts is the only available pathway to
improve the potential outcomes for individuals with autism as well as decrease
the lifetime societal costs for each individual.

Hyperbaric oxygen therapy may improve symptoms in autistic
children.
Rossignol DA, Rossignol LW.
Blue Ridge Medical Center, 4038 Thomas Nelson Highway, Arrington, VA 22922, USA;
University of Virginia, P.O. Box 800729, Charlottesville, VA, USA.
Autism is a neurodevelopmental disorder that currently affects as many as 1 out
of 166 children in the United States. Recent research has discovered that some
autistic individuals have decreased cerebral perfusion, evidence of
neuroinflammation, and increased markers of oxidative stress. Multiple
independent single photon emission computed tomography (SPECT) and positron
emission tomography (PET) research studies have revealed hypoperfusion to
several areas of the autistic brain, most notably the temporal regions and areas
specifically related to language comprehension and auditory processing. Several
studies show that diminished blood flow to these areas correlates with many of
the clinical features associated with autism including repetitive,
self-stimulatory and stereotypical behaviors, and impairments in communication,
sensory perception, and social interaction. Hyperbaric oxygen therapy (HBOT) has
been used with clinical success in several cerebral hypoperfusion syndromes
including cerebral palsy, fetal alcohol syndrome, closed head injury, and
stroke. HBOT can compensate for decreased blood flow by increasing the oxygen
content of plasma and body tissues and can even normalize oxygen levels in
ischemic tissue. In addition, animal studies have shown that HBOT has potent
anti-inflammatory effects and reduces oxidative stress. Furthermore, recent
evidence demonstrates that HBOT mobilizes stem cells from human bone marrow,
which may aid recovery in neurodegenerative diseases. Based upon these findings,
it is hypothesized that HBOT will improve symptoms in autistic individuals. A
retrospective case series is presented that supports this hypothesis.

The use of selective serotonin reuptake inhibitors in autism and
related disorders.
Posey DJ, Erickson CA, Stigler KA, McDougle CJ.
Department of Psychiatry, Indiana University School of Medicine, Indianapolis,
Indiana 46202, USA. dposey@iupui.edu
This paper reviews the published literature on the use of selective serotonin
reuptake inhibitors (SSRIs) for the treatment of symptoms associated with
autistic disorder and other pervasive developmental disorders (PDDs) in both
children and adults. To date, placebocontrolled studies of SSRIs have involved
only fluvoxamine (in children and adults) and fluoxetine (in children).
Open-label and retrospective studies of all other SSRIs in PDDs have also been
published that suggest effectiveness. Despite these positive reports, there
continues to be questions about the tolerability and appropriate dosing of SSRIs
in children with PDDs. Because of the limited number of placebo-controlled
studies, definitive conclusions about the role SSRIs should play in the clinical
treatment of children with PDDs cannot be drawn. Larger, placebo-controlled
studies of SSRIs are needed to guide clinical treatment.

Verbal communication outcomes in children with autism after
in-home father training.
Seung HK, Ashwell S, Elder JH, Valcante G.
Department of Communicative Disorders, College of Health Professions, University
of Florida, FL, USA.
Abstract Background This retrospective study examined the efficacy of in-home
father training on the communicative outcomes of children with autism. The
in-home training consisted of two components: (1) expectant waiting; and (2)
imitation with animation. Methods Efficacy of parent training was examined by
measuring the ratio of utterances produced by the parents to the utterances
produced by the children and the number of verbal imitation by the parents.
Outcomes of the children's verbal production were examined by measuring the
number of (1) single word utterances; (2) different words produced; and (3)
verbal response to questions. Results Following training there was a decrease in
the ratio of parent to child utterances and an increase in (1) the use of
imitation by the parents; and (2) the number of single words and different words
produced by the children. Discussion Results of this study suggested that the
parents had learned to wait for their children to communicate verbally during
communicative interactions and to interact more efficiently with their children
by using verbal imitation. Overall, the results of this study support the
efficacy of parent training that focuses on promotion of social reciprocity, and
have important implications for clinicians and future research.

An update on pharmacologic treatments for autism spectrum
disorders.
King BH, Bostic JQ.
Children's Hospital and Regional Medical Center, University of Washington,
Seattle, WA, USA.
Increasingly recognized over the past 20 years, autism spectrum disorders (ASD)
are heterogeneous. Medication treatments remain fundamentally ameliorative, so
prioritizing symptoms and matching medications to the patient's constellation of
symptoms remains the psychopharmacologic approach to ASD. Atypical antipsychotic
medications and glutamatergic agents are receiving increased attention, and
antidepressants are being examined for specific symptoms and for younger
patients who have autism. Large multisite networks (Research Units on Pediatric
Psychopharmacology; Studies to Advance Autism Research and Treatment) have been
constructed to expedite studies to elucidate effective treatments for ASD.
Findings from these networks are coupled with those from recent independent
trials.

Nicotinic cholinergic antagonists: A novel approach for the
treatment of autism.
Lippiello PM.
Preclinical Research, Targacept, Inc., 200 East First Street, Suite 300,
Winston-Salem, NC 27101, United States.
Evidence supports the hypothesis that normalization of cholinergic tone by
selective antagonism of neuronal nicotinic acetylcholine receptors (NNRs) may
ameliorate the core symptoms of autism. As often is the case, epidemiology has
provided the first important clues. It is well recognized that psychiatric
patients are significantly more often smokers than the general population. The
only known exceptions are obsessive-compulsive disorder (OCD), catatonic
schizophrenia and interestingly, autism. In this regard, clinical studies with
nicotine have demonstrated amelioration of symptoms of a number of diseases and
disorders, including Alzheimer's disease, Parkinson's disease, ADHD and
Tourette's syndrome. Nicotine's agonist properties at CNS NNRs have been
implicated in these effects and support the concept of self-medication as a
strong motivation for smoking in cognitively compromised individuals. On the
other hand, the inverse correlation between autism and smoking suggests that
smoking does not provide symptomatic relief and may actually be indicative of an
active avoidance of nicotine's agonist effects in this disorder. Neuroanatomical
evidence is consistent with this idea based on the presence of hypercholinergic
architecture in the autistic brain, particularly during the first few years of
development, making the avoidance of further stimulation of an already
hyperactive cholinergic system plausible. This may also explain why stimulants
(known to increase dopamine levels as do NNR agonists) appear to aggravate
autistic symptoms and why studies with cholinesterase inhibitors that increase
acetylcholine levels in the brain have yielded variable effects in autism. Taken
together, the evidence suggests the possibility that nicotinic cholinergic
antagonism may in fact be palliative. Pharmacological evidence supports this
hypothesis. For example, antidepressants, many of which are now known to be
non-competitive NNR antagonists, have been used successfully to treat a number
of autistic symptoms. More specifically, there is anecdotal evidence from at
least one medical practitioner that mecamylamine, a non-selective NNR
antagonist, is effective in treating many autistic symptoms, particularly those
that are refractory to most other treatments. Clearly there is a need for
carefully controlled clinical studies with novel selective NNR antagonists to
explore their potential as a new and exciting approach for the treatment of
autism.

Treatment planning for patients with autism spectrum disorders.
Aman MG.
>From The Nisonger Center, Ohio State University, Columbus, Ohio.
Patients with autism spectrum disorders (ASDs) can present with extremely
heterogeneous issues, and, therefore, their treatment can be very challenging.
Most patients with ASDs will benefit from contact with a multitude of
disciplines. In this article, treatment planning is structured in terms of the
patient's life stages. Early on, assessment of developmental milestones,
metabolic conditions, and hearing; making the diagnosis of ASD; and providing
genetic counseling are salient. As the child grows, speech and language therapy,
early intensive intervention, special education, parent training, and neurologic
assessment become important. With greater age, behavior therapy,
pharmacotherapy, occupational therapy, and sexuality issues are often in
ascendancy. As the patient approaches and proceeds through adulthood, transition
training, housing options, and guardianship issues may be priorities. Advocacy
is relevant throughout the life span. Professionals have an obligation to
familiarize parents with interventions likely to be fruitful or unhelpful. There
is growing evidence that early intensive behavior intervention, though
expensive, may produce lifelong gains in functioning. A variety of experimental
and/or unproven treatments are identified; mental health professionals can help
families with members who have ASDs by guiding them toward effective treatments
and away from therapies of unknown value but with potential risks and/or costs.

Safety issues with drug therapies for autism spectrum disorders.
McCracken JT.
>From the University of California, Los Angeles, Neuropsychiatric Institute, Los
Angeles.
Although currently no medication has been approved to treat autism spectrum
disorders, survey data show that community practitioners are prescribing a broad
range of medication treatments, including, but not limited to, antidepressants,
stimulants, antipsychotics, alpha agonists, and anticonvulsants. Patients with
autism spectrum disorders are also taking alternative treatments, including
herbal remedies, immunologic treatments, and vitamin therapies, which may
themselves produce side effects and/or create drug interactions with traditional
medications. Although short-term data on the efficacy and safety of commonly
prescribed treatments for autism spectrum disorders are increasing, few data are
currently available on long-term treatment for autism spectrum disorders, but
available studies and clinical experience can offer preliminary recommendations
on the safety of and monitoring needs for the medications currently used for
these disorders. Monitoring the safety and tolerability of drugs used in
patients with these disorders should minimize the burden of side effects and
optimize treatment outcome.

Treatment-emergent adverse events (AEs) were monitored during an 8-week,
double-blind, placebo-controlled trial of risperidone (0.5-3.5 mg/day) in 101
children and adolescents with a lifetime diagnosis of autistic disorder. In
addition, 37 placebo nonresponders received open-label risperidone for another 8
weeks. Of all the risperidone responders (n=65), 63 entered an open extension of
another 16 weeks (6 months total risperidone exposure), and 32 of them were
rerandomized to either continued risperidone therapy (n=16) or gradual
replacement with placebo (n=16) over 8 weeks. We collected the following
measures of safety and tolerability: (1) laboratory blood assessments (CBC with
differential, electrolytes, and liver function tests) and urinalyses, (2) vital
signs, (3) Side Effects Review of AEs thought to be associated with risperidone,
(4) sleep records, (5) Simpson Angus Neurological Rating Scale (SARS), (6)
Abnormal Involuntary Movement Scale (AIMS), and (7) height and weight. No
clinically significant changes were found on the lab tests. During the 8-week
acute trial, the most common AEs on the Side Effects Review, scored as moderate
or higher, were as follows (placebo and risperidone, respectively): Somnolence
(12% and 37%), enuresis (29% and 33%), excessive appetite (10% and 33%),
rhinitis (8% and 16%), difficulty waking (8% and 12%), and constipation (12% and
10%). "Difficulty falling asleep" and anxiety actually favored the risperidone
condition at statistically significant levels. The same AEs tended to recur
through 6 months of treatment, although often at reduced levels. Using Centers
for Disease Control (CDC) standardized scores, both weight and body mass index
(BMI) increased with risperidone during the acute trial (0.5 and 0.6 SDs,
respectively, for risperidone; 0.0 and 0.1 SDs, respectively, for placebo) and
into open-label extension (0.19 and 0.16 SDs, respectively), although the amount
of gain decelerated with time. Extrapyramidal symptoms, as assessed by the SARS,
were no more common for drug than placebo, although drooling was reported more
often in the risperidone group. There were no differences between groups on the
AIMS. Two subjects had seizures (one taking placebo), but these were considered
unrelated to active drug. Most AEs were mild to moderate and failed to interfere
with therapeutic changes; there were no unanticipated AEs. The side effects of
most concern were somnolence and weight gain.

Exploring a massage intervention for parents and their children
with autism: the implications for bonding and attachment.
Cullen-Powell LA, Barlow JH, Cushway D.
Interdisciplinary Research Centre in Health, Coventry University. l.powell@coventry.ac.uk
This exploratory study aimed to address two questions: (1) What does touch mean
between parents and their children with autism on completion of a massage
intervention? (2) Do parents feel that their relationship with their children
has changed on completion of a massage intervention? Fourteen parents agreed to
be interviewed. Data were collected before the massage intervention (baseline),
immediately after the massage intervention and 16 weeks from baseline and were
analysed using interpretative phenomenological analysis. At baseline, parents
felt distressed that they felt unable to get 'close' to their children. After
the intervention, parents reported feeling physically and emotionally closer to
their children. Children expressed a range of cues to initiate massage at home.
These benefits were maintained at follow-up for parents who continued to use
massage at home. In conclusion, giving massage to children with autism may help
to enhance the emotional bond between parent and child.

Complementary and alternative medicine in developmental
disabilities.
Brown KA, Patel DR.
Kalamazoo Center for Medical Studies, Michigan State University College of Human
Medicine, Kalamazoo, Michigan, USA.
Developmental disabilities (DD) are defined as a diverse group of severe chronic
conditions due to mental and/or physical impairments. Individuals with
developmental disabilities have difficulty with major life activities including
language, mobility, and learning. Developmental disabilities can begin anytime
during development--from prenatal up to 22 years of age, and the disability
usually lasts throughout a person's lifetime. Autism spectrum disorders,
cerebral palsy, mental retardation, and attention deficit hyperactivity disorder
are common conditions falling within the definition of developmental
disabilities. Complementary and alternative medicine (CAM) is becoming
increasingly utilized in the general population for treatment of everything from
the common cold to complex and chronic medical conditions. This article reviews
the prevalence of different types of CAM used for various developmental
disabilities.

Advances in drug treatments for children and adolescents with
autism and other pervasive developmental disorders.

Autism is a disorder characterised by abnormalities in language and social
development, and repetitive behaviours. Antipsychotics, including haloperidol
and risperidone, are the most widely studied drugs for reducing symptoms in
children and adolescents with autism. When administered at relatively low
dosages, antipsychotics have been shown to reduce repetitive behaviours (stereotypies)
and social withdrawal, as well as a number of related symptoms, such as
hyperactivity, aggression, self-abusive behaviour, temper tantrums, lability of
mood and irritability. Adverse effects of antipsychotics include sedation,
dizziness, increased appetite, weight gain, changes in the electrocardiogram
parameters, drooling, hyperprolactinemia and a risk of drug-related dyskinesias.
Other agents have been less well studied for the treatment of autism, but there
are suggestive data regarding their safety and efficacy. Of these agents, a
number have been investigated, based on theories about the aetiology of autism,
including SSRIs and naltrexone, although the efficacy of these agents has been
limited. Stimulant drugs have been shown to reduce hyperactivity and improve
focus, but they may cause behavioural worsening, weight loss and stereotypies de
novo. Secretin is a treatment that has received much media attention after
reports of efficacy from small open studies, but all controlled studies have
failed to show any benefit. In autism, alternative treatments have also been
used, but none have shown benefit in well-designed studies.

Long-Term Effects of Risperidone in Children With Autism Spectrum
Disorders: A Placebo Discontinuation Study.

and Dr. Scahill is with the Child Study Center, Yale University, New Haven, CT.
OBJECTIVE:: The short-term benefit of risperidone in ameliorating severe
disruptive behavior in pediatric patients with autism spectrum disorders is well
established; however, only one placebo-controlled, long-term study of efficacy
is available. METHOD:: Thirty-six children with an autism spectrum disorder
(5-17 years old) accompanied by severe tantrums, aggression, or self-injurious
behavior, started 8-week open-label treatment with risperidone. Responders (n =
26) continued treatment for another 16 weeks, followed by a double-blind
discontinuation (n = 24; two patients discontinued treatment because of weight
gain) consisting of either 3 weeks of taper and 5 weeks of placebo only or
continuing use of risperidone. Relapse was defined as a significant
deterioration of symptoms based on clinical judgment and a parent questionnaire.
RESULTS:: Risperidone was superior to placebo in preventing relapse: this
occurred in 3 of 12 patients continuing on risperidone versus 8 of 12 who
switched to placebo (p = .049). Weight gain, increased appetite, anxiety, and
fatigue were the most frequently reported side effects. CONCLUSIONS:: This study
indicates the effectiveness of risperidone during a period of several months,
reducing disruptive behavior in about half of the children with autism spectrum
disorders. The results provide a rationale for the continuing use of risperidone
beyond 6 months, although considerable weight gain can limit the use of this
agent.

Intensive behavioral treatment for children with autism:
four-year outcome and predictors.
Sallows GO, Graupner TD.
Wisconsin Early Autism Project (Madison).
Twenty-four children with autism were randomly assigned to a clinic-directed
group, replicating the parameters of the early intensive behavioral treatment
developed at UCLA, or to a parent-directed group that received intensive hours
but less supervision by equally well-trained supervisors. Outcome after 4 years
of treatment, including cognitive, language, adaptive, social, and academic
measures, was similar for both groups. After combining groups, we found that 48%
of all children showed rapid learning, achieved average posttreatment scores,
and at age 7, were succeeding in regular education classrooms. Treatment outcome
was best predicted by pretreatment imitation, language, and social
responsiveness. These results are consistent with those reported by Lovaas and
colleagues (Lovaas, 1987; McEachin, Smith, & Lovaas, 1993).

Combined vitamin B6-magnesium treatment in autism spectrum
disorder.
Nye C, Brice A, Nye C.
BACKGROUND: The use of mega-vitamin intervention began in the 1950s with the
treatment of schizophrenic patients. Pyroxidine (vitamin B6) was first used with
children diagnosed with "autism syndrome" when speech and language improvement
was observed in some children as a result of large doses of B6. A number of
studies attempted to assess the effects of vitamin B6-Magnesium (Mg) was found
to reduce undesirable side effects from B6) on characteristics such as verbal
communication, non-verbal communication, interpersonal skills, and physiological
function, in individuals with autism. OBJECTIVES: To determine the efficacy of
vitamin B6 and magnesium (B6-Mg) for treating social, communication, and
behavioural responses of children and adults with autism. SEARCH STRATEGY: We
searched the Cochrane Controlled Trials Register (Cochrane Library, Issue 2,
2002), MEDLINE (1966 to January 2002), EMBASE (1980 to January 2002), PsycINFO
(1887 to January 2002), Dissertation Abstracts International (1861 to January
2002). The search engine FirstSearch was also used (January 2002). All searches
were updated in April 2005. Reference lists for all the obtained studies and
other review articles were examined for additional studies. SELECTION CRITERIA:
All studies in which the participants had been diagnosed with autistic spectrum
disorder were randomly allocated prior to intervention and in which outcomes
were compared to either a placebo or non-treated group were included. DATA
COLLECTION AND ANALYSIS: Two reviewers independently evaluated and extracted
data from all potential studies identified for inclusion. MAIN RESULTS: This
update includes a new trial (Kuriyama 2002) to bring the total of included
studies to three (total n=33). One study, which used a cross-over design
(Tolbert 1993) provided insufficient data to conduct an analysis. Another
crossover study (Findling 1997) yielded no significant differences between
treatment and placebo group performances following the B6 intervention on
measures of social interaction, communication, compulsivity, impulsivity, or
hyperactivity. The latest study (Kuriyama 2002) was motivated by evidence from
epilepsy research and was focussed on a subgroup of children with pervasive
developmental disorders (PDDs) who exhibited clinical features similar to those
with pyroxidine-dependent epilepsy. This small study (n=8) only measured IQ and
'Social Quotient' and found a statistically significant benefit for IQ (5.2, 95%
CI = [0.2 to 10.3]) when in the treated group, by using change scores. AUTHORS'
CONCLUSIONS: Due to the small number of studies, the methodological quality of
studies, and small sample sizes, no recommendation can be advanced regarding the
use of B6-Mg as a treatment for autism.

Twelve children, all boys, aged 4 to 7 years, with a diagnosis of autistic
disorder and low concentrations of spinal
6R-l-erythro-5,6,7,8-tetrahydrobiopterin (tetrahydrobiopterin) were selected to
participate in a double-blind, randomized, placebo-controlled, crossover study.
The children received a daily dose of 3 mg tetrahydrobiopterin per kilogram
during 6 months alternating with placebo. Treatment-induced effects were
assessed with the Childhood Autism Rating Scale every third month. The results
showed small nonsignificant changes in the total scores of Childhood Autism
Rating Scale after 3- and 6-month treatment. Post hoc analysis looking at the 3
core symptoms of autism, that is, social interaction, communication, and
stereotyped behaviors, revealed a significant improvement of the social
interaction score after 6 months of active treatment. In addition, a high
positive correlation was found between response of the social interaction score
and IQ. The results indicate a possible effect of tetrahydrobiopterin treatment.

Institute, Royal Victoria Infirmary, Newcastle, United Kingdom. h.r.mcconachie@newcastle.ac.uk
OBJECTIVE: To evaluate a training course for parents, designed to help them
understand autism spectrum disorder and to facilitate social communication with
their young child. STUDY DESIGN: Controlled trial for 51 children aged 24 to 48
months, whose parents received either immediate intervention or delayed access
to the course. Outcome was measured 7 months after recruitment in parents' use
of facilitative strategies, stress, adaptation to the child; and in children's
vocabulary size, behavior problems, and social communication skills. RESULTS:
Taking into account scores at recruitment, child's level of ability, diagnostic
grouping, and the interval between assessments, a significant advantage was
found for the intervention group in parents' observed use of facilitative
strategies and in children's vocabulary size. CONCLUSIONS: The training course
is well received by parents and has a measurable effect on both parents' and
children's communication skills.

Children with autism present unique challenges related to communication,
behavior, and social skills. Each child with an autistic spectrum disorder (ASD)
exhibits individual characteristics of the disorder. Early identification of
autistic spectrum disorder has been shown to improve the child's benefit from
educational interventions. There may be health issues related to autism
including seizure disorders and dietary restrictions. Students with autism need
special consideration when they come to the health office for screening,
assessment of injuries, or administration of medication. Collaboration between
educators and school nurses is needed to develop and implement Individual
Education Plans and Individual Healthcare Plans. Community resources provide
valuable assistance to families of children with this challenging disorder.

Positive touch, the implications for parents and their children
with autism: an exploratory study.
Cullen LA, Barlow JH, Cushway D.
School of Health and Social Science, Interdisciplinary Research Centre in
Health, Coventry University, Priory Street, Coventry CV1 5FB, UK. l.powell@coventry.ac.uk
The aims of this study were (1) to explore the experience of touch between
parents and children with autism before, during, and after a Training and
Support Programme (TSP), and (2) to develop a model of the process of touch
therapy for this group of parents and children. Fourteen parents and their
children agreed to take part in the study. Five of these parents withdrew.
Reasons for withdrawal included personal circumstances and ill health. Data were
collected by semi-structured interviews with parents before attending the TSP
and Home Record Sheets completed by parents during the TSP. Results indicate
that before the TSP touch was experienced as out of parents' control. During the
TSP, the experience of touch appeared to change. A key benefit gained by parents
was the feeling of closeness to children. The key benefits gained by children
were perceived by the parents as improved sleep patterns, children were more
relaxed after receiving the massage and appeared more amenable to touch. Of
interest was children's request for massage at home. At 16-week follow-up both
parents and children continue to enjoy giving and receiving touch therapy,
respectively.

Placebo effects in developmental disabilities: implications for
research and practice.
Sandler A.
Department of Pediatrics, University of North Carolina at Chapel Hill, 28801,
USA. adsandler@POL.net
Recent clinical trials of secretin in children with autism showed robust placebo
effects and no benefit of secretin over placebo. This article explores the
reasons for the observed placebo effects, focusing on the heightening of
positive expectancy by media attention and by the sensory experiences associated
with intravenous injections. Comparisons are drawn with research involving other
novel treatments and other clinical populations of children with developmental
disabilities and neurobehavioral disorders. Research regarding mechanisms of
placebo effects is reviewed, including patient and clinician attributes,
expectancy effects, participation effects, changes in caregiver behavior, and
conditioning. New evidence regarding the biological basis of placebo effects is
briefly presented. Since placebo effects are ubiquitous and may operate by a
variety of mechanisms, research design is critical in designing clinical trials
and in evaluating other outcomes research. Measurement issues important for
research in developmental disabilities are emphasized. Ethical concerns have
been raised regarding the use of placebo in clinical research, but current
analysis suggests that placebo controls are necessary and defensible on ethical
grounds, if certain conditions are met. The study of placebo effects ("placebology")
holds great promise as a new area of research in therapeutics. The author's
research in the potential augmentation of stimulant effects in children with
attention deficit/hyperactivity disorder (ADHD) by adding placebo in open label
is briefly presented. The placebo has always been integral to the practice of
medicine, but advances in scientific medicine and medical ethics have diminished
the role and use of placebo in practice. An innovative approach to the ethical
use of placebo is proposed. Copyright 2005 Wiley-Liss, Inc.

Self injurious behavior in autism: clinical aspects and treatment
with risperidone.
Canitano R.
Division of Child Neuropsychiatry, University General Hospital of Siena, Italy.
Self injurious behavior (SIB) is frequent in autistic spectrum disorders. The
aim of this study was to investigate the phenomenology of SIB in a group of
children with autistic disorder, and to test whether treatment with risperidone
might reduce it. A group of eleven children diagnosed with autistic disorder
according to the DSM-IV criteria (mean age 8.7+/-2.2 ys) and with severe SIB
were recruited for an open study of six months of treatment with risperidone.
The Yale-Paris Self-Injurious Behavior Scale was used to delineate the clinical
characteristics and as an outcome measure. Head-hitting and hand biting were the
most frequent forms of self aggression observed. Nine children presented a mild
improvement in SIB and 2 did not show any variation. A decrease in Yale-Paris
Self Injurious Behavior Scale score (from M 15.1+/-1.4 to 13.3+/-1.4) was noted
mainly due to the reduction of frequency. Side effects of risperidone were not
severe.

Asperger syndrome in children.
Schnur J.
Purpose To review Asperger syndrome characteristics, assessment tools,
interventions, outcomes, and the role of the nurse practitioner in diagnosing
and caring for children with Asperger syndrome. Data sources Review of published
literature on and diagnostic criteria of the condition. Conclusions Asperger
syndrome is a pervasive developmental disorder or an autism spectrum disorder
that is thought to have an incidence higher than that of autism. Asperger
syndrome is different from autism, with a lack of delayed language as the most
distinct difference between Asperger syndrome and autism. Implications for
practice Because of the importance of early diagnosis of Asperger syndrome for
outcome improvement, screening at all well-child visits from infancy on is of
utmost importance to primary care pediatric nurse practitioners. With early
diagnosis, timely intervention is possible, which is proven to show improvement
in outcomes.

Autism spectrum disorders: emerging pharmacotherapy.
Bostic JQ, King BH.
Harvard Medical School, Boston, MA, USA.
Autism, Asperger and other pervasive developmental disorders (PDDs) are an
increasingly commonly identified group of conditions wherein patients experience
significant difficulty in social interactions, communicating with others, and
inflexible adherence to unusual, unhelpful and frequently stereotyped routines
and behaviour. These autism spectrum disorders are now being diagnosed earlier
in life (approximately 15 months), and often remain a chronic, daily burden for
those afflicted. In addition to the often profound impact on an individual's
quality of life, the familial, social and economic burdens of PDDs can be
enormous. No treatments are curative, and most pharmacological treatments are
employed to treat specific troubling symptoms rather than the core features of
the disorder itself. Therefore, more effective pharmacotherapies are desperately
needed. This review describes current and emerging pharmacotherapies that may
advance care of people with PDDs.

Stepping Stones Triple P: A pilot study to evaluate acceptability
of the program by parents of a child diagnosed with an Autism Spectrum Disorder.
Whittingham K, Sofronoff K, Sheffield JK.
School of Psychology, University of Queensland, Brisbane, Qld 4072, Australia.
The experience of parents of children with Autism Spectrum Disorder (ASD) in
standard parenting programs has not been researched, although anecdotal evidence
suggests that they do not find them acceptable. Forty-two parents of children
with ASD were asked to view a DVD explaining individual parenting strategies
from Stepping Stones, a new branch of the Triple P program targeted specifically
at parents of children with disabilities. Parents were asked to rate each
strategy for acceptability, usability and behavioural intention, i.e., their
intention to use the strategy. Additionally, parental attributions and parental
perceived control were explored as possible barriers to positive evaluations of
Stepping Stones parenting strategies. A focus group of parents was used to
gather more detailed parent response to the program. Parent responses to the
program were generally positive and attribution of the child's behaviour to
uncontrollable factors was found to predict higher ratings of usability. The
results were interpreted within the context of Weiner's attributional theory and
the theory of reasoned action. The limitations of this study and suggestions for
future research are discussed.

Intravenous secretin for autism spectrum disorder.
Williams K, Wray J, Wheeler D.
Clinical Epidemiology, The Children's Hospital at Westmead, Locked Bag 4001,
Westmead, NSW, AUSTRALIA, 2145.
BACKGROUND: Secretin is a gastro-intestinal hormone which has been presented as
an effective treatment for autism based on anecdotal evidence. OBJECTIVES: To
determine if intravenous secretin:1. improves the core features of autism
(social interaction, communication and behaviour problems); 2. improves the
non-core aspects of behaviour or function such as self injurious behaviour;3.
improves the quality of life of affected individuals and their carers; 4. has
short term and long term effects on outcome; 5. causes harm. SEARCH STRATEGY:
Results of electronic searches of CENTRAL, MEDLINE, EMBASE, PsycINFO, CINAHL,
ERIC, HealthStar and Sociofile (1998 - March 2005) were independently examined
by two authors. Reference lists of trials and reviews were searched; experts and
trialists were contacted to find unpublished studies. SELECTION CRITERIA:
Randomised controlled trials of intravenous secretin comparing secretin with a
placebo treatment in children or adults diagnosed with autism spectrum
disorders, where at least one standardised outcome measure was reported. DATA
COLLECTION AND ANALYSIS: Fourteen studies met inclusion criteria. All outcome
data were continuous. Where trials used cross-over designs, analysis was
conducted on results from first treatment phase, allowing combined analysis with
parallel design trials. Where standardised assessment tools generated scores as
outcome measures, comparisons were made between means of these scores. Where
baseline means were reported, differences between treatment and control were
determined to assess possible bias. Where mean change from baseline was
reported, this was used in preference to post-treatment scores for meta-analyses
or forest plots. As meta-analysis was possible for only one outcome (Childhood
Autism Rating Scale), it was impossible to use sensitivity or subgroup analyses
to assess impact of study quality, clinical differences in the intervention, or
clinically relevant differences between groups, such as age or presence of
gastrointestinal symptoms. MAIN RESULTS: Twenty-five established standardised
outcome measures were reported to assess core features of autism, communication,
behaviour, visio-spatial skills, affect and adverse events within fourteen
included studies. No more than four studies used any one outcome measure
similarly. Outcomes were reported between three and six weeks. RCTs of efficacy
of secretin in autism have not shown improvements for core features of autism.
AUTHORS' CONCLUSIONS: There is no evidence that single or multiple dose
intravenous secretin is effective and as such it should not currently be
recommended or administered as a treatment for autism. Further experimental
assessment of secretin's effectiveness for autism can only be justified if
methodological problems of existing research can be overcome.

OBJECTIVE: Risperidone has been found efficacious for decreasing severe
tantrums, aggression, and self-injurious behavior in children and adolescents
with autistic disorder (autism). The authors report on whether risperidone
improves the core symptoms of autism, social and communication impairment and
repetitive and stereotyped behavior. METHOD: The database from an 8-week
double-blind, placebo-controlled trial (N=101) and 16-week open-label
continuation study (N=63) of risperidone for children and adolescents with
autism was used to test for drug effects on secondary outcome measures: scores
on the Ritvo-Freeman Real Life Rating Scale, the Children's Yale-Brown Obsessive
Compulsive Scale, and the maladaptive behavior domain of the Vineland Adaptive
Behavior Scales. RESULTS: Compared to placebo, risperidone led to a
significantly greater reduction in the overall score on the Ritvo-Freeman Real
Life Rating Scale, as well as the scores on the subscales for sensory motor
behaviors (subscale I), affectual reactions (subscale III), and sensory
responses (subscale IV). No statistically significant difference was observed,
however, on the subscale for social relatedness (subscale II) or language
(subscale V). Risperidone also resulted in significantly greater reductions in
scores on the Children's Yale-Brown Obsessive Compulsive Scale and Vineland
maladaptive behavior domain. This pattern of treatment response was maintained
for 6 months. CONCLUSIONS: Risperidone led to significant improvements in the
restricted, repetitive, and stereotyped patterns of behavior, interests, and
activities of autistic children but did not significantly change their deficit
in social interaction and communication. Further research is necessary to
develop effective treatments for the core social and communicative impairments
of autism.

r.r.jordan@bham.ac.uk
There is a need to understand the difficulties faced by those with autistic
spectrum disorders (ASD) in educational settings if one is to manage and help
them manage their learning. This paper explores some of the most pertinent
problems that arise. It analyses perceptual, social, conceptual, emotional and
memorizing barriers to learning and shows how difficulties in communication are
exacerbated by educational language, which gives a poor model for those who have
no prior understanding of inter-personal communication. The notion of an
'autism-friendly' environment is examined as is the process of how schools and
other learning institutions might be helped to create such an environment.
Education as entitlement is distinguished from education as therapy and the
implications for inclusion are examined. It is argued that the best teaching
arises from an empathetic understanding and a willingness to be flexible, the
worst, from rigidity and an expectation that it is the child who must change.
There is no single approach that can meet all the needs of those with ASDs, but
nor are needs entirely determined by individual behaviour. It is the
understanding of ASD that enables the teacher to correctly identify the child's
learning needs and begin to meet them.

An analysis of music therapy program goals and outcomes for clients with
diagnoses on the autism spectrum.
Kaplan RS, Steele AL.
The Cleveland Music School Settlement.
The researchers analyzed data related to goals and outcomes over 2 program years
for 40 music therapy clients, ranging in age from 2-49 years, with diagnoses on
the autism spectrum. They investigated music therapy interventions, session
types, and formats most frequently used; goals most frequently addressed;
assessed level of difficulty of clients and their situations; and generalization
of skills attained in music therapy to other settings. The most common session
type was individual, followed by partner, small or large groups, peer model, or
a combination. Primary goal areas were ranked from language/communication (41%),
behavioral/psychosocial (39%), cognitive (8%), and musical (7%), to
perceptual/motor (5%). One hundred percent of subjects reached their initial
objectives in these goal areas within one year or less, regardless of session
type, level of difficulty, or goal area. Seventy-seven percent of intermediate
objectives were reached within that time. The most frequently utilized
interventions were interactive instrument playing, musical instrument
instruction, interactive singing, instrument choices, and song choices. Specific
interventions chosen did not affect accomplishment of initial objectives.
However, there was more variation among interventions in terms of achievement of
intermediate objectives. Session formats were ranked from activity-based as most
frequent to lesson-based, client-led/"shadow," and ensemble format. All formats
were successful when addressing initial objectives, with lesson-based format
being most effective in reaching intermediate objectives. Lastly, 100% of
parents and caregivers surveyed indicated subjects generalized skills/responses
acquired in music therapy to nonmusic therapy environments.

Language disorders and autism.

Early diagnosis of language disorders and autism is important, and early
intervention for autism and some language disorders makes a difference.
Developmental surveillance of children to detect these disorders should be a
routine part of medical practice. The persistence and pervasiveness of
communication and socialising deficits differentiate children with autism from
those with specific developmental language disorders. Hearing and vision
assessment is essential in any communication disorder. Interventions, targeted
to identified areas of need, should encompass communication enhancement,
behavioural therapy, educational modification, parent education and family
support. Pharmacological interventions have an important but discrete role in
autism, but there are no magic bullets. It is important to remember that the
normal childhood illnesses occur in children with developmental disorders.
Parents should be directed to reliable websites on the Internet, and given
information and books to read as well as phone numbers of relevant services (eg,
autism associations). There is a need for increased government financial support
for early intervention programs.

What is Known About Autism : Genes, Brain, and Behavior.
Santangelo SL, Tsatsanis K.
Psychiatric & Neurodevelopmental Genetics Unit, Center for Human Genetic
Research, Massachusetts General Hospital and Department of Psychiatry, Harvard
Medical School, Boston, Massachusetts, USADepartment of Epidemiology, Harvard
School of Public Health, Boston, Massachusetts, USA.
Autism is a neurodevelopmental disorder of genetic origins, with a heritability
of about 90%. Autistic disorder is classed within the broad domain of pervasive
developmental disorders (PDD) that also includes Rett syndrome, childhood
disintegrative disorder, Asperger syndrome, and PDD not otherwise specified (PDD-NOS).
Prevalence estimates suggest a rate of 0.1-0.2% for autism and 0.6% for the
range of PDD disorders. There is considerable phenotypic heterogeneity within
this class of disorders as well as continued debate regarding their clinical
boundaries. Autism is the prototypical PDD, and is characterized by impairments
in three core domains: social interaction, language development, and patterns of
behavior (restricted and stereotyped). Clinical pattern and severity of
impairment vary along these dimensions, and the level of cognitive functioning
of individuals with autism spans the entire range, from profound mental
retardation to superior intellect.There is no single biological or clinical
marker for autism, nor is it expected that a single gene is responsible for its
expression; as many as 15+ genes may be involved. However, environmental
influences are also important, as concordance in monozygotic twins is less than
100% and the phenotypic expression of the disorder varies widely, even within
monozygotic twins. Multiple susceptibility factors are being explored using
varied methodologies, including genome-wide linkage studies, and family- and
case-control candidate gene association studies. This paper reviews what is
currently known about the genetic and environmental risk factors,
neuropathology, and psychopharmacology of autism. Discussion of genetic factors
focuses on the findings from linkage and association studies, the results of
which have implicated the involvement of nearly every chromosome in the human
genome. However, the most consistently replicated linkage findings have been on
chromosome 7q, 2q, and 15q. The positive associations from candidate gene
studies are largely unreplicated, with the possible exceptions of the GABRB3 and
serotonin transporter genes.No single region of the brain or pathophysiological
mechanism has yet been identified as being associated with autism. Postmortem
findings, animal models, and neuroimaging studies have focused on the
cerebellum, frontal cortex, hippocampus, and especially the amygdala. The
cerebello-thalamo-cortical circuit may also be influential in autism. There is
evidence that overall brain size is increased in some individuals with
autism.Presently there are no drugs that produce major improvements in the core
social or pragmatic language deficits in autism, although several have limited
effects on associated behavioral features.The application of new techniques in
autism research is being proposed, including the investigation of abnormal
regulation of gene expression, proteomics, and the use of MRI and postmortem
analysis of the brain.

Autism -- experiences in a tertiary care hospital.
Kalra V, Seth R, Sapra S.
Department of Pediatrics, All India Institute of Medical Sciences, New Delhi,
India. Kalra_veena@hotmail.com
Pervasive developmental disorders (PDD) or Autistic Spectrum Disorders (ASD)
include Autistic Disorder (commonest), Asperger's syndrome, Childhood
Disintegrative Disorders, Rett's syndrome and PDD-NOS (not otherwise specified).
OBJECTIVE: Autism is an important cause of social disability and reported more
often from the developed world than from the developing countries. The present
study was aimed to establish the diagnosis of autism amongst children with
derangements of language, communication and behavior; ascertain and treat the
co-morbidities; identify underlying cause and create a sensitivity and awareness
among various health care professionals. METHODS: Sixty-two of the seventy-five
referred patients fulfilled the DSM-IV (Diagnostic and Statistical Manual of
Mental Disorder) criteria for autism. Evaluation included a detailed history,
clinical examination, IQ assessment, Connor's scoring for hyperactivity and
Fragile-X screening. Management of co-morbidities was done. A follow up of these
patients was done. Parents' assessment of the child was also done. A registry
for autistic children was established at the Department of Pediatrics with other
major institutions of Delhi. RESULTS : The male:female ratio was 8:1 and missed
diagnosis was common. Professional awareness is merited. Behavioral modification
by early intervention and stimulation improved the core symptoms of autism.
Important co-morbidities included mental retardation (95%), hyperactivity (53%)
and seizures (10%) cases. Control of co-morbidities in these children
facilitated child's periodic assessment and implementation of intervention
programmes. In the registry initiated 62 patients were enrolled at AIIMS and 6
were identified from other hospitals. CONCLUSION: Autism does occur in Indian
children too. Diagnosis is often missed. Capacity building among health
professionals by a more structured teaching of developmental disabilities in the
medical curriculum is required. The need to attend to co-morbidities and
associated symptoms was clear. The initiation of the registry and beginning of
networking was important.

What distinguishes autism spectrum disorders from other developmental disorders
before the age of four years?

The increasing recognition of the benefits of early intervention for children
with autism spectrum disorder (ASD) stresses the importance of early
identification of children who might benefit from those programs. However, in
the early years of life it may be difficult to distinguish children with ASD
from children with other developmental disorders. The aim of the present study
was to identify behavioural patterns that could facilitate this differentiation.
Prior to diagnostic assessment, 2- and 3-year-old children (n=30), all referred
to a clinic for "possible autism", were observed in a semi-structured play
interaction, and their parents were interviewed about the children's early
development from 0 to 24 months. Following diagnostic assessment, the 17
children fulfilling the ICD-10 criteria for ASD were compared to the 13 children
diagnosed with other developmental disorders (outside the autism spectrum). On
the basis of parent reports only a few distinguishing signs of ASD were found
before 24 months of age. On the basis of professional observations in a
semi-structured play interaction several distinguishing signs were found for the
2- and 3-year-olds; smiles in response, responds to name, follows pointing,
looks to "read" faces, initiates requesting verbal and nonverbal behaviours, and
functional play.

Autistic disorder and viral infections.
Libbey JE, Sweeten TL, McMahon WM, Fujinami RS.
Department of Neurology, University of Utah, Salt Lake City, Utah 84132-2305,
USA.
Autistic disorder (autism) is a behaviorally defined developmental disorder with
a wide range of behaviors. Although the etiology of autism is unknown, data
suggest that autism results from multiple etiologies with both genetic and
environmental contributions, which may explain the spectrum of behaviors seen in
this disorder. One proposed etiology for autism is viral infection very early in
development. The mechanism, by which viral infection may lead to autism, be it
through direct infection of the central nervous system (CNS), through infection
elsewhere in the body acting as a trigger for disease in the CNS, through
alteration of the immune response of the mother or offspring, or through a
combination of these, is not yet known. Animal models in which early viral
infection results in behavioral changes later in life include the influenza
virus model in pregnant mice and the Borna disease virus model in newborn Lewis
rats. Many studies over the years have presented evidence both for and against
the association of autism with various viral infections. The best association to
date has been made between congenital rubella and autism; however, members of
the herpes virus family may also have a role in autism. Recently, controversy
has arisen as to the involvement of measles virus and/or the measles, mumps,
rubella (MMR) vaccine in the development of autism. Biological assays lend
support to the association between measles virus or MMR and autism whereas
epidemiologic studies show no association between MMR and autism. Further
research is needed to clarify both the mechanisms whereby viral infection early
in development may lead to autism and the possible involvement of the MMR
vaccine in the development of autism.

reported an uncontrolled trial of secretin with three participants with autism,
which apparently resulted in significant behavioral improvement. Subsequently,
secretin was widely used. Sandler et al. [Sandler, A. D., Sutton, K. A., SeWeese,

reported the first double-blind trial of secretin with negative results. This
article is a review of 15 double-blind trials of secretin. Almost none of the
studies reported any significant effects and none concluded that secretin was
effective. Transient effects of secretin, including both minor benefits and
behavioral deterioration were reported, probably due to multiple statistical
tests. Four papers reported data on differential responding in sub-groups of
participants, including those with gastrointestinal symptoms. These effects were
not replicable. At this time there is no robust evidence that secretin is an
effective treatment for pervasive developmental disorders.

Pilot study of a moderate dose multivitamin/mineral supplement
for children with autistic spectrum disorder.
Adams JB, Holloway C.
Arizona State University, Tempe, AZ.
Objective: Determine the effect of a moderate dose multivitamin/mineral
supplement on children with autistic spectrum disorder. Design: Randomized,
double-blind, placebo-controlled 3-month study. Subjects: Twenty (20) children
with autistic spectrum disorder, ages 3-8 years. Results: A Global Impressions
parental questionnaire found that the supplement group reported statistically
significant improvements in sleep and gastrointestinal problems compared to the
placebo group. An evaluation of vitamin B(6) levels prior to the study found
that the autistic children had substantially elevated levels of B6 compared to a
control group of typical children (75% higher, p < 0.0000001). Vitamin C levels
were measured at the end of the study, and the placebo group had levels that
were significantly below average for typical children, whereas the supplement
group had near-average levels. Discussion: The finding of high vitamin B(6)
levels is consistent with recent reports of low levels of pyridoxal-5-phosphate
and low activity of pyridoxal kinase (i.e., pyridoxal is only poorly converted
to pyridoxal- 5-phosphate, the enzymatically active form). This may explain the
functional need for high-dose vitamin B(6) supplementation in many children and
adults with autism.

Repetitive behaviors are a core symptom domain in autism that has been linked to
alterations in the serotonin system. While the selective serotonin-receptive
inhibitor fluvoxamine has been shown to be effective in adults with autism, as
yet no published placebo controlled trials with these agents document safety and
efficacy in children with autism. This study examines the selective serotonin
reuptake inhibitor liquid fluoxetine in the treatment of repetitive behaviors in
childhood and adolescent autism spectrum disorders (ASDs). In total, 45 child or
adolescent patients with ASD were randomized into two acute 8-week phases in a
double-blind placebo-controlled crossover study of liquid fluoxetine. Study
design included two randomized 8-week fluoxetine and placebo phases separated by
a 4-week washout phase. Outcome measures included measures of repetitive
behaviors and global improvement. Low-dose liquid fluoxetine (mean final dose:
9.9+/-4.35 mg/day) was superior to placebo in the treatment of repetitive
behaviors by CY-BOCS compulsion scale. The effect size was in the moderate to
large range, and the doses used were low. Liquid fluoxetine was only slightly,
and not significantly, superior to placebo on CGI autism score partially due to
a phase order effect. However, fluoxetine was marginally superior to placebo on
a composite measure of global effectiveness. Liquid fluoxetine did not
significantly differ from placebo on treatment emergent side effects. Liquid
fluoxetine in low doses is more effective than placebo in the treatment of
repetitive behaviors in childhood autism. Limitations include small sample size
and the crossover design of the study. Further replication and long-term
maintenance trials are needed.Neuropsychopharmacology advance online

A retrospective assessment of topiramate in children and
adolescents with pervasive developmental disorders.

of Pittsburgh School of Medicine, Pittsburgh, PA 15213, USA. hardanay@msx.upmc.edu
An open-label retrospective study was conducted to assess the effectiveness and
tolerability of topiramate in children and adolescents with pervasive
developmental disorders (PDD). Topiramate is a novel antiepileptic drug approved
as an adjunctive treatment for seizure disorders. A retrospective chart review
was conducted in an outpatient clinic specialized in treating individuals with
developmental disabilities, to identify all children and adolescents with PDD
who received topiramate. Patients were included if concomitant medications
remained unchanged. Treatment response was assessed using the Global Improvement
item of the Clinical Global Impressions scale (CGI-GI), based on a review of
medical records and the Conners Parent Scale (CPS), as completed by parents.
Fifteen patients were identified (12 male, 3 female; age = 14.7 +/- 3.3 years),
including 11 patients with autistic disorder, 2 patients with Asperger's
disorder, and 2 patients with PDD not otherwise specified (PDD, NOS). Eight
patients (4 patients with autistic disorder, 2 patients with Asperger's
disorder, and 2 patients with PDD, NOS) were judged to be responders, as defined
by a score of 1 or 2 on the CGI-GI. Treatment duration was 25 +/- 16 weeks, and
the mean dose was 235 +/- 88 mg. Differences between baseline and the
end-of-trial period were observed in the following CPS subscales: conduct,
hyperactivity, and inattention. No differences were noted in the psychosomatic,
learning, and anxiety subscales. Three patients discontinued topiramate because
of side effects, with 2 patients experiencing cognitive difficulties and 1
patient a skin rash. Topiramate may be beneficial for treating secondary
symptoms of PDD, and prospective openlabel studies and double-blind,
placebo-controlled studies to assess its efficacy and safety are needed.

Self-injurious behavior and the efficacy of naltrexone treatment:
a quantitative synthesis.

Department of Educational Psychology, University of Minnesota, Minneapolis,
Minnesota 55455, USA. symon007@umn.edu
People with mental retardation, autism, and related developmental disabilities
who self-injure are treated with a wide array of behavioral techniques and
psychotropic medications. Despite numerous reports documenting short-term and
some long-term changes in self-injury associated with the opiate antagonist
naltrexone hydrochloride, no quantitative review of its efficacy has been
reported. We conducted a quantitative synthesis of the peer-reviewed published
literature from 1983 to 2003 documenting the use of naltrexone for the treatment
of self-injurious behavior (SIB). Individual-level results were analyzed given
subject and study characteristics. A sample of 27 research articles involving 86
subjects with self-injury was reviewed. Eighty percent of subjects were reported
to improve relative to baseline (i.e., SIB reduced) during naltrexone
administration and 47% of subjects SIB was reduced by 50% or greater. In studies
reporting dose levels in milligrams, males were more likely than females to
respond. No significant relations were found between treatment outcomes and
autism status or form of self-injury. Results are discussed with respect to
future efficacy work related to study outcomes and the pharmacological treatment
of self-injury. (c) 2004 Wiley-Liss, Inc.

Diagnosing and treating comorbid (complicated) bipolar disorder.
McElroy SL.
Department of Psychiatry, University of Cincinnati College of Medicine, OH
45267, USA. susan.mcelroy@uc.edu
Comorbidity is the rule, not the exception, in bipolar disorder. The most common
mental disorders that co-occur with bipolar disorder in community studies
include anxiety, substance use, and conduct disorders. Disorders of eating,
sexual behavior, attention-deficit/hyperactivity, and impulse control, as well
as autism spectrum disorders and Tourette's disorder, co-occur with bipolar
disorder in clinical samples. The most common general medical comorbidities are
migraine, thyroid illness, obesity, type II diabetes, and cardiovascular
disease. Bipolarity is a marker for comorbidity, and comorbid disorders,
especially multiple conditions occurring when a patient is young, may be a
marker for bipolarity. Relatively few controlled clinical studies have examined
the treatment of bipolar disorder in the context of comorbid conditions (i.e.,
complicated or comorbid bipolar disorder). However, the first step in treating
any type of complicated bipolar disorder--stabilizing a patient's mood--may be
associated with improving the comorbid disorder. Standard mood stabilizers,
atypical antipsychotics, and non-antimanic antiepileptic agents are emerging as
potentially useful treatments for several of the disorders that frequently
co-occur with bipolar disorder, and therefore may be useful treatments for
comorbid bipolar disorder.

Management of hyperactivity and other acting-out problems in
patients with autism spectrum disorder.
Aman MG.
Nisonger Center, Ohio State University, Columbus, OH 43210-1296, USA.
Hyperactivity/impulsivity, aggression, self injury, and irritability are
disruptive behaviors that frequently accompany autism spectrum disorders (ASD).
The psychostimulants and atypical antipsychotics have been used with some
success to manage hyperactivity, but neither drug group is fully satisfactory
and clinical response to the stimulants varies. For other disruptive symptoms
(irritability, aggression, self injury), both older antipsychotics and newer
atypical antipsychotics have been shown to have helpful effects. Because of
potential side effects, atypical antipsychotics should ordinarily be preferred
over older agents. A small group of studies suggests that selective serotonin
reuptake inhibitors may be helpful in managing symptoms related to aggression,
self injury, and the like. A small and largely imperfect literature suggests
that beta blockers, mood stabilizers, and alpha-2 agonists may also have some
role for treating such symptoms. More research is needed on the management of
all of these target symptoms, both for new agents (e.g., atomoxetine) and for
established psychoactive medicines.

OBJECTIVE: To investigate the efficacy and safety of risperidone for the
treatment of disruptive behavioral symptoms in children with autism and other
pervasive developmental disorders (PDD). METHODS: In this 8-week, randomized,
double-blind, placebo-controlled trial, risperidone/placebo solution (0.01-0.06
mg/kg/day) was administered to 79 children who were aged 5 to 12 years and had
PDD. Behavioral symptoms were assessed using the Aberrant Behavior Checklist
(ABC), Nisonger Child Behavior Rating Form, and Clinical Global
Impression-Change. Safety assessments included vital signs, electrocardiogram,
extrapyramidal symptoms, adverse events, and laboratory tests. RESULTS: Subjects
who were taking risperidone (mean dosage: 0.04 mg/kg/day; 1.17 mg/day)
experienced a significantly greater mean decrease on the irritability subscale
of the ABC (primary endpoint) compared with those who were taking placebo. By
study endpoint, risperidone-treated subjects exhibited a 64% improvement over
baseline in the irritability score almost double that of placebo-treated
subjects (31%). Risperidone-treated subjects also exhibited significantly
greater decreases on the other 4 subscales of the ABC; on the conduct problem,
insecure/anxious, hyperactive, and overly sensitive subscales of the Nisonger
Child Behavior Rating Form (parent version); and on the Visual Analog Scale of
the most troublesome symptom. More risperidone-treated subjects (87%) showed
global improvement in their condition compared with the placebo group (40%).
Somnolence, the most frequently reported adverse event, was noted in 72.5%
versus 7.7% of subjects (risperidone vs placebo) and seemed manageable with
dose/dose-schedule modification. Risperidone-treated subjects experienced
statistically significantly greater increases in weight (2.7 vs 1.0 kg), pulse
rate, and systolic blood pressure. Extrapyramidal symptoms scores were
comparable between groups. CONCLUSIONS: Risperidone was well tolerated and
efficacious in treating behavioral symptoms associated with PDD in children.

A new social communication intervention for children with autism:
pilot randomised controlled treatment study suggesting effectiveness.
Aldred C, Green J, Adams C.
Human Communication and Deafness Group, University of Manchester, UK.
BACKGROUND: Psychosocial treatments are the mainstay of management of autism in
the UK but there is a notable lack of a systematic evidence base for their
effectiveness. Randomised controlled trial (RCT) studies in this area have been
rare but are essential because of the developmental heterogeneity of the
disorder. We aimed to test a new theoretically based social communication
intervention targeting parental communication in a randomised design against
routine care alone. METHODS: The intervention was given in addition to existing
care and involved regular monthly therapist contact for 6 months with a further
6 months of 2-monthly consolidation sessions. It aimed to educate parents and
train them in adapted communication tailored to their child's individual
competencies. Twenty-eight children with autism were randomised between this
treatment and routine care alone, stratified for age and baseline severity.
Outcome was measured at 12 months from commencement of intervention, using
standardised instruments. RESULTS: All cases studied met full Autism Diagnostic
Interview (ADI) criteria for classical autism. Treatment and controls had
similar routine care during the study period and there were no study dropouts
after treatment had started. The active treatment group showed significant
improvement compared with controls on the primary outcome measure--Autism
Diagnostic Observation Schedule (ADOS) total score, particularly in reciprocal
social interaction--and on secondary measures of expressive language,
communicative initiation and parent-child interaction. Suggestive but
non-significant results were found in Vineland Adaptive Behaviour Scales
(Communication Sub-domain) and ADOS stereotyped and restricted behaviour domain.
CONCLUSIONS: A Randomised Treatment Trial design of this kind in classical
autism is feasible and acceptable to patients. This pilot study suggests
significant additional treatment benefits following a targeted (but relatively
non-intensive) dyadic social communication treatment, when compared with routine
care. The study needs replication on larger and independent samples. It should
encourage further RCT designs in this area.

AEDs and psychotropic drugs in children with autism and epilepsy.
Tuchman R.
Department of Neurology, Dan Marino Center, Miami Children's Hospital,
University of Miami, Miami, Florida, USA. tuchman@att.net
The efficacy of antiepileptic drugs (AEDs) and psychotropic medications in
children with autism is limited to the treatment of seizures or to specific
behaviors such as irritability, impulsivity, hyperactivity, repetitive
behaviors, or aggression. The reliability and value of the available data--to
determine the efficacy of these medications in autism--are limited by lack of
controlled clinical trials, the small number of subjects, the heterogeneity of
the population studied, and the brief duration of most drug trials. Indeed, few
controlled clinical trials using AEDs in autism, with or without seizures, have
been conducted. Because some AEDs also have a positive effect on mood, the
benefits that children with autism sometimes obtain from these medications may
not be due to the treatment of the abnormal electrical activity or the seizures
per se but to an effect on common neuronal systems responsible for both behavior
and epilepsy. The relationship between epilepsy and autism, and specifically the
effects that abnormal electrical activity may have on the developing brain, may
provide some valuable insights into the type of studies that are needed to help
us understand the pathophysiology of autism.

Comparison of behavioural and natural play interventions for
young children with autism.
Bernard-Opitz V, Ing S, Kong TY.
National University of Singapore, Singapore. verabernard@cox.net
The article reports the results of a pilot study comparing traditional
behavioural approaches and natural play interventions for young children with
autism over a 10 week period. Two matched groups of eight young children with
autism participated. Using a crossover design, children in both groups showed
positive gains in compliance, attending, play and communication with their
therapists and parents. Improvements in attending and compliance were higher
following the behavioural condition compared with the natural play condition.
Seven participants had reduced autism scores after the intervention. The
findings suggest that behavioural and play approaches affect behaviour in
different ways and that autistic symptomatology of young children may be
amenable to treatment. The discussion focuses on the active ingredients of
treatments and the need to base efficacy research on well-planned treatment
comparisons.

Sleep problems in children with autism.
Gail Williams P, Sears LL, Allard A.
Weisskopf Center for the Evaluation of Children, University of Louisville,
Louisville, KY 40202, USA. pgwill@iegwise.louisville.edu
Autism is a developmental disability characterized by severe deficits in social
interaction and communication, and the presence of repetitive-ritualistic
behaviors. Sleep problems are frequently reported by parents of children with
autism with prevalence estimates of 44-83% for sleep disorders in this
population. To better understand sleep in autism, we surveyed sleep problems in
210 children with autism using a Likert-based questionnaire for parent report.
The most frequently reported sleep problems included difficulty in falling
asleep, restless sleep, not falling asleep in own bed, and frequent wakenings.
Least frequently reported sleep problems were sleep walking, morning headaches,
crying during sleep, apnea, and nightmares. When surveys were divided into
mental retardation (MR)/not MR categories, no significant differences were
identified in frequencies of reported sleep problems except for waking at night
which occurred much more frequently in the MR group. There was also no
difference in sleep problems related to age of the child other than nocturnal
enuresis. An association was noted between certain medical problems and sleep
problems. Vision problems, upper respiratory problems, and runny nose were
associated with decreased nighttime sleep. Vision problems, poor appetite, and
poor growth were associated with increased nighttime waking. Poor appetite and
poor growth were associated with decreased willingness to fall asleep. This
study confirms a high prevalence of sleep problems reported by parents of
children with autism and points to the need for more systematic research as an
initial step in developing treatment strategies.

TN 38163-0001, USA. mmoore31@utmem.edu
OBJECTIVE: To review literature describing use of selective serotonin-reuptake
inhibitors (SSRIs) in the management of functional impairments associated with
autistic disorder. DATA SOURCES: EMBASE (1980-3rd quarter of 2003),
International Pharmaceutical Abstracts (1970-August 2003), and MEDLINE
(1966-August 2003) were searched. Search terms included autism, autistic
disorder, citalopram, fluoxetine, fluvoxamine, paroxetine, selective
serotonin-reuptake inhibitors, and sertraline. DATA SYNTHESIS: Studies and case
reports evaluating treatment outcomes associated with the use of SSRIs in
managing impairments of autism were reviewed. Multiple SSRI dosing ranges were
evaluated in autistic patients of different ages with various functional
impairments. No specific SSRI or dose range has been shown to improve a specific
autistic symptom although some patients have demonstrated improvements.
CONCLUSIONS: Benefits with SSRIs in treating functional impairments in autism
have been observed. Response to therapy and adverse effects are individualized.
Current evidence does not support selection of one SSRI over another for any
impairment associated with autism.

Effects of speech and print feedback on spelling by children with
autism.
Schlosser RW, Blischak DM.
Department of Speech-Language Pathology & Audiology, Northeastern University,
Boston, MA 02115, USA. r.schlosser@neu.edu
In this systematic replication of a previous study (R. W. Schlosser, D. M.
Blischak, P. J. Belfiore, C. Bartley, and N. Barnett, 1998), the effects of
speech and print feedback on spelling performance were evaluated. Four children
with autism and no functional speech were taught to spell words with a
speech-generating device under 3 feedback conditions. In the auditory-visual
condition, children received both speech and print feedback, whereas in the
auditory and visual conditions, only 1 type of feedback was provided. An adapted
alternating treatments design was used. All 4 children reached criterion across
conditions. Although 3 children reached criterion first with print or
speech-print feedback, 1 child was most efficient with speech-print followed by
speech feedback. Based on the findings of both studies, 2 distinct profiles of
feedback efficiency are proposed. Children that exemplify the primarily visual
profile spell words most efficiently when feedback involves print. Children that
fit the auditory profile spell words most efficiently when feedback involves
speech. The implications for understanding the learning characteristics of
children with autism, as well as those for practice and further research are
derived.

Robert.Findling@uhhs.com
OBJECTIVE: The aim of this study was to examine the effectiveness of quetiapine
in adolescents suffering from autistic disorder (AD). METHODS: This was a
12-week, open-label study, for which medically healthy patients with AD between
the ages of 10 and 17 years were eligible. Quetiapine treatment was gradually
increased over the first 6 weeks of the study, to a total daily dose of 300
mg/day. Doses could then be increased to a maximum daily dose of 750 mg/day.
Outcome measures included the Children's Psychiatric Rating Scale (CPRS) and the
Clinical Global Impressions (CGI) scale. RESULTS: Nine (9) males were enrolled.
Six (6) patients had previously been treated with other psychotropic agents.
Although improvements in several symptom domains were observed on quetiapine,
only 2 patients met a priori criteria for response ("much" or "very much
improved" on the Clinical Global Impressions-Improvement Scale). In addition,
only these same 2 patients' parents/guardians chose to continue quetiapine
pharmacotherapy after study participation. CONCLUSIONS: These data suggest that
quetiapine may not be a particularly effective agent in the treatment of
adolescent patients with AD. However, should future studies be performed, it
seems reasonable that they be conducted with more rigor, less
treatment-resistant cohorts, and, possibly, a different dosing strategy.

[Use of cholinomimetics in the treatment of endogenous autism in
children]
[Article in Russian]
[Authors not listed]
Twenty children with endogenous autism of mild and moderate severity (30-44.5
scores according to the CARS), aged 3-8 years, were treated with choline
alfoscerate (CA), 400 mg/day, during 8 weeks in the presence of maintenance
therapy with neuroleptics (17 cases). Positive therapeutic effect was observed
in 89% of the patients: significant improvement--in 61% and minimal efficacy--in
28%. Statistically significant positive changes in the patient's state were
observed in the general improvement of behavior (p<0.001), development of social
and communicative skills, as well as self-service, reduction of marked speech
disturbances (p<0.001) and motor sphere (p<0.001), enhancement of learning
activity and productivity (p<0.05). Good tolerability to the therapy, without
patient's state worsening was registered. Some patients exhibited strengthening
of affective lability in the first weeks of the treatment which attenuated to
the 4th week as the CA dosages decreased to 400 mg every other day. CA may be
recommended for combined therapy with neuroleptics as an effective and safe
medicine for the treatment of cognitive and behavioral disorders in patients
with children's autism.

[Efficacy of secretin for the treatment of autism]
[Article in Japanese]

Tokushima.
We administered secretin intravenously to 14 patients with autism (9 to 14
years, 10 males; 4 females), and evaluated its clinical effect. We also measured
cerebrospinal fluid (CSF) levels of homovanillic acid (HVA) and
5-hydroxy-indole-3-acetic acid (5HIAA) before and after 4 weeks treatment, and
compared them with the grade of improvement of the clinical symptoms assessed by
the scores of Autism Diagnostic Interview-Revised (ADI-R). After injection of
secretin, the ADI-R score increased in 8 patients, but declined in 3.
Improvement was observed in functions such as sociability (interpersonal
relationships), communication and speech improved, whereas in the others.
symptoms such as hyperkinesias and stereotyped behavior became worse. The CSF
levels of HVA was significantly increased in all of the patients showing an
improvement in the ADI-R score. SHIAA levels also tended to increase, although
this increase was not significant. These findings suggest that secretin promotes
the metabolism of serotonin and dopamine in the central nervous system, which
may contribute to improvement in clinical symptoms of autism.

The concept of autism has been broadened the last few years from 'early
infantile autism' to 'an autistic spectrum'. Autism and related contact
disorders are grouped together under 'pervasive developmental disorders' or
'autistic spectrum disorders'. The autistic disorder, Asperger's syndrome,
pervasive developmental disorder not otherwise specified (PDD-NOS), Rett's
disorder and the childhood disintegrative disorder all belong to this group.
People with an autistic spectrum disorder have severe difficulties in the
integration of perceived stimuli into a meaningful entity. More than two-thirds
of the people with the autistic disorder (classical autism) are also mentally
retarded. Although autism can still only be diagnosed at the behavioural level,
there is considerable consensus regarding an underlying organic aetiology.
Autism is clearly a multifactorial condition. Autism cannot be cured, but
adequate intervention can significantly improve the quality of life of people
with this disorder. Diagnosis and intervention are highly interrelated. In the
intervention, a distinction is made between family-oriented and child-oriented
strategies. Augmentative communication plays a key role in the treatment. People
with autism need a lot of structure, clarity and predictability, also when they
have become adults.

Treating autistic spectrum disorders in children: utility of the
cholinesterase inhibitor rivastigmine tartrate.
Chez MG, Aimonovitch M, Buchanan T, Mrazek S, Tremb RJ.
Autism and Epilepsy Specialty Services of Illinois, Ltd., USA. mchezmd@sbcglobal.net
Rivastigmine tartrate is a dual-action cholinesterase inhibitor shown to improve
language, cognition, and global functioning in patients with Alzheimer's
disease, likely via increased availability of cerebral acetylcholine. Because
cholinergic receptor abnormalities can contribute to the neuropathology of
autistic spectrum disorders, rivastigmine tartrate could prove to be an
effective therapy for affected children. Observations of improved behavior and
language output from prior open-label and double-blind treatment of autistic
children with donepezil, another cholinesterase inhibitor, prompted this 12-week
open-label study with rivastigmine tartrate of 32 autistic patients. Therapeutic
indices were the Childhood Autistic Rating Scale, Gardner's Expressive and
Receptive One-Word Picture Vocabulary tests, and the Conners' Parent Rating
Scale. Testing administered at baseline, 6 weeks, and 12 weeks showed gains in
both expressive speech and overall autistic behavior over baseline. These
improvements were statistically significant and supported the hypothesis that
treatment with cholinergic enhancing drugs in autistic spectrum disorders yields
positive therapeutic effects.

Summary Objective: Autism is a childhood-onset disorder of
unknown, possibly of multiple aetiologies. The core symptoms of
autism are abnormalities in social interaction, communication
and behaviour. The involvement of neurotransmitters such as 5-HT
has been suggested in neuropsychiatric disorders and particularly
in autistic disorder. Increased platelet 5-HT levels were found
in 40% of the autistic population, suggesting that hyperserotonaemia
may be a pathologic factor in infantile autism. Therefore, it
is of interest to assess the efficacy of cyproheptadine, a 5-HT2
antagonist in the treatment of autistic disorder. In this 8-week
double-blind, placebo-controlled trial, we assessed the effects
of cyproheptadine plus haloperidol in the treatment of autistic
disorder. Methods: Children between the ages 3 and 11 years (inclusive)
with a DSM IV clinical diagnosis of autism and who were outpatients
from a specialty clinic for children at Roozbeh Psychiatric Teaching
Hospital were recruited. The children presented with a chief complaint
of severely disruptive symptoms related to autistic disorder.
Patients were randomly allocated to cyproheptadine + haloperidol
(Group A) or haloperidol + placebo (Group B) for an 8-week, double-blind,
placebo-controlled study. The dose of haloperidol and cyproheptadine
was titrated up to 0.05 and 0.2 mg/kg/day respectively. Patients
were assessed by a third-year resident of psychiatry at baseline
and after 2, 4, 6 and 8 weeks of starting medication. The primary
measure of the outcome was the Aberrant Behaviour Checklist-Community
(ABC-C) and the secondary measure of the outcome was the Childhood
Autism Rating Scale (relating to people and verbal communication).
Side effects and extrapyramidal symptoms were systematically recorded
throughout the study and were assessed using a checklist and the
Extrapyramidal Symptoms Rating Scale, administered by a resident
of psychiatry during weeks 1, 2, 4, 6 and 8. Results: The ABC-C
and the Childhood Autism Rating Scale scores improved with cyproheptadine.
The behaviour of the two treatments was not homogeneous across
time (groups-by-time interaction, Greenhouse-Geisser correction;
F = 7.30, d.f. = 1.68, P = 0.002; F = 8.21, d.f. = 1.19, P = 0.004
respectively). The difference between the two treatments was significant
as indicated by the effect of group, and the between-subjects
factor (F = 4.17, d.f. = 1, P = 0.048; F = 4.29, d.f. = 1, P =
0.045 respectively). No significant difference was observed between
the two groups in terms of extrapyramidal symptoms (P = 0.23).
The difference between the two groups in the frequency of side
effects was not significant. Conclusion: The results suggest that
the combination of cyproheptadine with a conventional antipsychotic
may be superior to conventional antipsychotic alone for children
with autistic disorder. However the results need confirmation
by a larger randomized controlled trial.

Psychoeducational treatment of children with autism
and reactive attachment disorder.
Mukaddes NM, Kaynak FN, Kinali G, Besikci H, Issever H.
University of Istanbul, Istanbul, Turkey. nmotavalli@yahoo.com
The aim of the study was to evaluate and compare the efficacy
of short-term psychoeducational treatment in children with autism
and reactive attachment disorder (RAD). Ten boys with autism aged
24-66 months and 11 children with RAD (nine boys and two girls)
aged 30-70 months were included in the study. The Ankara Developmental
Screening Inventory was used to monitor progress following a 14-session
psychoeducational programme. This focused on establishing a reciprocal-dyadic
interaction between children and their caregivers and it also
provided an educational programme for emotional, social, and language
development. Although both groups showed significant changes on
all scales of the ADSI, the children with RAD showed greater improvement
than the autism group in their total development score, on the
language-cognitive subscale, and in social/self-care abilities.

Effects of peer training and written text cueing
on social communication of school-age children with pervasive
developmental disorder.
Thiemann KS, Goldstein H.
Juniper Gardens Children's Project, Kansas City, KS 66101-2800,
USA. thiemann@ku.edu
This study consecutively examined the effects of 2 social interventions--
peer training and written text treatment--on the social communication
of 5 elementary students with pervasive developmental disorder.
Each child with autism was paired with 2 peers without disabilities
to form 5 triads. In Intervention 1 (peer training), peers were
taught to use 5 facilitative social skills over 5 days. After
peer training, 4 children with autism increased or used more stable
rates of initiations and contingent responses overall. However,
all children continued to demonstrate deficits in specific social-communication
skills. Once Intervention 2 (direct instruction using written
text cues) was implemented, increased use of 3 different communication
skills was observed across all 5 participants. In addition, social
validity outcomes revealed improved quality of child-peer interactions,
2 teacher reports of improved social skill development, and improved
acceptance and friendship ratings for the children with autism.
Results support the use of written text cues to improve children's
social communication with peers, and suggest that combining approaches
may be necessary to improve the quality of children's relationships.

The effect of a switch to ziprasidone in an adult
population with autistic disorder: chart review of naturalistic,
open-label treatment.
Cohen SA, Fitzgerald BJ, Khan SR, Khan A.
1315 1st Ave. N., Seattle, WA 98109, USA. sacohenmd@msn.com
BACKGROUND: The present investigation retrospectively assessed
the effect of an open-label switch to ziprasidone from other atypical
antipsychotics on behavior, weight, and lipid levels in an adult
population with autistic disorder. METHOD: We conducted a chart
review of 10 adults (mean +/- SD age = 43.8 +/- 6.0 years) with
DSM-IV autistic disorder who were switched from other atypical
antipsychotics to ziprasidone, primarily due to weight gain, but
other reasons included hypercholesterolemia, maladaptive behaviors,
drowsiness, and depression. They had been treated with ziprasidone
for at least 6 months. Our review focused on frequency of maladaptive
behaviors, weight, and lipid levels. RESULTS: The mean +/- SD
daily dose of ziprasidone was 128 +/- 41 mg, and all 10 patients
continued with this same treatment after completion of the 6-month
trial. Seven patients were found to have an improvement or no
change in their maladaptive behavior. Eight patients (80%) lost
weight (mean change = -13.1 +/- 7.0 lb [-5.9 +/- 3.2 kg]), 4 (80%)
of 5 patients had a decrease in total cholesterol level, and 3
(60%) of 5 had a decrease in triglyceride levels. Data on lipid
levels were available for 5 of the 10 patients. Behavioral activation
was not noted in this population. There were no significant adverse
effects associated with ziprasidone. CONCLUSION: In adults with
autism, a switch to ziprasidone from other atypical antipsychotics
appears to have the potential for maintaining beneficial effect
on behavior while improving major health indices including weight
and lipid levels.

Clinical effects of risperidone were evaluated in 9 young autistic
children under informed consent of their parents. The patients
were evaluated by the Children's Behavioral Checklist and Rutter's
Autistic Behavioral Rating Scale. After the administration, two
subjects (playing and adaptation to change) of the Children's
Behavioral Checklist and four (anomalous autistic behavior, destructive
behavior, developmental problem and activity level) of the Rutter's
Autistic Behavioral Rating Scale were improved significantly.
There were no serious side effects such as extrapyramidal symptoms
except minor adverse effects including sedation, depression, increased
appetite and constipation. Risperidone might be effective for
serious behavioral disturbances in young autistic children.

Autism is a neurologic disorder with impairments in language,
social communication, and behavior, which may improve over time,
but which persist throughout the lifetime. The evaluation of autism
requires a separation of clinical and research objectives and
is done best in close cooperation with professionals in the fields
of communication, education, and psychology. There are no biologic
markers of autism. Regression in language and social communication
is present in approximately 30% of children with autism and is
most likely to occur between 18 and 24 months of age. Early deficits
in social communication can be identified by the assessment of
joint attention, affective reciprocity, and metacognition. Current
evidence suggests that deficits in social cognition and communication
in autism may be related to dysfunction in the amygdala, hippocampus,
and related limbic and cortical structures. Other neuroanatomic
structures, such as the cerebellum, also may form part of a distributed
neuronal network responsible for social cognition and communication.
Genetics play a major role in autism, but what is inherited and
how broad the inheritable phenotype is remain unclear. At a neurochemical
level, the principal neurotransmitter implicated in autism is
serotonin. Seizures and epileptiform discharges are common in
autism and are linked to cognitive dysfunction. The role of medication
is to target specific symptoms and open windows of opportunity
that allow implementation of a multimodal individualized educational
plan.

Autism is a pervasive developmental disorder of childhood characterised
by disturbances in both social interactions and communication
as well as stereotyped patterns of activities and behaviour. The
increase in estimates of the prevalence of autism has raised the
question of an "epidemic" of autism. More active case
assessment and changes in diagnostic criteria probably account
in large part for such increase. Investigators have attempted
to define the neural pathophysiology of autism ever since the
hypothesis of "refrigerator mother" as its cause was
replaced by the view that it is a developmental disorder of the
immature brain. However consensus is yet to be reached concerning
the brain regions implicated. Psychoanalysis, cognitive psychology,
neurophysiology, neuropharmacology, and genetics propose restricted
view of the major issues leaving extensive areas unexplored. Therapeutic
approaches induce only partial and uncertain results. There is
no cure for autism but substantial evidence indicates that early,
intensive, individualised education is beneficial for children.
All modern intervention programs for autism affected children
share a high degree of environmental structuring and predictability
and an extensive individual approach. Autism being a behaviourally
defined syndrome, it gave rise to a number of controversies concerning
definition, classification, etiopathogenesis and therapeutics.
In the 1990s a crisis has occurred in France with a loss of confidence
between parents and psychiatrists with a problem concerning the
means and ways of care of the autistic individual. The aim of
this paper is to point out the different questions raised by autism
in order to better understand this syndrome which touches upon
essential behaviour-related aspects such as self consciousness,
reality perception, the functioning of the thought and communication,
as well as the role of hereditary and acquired influences in normal
and pathological development.

Psychiatry, Calambrone, Pisa, Italy. gabriele.masi@inpe.unipi.it
BACKGROUND: Only sparse and short-term data are available on
pharmacologic treatments in very young children with pervasive
developmental disorders (PDD). The purpose of this 3-year naturalistic
study (March 1999-April 2002) is to describe the clinical outcome
of a consecutive sample of preschool children with PDD treated
with risperidone monotherapy. METHOD: The sample consisted of
45 boys and 8 girls aged 3.6 to 6.6 years (mean +/- SD age = 4.6
+/- 0.7 years) with a DSM-IV diagnosis of autistic disorder or
PDD, not otherwise specified. Outcome measures included the Children's
Psychiatric Rating Scale (CPRS), Clinical Global Impressions-Improvement
scale (CGI-I), Children's Global Assessment Scale (CGAS), and
a checklist for risperidone side effects. RESULTS: Patients received
risperidone for a period ranging from 1 to 32 months (7.9 +/-
6.8 months). Twenty-five patients (47.2%) continued to receive
risperidone after the study was completed, while 28 (52.8%) discontinued
due to side effects (22.6% [N = 12]), parents' choice (18.9% [N
= 10]), lack of efficacy (5.7% [N = 3]), and decision of the treating
psychiatrist (5.7% [N = 3]). The optimal dose was 0.55 +/- 0.2
mg/ day. Significant improvement at the last observation was found
in CPRS (p < .0001) and CGAS (p < .0001) scores. On the
basis of both an improvement of 25% in CPRS score and a score
of 1 or 2 on the CGI-I, 46.8% (N = 22) of subjects were considered
responders. Behavioral disorders and affect dysregulation were
more sensitive to treatment than was interpersonal functioning.
Responders received higher doses of medication for a longer period
and had a greater weight gain than did nonresponders. Increased
prolactin levels without clinical signs (65% [24 of 37]) and increased
appetite (15% [8 of 531) were the most frequent side effects.
CONCLUSION: These findings suggest that low-dose risperidone may
positively affect the clinical outcome in young children with
PDD not only in the short-term, but also in the long-term period.

Can early interventions alter the course of autism?
Howlin P.
Department of Psychology, St. George's Hospital Medical School,
Cranmer Terrace, London SW17 0RE, UK.
Interventions for autism have come a long way since the condition
was described by Kanner in the 1940s. At that time, autism was
considered to be closely linked to schizophrenia, and inadequate
parenting was viewed as the principal cause. Psychoanalysis was
often the therapy of choice, but there was also widespread use
of the drugs and even electroconvulsive treatments that had been
developed for use in schizophrenia. Over the years, as autism
has come to be recognized as a developmental disorder, interventions
have focused instead on enhancing developmental skills and on
ways of ameliorating behavioural difficulties. Recognition of
the role that language deficits in particular play in causing
behaviour problems has led to a focus on the teaching of more
effective communication skills. The need for early support for
families and appropriate education is also widely acknowledged.
Nevertheless, follow-up studies indicate that the prognosis for
the majority of individuals with autism remains poor. And despite
claims to the contrary, there is little evidence that very early,
intensive interventions can significantly alter the long-term
course of the disorder. The paper discusses findings from follow-up
studies over the years and assess the impact of different intervention
procedures on outcome.

Why have drug treatments been so disappointing?
Buitelaar JK.
University of Medical Center Utrecht, Department of Child and
Adolescent Psychiatry, B.01.324, PO Box 85500, 3508 GA Utrecht,
The Netherlands.
The title of this contribution involves two consecutive questions:
have the effects of medication in autism indeed been disappointing?
And if so, why? The answer to the first question depends on whether
one focuses on the core social and communicative deficits of autism,
or on various complicating behaviour problems. Attempts over the
past decades to develop drugs that specifically improve social
and communicative functioning have failed. Among the most ambitious
attempts were medical interventions in the endogenous opioid system
that were motivated from animal models on the involvement of this
system in various aspects of social behaviour. By contrast, medications
such as the newer antipsychotics, psychostimulants, presynaptic
noradrenergic blocking agents (clonidine and guanfacine) and selective
serotonin reuptake inhibitors were shown to reduce impairing complicating
symptoms of affective instability, irritability, hyperactivity
and inattentiveness, aggression, self-injury and stereotypies.
The explanation for the medication-refractory status of social
and communicative deficits should be sought in at least two related
factors: (1) the as yet unidentified neurochemical basis of autism,
and (2) the obvious lack of involvement of the main neurotransmitter
systems (dopamine, noradrenaline and serotonin) in the pathophysiology
of social and communicative behaviour.

The neuropathology of the autism spectrum disorders:
what have we learned?
Bauman ML, Kemper TL.
Children's Neurology Service, Massachusetts General Hospital,
55 Fruit Street, Boston, MA 02114, USA.
Autism is a behaviourally defined disorder, initially described
by Kanner in 1943. By definition, symptoms are manifested by 36
months of age and are characterized by delayed and disordered
language, impaired social interaction, abnormal responses to sensory
stimuli, events and objects, poor eye contact, an insistence on
sameness, an unusual capacity for rote memory, repetitive and
stereotypic behaviour and a normal physical appearance. Relatively
few neuropathological studies have been performed on the brains
of autistic subjects. Of those reported, abnormalities have been
described in the cerebral cortex, the brainstem, the limbic system
and the cerebellum. Although those with the disorder present with
a specific set of core characteristics, each individual patient
is somewhat different from another. Thus, it should not be surprising
that the brains of these subjects should show a wide range of
abnormalities. However, it is important to delineate the anatomic
features, which are common to all cases, regardless of age, sex
and IQ, in order to begin to understand the central neurobiological
profile of this disorder. The results of our systematic studies
indicate that the anatomic features that are consistently abnormal
in all cases include reduced numbers of Purkinje cells in the
cerebellum, and small tightly packed neurons in the entorhinal
cortex and in the medially placed nuclei of the amygdala. It is
known that the limbic system is important for learning and memory,
and that the amygdala plays a role in emotion and behaviour. Research
in the cerebellum indicates that this structure is important as
a modulator of a variety of brain functions and impacts on language
processing, anticipatory and motor planning, mental imagery and
timed sequencing. Defining the differences and similarities in
brain anatomy in autism and correlating these observations with
detailed clinical descriptions of the patient may allow us greater
insight into the underlying neurobiology of this disorder.

[The effect of cerebrolysin on cognitive functions
in childhood autism and in Asperger syndrome]
[Article in Russian]
Krasnoperova MG, Bashina VM, Skvortsov IA, Simashkova NV.
Nineteen children with childhood autism and 8 with Asperger's
syndrome aged 2-8 year, were treated with cerebrolysin (CL) in
inpatient clinic. All the patients received 10 microinjections
(intramuscularly and perinervously) of 0.1 ml CL daily during
5 days. Clinical study was combined with device estimation of
cognitive functions and communicative skills. CL therapy resulted
in improvement of cognitive functions (expressive and receptive
speech, fine motoring, playing). Positive effects were revealed
in all the patients with Asperger's syndrome and in 89% of the
patients with childhood autism. Any negative effects were not
found. With regard to cognitive functions development, therapeutic
efficacy proved to be more pronounced in the patients with Asperger's
syndrome as compared to childhood autistic group (p < 0.005).

Autism.
Volkmar FR, Pauls D.
Child Study Center, Yale University, PO Box 207900, New Haven,
CT 06520, USA. fred.volkmar@yale.edu
Autism is a disorder characterised by severe difficulties in
social interaction and communication, and with unusual behaviours.
Once thought of as rare, autism is now recognised as being common.
The role of CNS factors in pathogenesis is suggested by high rates
of seizure disorder; research has highlighted the role of several
specific brain regions in syndrome pathogenesis. Autism is a strongly
genetic disorder and probably arises because of multiple genes;
recurrence rates in families with one child are high. Early intervention
with various techniques is helpful in many cases. Some pharmacological
agents may help with certain problematic behaviours but do not
address the underlying cause of the disorder.

AIMS: To examine the effect of a single dose of human synthetic
secretin (HSS) on behaviour and communication in children with
autism spectrum disorder (ASD) using an objective measure of communication
and social reciprocity and standardised rating scales. METHODS:
Randomised, crossover, double blind, and placebo controlled trial
of a single intravenous dose of human synthetic secretin (HSS)
2 CU/kg. The 62 subjects (3-8 years) were assigned to group 1
(saline placebo/HSS) or group 2 (HSS/saline placebo). Diagnosis
was confirmed by ADI-R (Autism Diagnostic Interview-Revised) algorithm.
Severity of symptoms was rated using the CARS (Childhood Autism
Rating Scale). Outcome measures included Communication and Symbolic
Behavior Scale (CSBS), Ritvo Real-life Rating Scale, weekly Global
Rating Scale (GBRS) by parents and teachers, and daily log of
gastrointestinal symptoms. The communication subscale of the CSBS,
specifying communication function, reciprocity, and social-affective
signalling was videotaped and scored by a blinded, trained observer.
RESULTS: Sixty one children completed the study. After randomisation,
there were no significant differences in gender, race, age, and
parent and teacher GBRS and Ritvo Scale between the two groups.
Compared with placebo, secretin treatment was not associated with
significant improvement of CSBS standard scores from baseline
to 2 or 4 weeks post-infusion. Five children showed clinical improvement
in standard scores: two after HSS and three after placebo. There
were no significant changes in gastrointestinal symptoms after
HSS or saline placebo. CONCLUSIONS: A single dose of intravenous
human secretin is not effective in changing behaviour and communication
in children with ASD when compared to placebo.

PA 19104, USA.
BACKGROUND: Standardised measures of behaviour have failed
to detect short term improvement in children with autism following
treatment with secretin. However, it is possible that standardised
measures are insensitive to dimensions of child behaviour that
are nonetheless detectable by parents. AIM: To determine the ability
of parents of children with autism to guess, under double blind
conditions, whether their child had received secretin or placebo.
METHODS: 2x2 crossover randomised blinded study, comparing the
effect of synthetic human secretin 2 U/kg to placebo (saline).
Sixty two children with autism (aged 43-103 months) were randomly
allocated to two groups: group 1 received placebo, followed six
weeks later by secretin, and group 2 received secretin followed
by placebo. At the conclusion of the study, parents were asked
to guess their child's group assignment. RESULTS: Twenty seven
families guessed their child's group assignment correctly and
27 guessed incorrectly. In 48 instances, parents based their guess
on perceived improvement; in six cases, parents based their guess
on perceived deterioration. Six families saw no difference after
either infusion, and offered no guess. One family dropped out
after the first infusion, and one family was lost to follow up
after the second infusion. CONCLUSION: In a controlled setting,
parents of young children with autism are unable to distinguish
the short term behavioural effects of secretin from placebo.

[Studies on the adverse effects of fluvoxamine
treatment in children with autistic disorder: correlation with
genetic polymorphism in serotonin related genes]
[Article in Japanese]

Selective serotonin re-uptake inhibitors (SSRIs) have recently
been applied to the children with autistic disorder. To create
better treatment, we studied here clinical adverse effects of
fluvoxamine and correlated them with genetic polymorphism of two
genes, the promoter region of serotonin transporter gene (5-HTTLPR)
and serotonin 2A receptor gene (5-HT2AR). Twenty-eight subjects,
consisting of 23 boys and 5 girls, aged from 3 to 18 years old
diagnosed as having autistic disorder were analyzed during fluvoxamine
administration. The dosages and duration of fluvoxamine treatment
are 1.5 to 3 mg/kg/day and 2 weeks to 17 months (mean 7.9 months),
respectively. There were several clinical adverse effects such
as sleep disturbance in 9 cases, climb up to high places in 8,
gastrointestinal symptoms in 6, hyperactivities in 5, excitement
in 4, general fatigability in 2 and urticaria in 1. Medication
was discontinued in 2 patients with fatigability and 1 with sleep
disturbance, diarrhea and poor appetite. There was no significant
correlation between genetic polymorphism in 5-HTTLPR and the occurrence
of clinical adverse effects of fluvoxamine. However hyperactivity
was significantly more frequent in the subjects with 102T/102T
polymorphism of 5-HT2AR, and patients with sleep disturbance were
significantly less frequent in the subjects with 102C/102C polymorphism.
We conclude that the clinical adverse effects such as climb up
to high places and hyperactivity during fluvoxamine treatment
may be relatively specific in children, and that genetic polymorphism
of 5-HT2AR may be related to the appearance of clinical adverse
effects.

Effects of in-home training for culturally diverse
fathers of children with autism.

elderjh@nursing.ufl.edu
Recently there has been mounting interest in the role of fathers
and the effect of their increasing involvement on child development.
However, to date, little has been reported regarding the role
of fathers with developmentally delayed children (e.g., autism,
pervasive developmental delays) and cultural influences on father-child
interactions. In this article we address this knowledge gap by
reporting four cases representing the major ethnic groups. For
each case, we (1) define the concept of fatherhood in its cultural
context, (2) review and summarize related father-child research,
and (3) present findings from our study evaluating the effects
of an in-home intervention for autistic children. While variability
is noted within and among the culturally diverse father-child
dyads, there are also similarities across ethnic groups. Results
of this study are promising, demonstrating the value of single
subject experimental methods in characterizing and beginning to
understand complex father-child interactions in autism and related
child psychiatric disorders.

Use of citalopram in pervasive developmental disorders.
Namerow LB, Thomas P, Bostic JQ, Prince J, Monuteaux MC.
Department of Psychiatry, Hartford Hospital, University of Connecticut
School of Medicine, Hartford, Connecticut 06106, USA.
This study assessed the effectiveness and tolerability of the
selective serotonin reuptake inhibitor citalopram in the treatment
of patients with pervasive developmental disorders (PDDs). The
medical charts of 15 children and adolescents (aged 6-16 yr) with
Asperger syndrome, autism, or PDD not otherwise specified treated
with citalopram were retrospectively reviewed. The final dose
of citalopram was 16.9 +/- 12.1 mg/day with a treatment duration
of 218.8 +/- 167.2 days. Independent ratings of the Clinical Global
Impression (CGI) Severity and Improvement scales allowed comparison
between baseline and PDD symptoms at the last visit. Eleven adolescents
(73%) exhibited significant improvement in PDD, anxiety, or mood
CGI score (z = 2.95; p =.003). Anxiety symptoms associated with
PDDs improved significantly in 66% of patients (z = 2.83, p =.005),
and mood symptoms improved significantly in 47% of patients (z
= 2.78, p =.005). Mild side effects were reported by five patients
(33%). These data suggest citalopram may be effective, safe, and
well tolerated as part of the treatment of PDDs.

Joint attention training for children with autism
using behavior modification procedures.
Whalen C, Schreibman L.
Autism Spectrum Therapies, Los Angeles, CA 90034, USA. cdallaire@autismtherapies.com
BACKGROUND: Deficits in joint attention are considered by many
researchers to be an early predictor of childhood autism (e.g.,
Osterling & Dawson, 1994) and are considered to be pivotal
to deficits in language, play, and social development in this
population (Mundy, 1995). Although many researchers have noted
the importance of joint attention deficits in the development
of children with autism (e.g., Mundy, Sigman, & Kasari, 1994)
and have called for intervention strategies (e.g., Mundy &
Crowson, 1997), few studies have attempted to target joint attention.
In this study, joint attention behaviors were taught to children
with autism using a behavior modification procedure. METHODS:
A multiple-baseline design was implemented to evaluate intervention
effects. The following target behaviors were included in the intervention:
1) Responding to showing, pointing, and gaze shifting of adult;
2) Coordinated gaze shifting (i.e., coordinated joint attention);
and 3) Pointing (with the purpose of sharing, not requesting).
Generalization to setting and parent, follow-up sessions, and
social validation measures were also analyzed. RESULTS: Joint
attention behaviors were effectively trained and targeted behaviors
generalized to other settings. In addition, positive changes were
noted by naive observers using social validation measures. CONCLUSIONS:
Integrating joint attention training into existing interventions
may be important for children with autism. In addition, training
parents in these techniques may help to maintain joint attention
skills outside of the treatment setting.

A pilot prospective follow-up study of the role of the ketogenic
diet was carried out on 30 children, aged between 4 and 10 years,
with autistic behavior. The diet was applied for 6 months, with
continuous administration for 4 weeks, interrupted by 2-week diet-free
intervals. Seven patients could not tolerate the diet, whereas
five other patients adhered to the diet for 1 to 2 months and
then discontinued it. Of the remaining group who adhered to the
diet, 18 of 30 children (60%), improvement was recorded in several
parameters and in accordance with the Childhood Autism Rating
Scale. Significant improvement (> 12 units of the Childhood
Autism Rating Scale) was recorded in two patients (pre-Scale:
35.00 +/- 1.41[mean +/- SD]), average improvement (> 8-12 units)
in eight patients (pre-Scale: 41.88 +/- 3.14[mean +/- SD]), and
minor improvement (2-8 units) in eight patients (pre-Scale: 45.25
+/- 2.76 [mean +/- SD]). Although these data are very preliminary,
there is some evidence that the ketogenic diet may be used in
autistic behavior as an additional or alternative therapy.

Parent-mediated early intervention for young children
with autism spectrum disorder.
Diggle T, McConachie HR, Randle VR.
Department of Child Health, The University of Newcastle, University
of Newcastle, Newcastle upon Tyne, UK, NE2 4AE. T.J.Diggle@newcastle.ac.uk
BACKGROUND: Recent estimates concerning the prevalence of autistic
spectrum disorder are much higher than those reported 30 years
ago, with at least 1 in 400 children affected. This group of children
and families have important service needs. The involvement of
parents in implementing intervention strategies designed to help
their autistic children has long been accepted as helpful. The
potential benefits are increased skills and reduced stress for
parents as well as children. OBJECTIVES: The objective of this
review was to determine the extent to which parent-mediated early
intervention has been shown to be effective in the treatment of
children aged 1 year to 6 years 11 months with autistic spectrum
disorder. In particular, it aimed to assess the effectiveness
of such interventions in terms of the benefits for both children
and their parents. SEARCH STRATEGY: A range of psychological,
educational and biomedical databases were searched. Bibliographies
and reference lists of key articles were searched, field experts
were contacted and key journals were hand searched. SELECTION
CRITERIA: Only randomised or quasi-randomised studies were included.
Study interventions had a significant focus on parent-implemented
early intervention, compared to a group of children who received
no treatment, a waiting list group or a different form of intervention.
There was at least one objective, child related outcome measure.
DATA COLLECTION AND ANALYSIS: Appraisal of the methodological
quality of included studies was carried out independently by two
reviewers. Differences between the included studies in terms of
the type of intervention, the comparison groups used and the outcome
measures were too great to allow for direct comparison. MAIN RESULTS:
The results of this review are based on data from two studies.
Two significant results were found to favour parent training in
one study: child language and maternal knowledge of autism. In
the other, intensive intervention (involving parents, but primarily
delivered by professionals) was associated with better child outcomes
on direct measurement than were found for parent-mediated early
intervention, but no differences were found in relation to measures
of parent and teacher perceptions of skills and behaviours. REVIEWER'S
CONCLUSIONS: This review has little to offer in the way of implications
for practice: there were only two studies, the numbers of participants
included were small, and the two studies could not be compared
directly to one another. In terms of research, randomised controlled
trials involving large samples need to be carried out, involving
both short and long-term outcome information and full economic
evaluations. Research in this area is hampered by barriers to
randomisation, such as availability of equivalent services.

L-Carnosine, a dipeptide, can enhance frontal lobe function
or be neuroprotective. It can also correlate with gamma-aminobutyric
acid (GABA)-homocarnosine interaction, with possible anticonvulsive
effects. We investigated 31 children with autistic spectrum disorders
in an 8-week, double-blinded study to determine if 800 mg L-carnosine
daily would result in observable changes versus placebo. Outcome
measures were the Childhood Autism Rating Scale, the Gilliam Autism
Rating Scale, the Expressive and Receptive One-Word Picture Vocabulary
tests, and Clinical Global Impressions of Change. Children on
placebo did not show statistically significant changes. After
8 weeks on L-carnosine, children showed statistically significant
improvements on the Gilliam Autism Rating Scale (total score and
the Behavior, Socialization, and Communication subscales) and
the Receptive One-Word Picture Vocabulary test (all P < .05).
Improved trends were noted on other outcome measures. Although
the mechanism of action of L-carnosine is not well understood,
it may enhance neurologic function, perhaps in the enterorhinal
or temporal cortex.

Social interactions of children with autism in
father-child and mother-child play sessions.
Elder JH, Valcante G, Groce S, Yarandi H, Carlton MS.
University of Florida, College of Nursing, Gainesville, FL, USA.
Autism, or the broader category of autistic spectrum disorder
(ASD), is a complex developmental disability characterized by
qualitative impairments in social interaction and communication
and restricted repetitive patterns of behavior. Specific aims
of the investigation reported here were to (a) compare autistic
child behaviors in clinic versus home settings, (b) compare father
and mother behaviors in clinic versus home settings, and (c) characterize
interactions of fathers with their autistic children and compare
these with mother-child interactions. While results indicated
that there were no statistically significant group differences
between child behaviors in clinic versus home settings or in father
versus mother behaviors, there was wide behavioral variability
in each setting and differences when comparing individual cases.
These findings are consistent with the clinical impression that
autism is a syndrome with various symptom configurations and individual
differences in behaviors.

Contextualized behavioral support in early intervention
for children with autism and their families.
Moes DR, Frea WD.
University of California, Los Angeles, USA.
Parent education programs have become an effective mode of
treatment delivery for teaching families effective behavioral
strategies to manage challenging behavior in young children with
autism. Functional assessment and functional communication training
(FCT) are empirically validated procedures that have recently
been introduced into parent education programming to help resolve
challenging behaviors. The success of these procedures, however,
is contingent on family members' ability to integrate them into
the specific contexts in which challenging behaviors occur. Consequently,
the application of these procedures in home settings necessitates
consideration of the family context in the assessment and treatment
planning process. A study is presented that investigated the use
of information on family context (i.e., caregiving demands, family
support, patterns of social interaction) to direct the assessment
and intervention planning process. More specifically, information
on family context was used to individualize behavioral support
plans designed to support family use of functional communication
training within important family routines. Through parent-investigator
collaboration we individualized the manner in which functional
communication training procedures were taught and implemented
so they were contextually relevant. Utilizing a multiple baseline
design, the challenging behaviors and functional communication
of three children with autism were monitored across baseline,
intervention (i.e., FCT, and contextulized FCT), and follow-up
phases. Multiple routines for each participant were selected and
monitored across all phases to evaluate changes in the dependent
measures within training and generalization routines. A self-report
questionnaire was administered intermittently to parents to determine
if consideration of family context improved the "goodness
of fit" of the functional communication training treatment
packages across FCT and contextualized FCT intervention phases.
Results from the study indicate that consideration of family context
in the assessment and intervention planning process does not jeopardize
and may contribute to the stability and durability of reductions
in challenging behavior achieved with functional assessment and
functional communication training procedures.

Sinai School of Medicine, New York, NY 10029, USA. eric.hollander@mssm.edu
Autism is a neurodevelopmental disorder characterized by dysfunction
in three core behavioral domains: repetitive behaviors, social
deficits, and language abnormalities. There is evidence that abnormalities
exist in peptide systems, particularly the oxytocin system, in
autism spectrum patients. Furthermore, oxytocin and the closely
related peptide vasopressin are known to play a role in social
and repetitive behaviors. This study examined the impact of oxytocin
on repetitive behaviors in 15 adults with autism or Asperger's
disorder via randomized double-blind oxytocin and placebo challenges.
The primary outcome measure was an instrument rating six repetitive
behaviors: need to know, repeating, ordering, need to tell/ask,
self-injury, and touching. Patients with autism spectrum disorders
showed a significant reduction in repetitive behaviors following
oxytocin infusion in comparison to placebo infusion. Repetitive
behavior in autism spectrum disorders may be related to abnormalities
in the oxytocin system, and may be partially ameliorated by synthetic
oxytocin infusion.

BACKGROUND: Atypical antipsychotic agents, which block postsynaptic
dopamine and serotonin receptors, have advantages over traditional
antipsychotic medications in the treatment of adults with schizophrenia
and may be beneficial in children with autistic disorder who have
serious behavioral disturbances. However, data on the safety and
efficacy of atypical antipsychotic agents in children are limited.
METHODS: We conducted a multisite, randomized, double-blind trial
of risperidone as compared with placebo for the treatment of autistic
disorder accompanied by severe tantrums, aggression, or self-injurious
behavior in children 5 to 17 years old. The primary outcome measures
were the score on the Irritability subscale of the Aberrant Behavior
Checklist and the rating on the Clinical Global Impressions -
Improvement (CGI-I) scale at eight weeks. RESULTS: A total of
101 children (82 boys and 19 girls; mean [SD] age, 8.82.7 years)
were randomly assigned to receive risperidone (49 children) or
placebo (52). Treatment with risperidone for eight weeks (dose
range, 0.5 to 3.5 mg per day) resulted in a 56.9 percent reduction
in the Irritability score, as compared with a 14.1 percent decrease
in the placebo group (P<0.001). The rate of a positive response,
defined as at least a 25 percent decrease in the Irritability
score and a rating of much improved or very much improved on the
CGI-I scale, was 69 percent in the risperidone group (34 of 49
children had a positive response) and 12 percent in the placebo
group (6 of 52, P<0.001). Risperidone therapy was associated
with an average weight gain of 2.72.9 kg, as compared with 0.82.2
kg with placebo (P<0.001). Increased appetite, fatigue, drowsiness,
dizziness, and drooling were more common in the risperidone group
than in the placebo group (P<0.05 for each comparison). In
two thirds of the children with a positive response to risperidone
at eight weeks (23 of 34), the benefit was maintained at six months.
CONCLUSIONS: Risperidone was effective and well tolerated for
the treatment of tantrums, aggression, or self-injurious behavior
in children with autistic disorder. The short period of this trial
limits inferences about adverse effects such as tardive dyskinesia.

Levetiracetam in autistic children: an open-label
study.
Rugino TA, Samsock TC.
Department of Pediatrics, Marshall University Joan C Edwards School
of Medicine, Huntington, West Virginia, USA. drtomrug@mac.com
The objectives of this study were to determine whether autistic
children taking levetiracetam (1) showed improvement in the areas
of aggression, impulsivity, hyperkinesis, and mood instability,
and (2) showed a nootropic response. Ten white autistic boys ranging
from 4 to 10 years were compared pretreatment and while taking
levetiracetam for an average of 4.1 weeks. Inattention, hyperkinesis,
and impulsivity were evaluated using the Achenbach Attention Problems
scale, Conners DSM-IV Total scale, and the Conners Attention-Deficit
Hyperactivity Disorder Index scale, all of which showed statistically
significant improvements. Mood instability was measured with the
Conners Global Index (CGI) Emotional Lability and CGI Total scales,
both of which showed statistically significant improvements. Aggressive
behavior, as measured with the Achenbach Aggression scale, showed
statistically significant improvement only for subjects who were
not recently weaned from medications that reduce aggression (e.g.,
risperidone, carbamazepine, desipramine). Levetiracetam may reduce
hyperactivity, impulsivity, mood instability, and aggression in
autistic children with these problems. No nootropic effect was
observed.

Finland. marko.kielinen@autismiliitto.fi
Hospital records and data on the treatment/habilitation status
of 187 children with autism aged 3-18 years were gathered from
Northern Finland. The treatment programs and therapies varied,
depending on the trained staff available. One-hundred and fifty-two
(82.9%) children and adolescents with autism received more than
one therapeutic intervention or specific training program. The
most common therapies were physiotherapy as well as speech, occupational
and music therapy. 43.9% of the children and adolescents with
autism received specific training according to TEACCH (Treatment
and Education of Autistic and related Communication-Handicapped
Children), 10.2% according to Lovaas and 30.5% according to the
Portage program. Antiepileptic medication had been prescribed
to 23.9% and psychopharmacological interventions to 14.9% of the
individuals with autistic disorder (AD). One hundred and seventy-eight
subjects out of 187 showed some improvement on the Childhood Autism
Rating Scale (CARS), even if no statistically significant difference
was found between the outcome of the available habilitation methods.

Do high functioning autistic individuals treated
in a residential setting differ in divided attention abilities
from those treated in an out-patient setting?
Bogte H, Flamma B, van der Meere J.
Workhome Zuidlaren, Stichting GGz Groningen, The Netherlands.
The goal of this current study was to test divided attention
abilities of a group adults with autism and normal intellectual
functioning, treated in a residential setting versus those treated
in an out-patient setting. Both groups were compared with a control
group using the Sternberg (1969) reaction time paradigm. It appeared
that the in-patient group suffered from a divided attention deficit
compared to a norm group. The patients treated in an out-patient
setting scored in between the norm group and the in-patient group.
Findings are discussed with respect to the relevance for the day
to day clinical practice.

Dr, Suite 145, Orlando, Florida 32826, USA. cnye@mail.ucf.edu
BACKGROUND: The use of mega-vitamin intervention began in the
early 1950's with the treatment of schizophrenic patients. Pyroxidine
(vitamin B6) was first used with children diagnosed with "autism
syndrome" when speech and language improvement was observed
in some children as a result of large doses of B6. A number of
published studies attempted to assess the effects of vitamin B6-Mg
(Mg was found to reduce undesirable side effects from B6) on a
variety of characteristics such as verbal communication, non-verbal
communication, interpersonal skills, and physiological function,
in individuals with autism. OBJECTIVES: To determine the efficacy
of vitamin B6 and magnesium (B6-Mg) for treating social, communication
and behavioural responses of children and adults with autism.
SEARCH STRATEGY: We searched the Cochrane Controlled Trials Register

EMBASE (1980-January 2002), PsychINFO (1887 - January 2002), Dissertation
Abstracts International (1861 - January 2002). The search engine
FirstSearch was also used (January 2002). Reference lists for
all the obtained studies and other review articles were examined
for additional studies. SELECTION CRITERIA: All studies in which
the participants were randomly allocated prior to intervention
and in which outcomes were compared to either a placebo or non-treated
group were included. DATA COLLECTION AND ANALYSIS: Two reviewers
independently evaluated all potential studies identified as indicated
above for inclusion. MAIN RESULTS: Two trials were included in
the review. Both studies used a double-blind crossover design.
One study (Tolbert 1993) provided insufficient data to conduct
an analysis. The senior author was contacted for supporting data
but was unable to provide the needed information. The remaining
study (Findling, 1997) yielded no significant differences between
treatment and placebo group performances following the B6 intervention
on measures of social interaction, communication, compulsivity,
impulsivity, or hyperactivity. REVIEWER'S CONCLUSIONS: Due to
the small number of studies, the methodological quality of studies,
and small sample sizes, no recommendation can be advanced regarding
the use of B6-Mg as a treatment for autism.

Autism, an extreme challenge to integrative medicine.
Part 2: medical management.
Kidd PM.
Autism and allied autistic spectrum disorders (ASD) present
myriad behavioral, clinical, and biochemical abnormalities. Parental
participation, advanced testing protocols, and eclectic treatment
strategies have driven progress toward cure. Behavioral modification
and structured education are beneficial but insufficient. Dietary
restrictions, including removal of milk and other casein dairy
products, wheat and other gluten sources, sugar, chocolate, preservatives,
and food coloring are beneficial and prerequisite to benefit from
other interventions. Individualized IgG or IgE testing can identify
other troublesome foods but not non-immune mediated food sensitivities.
Gastrointestinal improvement rests on controlling Candida and
other parasites, and using probiotic bacteria and nutrients to
correct dysbiosis and decrease gut permeability. Detoxification
of mercury and other heavy metals by DMSA/DMPS chelation can have
marked benefit. Documented sulfoxidation-sulfation inadequacies
call for sulfur-sulfhydryl repletion and other liver p450 support.
Many nutrient supplements are beneficial and well tolerated, including
dimethylglycine (DMG) and a combination of pyridoxine (vitamin
B6) and magnesium, both of which benefit roughly half of ASD cases.
Vitamins A, B3, C, and folic acid; the minerals calcium and zinc;
cod liver oil; and digestive enzymes, all offer benefit. Secretin,
a triggering factor for digestion, is presently under investigation.
Immune therapies (pentoxifyllin, intravenous immunoglobulin, transfer
factor, and colostrum) benefit selected cases. Long-chain omega-3
fatty acids offer great promise. Current pharmaceuticals fail
to benefit the primary symptoms and can have marked adverse effects.
Individualized, in-depth clinical and laboratory assessments and
integrative parent-physician-scientist cooperation are the keys
to successful ASD management.

Treatment of late onset autism as a consequence
of probable autommune processes related to
chronic bacterial infection.
Matarazzo EB.
Department of Psychiatry, School of Medicine, University of Sao
Paulo, Brazil. eneidam_br@yahoo.com.br
Two cases are described of children who at first developed
normally, but before the age of three developed autistic symptoms
following the reactivation of a chronic oto-rhinolaryngologic
infection. The clinical and laboratory data of the cases support
the aetiological hypothesis of an autoimmune process. Adrenocorticotrophic
hormone (ACTH), prescribed in the first months of the disease,
cured one case. The other patient, who was two years old when
autistic symptoms appeared and was treated only six years later,
showed a partial but definitive improvement with the immunosuppressive
treatment. This report proposes that reactivation of a chronic
bacterial infection be included among the aetiologies of Late
Onset Autism, and demonstrates that, when the aetiological hypothesis
of an autoimmune process based on clinical and laboratory data
is considered, an immunosuppressive treatment, particularly with
ACTH, can be very effective and also safe.

Klinikums der Johann Wolfgang Goethe-Universitat. Boelte@em.uni-frankfurt.de
OBJECTIVE: We describe and critically discuss intervention
methods that have been used to modify autistic behaviors. METHODS:
Early intervention methods, training of social skills, pharmacological
treatment and alternative approaches are reviewed in the light
of the empirical evidence. RESULTS: Autism is a persistent and
phenotypically heterogeneous disorder for which no cure has been
found to date. However, individually composed care and therapies
can lead to remarkable quantitative improvement. CONCLUSIONS:
Further research is needed to evaluate the true impact of psychological
and biological intervention techniques in autistic disorders.
Among other things, the therapy studies carried out up to now
often lack an adequate diagnostic assessment.

The autistic spectrum: subgroups, boundaries,
and treatment.

Center, PO Box 85500, 3508 GA Utrecht, The Netherlands. s.h.n.willemsen@psych.azu.nl
There is consensus about the disorders that comprise the autistic
spectrum, with autistic disorder, Asperger's disorder, and PDD-NOS
as the most typical examples and Rett's disorder and disintegrative
disorder as the other components. Important controversies regarding
the precise definitions of autistic spectrum disorders and the
boundaries between the milder manifestations of those disorders,
particularly PDD-NOS, and non-autistic conditions have not been
and cannot be resolved fully as long as there is no known biologic
cause or consistent biologic or psychological marker. This includes
issues as basic as whether the autistic spectrum is a predominantly
unitary entity or a collection of more or less similar phenotypes
with multiple, varying etiologies. This is why the highest long-term
priority in the area of definite diagnosis is the search for biologic
marker(s) for autism and related autism spectrum disorders [91].
In the absence of a medical test to unequivocally diagnose autism,
definitions of autism and related conditions are based only on
manifestations in overt behavior, with all the unreliability this
entails. In the future, the discovery of biologic correlates,
causes, and pathogenetic pathways will undoubtedly change the
way in which autism is diagnosed and lead to a new nosology [95].
Until that time the definitions in the current versions of the
classification systems should be considered in a state of evolution.
The key problem of the current classification systems is the fact
that the boundaries between the various disorders are fuzzy. Instead
of a categorical approach, a more useful description might be
that of "autistic spectrum disorder," which reflects
the range of severity of symptoms. Such a dimensional understanding
of PDD is useful to clinicians, who may otherwise use nonspecific
terms to avoid the categorical diagnosis of autism [31]. Rutter
and Schopler [96] argued for separate clinical and research schemes
because clinical and research needs are different. For research
purposes it is desirable to have as much direct comparability
across studies as possible. The focus is on a high degree of homogeneity
within diagnostic groupings. A price must be paid for this detailed
specification, and the main cost lies in the proportion of cases
left undiagnosed. For example, there may be good scientific reasons
for a narrowly defined categorical diagnosis that includes only
individuals who definitely and clearly have a specifically defined
condition and excludes individuals who may have the condition.
For clinicians and educators, classification helps guide the selection
of treatments for an individual. From this point of view, broader
diagnostic concepts may be most appropriate [95].

A retrospective open trial of adjunctive donepezil
in children and adolescents with autistic disorder.
Hardan AY, Handen BL.

University of Pittsburgh School of Medicine, Pittsburgh, Pennsylvania
15213, USA. hardanay@msx.upmc.edu
In light of the recently reported neuropathologic and neurochemical
abnormalities of the cholinergic pathways in autism, donepezil,
a cholinesterase inhibitor, is a potentially useful agent in the
treatment of cognitive and behavioral symptoms observed in this
disorder. A retrospective pilot study was conducted to determine
whether donepezil is effective in the treatment of children and
adolescents with autism. Eight patients (mean age = 11.0 4.1 years;
range 7-19 years) who met Diagnostic and Statistical Manual of
Mental Disorders (4th edition) criteria for autistic disorder
were openly treated with donepezil. All patients were on concomitant
psychoactive medications. Four of these patients (50%) demonstrated
significant improvement as assessed by the Aberrant Behavior Checklist
and the Clinical Global Impression Scale. Decreases in the Irritability
and Hyperactivity subscales were observed, but no changes in the
Inappropriate Speech, Lethargy, and Stereotypies subscales were
noted. Limited and transient side effects were reported, with
one patient experiencing gastrointestinal disturbances and another
reporting mild irritability. Double-blind, placebo-controlled
investigations are needed to provide further evidence of the potential
benefits of donepezil to patients with autistic disorder.

Fluoxetine response in children with autistic
spectrum disorders: correlation with familial major affective
disorder and intellectual achievement.
DeLong GR, Ritch CR, Burch S.
Department of Pediatrics, Duke University Medical Center, Durham,
NC 27710, USA. Delon006@mc.duke.edu
One hundred and twenty-nine children, 2 to 8 years old, with
idiopathic autistic spectrum disorder diagnosed by standard instruments
(Childhood Austim Ratings Scale and Autism Diagnostic Observation
Schedule) were treated with fluoxetine (0.15 to 0.5mg/kg) for
5 to 76 months (mean 32 to 36 months), with discontinuation trials.
Response criteria are described. Family histories were obtained
using the family history method in repeated interviews. Fluoxetine
response, family history of major affective disorder, and unusual
intellectual achievement, pretreatment language, and hyperlexia
were used to define a coherent subgroup of autistic spectrum disorder.
Statistical analyses were post hoc. Of the children, 22 (17%)
had an excellent response, 67 (52%) good, and 40 (31%) fair/poor.
Treatment age did not correlate with response. Fluoxetine response
correlated robustly with familial major affective disorder and
unusual intellectual achievement, and with hyperlexia in the child.
Family history of bipolar disorder and of unusual intellectual
achievement correlated strongly. Five children developed bipolar
disorder during follow-up. Fluoxetine response, family history
of major affective disorder (especially bipolar), unusual achievement,
and hyperlexia in the children appear to define a homogeneous
autistic subgroup. Bipolar disorder, unusual intellectual achievement,
and autistic spectrum disorders cluster strongly in families and
may share genetic determinants.

A randomized, double-blind, placebo-controlled
trial of porcine versus synthetic secretin for reducing symptoms
of autism.

R, Abbott RD, Dawson G.
Department of Psychiatry and Behavioral Science, University of
Washington, Seattle, WA 98195, USA.
OBJECTIVE: To compare the effects of a single dose of biologic
and synthetic porcine secretin to placebo on a variety of autism
symptoms. METHOD: Eighty-five children with autism without other
medical conditions and not taking other psychotropic medications
participated (ages between 3 and 12 years, mean IQ = 55). Children
were grouped into trios matched by age and communication level
and then randomly assigned to one of three treatment groups: biologic
secretin (2 CU/kg), synthetic secretin (0.4 microg/kg), and placebo.
Measures collected 1 week before and 4 weeks after infusion included
autism symptoms, language skills, and problem behaviors, gathered
from parents, teachers, and investigators, who were all blind
to treatment. Two-factor, repeated-measures analyses of variance
(3 treatment levels by 2 repeated measures, pre- and postinfusion)
were used to examine efficacy. RESULTS: Direct observation measures
did not show change over time related to secretin. Parent reports
showed an overall reduction of symptom severity for all treatment
groups, including the placebo group. One teacher-report measure
showed decreases in autism symptoms in the placebo and synthetic
secretin groups. CONCLUSIONS: No evidence that either biologic
or synthetic secretin provided amelioration of symptoms beyond
placebo was observed. This held true when children with and without
gastrointestinal problems were examined separately.

Risperidone in the treatment of autistic Thai
children under 4 years of age.
Boon-Yasidhi V, Tarugsa J, Suwanwattana C, Soising L.
Department of Pediatrics, Faculty of Medicine Siriraj Hospital,
Mahidol University, Bangkok, Thailand.
The authors report five cases of very young children with autistic
disorder, aged 2.1-3.7 years, treated with risperidone, as part
of the comprehensive intervention. Treatment with risperidone
0.25-0.5 mg per day was associated with clinically meaningful
decreases in problem behaviors including hyperactivity, irritability,
and aggressiveness. There were also improvements in social relatedness
and cooperation with developmental treatment. All of the children
tolerated the medication well and experienced no untoward effects.
The efficacy of risperidone in the treatment of very young children
with autistic disorder reported here is consistent with findings
in the limited number of cases previously reported in the literature.
Controlled studies are needed to confirm the efficacy and safety
of risperidone in the treatment of these children.

Secretin as a neuropeptide.
Ng SS, Yung WH, Chow BK.
Department of Zoology, University of Hong Kong, Hong Kong, PRC.
The role of secretin as a classical hormone in the gastrointestinal
system is well-established. The recent debate on the use of secretin
as a potential therapeutic treatment for autistic patients urges
a better understanding of the neuroactive functions of secretin.
Indeed, there is an increasing body of evidence pointing to the
direction that, in addition to other peptides in the secretin/glucagon
superfamily, secretin is also a neuropeptide. The purpose of this
review is to discuss the recent data for supporting the neurocrine
roles of secretin in rodents. By in situ hybridization and immunostaining,
secretin was found to be expressed in distinct neuronal populations
within the cerebellum and cerebral cortex, whereas the receptor
transcript was found throughout the brain. In the rat cerebellum,
secretin functions as a retrograde messenger to facilitate GABA
transmission, indicating that it can modulate motor and other
functions. In summary, the recent data support strongly the neuropeptide
role of secretin, although the secretin-autism link remains to
be clarified in the future.

Effects of single and repeated shock on perceived
pain and startle response in healthy volunteers.
Duker PC, Douwenga H, Joosten S, Franken T.
Psychology Laboratory, University of Nijmegen and Plurijn Foundation,
Netherlands. p.duker@ped.kun.nl
Contingent shock (CS) has been used in a number of studies
to suppress health-threatening self-injurious behavior of individuals
with mental retardation and autism. As sustained suppression is
an issue of concern, research into procedural variables of CS
is needed. In this study, clinical evidence was used to infer
a variable that might be of relevance for the application of clinical
contingent shock, that is, to assess the effect of single versus
repeated shock at a specific location on the body. With pain intensity
and startle response as dependent variables, shocks were administered
to 48 healthy volunteers. Electric shocks were identical to those
that used in clinical practice. The second shock in succession
to the same location of the body produced higher pain intensity
ratings than the first shock and that the third shock in succession
to the same location of the body produced higher pain intensity
ratings than the second shock in succession. Startle responses,
however, failed to be affected in this direction. The latter result
is consistent with a previous study. Our data suggest that repeated
shock to the same location is likely to be more effective to establish
suppression than repeated shock to different locations.

Engeland H.
University Medical Center Utrecht, Department of Child and Adolescent
Psychiatry, The Netherlands. C.kemner@psych.azu.nl
The effects of olanzapine on the symptomatology of children
with pervasive developmental disorder with emphasis on problems
of communication and the safety of the drug were investigated
in a 3-month open-label, open-dosage study. Participating in the
study were 25 children age 6 to 16 years with a diagnosis of either
autistic disorder or pervasive developmental disorder not otherwise
specified. Psychometric measures included the Clinical Global
Impression of Severity/Improvement, the Aberrant Behavior Checklist,
and the TARGET (a checklist of five target symptoms). Communication
skills were assessed during behavioral analysis of a playroom
session. Safety measures included clinical chemistry variables,
electrocardiography, the SimpsonAngus Neurological Rating Scale,
the Barnes Akathisia Scale, and vital signs. Twenty-three children
completed the study and showed significant improvement on three
subscales of the Aberrant Behavior Checklist (Irritability, Hyperactivity,
and Excessive Speech) and the TARGET. The final mean dose was
10.7 mg/day. Several aspects of communication were also improved
after olanzapine treatment. However, only three children were
considered responders in terms of the Clinical Global Impression
of Severity/Improvement scores. The most important adverse events
were weight gain, increased appetite, and loss of strength. Three
children showed extrapyramidal symptoms that disappeared after
the dose was lowered. Thus, while olanzapine was a relatively
safe medication in children, its clinical relevance in children
with pervasive developmental disorder may be limited.

Risperidone: a potential treatment for autism.
Posey DJ, McDougle CJ.
Riley Hospital for Children, Indianapolis, IN 46202, USA. dposey@iupui.edu
Autistic disorder (autism) is a neuropsychiatric syndrome characterized
by marked deficits in reciprocal social relatedness, communication
impairment and a narrow range of interests and/or repetitive behaviors.
Autism is frequently associated with, but distinct from, mental
retardation. It is classified as a subtype of pervasive developmental
disorder (PDD) along with 'PDD not otherwise specified' (NOS)
and Asperger's disorder. These disorders have in common marked
impairments in social relatedness. Individuals with autism may
also have other symptoms that become the primary focus of psychiatric
treatment. These associated symptoms include aggression, self-injury,
irritability and anxiety.

Live virus vaccination near a pregnancy: flawed

tlautstudy@aol.com
Vaccination of women with live virus vaccines around conception
has always been contraindicated by the Center for Disease Control
and Prevention (CDC) and the vaccine manufacturer because of potential
risks to the fetus. Nevertheless this dangerous practice occurs
and is associated with maternal health problems and a very high
incidence of early-onset autism in the children.Postpartum vaccination
with live virus vaccines has been recommended by the CDC, and
described as 'convenient' by the vaccine manufacturer. This 'routine
practice' may lead to health and is also associated with many
health and obstetrical problems in the recipient, and is frequently
associated with autism in both current and future children. Re-vaccination
often fails to produce immunity, the very reason for which it
was recommended.

Treatment of autism spectrum children with thiamine
tetrahydrofurfuryl disulfide: a pilot study.
Lonsdale D, Shamberger RJ, Audhya T.
Preventive Medicine Group, 24700 Center Ridge Road, Westlake,
OH 44145, USA. dlonsdale@pol.net
OBJECTIVES: In a Pilot Study, the clinical and biochemical
effects of thiamine tetrahydrofurfuryl disulfide (TTFD) on autistic
spectrum children were investigated. SUBJECTS AND METHODS: Ten
children were studied. Diagnosis was confirmed through the use
of form E2, a computer assessed symptom score. For practical reasons,
TTFD was administered twice daily for two months in the form of
rectal suppositories, each containing 50 mg of TTFD. Symptomatic
responses were determined through the use of the computer assessed
Autism Treatment Evaluation Checklist (ATEC) forms. The erythrocyte
transketolase (TKA) and thiamine pyrophosphate effect (TPPE),
were measured at outset and on completion of the study to document
intracellular thiamine deficiency. Urines from patients were examined
at outset, after 30 days and after 60 days of treatment and the
concentrations of SH-reactive metals, total protein, sulfate,
sulfite, thiosulfate and thiocyanate were determined. The concentrations
of metals in hair were also determined. RESULTS: At the beginning
of the study thiamine deficiency was observed in 3 out of the
10 patients. Out of 10 patients, 6 had initial urine samples containing
arsenic in greater concentration than healthy controls. Traces
of mercury were seen in urines from all of these autistic children.
Following administration of TTFD an increase in cadmium was seen
in 2 children and in lead in one child. Nickel was increased in
the urine of one patient during treatment. Sulfur metabolites
in urine did not differ from those measured in healthy children.
CONCLUSIONS: Thiamine tetrahydrofurfuryl disulfide appears to
have a beneficial clinical effect on some autistic children, since
8 of the 10 children improved clinically. We obtained evidence
of an association of this increasingly occurring disease with
presence of urinary SH-reactive metals, arsenic in particular.

Impaired social interaction, communication and imaginative
skills characterize autistic syndromes. In these syndromes urinary
peptide abnormalities, derived from gluten, gliadin, and casein,
are reported. They reflect processes with opioid effect. The aim
of this single blind study was to evaluate effect of gluten and
casein-free diet for children with autistic syndromes and urinary
peptide abnormalities. A randomly selected diet and control group
with 10 children in each group participated. Observations and
tests were done before and after a period of 1 year. The development
for the group of children on diet was significantly better than
for the controls.

Case series: use of ziprasidone for maladaptive
symptoms in youths with autism.

Department of Psychiatry, Indiana University School of Medicine,
Indianapolis 46202-4800, USA.
OBJECTIVE: To conduct a preliminary evaluation of the safety
and effectiveness of ziprasidone in children, adolescents, and
young adults with autism. METHOD: Twelve patients (mean age SD,
11.62 4.38 years; range, 8-20 years) with DSM-IV-defined autism
(n = 9) or pervasive developmental disorder not otherwise specified
(n = 3) received open-label treatment with ziprasidone (mean daily
dose, 59.23 34.76 mg; range, 20-120 mg) for at least 6 weeks (mean
duration, 14.15 8.29 weeks; range, 6-30 weeks). RESULTS: Six (50%)
of the 12 patients were considered responders based on a Clinical
Global Impression Scale rating of "much improved" or
"very much improved." Transient sedation was the most
common side effect. No cardiovascular side effects, including
chest pain, tachycardia, palpitations, dizziness, or syncope,
were observed or reported.The mean change in body weight for the
group was -5.83 12.52 lb (range, -35 to lb). Five patients lost
weight, five had no change, one gained weight, and one had no
follow-up weight obtained beyond the baseline measurement. CONCLUSIONS:
Ziprasidone appears to have the potential for improving symptoms
of aggression, agitation, and irritability in children, adolescents,
and young adults with autism. Significant weight gain was not
observed in this short-term trial. Double-blind, placebo-controlled
studies are needed to substantiate these preliminary findings.

Use of a GABA-transaminase agonist for treatment
of infantile autism.
Cohen BI.
ED Laboratories, S. Hackensack, New Jersey 07606, USA. EDS@Pipeline.com
This paper describes the use of a GABA-transaminase agonist
for the treatment of infantile autism. An approximate one third
reduction of GABA and ammonia levels for an autistic patient with
noticeable improvement of verbal/language skills and a reduction
of repetitious ritualistic self-stimulatory behavior (stimming)
was observed. A reduction of the plasma GABA (by administrating
a GABA-T agonist, Imipramine) probably results in more axon(s)-to-oligodendrocyte
signaling in the corpus callosum and it is postulated that this
could result in a reduction of the autistic features for the patient.

Gluten and casein free diets in autism: a study
of the effects on food choice and nutrition.
Cornish E.
Community Nutrition Service, South Derbyshire Community Health
NHS Trust, Dar es Salaam, Tanzania.
BACKGROUND: There is growing interest in possible dietary involvement
in the aetiology and treatment of Autistic Spectrum Disorders
(ASD). Research has focused on the physiological and behavioural
effects of dietary change but has not examined the effect of exclusion
diets on nutritional intake. AIMS: The aim of this study was to
examine whether the removal of major dietary staples placed children
with autism at risk of nutrient deficiency and compares their
food choice with ASD children not following gluten and/or casein
free diets. METHODS: A postal questionnaire was sent to parents
of children aged 3-16 years, diagnosed with ASD belonging to the
National Autistic Society in Leicestershire and southern Derbyshire.
Detailed dietary information and a 3-day food diary were collected.
The sample size was small: those using gluten/casein free diets
(n = 8) and those not following diet (n = 29). RESULTS: Nutrient
intakes fell below the Lower Reference Nutrient Intake (LRNI)
in 12 children (32%) for zinc, calcium, iron, vitamin A, vitamin
B12 and riboflavin in the nondiet group and four children (50%)
for zinc and calcium in the diet group. Fruit and vegetable intakes
were higher and cereal, bread and potato consumption were lower
in those children using gluten and/or casein free diets. CONCLUSION:
No significant differences in the energy, protein and micronutrient
intakes were found between the two groups of children. A longitudinal
prospective study is suggested to examine whether differences
in food choice are the result of dietary intervention or the prerequisite
for the successful application of diet in this special group of
children.

78712, USA.
We assessed evidence of the effects of secretin on behavior
in individuals with autistic disorder. Articles were obtained
through a MEDLINE search of the English-language literature from
January 1966-November 2001; all investigations and case reports
on the topic were included. Press releases obtained from the World
Wide Web also were included. Secretin, a gastrointestinal hormone,
is suggested to improve autistic symptoms, particularly social
function and communication. Two formulations, porcine and synthetic
human secretin, were evaluated in humans. A small body of literature
and popular belief in autistic disorder communities supported
the agent's efficacy. A number of controlled clinical trials did
not show improvement in autistic symptoms with secretin compared
with placebo, possibly indicating no role for the drug in autistic
disorder.

Multiple doses of secretin in the treatment of
autism: a controlled study.

Centre for Child and Adolescent Psychiatry, University Hospital,
Oslo, Norway. eili.sponheim@psykiatri.uio.no
Dramatic effects on autistic behaviour after repeated injections
of the gastrointestinal hormone secretin have been referred in
a number of case reports. In the absence of curative and effective
treatments for this disabling condition, this information has
created new hope among parents. Although controlled studies on
the effect of mainly one single dose have not documented any effect,
many children still continue to receive secretin. Six children
enrolled in a double-blind, placebo-controlled crossover study
in which each child was its own control. Human synthetic secretin,
mean dose 3.4 clinical units, and placebo were administered intravenously
in randomized order every 4th wk, on three occasions each. The
measurement instruments were the visual analogue scale (VAS) and
the aberrant behaviour checklist (ABC). Statistically significant
differences were found for placebo in 3 out of 6 children and
for secretin in one child, using parental ratings only (VAS scores).
Differences were small and lacked clinical significance, which
was in accordance with the overall impression of the parents and
teachers and visual inspection of graphs. Conclusion: In this
placebo-controlled study, multiple doses of secretin did not produce
any symptomatic improvement.

USA. TCarey@mc.edu
Secretin has been proposed as a treatment alternative for autistic
spectrum disorders, but empirical support is lacking. A double-blind
placebo-controlled study examined the effect of a single dose
of synthetic human secretin on aberrant behavior. Parent and teacher
data from the Aberrant Behavior Checklist for eight male children
were analyzed for reliable change in a clinical replication series.
By parent and teacher report, the majority of change occurred
either on the placebo trial or reflected deterioration subsequent
to secretin infusion. Repeated-measures multivariate analysis
of variance results were similar. Results are consistent with
other studies, suggesting that secretin may not be an effective
treatment option.

diarrhea. To determine the efficacy of secretin, we completed
a double-blind, placebo-controlled, crossover (3 weeks) study
in children with autism/PDD and various GI conditions using a
single dose of intravenous porcine secretin. Children with chronic,
active diarrhea showed a reduction in aberrant behaviors when
treated with the secretin but not when treated with the placebo.
Children with no GI problems are unaffected by either secretin
or placebo. The improvement seen with secretin in children with
autism/PDD and chronic diarrhea suggests that there may be a subtype
of children with autism/PDD who respond to secretin.

Autism is an early developmental disorder. It leads to severe
and durable disturbances. Given this problem, no treatment can
be excluded a priori. Thus, many approaches are used to deal with
autistic disorders. In France, pharmacological treatments are,
for instance, largely and mostly used in adults. In the USA, these
treatments concern 50% of persons with autism of any age. Nevertheless,
they are rarely based on controlled studies. At the present, however,
prescriptions and expected effects appear to be hard to localize.
Furthermore, only few controlled studies validate their use. Aim
- We offer a review of studies about medical treatments used in
adolescents and adults with autism. They are classified in 3 categories:
the first (category I) includes drugs used for their neurochemical
effects focusing on autistic signs. The second (category II) covers
drugs used for treatment of behavioural disorders frequently associated
with autism. The third (category III) corresponds to a wide range
of drugs or vitamins for wich only few case studies exist reporting
irregular positive effects. The main hypothesis of this review
is that autism involves a dysfunction of the neuromediation systems.
This hypothesis opens new perspectives in the research of medical
treatments in autism by focusing on molecules, which are supposed
to have an effect on neuromediation systems. Method - Our review
is based on studies, which have been published during the past
twenty years. For many studies, data are limited to adolescents
and adults. So we expanded our review to data available in children.
The data bases that we have used are medline and psyclit. Keywords
have been chosen according to: pharmacological considerations
(psychotropic, psychoactive drugs, psychopharmacology) and clinical
symptoms (autism, automutilations, aggressive behavior, and hyperactivity).
Hypothesis of a dysfunction in the neuromediation systems in autism
- Many studies exist about biochemical abnormalities in autism.
As in schizophrenia and mental retardation, dysfunctions of the
neuromediation systems are considered to be etiological factors.
In 30% of people with autism the most regular dysfunction is the
increase of serotonine. This led to the serotoninergic hypothesis
in autism and to the use of active drugs in the serotonine system.
However, the presence of other neurometabolic abnormalities also
motivates the use of drugs, supposed to be active in other neuromediation
systems. Pharmacological treatments in autism - Category I section
sign 1 Active drugs in the dopamine system. Haloperidol (Dopamine
antagonist): The effects of this molecule have been broadly studied
in autism. Results indicate high efficiency in some symptoms of
autism (lack in social behaviour, stereotypical behaviour) and
in behavioural impairments that may be associated with autism
(aggressive behaviour, hyperactivity). Its side effects, particulary
the risk of late dyskinesy, make atypical antipsychotics preferable
because of their lower risks. Risperidone (Dopamine and serotonine
antagonist): Among several studies only few have been controlled.
They indicate that Risperidone has positive effects on the behaviour
and is quite well tolerated. section sign 2 Active drugs in the
serotonine system. Clomipramine: after promising results, the
medium-term efficiency has decreased and severe side effects have
limited its use. Fluvoxamine, Fluoxetine, Sertraline (Specific
serotonine drugs): Their efficiency has been mainly tested through
open studies and their results are contrasted. In some cases,
social behaviours have improved and aggressiveness and stereotyped
behaviours have decreased. Fenfluramine: At present, this drug
is removed from the market. Yet, some studies have suggested that
it improves behavioural disturbances as well as performances in
autism. section sign 3 Active drugs in the opiate system. Naltrexone:
Several controlled studies have indicated an improvement in social
and aggressive behaviours. Nevertheless, these studies have used
small size sample and have not been replicated. Category II. This
category correspond to drugs supposed to be active on neurochemical
disturbances found in autism but their target symptoms are not
autism specific signs as defined by the ICD 10. Buspirone: This
serotonine agonist may have a good impact on emotional disorders
and sleeping confusions. Methylphenidate: Most of the current
studies about this noradrenergic drug concern children. The results
are variable. Paradoxical effects may exist in children with severe
mental retardation. Propanolol: Some isolated studies habe reported
its efficiency on behavioural disturbances. Clonidine: This adrenergic
drug treats efficiently some cases of aggressive behaviour and
hyperactivity. Category III. This category contains a wide range
of drugs, vitamins or method used in autism after sporadic observations
of their positive effects. Secretine: An important improvement
has been reported in isolated cases. However, controlled studies
in children do not confirm these results. Vitamines B6, B12 and
Magnesium: An improvement in socialization and in behavioural
disorders have been reported in some cases, but these results
are not yet confirmed. Lithium, Carbamazepine, Valproate: Results
of some case studies have found it to be efficient in cyclic disorders.
Gluten and casein free diet: An improvement of social behaviour
have been reported by some parents after these diets. No controlled
study has validated this observation. Conclusion - There is no
consensus on the use of psychopharmacological treatments in autism.
Although there exist many clinical observations, only few controlled
studies have validated the efficiency and safety of these treatments.
At the present time and until having sufficient studies, drugs
are generally limited to severe disorders, for which usual psycho-educational
approaches are insufficient.

Parent-managed behavioral interventions for young children
with autism are under-researched. We analysed data from 66 children
served by 25 different early intervention consultants. After a
mean of 31.6 months of intervention, IQ scores had not changed
(N = 22). Vineland adaptive behavior scores had increased significantly
by 8.9 points (N = 21). No children aged >72 months attained
normal functioning, i.e., IQ > 85 and unassisted mainstream
school placement (N = 42). Progress for 60 children across 12
months was found for mental age (5.4 months), adaptive behavior
(9.7 months), and language (5.1 months). The interventions did
not reproduce results from clinic-based professionally directed
programs. The effectiveness of the parent-managed intervention
model as it has developed and the adequacy of professional services
in that model are discussed.

Enzyme-based therapy for autism spectrum disordersis
it worth another look?

Autism is a developmental disease usually manifesting within
the first three years of life. To date, no causative agent has
been found. Similarly, treatment options have been limited. Of
the treatment options available, a number of them have been nutritionally
based in an attempt to address one or more of the theories regarding
the etiology of the disease. An example would be enzyme therapy
for the digestion of purported offending neuroactive peptides
collectively known as exorphins. This paper discusses the exorphin
theory of autism and subsequent treatment with dietary enzyme
therapy. Novel data are presented in support of the theory that
enzymes play a critical role in autism. Forty-six patients between
the ages of 5 and 31 were selected for inclusion in the study
based on a diagnosis placing them in the category of the autism
spectrum disorders (ASD). The diets were supplemented with a novel
dietary enzyme formulation, ENZYMAID, for a period of 12 weeks.
Progress was tracked according to the Symptom Outcome Survey (SOS)
(1) form method of symptom charting and presented in a table for
further analysis. The novel enzyme formula, ENZYMAID, beneficially
and safely affected all 13 of the parameters measured. Improvements
ranged from 50-90%, depending on the parameter measured. Enzyme
therapy to treat ASD may indeed a viable option in treatment protocols.
These results indicate that further controlled studies are warranted.

Autism is a collection of behavioral symptoms characterized
by dysfunction in social interaction and communication in affected
children. It is typically associated with restrictive, repetitive,
and stereotypic behavior and manifests within the first 3 years
of life. The cause of this disorder is not known. Over the past
decade, a significant upswing in research has occurred to examine
the biologic basis of autism. Recent clinical studies have revealed
a high prevalence of gastrointestinal symptoms, inflammation,
and dysfunction in children with autism. Mild to moderate degrees
of inflammation were found in both the upper and lower intestinal
tract. In addition, decreased sulfation capacity of the liver,
pathologic intestinal permeability, increased secretory response
to intravenous secretin injection, and decreased digestive enzyme
activities were reported in many children with autism. Treatment
of digestive problems appears to have positive effects on autistic
behavior. These new observations represent only a piece of the
unsolved autism "puzzle" and should stimulate more research
into the brain-gut connection.
