Abstract
Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by diverse behavioral symptoms such as repetitive behaviors, social deficits, anxiety, hyperactivity, and irritability. Despite their increasing incidence, the specific pathological mechanisms of ASD are still unknown, and the degree and types of symptoms that vary from patient to patient make it difficult to develop drugs that target the core symptoms of ASD. Although various atypical antipsychotics and antidepressants have been applied to regulate ASD symptoms, these drugs can only alleviate the symptoms and do not target the major causes. Therefore, development of novel drugs targeting factors directly related to the onset of ASD is required. Among the various factors related to the onset of ASD, several chemical modulators to treat ASD, focused on serotonin (5-hydroxytryptamine, 5-HT) and glutamate receptors, microbial metabolites, and inflammatory cytokines, are explored in this study. In particular, we focus on the chemical drugs that have improved various aspects of ASD symptoms in animal models and in clinical trials for various ages of patients with ASD.

Abstract
BACKGROUND Antipsychotic medication is a commonly prescribed drug class in individuals with autism spectrum disorder (ASD). However, the safety of these agents has not been fully assessed. OBJECTIVE Our objective was to investigate the safety and tolerability profile of antipsychotics in individuals with ASD. METHODS The Cochrane Library, MEDLINE, Embase and PsycINFO databases were searched up to January 2018. We included studies that reported adverse events (AEs) in participants with ASD taking first- or second-generation antipsychotic medication. The studies included in the analysis were randomized controlled trials (RCTs) and observational studies that were comparative or noncomparative and published as full text in the English language. The primary outcome of this review was AEs of any severity reported with antipsychotic use at any dose. Meta-analysis was performed on studies with child and adolescent participants to estimate the pooled prevalence of the overall AEs and the relative risk (RR) of AEs associated with antipsychotic use using a random-effects model. The Cochrane Collaboration tool and the modified Newcastle-Ottawa Scale (NOS) were used to assess the risk of bias of the included RCTs and observational studies, respectively. RESULTS In total, 54 citations fulfilled the inclusion criteria, of which 40 were RCTs and 14 were observational studies; eight RCTs were included in the meta-analysis to estimate the RR of AEs associated with antipsychotic use and seven observational studies were included to estimate the pooled prevalence of AEs. The RR of AEs with antipsychotic treatment was 22% higher than with placebo (RR 1.22; 95% confidence interval [CI] 1.11-1.34; I2 = 30.6%; p = 0.184). The estimated pooled prevalence of AEs was 50.5% (95% CI 33-67). The most commonly reported AEs were increased appetite and weight gain, which were associated with discontinuation in many participants. CONCLUSION Antipsychotic-related AEs were common among patients with ASD. Further studies to investigate the implications of antipsychotic-related AEs on health and medication adherence are warranted. PROSPERO registration number: (CRD42018083632).

Abstract
AIM In an attempt to clarify the debate surrounding the diagnostic validity of childhood disintegrative disorder (CDD), we systematically reviewed its characteristics and compared it with autism spectrum disorder (ASD). METHOD Four databases were searched (PubMed, PsycINFO, Embase, and Web of Science). Included articles had participants with CDD, as defined by symptoms present in the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and the International Classification of Diseases, 10th Revision. Comparison groups were those with ASD and ASD with regression. Case studies were excluded. RESULTS Twenty articles, comprising 96 participants with CDD (80 males, 16 females), were included. Most studies were cross-sectional. The prevalence of CDD was 1.1 to 9.2 per 100 000, with a mean age at regression of 3 years 2 months (SD 1y 1mo), with a range of 2 years to 7 years. In addition to core CDD symptoms, most had intellectual impairment, anxiety, challenging behaviours, and regressed in toileting skills. Participants with CDD and ASD shared core diagnostic and extra-diagnostic features. However, participants with CDD seemed to have more severe symptoms and a different symptom profile, including apparently typical development before regression, faster regression, more affective symptoms, and more global developmental deficit. Possible genetic and autoimmune neurobiological mechanisms were identified. INTERPRETATION There is limited high-quality evidence describing the aetiology and outcomes of CDD. However, given the qualitative and prognostic differences between ASD and CDD, we recommend that future diagnostic criteria should distinguish late-onset regression.

Abstract
Background Although risperidone is increasingly used for behavioral indications in children, the associated adverse events (AEs) are not well defined in this population. Objective We determined the incidence of and risk factors for AEs among children treated with risperidone at our institution, an academic medical center with inpatient, outpatient, generalist, and specialist pediatric care. Methods The study included children aged ≤ 18 years with ≥ 4 weeks of risperidone exposure. Data were obtained using de-identified electronic health records. AEs were defined as any untoward event attributed to risperidone reported by the patient, parent/guardian, or physician or detected following a laboratory investigation. Associations between AEs and clinical variables were determined using univariate and multivariate analyses. Results The study cohort included 371 individuals (median age 7.8 years [interquartile range 5.9–10.2]; 271 [73.0%] male). The two most common primary diagnoses were attention-deficit/hyperactivity disorder (160 [43.1%]) and autism (102 [27.5%]). The most frequent indications for risperidone were aggression (166 [44.7%]) and behavioral problems (114 [30.7%]). Altogether, 110 (29.6%) individuals had 156 AEs. Weight gain (32 [20.5%]) and extrapyramidal symptoms (23 [14.7%]) were the most common AEs. Aggression, irritability, and self-injurious behavior were positively associated with AEs, and concomitant analgesics and antibiotics were negatively associated. In multivariate analysis, associations remained significant for self-injurious behavior (adjusted odds ratio [aOR] 3.1; 95% confidence interval [CI] 1.7–5.4) and concomitant antibiotics (aOR 0.2; 95% CI 0.1–0.9). Conclusions Nearly one in three children treated with risperidone for ≥ 1 month experienced one or more AEs. Particular vigilance is warranted for children with self-injurious behavior.

Abstract
Repetitive behaviors are seemingly purposeless patterns of behavior that vary little in form and are characteristic of many neurodevelopmental, psychiatric, and neurologic disorders. Our work has identified an association between hypofunctioning of the indirect basal ganglia pathway and the expression of repetitive behavior in the deer mouse model. In this study, we targeted indirect pathway cells of the striatum with single drugs and drug combinations that bind to dopamine D2, adenosine A2A, and glutamate mGlu5 receptors. These receptors function both individually and as receptor heteromers. We found that only the triple drug cocktail (L-741,626+CGS21680+CDPPB) that was designed to increase striatal indirect basal ganglia pathway cell function reduced repetitive behavior in adult male deer mice. No single drug or double drug combinations were effective at selectively reducing repetitive behavior. We found this triple drug cocktail reduced repetitive behavior in both short-acting and long-acting formulations and was effective throughout 7 days of daily administration. Conversely, another triple drug cocktail (quinpirole+SCH58261+MTEP) that was designed to further reduce striatal indirect basal ganglia pathway cell function caused a significant increase in repetitive behavior. Significant and behaviorally selective effects on repetitive behavior were only achieved with the triple drug cocktails that included doses of L-741,626 and quinpirole that have off-target effects (e.g., dopamine D3 receptors). These data further a role for decreased indirect basal ganglia pathway activation in repetitive behavior and suggest that targeting these receptors and/or heteromeric complexes on the indirect pathway neurons of the striatum may offer pharmacotherapeutic benefit for individuals with repetitive behavior disorders.

Abstract
This paper reviews the evidence base supporting the use of pharmacological treatments for child and adolescent psychiatric disorders. Recent advances in knowledge are highlighted, with some of the controversies. New evidence supports a role for selective serotonin reuptake inhibitors in the treatment of anxiety disorders and obsessive–compulsive disorder. Educational and behavioural approaches remain the mainstay of treatment for children and adolescents with autism, but there is evidence that adjunctive medication may be effective. Atypical antipsychotics have been investigated in the treatment of Tourette syndrome and early-onset schizophrenia. Many questions remain unanswered and further research is needed in all areas of paediatric psychopharmacology.

Abstract
Clinicians in the field of autism are increasingly identifying individuals with Asperger syndrome. Individual and family therapy for individuals with this condition has received little attention in the literature. This article presents three case examples of individual and family therapy with male adolescents diagnosed with Asperger syndrome. Common presenting issues and treatment interventions are summarized that may apply to others diagnosed with this condition.

Abstract
Computational modeling has been useful for understanding processes of encoding and consolidation in cortical structures. In particular, this work suggests a role of neuromodulators in setting dynamics for consolidation processes during different stages of waking and sleep. Because autistic individuals show symptoms of a cognitive nature coupled with a high prevalence of comorbid conditions such as epileptiform discharge during sleep and sleep disorders, it is possible that autism could involve a breakdown in consolidation processes, which are essential to build effective cognitive representations of the environment on the basis of individual experiences. In this article, theories of consolidation during different stages of waking and sleep and the role of different neuromodulators in these consolidation processes are reviewed in conjunction with different features of autism, which may be understood in the context of these theories.

Abstract
The objective of this study was to assess the tolerability and efficacy of pregnenolone in reducing irritability in adults with autism spectrum disorder (ASD). This was a pilot, open-label, 12-week trial that included twelve subjects with a mean age of 22.5 ± 5.8 years. Two participants dropped out of the study due to reasons unrelated to adverse effects. Pregnenolone yielded a statistically significant improvement in the primary measure, Aberrant Behavior Checklist (ABC)-Irritability [from 17.4 ± 7.4 at baseline to 11.2 ± 7.0 at 12 weeks (p = 0.028)]. Secondary measures were not statistically significant with the exception of ABC-lethargy (p = 0.046) and total Short Sensory Profile score (p = 0.009). No significant vital sign changes occurred during this study. Pregnenolone was not associated with any severe side effects. Single episodes of tiredness, diarrhea and depressive affect that could be related to pregnenolone were reported. Overall, pregnenolone was modestly effective and well-tolerated in individuals with ASD.

Abstract
INTRODUCTION Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is often accompanied by psychiatric comorbidity. Although there is no medication currently available to treat the core symptoms of ASD, risperidone was the first drug to be approved for use in ASD and is still the best established psychopharmacological option for the treatment of irritability and behavioral problems in ASD. AREAS COVERED This article gives an overview of the pharmacokinetic profile of risperidone and a comprehensive review of treatment studies regarding the use of risperidone in ASD. EXPERT OPINION Ample evidence supports the short-term use of risperidone for treating irritability and behavioral problems in ASD. Risperidone also shows promise in treating symptoms often associated with ASD, such as stereotypical behavior, social difficulties, hyperactivity and cognitive problems. However, several adverse effects have been identified; most are mild or moderate and well manageable, but weight gain and metabolic changes are a considerable concern. Therefore, risperidone should in our view be seen as 'a last resort', only justified for the short-term treatment of serious behavioral problems, which have failed to respond sufficiently to behavioral interventions. Future studies should investigate long-term effects of risperidone and factors that facilitate individual risk-benefit analyses before treatment.

Abstract
We report several cases in which patients with autistic disorder with mental retardation who received risperidone experienced urinary incontinence. We retrospectively investigated the medical records of patients housed in facilities for patients with autistic disorder with mental retardation. Those who had undergone a medical examination at a hospital in Tokyo from April 1999 to March 2009 were included in the study.Retrospective data were gathered including age, sex, IQ, birth weight, dosage of risperidone, urinary density, as well as existence of urinary and fecal incontinence. We divided the participants into those who did and did not experience urinary incontinence after taking risperidone and compared the 2 groups. Risperidone had been prescribed to 35 patients. In spite of the fact that no patient had a history of urinary incontinence, 14 patients experienced urinary incontinence after receiving risperidone. Moreover, 4 of these 14 patients also had fecal incontinence. Among the variables we examined, the only significant difference between groups was in sex, with significantly more women experiencing incontinence compared with men. When the dose of risperidone was reduced or the patients switched to other drugs, urinary incontinence of the patients improved.Hence, risperidone may have a casual relationship with urinary incontinence. Further research is needed to understand the pathophysiology of possible effect.

Abstract
BACKGROUND Asperger׳s Syndrome (AS) is a neurodevelopmental disorder included in the Autism Spectrum (ASD). The current literature shows growing evidence of a high rate of comorbidity between AS and other psychiatric disorders, particularly Bipolar Disorder (BD). We reviewed available epidemiological and clinical data on BD-AS comorbidity and its diagnostic and therapeutic implications METHODS A systematic review of the literature was conducted through PubMed, Scopus and Psych-Info using combinations of the following search terms: Asperger׳s Syndrome, Bipolar Disorder, depression, mood disorder, psychiatric comorbidity, treatment, mood stabilizers, anticonvulsants, antipsychotics, and antidepressants. RESULTS BD prevalence in adults with AS ranges from 6% to 21.4% of the cases. Relatives of patients with AS showed a doubled risk of being affected by BD and a BD prevalence near to 10%. When comorbid with AS, BD assumes peculiar features which might shape its under-recognition or misdiagnosis (especially schizophrenia when psychotic symptoms are prominent). Although controlled data on pharmacological treatments in BD-AS comorbidity are substantially lacking, information is derived by open observations, case series and chart reviews. Mood stabilizers should be considered the first choice, and antipsychotics, especially second generation drugs (SGA) with 5-HT2a antagonism, have been shown useful in controlling psychotic and behavioral symptoms and improving social withdrawal. Some evidence of efficacy for the treatment of anxiety, obsessive-compulsive symptoms and depression is reported for SSRI antidepressants. The use of these drugs should be carefully monitored, because activation with hypomanic or manic switches is reported up to 54% of the treated subjects. CONCLUSION BD in AS patients is frequent, usually it onsets during adolescence and is often characterized by atypical presentation, making its correct identification particularly difficult. A correct diagnosis of BD in AS individuals has relevant implications on the choice of adequate psychopharmacological, psycho-social and rehabilitative treatments.

Abstract
The identification of autism spectrum disorders has increased dramatically over the past decade, with the latest estimates indicating prevalence as high as 1 in 54 boys. There is greater awareness of medical conditions that co-occur with autism and expansion of treatment options. Closer scrutiny has led to refinement of the diagnostic criteria, and there have been advances in genetics examining potential causal factors. Transition to adulthood is an area of growing concern, and professionals and families require guidance on this issue. This article summarizes the proceedings of the Autism Speaks conference on Treating the Whole Person with Autism: Care across the Lifespan. The conference was organized with the intent of providing a forum for both families and professionals to learn about the most current research in the field. Dr. Sue Swedo provides important background information regarding the changes in the diagnostic criteria for autism spectrum disorders. She particularly deals with the concerns of individuals and families that their autism diagnosis may change. Recommendations for genetic testing and its interpretation are provided by Dr. David Miller. His discussion helps make sense of the utility of genetic testing for ASD, along with demonstration of the complexity of determining which genetic factors are doing what and through which pathways. Dr. Jeremy Veenstra-VanderWeele provides useful background information on how medicines are initially identified and for what purpose and goes on to describe the present and future treatments in pharmacology. Medical issues are addressed by Dr. Paul Carbone, especially the coordination of comprehensive services through the medical home model of care. Dr. Julie Lounds Taylor concludes with guidance on preparation for adulthood, a topic of great importance to families as their child matures and for the professionals who will help guide this transition.

Abstract
Atypical antipsychotics are increasingly used in the treatment of severe behavioral disturbances in people with pervasive developmental disorders. Among these compounds, risperidone has been the most broadly studied. This drug profile will review the available data on the use of risperidone in individuals with pervasive developmental disorders. In addition, the chemistry, pharmacokinetics, pharmacodynamics and metabolism of risperidone are discussed. Emphasis will be placed on adverse effects associated with risperidone in these people, including a discussion of measures that can be taken to monitor for these effects. Finally, a discussion of the future direction of risperidone use in this population and key issues will be presented.

Individuals diagnosed with autism spectrum disorders (ASD) often exhibit serious behavioral disturbance (irritability) including severe tantrums, aggression, and self-injury that requires pharmacologic management. Research focused on the treatment of severe irritability has primarily involved the atypical antipsychotics, including risperidone and aripiprazole. Anticonvulsants have also been investigated for targeting serious behavioral disturbance; however findings have been mixed. Advances in the pharmacotherapy of irritability in ASD continue to inform practice. Research is needed to develop safer and more effective drug treatments for serious behavioral disturbance in this population.

Weight gain and increase of body mass index among children and adolescents treated with antipsychotics: a critical review. Eur Child Adolesc Psychiatry 2013; 22:457-79.

Abstract
We performed an updated review of the available literature on weight gain and increase of body mass index (BMI) among children and adolescents treated with antipsychotic medications. A PubMed search was conducted specifying the following MeSH terms: (antipsychotic agents) hedged with (weight gain) or (body mass index). We selected 127 reports, including 71 intervention trials, 42 observational studies and 14 literature reviews. Second-generation antipsychotics (SGAs), in comparison with first-generation antipsychotics, are associated with a greater risk for antipsychotic-induced weight gain although this oversimplification should be clarified by distinguishing across different antipsychotic drugs. Among SGAs, olanzapine appears to cause the most significant weight gain, while ziprasidone seems to cause the least. Antipsychotic-induced BMI increase appears to remain regardless of the specific psychotropic co-treatment. Children and adolescents seem to be at a greater risk than adults for antipsychotic-induced weight gain; and the younger the child, the higher the risk. Genetic or environmental factors related to antipsychotic-induced weight gain among children and adolescents are mostly unknown, although certain genetic factors related to serotonin receptors or hormones such as leptin, adiponectin or melanocortin may be involved. Strategies to reduce this antipsychotic side effect include switching to another antipsychotic drug, lowering the dosage or initiating treatment with metformin or topiramate, as well as non-pharmacological interventions. Future research should avoid some methodological limitations such as not accounting for age- and sex-adjusted BMI (zBMI), small sample size, short period of treatment, great heterogeneity of diagnoses and confounding by indication.

Abstract
BACKGROUND Autistic disorder is a neuropsychiatric syndrome characterized by deficits in social interaction; qualitative impairments in communication; and restricted, repetitive, and stereotyped patterns of behavior, interests, or activities. It is classified as a type of pervasive developmental disorder (PDD). All PDDs have a qualitative impairment in social relatedness. However, many individuals with PDDs have interfering symptoms, including irritability (aggression, self-injurious behavior, and severe tantrums). Behavioral therapy is often helpful in decreasing these behaviors; however, sometimes adjunctive medications are needed, because of the intensity and severity of irritability. Numerous medications have been tested on patients with PDDs. Although many of these medications have been demonstrated to be useful, no clear main treatment for PDD has emerged. Despite the efficacy of some of the medicines, acceptability and side effects have proven to be barriers to their use. Yokukansan (TJ-54), a traditional Japanese medicine, is composed of seven kinds of dried herbs. It is widely prescribed in clinical situations for treating psychiatric disorders by acting mainly on the glutamatergic and serotonergic nervous system. Recent studies indicate that TJ-54 may be safe and useful in treating behavioral and psychological symptoms in dementia patients. We aimed at evaluating both the efficacy and the safety of TJ-54 in patients with PDDs. METHODS This was a 12 week prospective, open-label investigation of TJ-54 in 20 children and adolescents ages 6-17 years diagnosed with PDDs. Primary outcome measures included the Clinical Global Impressions-Improvement of Illness Scale (CGI-I), Children's Global Assessment Score (CGAS), and the Aberrant Behavior Checklist (ABC) irritability subscale. RESULTS Twenty subjects, ages 6-17 years, received TJ-54 in the dosage range of 2.5-7.5 g/day. The CGI-I was significantly improved from 8 weeks (p<0.001). The mean CGAS was 31.92 at baseline, whereas the mean final score at 12 weeks was 54.52 (p<0.001). The ABC irritability/agitation subscale (subscale 1) was significantly improved from 8 weeks, and the hyperactivity/noncompliance subscale (subscale 4) was significantly improved in 12 weeks. TJ-54 was well tolerated. No subject left the study because of a drug-related adverse event. CONCLUSIONS These preliminary data suggest that TJ-54 may be effective and well tolerated for the treatment of severe irritability/agitation and hyperactivity/noncompliance in children and adolescents ages 6-17 years with PDD. However, given the characteristics of this trial, the present findings should be taken cautiously, and larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of TJ-54 in this understudied population.

Abstract
RATIONALE Individuals with autistic disorder (autism) frequently exhibit significant irritability marked by severe tantrums, aggression, and self-injury. Despite advances in the treatment of this symptom domain in autism, there remains an ongoing need for more effective and better tolerated pharmacotherapies. OBJECTIVES The aim of this study is to determine the effectiveness and tolerability of paliperidone for irritability in autism. METHODS This is a prospective, 8-week open-label study of paliperidone in 25 adolescents and young adults with autism. Primary outcome measures included the Clinical Global Impressions-Improvement (CGI-I) Scale and the Irritability subscale of the Aberrant Behavior Checklist (ABC-I). Concomitant medications (except antipsychotics) were permitted if dosages were stable for ≥2 months. RESULTS Twenty-one (84 %) of 25 subjects ages 12-21 years (mean 15.3 years) responded to paliperidone, based on a CGI-I Scale score of 1 or 2 (very much or much improved) and ≥25 % improvement on the ABC-I. The mean final dosage of paliperidone was 7.1 mg/day (range 3-12 mg/day). Two subjects discontinued paliperidone prior to study completion (moderate sedation, n = 1; nonresponse, n = 1). Mild-to-moderate extrapyramidal symptoms were recorded in four subjects. A mean weight gain of 2.2 ± 2.6 kg (range -3.6 to +7.9 kg) was recorded. Mean age- and sex-normed body mass index increased from 23.6 to 24.2 (p ≤ 0.001). Mean serum prolactin increased from 5.3 to 41.4 ng/mL (p ≤ 0.0001). CONCLUSIONS Paliperidone treatment was associated with significant improvement in irritability and was generally well tolerated. Larger scale, placebo-controlled studies are needed to elucidate the efficacy and tolerability of paliperidone in this population.

Abstract
Risperidone is widely used in children with autism spectrum disorders for behavioral modification. In this study, the authors aimed to (1) describe a clinic-referred sample of patients with an autism spectrum disorder on risperidone, (2) identify differences between the success and nonsuccess groups, and (3) describe our experience with young children (< age 5 years) on risperidone. Eighty patients were initiated on risperidone. Indications included aggression (66%), impulsivity (14%), and stereotypies (4%). Sixty-six percent met criteria for success at 6 months and 53% at 1 year. Sixty-seven percent of the nonsuccess group reported side effects, compared to 47% of the success group. Weight gain was the most common side effect in both groups, followed by somnolence. Somnolence was the most robust predictor of nonsuccess. In our clinic-referred sample, the short-term success rate of risperidone was more than 50%, and side effects limited its use. Although weight gain was common, somnolence more significantly influenced treatment discontinuation.

Abstract
In the care of children with autism spectrum disorders (ASD), medical treatment is typically considered an adjunct to educational and behavioral interventions. Nonetheless, large proportions of children with ASD are managed medically and receive both pharmacologic and complementary-alternative medicine (CAM) treatments. Although many medical treatments have been studied in children with ASD, studies vary widely in terms of the sample, sample size, research design, purposes of treatment, and measurements of change. Surprisingly, comprehensive reviews of the options for medical management in ASD are lacking, particularly reviews that address both pharmacologic and CAM treatments. Furthermore, reviews to date tend to emphasize general effects of medication; this perspective contradicts medical practice, which targets particular symptoms during treatment selection and monitoring. This review of 115 studies adds to the ASD treatment literature by (1) including studies of individuals 0 to 22 years of age; (2) aggregating studies of pharmacologic treatments and CAM treatments; and importantly, (3) organizing treatment response by ASD symptoms, differentiating core and associated symptoms.

Abstract
Autism is a neurodevelopmental disorder characterized by abnormal reciprocal social interactions, communication deficits, and repetitive behaviors with restricted interests. BTBR T+tf/J (BTBR) is an inbred mouse strain that shows robust behavioral phenotypes with analogies to all three of the diagnostic symptoms of autism, including well-replicated deficits in reciprocal social interactions and social approach, unusual patterns of ultrasonic vocalization, and high levels of repetitive self-grooming. These phenotypes offer straightforward behavioral assays for translational investigations of pharmacological compounds. Two suggested treatments for autism were evaluated in the BTBR mouse model. Methyl-6-phenylethynyl-pyridine (MPEP), an antagonist of the mGluR5 metabotropic glutamate receptor, blocks aberrant phenotypes in the Fmr1 mouse model of Fragile X, a comorbid neurodevelopmental disorder with autistic features. Risperidone has been approved by the United States Food and Drug Administration for the treatment of irritability, tantrums, and self-injurious behavior in autistic individuals. We evaluated the actions of MPEP and risperidone on two BTBR phenotypes, low sociability and high repetitive self-grooming. Open field activity served as an independent control for non-social exploratory activity and motor functions. C57BL/6J (B6), an inbred strain with high sociability and low self-grooming, served as the strain control. MPEP significantly reduced repetitive self-grooming in BTBR, at doses that had no sedating effects on open field activity. Risperidone reduced repetitive self-grooming in BTBR, but only at doses that induced sedation in both strains. No overall improvements in sociability were detected in BTBR after treatment with either MPEP or risperidone. Our findings suggest that antagonists of mGluR5 receptors may have selective therapeutic efficacy in treating repetitive behaviors in autism.

Abstract
OBJECTIVE This study aims to evaluate ADHD-like symptoms in children with autism spectrum disorder (ASD) based on single-item analysis, as well as the comparison of two ASD subsamples of children with ADHD (ASD+) and without ADHD (ASD-). METHODS Participants are 83 children with ASD. Dimensional and categorical aspects of ADHD are evaluated using a diagnostic symptom checklist according to DSM-IV. RESULTS Of the sample, 53% fulfill DSM-IV criteria for ADHD. The comparison of the ASD+ and the ASD- samples reveals differences in age and IQ. Correlations of ADHD and PDD show significant results for symptoms of hyperactivity with impairment in communication and for inattention with stereotyped behavior. Item profiles of ADHD symptoms in the ASD+ sample are similar to those in a pure ADHD sample. CONCLUSION The results of our study reveal a high phenotypical overlap between ASD and ADHD. The two identified subtypes, inattentive-stereotyped and hyperactive-communication impaired, reflect the DSM classification and may theoretically be a sign of two different neurochemical pathways, a dopaminergic and a serotonergic.

Abstract
BACKGROUND Pervasive developmental disorders (PDDs) are severe psychiatric disorders characterized by impairment in social interactions, in verbal and non-verbal communication, and by restricted and stereotyped patterns of interest and behaviour, with onset in the first 3 years of life. The appropriate use of pharmacotherapy can improve some aberrant symptoms and behaviours and increase the person's response to non-pharmacological interventions. OBJECTIVE To describe clinical outcomes, or symptom changes, and adverse effects during naturalistic treatment with aripiprazole monotherapy in children with PDDs and severe behavioural disorders (such as aggression against self and/or others, hostility, hyperactivity, severe impulsiveness). METHOD This retrospective naturalistic study included 34 patients (23 males and 11 females, age range 4.5-15 years, mean age 10.2 +/- 3.3 years), admitted during 2006-2007, diagnosed according to DSM-IV criteria and followed up for 4-12 months (mean 7.0 +/- 3.6 months). Outcome measures were three global measures of clinical and functional impairment and improvement from baseline: the Clinical Global Impression-Severity (CGI-S) and CGI-Improvement (CGI-I) scales; the Children's Global Assessment Scale (C-GAS); and the Childhood Autism Rating Scale (CARS), a specific measure of PDD symptoms. RESULTS The mean baseline CGI-S was 5.7 +/- 0.8 (markedly ill/severely ill). The mean final dosage of aripiprazole was 8.1 +/- 4.9 mg/day. At the endpoint, 11 patients (32.4%) were 'much improved' or 'very much improved' (CGI-I score of 1 or 2), 12 patients (35.3%) were 'minimally improved' (CGI-I score of 3) and 10 (29.4%) were 'unchanged' or 'worsened' (CGI-I score of 4 or 5). C-GAS and CARS scores significantly improved (p < 0.0001, effect sizes 0.59 and 0.62, respectively). Nine patients (26.5%) experienced moderate to severe agitation, which was associated with self-injurious behaviours in five of these patients, and five patients presented with sleep disorders. Twelve patients (35.3%) discontinued medication during the follow-up because of lack of efficacy or adverse effects. CONCLUSIONS In these severely impaired children with PDDs, aripiprazole monotherapy was associated with a significant improvement in maladaptive behaviours in one-third of patients. Agitation and insomnia were the most frequent adverse effects. Further controlled studies in larger samples to explore possible predictors of efficacy are warranted.

Abstract
Recently, atypical antipsychotic treatments have been used in children with autistic disorder (AD). However, data on safety and efficacy of atypical antipsychotic agents in autistic children are limited. In this open, prospective trial, subjects were treated with risperidone for six weeks. Nineteen children (12 male, 7 female) aged 4 to 8 years were started on 0.5 mg daily with individual titration to a maximum of 1.5 mg daily. Behavioural assessments were completed by Conner's parent 10-item index, AD symptom checklist and CGI-Global improvement. Statistically significant improvement was observed in mean total scores of Conner's parent 10-item index from baseline to the end of study (p< 0.001). On the basis of the CGI-Global improvement item, 15 children were considered responders. Statistically significant improvement was also found in some aspects of social contact, impulsive-aggression and repetitive, ritualistic behaviour based on assessment with the AD-symptom checklist. Weight gain and increase in night-time sleep were the most frequent side effects.

Full-scale intelligence quotient (IQ) scores ranged from 48 to 122 (mean 84). Twenty-two (88%) of 25 subjects were responders in regard to interfering symptoms of irritability, including aggression, self-injury, and tantrums, with a final CGI-I of 1 or 2 (very much or much improved) and a 25% or greater improvement on the ABC-I. The final mean CGI-I was 1.6 (p CONCLUSIONS These preliminary data suggest that aripiprazole may be effective and well tolerated for severe irritability in pediatric patients with PDD-NOS or Asperger's disorder. Larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of aripiprazole in this understudied population.

Abstract
Challenging behaviors in persons with intellectual disabilities are primary target for treatment in mental health clinics and institutions. Furthermore, an increasing number of people are receiving psychotropic medications for the management of their challenging behaviors. Many people are often treated with high doses of multiple psychotropic medications for extended periods of time with little or no data collected to determine treatment efficacy. Similarly, data demonstrating treatment effectiveness is at best questionable at this time. It is for these reasons that controversy exists regarding the use of psychotropic medication for challenging behaviors. The purpose of this paper was to summarize past and current studies of drug related interventions for challenging behaviors for persons with intellectual disabilities. Based on the results of this review, the effectiveness of psychotropic medications in managing challenging behaviors is best described as minimal and a need exists for controlled studies of higher scientific quality in this area. Considering alternative psychologically based interventions and careful functional assessments appear to be advisable.

Abstract
Autism is a neurodevelopmental condition affecting 1 out of 160 children in the United States today. Only risperidone has Food and Drug Administration approval for the pharmacologic management of autism in children. However, health care providers may prescribe other drugs used off-label to assist autistic children and their families with the core deficits and associated behaviors of this condition. Evidence for the use of these medications will be discussed in this continuing education offering. Meta analyses, randomized clinical trials, and other prospective experimental studies of pharmacotherapy conducted in the United States in the past 10 years in children between the ages of 5 and 15 years were reviewed. The results support moderate success in treating the associated behaviors of autism and minimal success in treating core deficits across all drug classes. Preliminary evidence demonstrates possible uses for atypical antipsychotic agents, selective-serotonin reuptake inhibitors, stimulants, and N-methyl-D-aspirate receptor antagonists in decreasing the core behaviors and associated symptoms of autism. More studies and longer periods of follow-up are needed before definitive guidelines can be suggested.

Abstract
In a plural and multidisciplinary process of care, it would be fruitful to ally complementary, pharmacologic and psychodynamic approaches. We have done a review of the literature on the effectiveness and the cautions for prescription of risperidone, a second generation antipsychotic drug. Risperidone has proved helpful in treating children and adolescents with autism spectrum, conduct and bipolar disorders, Tourette's syndrome, and schizophrenia. The principal side effects are sedation, weight gain, and metabolic disturbances. Extrapyramidal symptoms, QTc prolongation, and hyperprolactemia with clinical signs are infrequent and not clinically significant. The benefit/risk is clearly in favor of the prescription when it is accompanied with the precautions and with the adequate monitoring.

Abstract
BACKGROUND The focus of this review is on methods that are currently being used to evaluate the behavioural effects of medication for individuals with intellectual disabilities. First we describe what has been identified as the ideal criteria for conducting clinical trials and how these criteria may be adapted to do less controlled evaluations. The central theme is a review of the biological measures (e.g. labs, drug levels), behavioural rating scales and direct observation measures that are often used to evaluate medication effects. Issues related to how the side effects of medication can affect behaviour will also be discussed. CONCLUSION The importance of encouraging communication and collaboration across all systems of care and the use of socially valid measures are discussed.

Abstract
The aim of this study was to evaluate long-term weight gain associated with clozapine, olanzapine, and risperidone treatment and its clinical risk factors in children and adolescents. At four child and adolescent psychiatric departments, the weight and body mass index of initially hospitalized patients (aged 9.0-21.3 years) treated with clozapine (n = 15), olanzapine (n = 8), and risperidone (n = 10) were prospectively monitored for 45 weeks. Clinical risk factors (age, gender, baseline weight, dosage, drug-naivety) were tested for their association with weight gain in the three groups. All three groups experienced significant weight gain between baseline and endpoint. The absolute and percentage average weight gains were significantly higher for the olanzapine group (16.2 +/- 8.8 kg; 30.1 +/- 18.9%) than for the clozapine (9.5 +/- 10.4 kg; 14.8 +/- 15.8%) and the risperidone (7.2 +/- 5.3 kg; 11.5 +/- 6.0%) groups. Olanzapine is associated with extreme long-term weight gain in children and adolescents that, in addition, is much higher than that expected in adults. Clozapine and risperidone are associated with a less marked weight gain in children and adolescents but also much higher than that expected in adults. These differences may affect compliance with medication and health risk.

Abstract
Severe intellectual and developmental disabilities are frequently associated with aggression toward self and others, destruction of property, and disruption. Antipsychotic medications are a mainstay of treatment of such behaviors. National and state guidelines suggest stopping these medications or decreasing their dosages when possible if patients have maintained stability. The current study evaluated the likelihood of future antipsychotic drug withdrawal-induced relapses in those individuals where such a relapse had occurred previously. Subjects were 57 institutionalized adults with severe or profound intellectual disability. Between 1990 and 2000, each had experienced an initial activation of maladaptive aggressive behaviors after an attempt at antipsychotic drug withdrawal and/or termination. Quarterly behavioral reports were evaluated to determine whether subsequent antipsychotic drug withdrawal attempts were also associated with future relapses. Initial relapse was followed by subsequent antipsychotic drug withdrawal attempts in 49 of the 57 individuals. Between 1990 and 2005, 28.6% of these 49 subjects had experienced 1, 38.7% had 2, 20.4% had 3, and 8.2% had 4 additional relapses. Two (4.1%) had not relapsed. Eight individuals remained on antipsychotic agents without a subsequent withdrawal attempt. By the end of 2005, only 4 (7%) of the 57 individuals had become antipsychotic drug free, 22.8% were receiving first-generation antipsychotic agents alone, 45.6% were receiving second-generation antipsychotic agents alone, and 24.6% were receiving a combination of first- and second-generation antipsychotic agents. Thus, if relapse occurs after an antipsychotic drug withdrawal attempt, subsequent attempts at withdrawal are also very likely to lead to further relapses.

Abstract
This is a review of the clinical trials investigating the efficacy and safety of risperidone in the treatment of children with autistic spectrum disorders (ASD). The main clinical characteristics are impairment in social skills, communication difficulties, repetitive movements and behaviors, including stereotypies. Pharmacotherapy is mainly directed at the so-called target symptoms, ie, behavioral disorders and the various kinds of repetitions associated with ASD. According to the available data, risperidone seems to be moderately efficacious and safe for treating behavioral disorders. 4 double blind controlled trial. 3 reanalysis studies, and 12 open studies have documented the role of risperidone in children with ASD. Controlled studies have been thoroughly considered in this review.

Abstract
BACKGROUND The aim of the study was to investigate safety, efficacy and tolerability of risperidone in comparison with haloperidol in the long-term treatment of autistic disorder. METHODS This was an open-label continuation study of the randomized, double-blind, controlled trial of risperidone and haloperidol study for 12 week in autistic children and adolescents. A total of 28 subjects between 8 and 18 ages with autistic disorder were enrolled to the open label phase of the study. Behavioral rating scales (Clinical Global Impression Scale [CGI-I], Ritvo-Freeman Real Life Rating Scale [RF-RLRS]), Aberrant Behavior Checklist [ABC], Turgay DSM-IV Pervasive Developmental Disorder Rating Scale [TPDDRS]) and safety assessment scales (Extrapyramidal Symptoms Rating Scale [ESRS], UKU-Side Effect Rating Scale) were performed at 12, 16, 20 and 24 weeks, following the 12 week double-blind phase. Risperidone and haloperidol treatments were applied with a once daily dosage regimen as 0.01-0.08 mg/kg/day. RESULTS Risperidone led to a significant greater reduction on CGI scale. There was significant improvement on RF-RLRS sensory motor and language subscale and ABC scores in risperidone group. Weight gain was observed more frequently in the haloperidol group at week 24. CONCLUSIONS These results demonstrate that risperidone is more efficacious and well tolerated than haloperidol in the long-term maintenance treatment of autistic disorder.

Abstract
OBJECTIVE We report on an open-label, naturalistic study using risperidone to treat disruptive behaviors and self-injury in children with Down syndrome, severe intellectual disability, and comorbid autism spectrum disorders (DS+ASDs). We hypothesized that hyperactivity and disruptive behaviors would improve in response to risperidone treatment consistent with previous studies of children with ASD. METHODS Subjects were children (mean age, 7.8 +/- 2.6 years), consisting of 20 males and three females identified through our outpatient Down Syndrome Clinic between 2000 and 2004. RESULTS Using the Aberrant Behavior Checklist as the primary outcome measure, all five subscales showed significant improvement following risperidone treatment. The mean duration of treatment was 95.8 +/- 16.8 days, and mean total daily dose was 0.66 +/- 0.28 mg/day. The Hyperactivity, Stereotypy, and Lethargy subscale scores showed the most significant reduction (p < .001), followed by Irritability (p < .02), and Inappropriate Speech (p < .04). Children with disruptive behavior and self-injury showed the greatest improvement. Sleep quality improved for 88% of subjects with preexisting sleep disturbance. Subjects for whom a follow-up weight was available showed a mean weight increase of 2.8 +/- 1.5 kg during the treatment period. CONCLUSIONS These findings support our clinical impression of improvement on important target behaviors such as aggression, disruptiveness, self-injury, stereotypy, and social withdrawal. Low-dose risperidone appears to be well tolerated in children with DS+ASD, although concerns about weight gain and metabolic alterations may limit its usefulness over the long term in some children.

Abstract
OBJECTIVE The aim of the study was to compare safety, efficacy and tolerability of risperidone with haloperidol in the treatment of Autistic Disorder (AD). METHOD This study was designed as a double-blind, prospective, for a 12-week period. A total of 30 subjects, between the ages of 8 and 18 with AD based on DSM IV criteria, were included in the study. Behavioral Rating Scales were performed by the investigators and the parents. Safety assessment included vital signs, electrocardiogram, electroencephalogram, adverse events, laboratory tests, extrapyramidal symptoms and the side effects. Both treatments were applied in a once daily dosage regimen of 0.01-0.08 mg/kg/day. RESULTS The reduction from baseline in Ritvo-Freeman Real Life Rating Scale (RF-RLRS), sensory motor (subscale I) and language (subscale V) scores were significant in risperidone group (P < 0.05). Compared to haloperidol, risperidone led to a significantly greater reduction in the Aberrant Behavior Checklist (ABC) and Turgay DSM-IV Pervasive Developmental Disorder (PDD) scale scores (P < 0.05 and P < 0.01). There was a greater increase of prolactin in the risperidone group, while alanine amino transferase (ALT) had further increased in the haloperidol group. Sensory motor behaviors (subscale I) and language at the end of the 12th week, RF-RLRS sensory motor and language subscale scores decreased in the risperidone group further than the other group (P < 0.05). CONCLUSIONS Risperidone was found to be more effective than haloperidol in the treatment of behavioral symptoms, impulsivity, language skills, and impaired social relations in children with AD. These results demonstrated that both drugs were safe and well tolerated in the treatment of AD.

Abstract
The treatment of pervasive developmental disorders (PDDs) is a challenging task, which should include behavioral therapy modifications as well as pharmacologic therapy. There has been a lack of data on using medications in children with PDDs until recent years. Within the last 10 years, an increase in clinical research has attempted to provide efficacy and safety data to support the use of medications in children with PDDs. Double-blinded and open-label research of atypical antipsychotics has been of particular focus. Evidence shows that atypical antipsychotics (AAs) may be useful in treating certain symptoms associated with PDDs, such as aggression, irritability, and self-injurious behavior. This article reviews the literature regarding the use of AAs in children with PDDs. Of the AAs, risperidone has the largest amount of evidence with five published double-blinded, placebo-controlled trials and nine open-label trials. These risperidone trials have consistently shown improvements in aggression, irritability, self-injurious behavior, temper tantrums, and quickly changing moods associated with autistic disorder and other PDDs. Data for the other AAs are limited, but ziprasidone and aripiprazole appear to be promising treatment options. Based on clinical trials, olanzapine and quetiapine have shown minimal clinical benefit and a high incidence of weight gain and sedation. It should be noted that all AAs do have a risk of metabolic syndrome, and patients should be monitored appropriately while receiving these medications. Overall, AAs can be beneficial in alleviating behavioral symptoms, and should be considered an appropriate therapeutic option, as part of a comprehensive treatment strategy, for children with PDD.

Abstract
INTRODUCTION Aripiprazole is a novel second-generation antipsychotic approved for the treatment of bipolar disorder in adults but there is no systematic data available in pediatric bipolar disorder. METHODS This was an 8-week, open-label, prospective study of aripiprazole 9.4+/-4.2 mg/day monotherapy to assess the efficacy and tolerability of this compound in treating pediatric bipolar disorder. Assessments included the Young Mania Rating Scale, Clinical Global Impressions-Improvement scale, and Brief Psychiatric Rating Scale. Adverse events were assessed through spontaneous self-reports, vital signs weight monitoring, and laboratory analysis. RESULTS Fifteen of the 19 bipolar youth (79%) completed the study. Aripiprazole treatment was associated with clinically and statistically significant improvement in mean Young Mania Rating Scale scores (-18.0+/-6.9, P<.0001). With the important exception of two cases of extrapyramidal symptoms that precipitated dropout, aripiprazole was well tolerated with no statistically significant increase in body weight (1.8+/-1.7 kg, P=.2). CONCLUSION Open-label aripiprazole treatment was beneficial in the treatment of mania in youth with bipolar disorder. Future placebo-controlled, double-blind studies are warranted.

Abstract
Autism is a dynamic neurodevelopmental syndrome in which disabilities emerge during the first three postnatal years and continue to evolve with ongoing development. We briefly review research in autism describing subtle changes in molecules important in brain development and neurotransmission, in morphology of specific neurons, brain connections, and in brain size. We then provide a general schema of how these processes may interact with particular emphasis on neurotransmission. In this context, we present a rationale for utilizing pharmacologic treatments aimed at modifying key neurodevelopmental processes in young children with autism. Early treatment with selective serotonin reuptake inhibitors (SSRIs) is presented as a model for pharmacologic interventions because there is evidence in autistic children for reduced brain serotonin synthesis during periods of peak synaptogenesis; serotonin is known to enhance synapse refinement; and exploratory studies with these agents in autistic children exist. Additional hypothetical developmental interventions and relevant published clinical data are described. Finally, we discuss the importance of exploring early pharmacologic interventions within multiple experimental settings in order to develop effective treatments as quickly as possible while minimizing risks.

Abstract
BACKGROUND Shared candidate gene regions point to a link between autistic disorders and attention-deficit/hyperactivity disorder (ADHD). Although they represent nosologically different diagnoses, the disorders do show some shared symptoms, above all inattention. For both disorders, the association with the serotonergic system is a focus of current research. SAMPLING AND METHODS The current work provides an overview of serotonergic mechanisms in ADHD and autistic disorders as well as the resulting pharmacogenetic approaches. RESULTS No uniform picture emerges either for ADHD or for autistic disorders. In pharmacogenetic terms, there are some isolated studies on associations between serotonergic mechanisms and pharmacotherapy. For the area of autism, such studies are still lacking. CONCLUSIONS The presented serotonergic mechanisms show relationships of this polymorphism to ADHD and autistic disorders, but they do not result in a uniform picture. The overlaps can best be explained by a dimensional classification approach. As yet, only a small number of studies on attentional disorders in autism and ADHD using shared samples have been carried out. With regard to diagnostics and therapy, analyses on the etiology of the attentional disorder of ADHD and autism are required.

Abstract
The use of antipsychotics in children and adolescents in the clinical setting is increasing. This article reviews 77 clinical trials published in the last 10 years, investigating their efficacy, effectiveness, safety and pharmacokinetic data in paediatric populations. The diagnostic categories in which the antipsychotics are commonly used (schizophrenia, pervasive developmental disorders, Tourette's disorder, mental retardation/subaverage intelligence, mood disorders and disruptive behaviour disorders) were used in order to review the evidence and effectiveness. All randomised, double-blind, placebo-controlled trials from the past decade are also summarised. This review refers to recent relevant practice parameters, guidelines and reviews throughout the text. Consistent with previous reviews, it is concluded that the recent trend of increased use of antipsychotics in children and adolescents is not adequately supported by evidence. Specific suggestions have been provided on how to incorporate the existing evidence base into clinical decision making. The review ends with the authors' opinion on the clinical and research implications for the field and future directions.
