BACKGROUND The repetitive behaviors seen in autism phenotypically resemble those seen in obsessive-compulsive disorder (OCD) and Tourette Syndrome (TS), disorders in which structural and functional abnormalities of the basal ganglia (BG) are present and correspond to the severity of repetitive behaviors. METHODS Seventeen subjects with autism by DSM-IV(More)
BACKGROUND Oxytocin dysfunction might contribute to the development of social deficits in autism, a core symptom domain and potential target for intervention. This study explored the effect of intravenous oxytocin administration on the retention of social information in autism. METHODS Oxytocin and placebo challenges were administered to 15 adult subjects(More)
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(More)
Autism is a neurodevelopmental disorder characterized by impairment in three core symptom domains: socialization, communication, and repetitive/stereotyped behaviours. Other associated symptom domains are also affected including impulsivity/aggression, self-injury, anxiety, and mood lability. Divalproex has been shown to have efficacy in treating epilepsy,(More)
Atypical antipsychotics have been shown to improve disruptive and repetitive behaviors in pervasive developmental disorders (PDDs), but they require assessment of potential side effects. This is the first placebo-controlled trial of olanzapine in the treatment of children and adolescents with PDD. Eleven patients with a diagnosis of either autism,(More)
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(More)
UNLABELLED BACKGROUND There are no effective medications for the treatment of social cognition/function deficits in autism spectrum disorder (ASD), and adult intervention literature in this area is sparse. Emerging data from animal models and genetic association studies as well as early, single-dose intervention studies suggest that the oxytocin system(More)
Autism spectrum disorders (ASDs) are neurodevelopmental disorders characterized by social and language deficits and by repetitive behaviors and interests. Irritability/aggression is a significant comorbid symptom in this population, which greatly impacts burden of care. This study examined the effect of divalproex sodium for irritability/aggression in(More)
OBJECTIVE The effects of fluoxetine and placebo on repetitive behaviors and global severity were compared in adults with autism spectrum disorders (ASDs). METHOD Adults with ASDs were enrolled in a 12-week double-blind placebo-controlled fluoxetine trial. Thirty-seven were randomly assigned to fluoxetine (N=22) or placebo (N=15). Dosage followed a fixed(More)
