TL;DR: The genome-wide characteristics of rare (<1% frequency) copy number variation in ASD are analysed using dense genotyping arrays to reveal many new genetic and functional targets in ASD that may lead to final connected pathways.

TL;DR: Risperidone was effective and well tolerated for the treatment of tantrums, aggression, or self-injurious behavior in children with autistic disorder and the benefit was maintained at six months.
Journal ArticleDOI

TL;DR: Methylphenidate was often efficacious in treating hyperactivity associated with pervasive developmental disorders, but the magnitude of response was less than that seen in typically developing children with attention-deficit/hyperactivity disorder.
Journal ArticleDOI

TL;DR: Compared to children without GI problems, those with GI problems showed greater symptom severity on measures of irritability, anxiety, and social withdrawal, and were also less likely to respond to treatment.
Journal ArticleDOI
Research Units on Pediatric Psychopharmacology (RUPP) Autism Network. Background and rationale for an initial controlled study of risperidone.

TL;DR: Risperidone has potent effects on serotonin and dopamine neuronal systems, which have been implicated in the pathophysiology of autism as discussed by the authors, which has been shown to be effective for reducing many of the maladaptive behaviors associated with autism.
