Abstract Autism Spectrum Disorder (ASD) are a group of pervasive developmental disorders affecting the child, the commonest of which is Autism, which is characterized by severely compromised ability to engage in, and by a lack of interest in, social interactions. All children with autism demonstrate deficits in social interaction, verbal and nonverbal communication, and repetitive behaviors or interests. In addition, they often have unusual responses to sensory experiences such as certain sounds. ASD has roots in both structural brain abnormalities and genetic predispositions, according to family studies and studies of brain anatomy. Cognitive deficits in social perception likely result from abnormalities in neural circuitry. Children with ASD have been studied with several imaging techniques, but no strongly consistent findings have emerged, although abnormalities in the cerebellum and limbic system and larger brains have been reported.
