FACTS ABOUT AUTISM
Autism is a developmental disorder characterised by impaired social interaction and verbal and non – verbal communication, and by restricted or stereotyped behaviour. The diagnostic criteria require that symptoms become apparent before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organise; how this occurs is not well understood. It is one of three recognized disorders in the autism spectrum (ASDs), the other two being Asperger syndrome, which lacks delays in cognitive development and language, and pervasive developmental disorder, not otherwise specified (commonly abbreviated as PDD-NOS) which is diagnosed when the full set of criteria for autism or Asperger syndrome are not met.
