Autism is a disorder characterized by impaired social interaction and communication, as well as restricted and repetitive behaviors. The symptoms must be apparent before age 3. It affects how nerve cells and synapses in the brain connect and organize, though this process is not well understood. Autism is one of three conditions in the autism spectrum, along with Asperger syndrome and pervasive developmental disorder not otherwise specified.

1. Autism
Autism is a disorder of neural development characterized by impaired social
interaction and communication, and by restricted and repetitive behavior.
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 organize; 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.
