An Introduction To Autism
Autism was first described in 1943 by the American child psychologist, Leo Kanner. Autism is a type of neurodevelopmental disorder, and usually appears within the first three years of a child's life. The hallmark of autism is the lack of communication, and affected children have problems with language, behavior, and social skills.

Autism is a lifelong condition, and its cause is unknown. Environmental and genetic factors do contribute to the development of autism, but most children with autism have normal health, with no medical reason for the autistic symptoms. Autism is not caused by the parents.
