Autism was first described by and recognized as a disease by Leo Kanner, a scientist, in 1943.

A child with autism often has extreme difficulties in relating to other people. The child will often avoid such basic communication as eye contact and is frequently described as being in a world of their own. Attempts to break into their world can provoke frustration and may lead to tantrums. A child with autism often resists being held and is generally indifferent to the social approaches of others.

People with autism seem to have difficulty in making sense of their environment. This may account, in part, for the obsessive nature of their behavior. They are reducing the world to sections that they can understand and with which they feel safe. These reactions can change from day to day.
