Simplified Explanation

Autism is a developmental disability that makes social interaction and communication difficult. Parents usually notice signs in the first two years of their child's life.

Some symptoms include:

restricted and repetitive behavior
difficulty communicating with the outside world
withdrawal into one's own world

People with autism can be treated and, with the help of professionals, can make progress in many areas of everyday life. They experience the world differently than others. It is not easy for them to talk to others, express themselves or understand other' language and emotions. Ordinary sounds and human touch may upset them. They may act in unusual ways, dislike changes in their routine. They may need help to make sense of the world around them.
