Imagine living in a world that doesn't completely reach you, and to which you can't always respond. For many people who have autism, this great divide exists between their world and the reality outside of them.
Autism is one of a group of developmental disorders called autism spectrum disorders. Autism affects about 1 in 68 children. Children with autism usually display signs before the age of 3. Autism is 2 to 4 times more likely in boys than girls, and people with autism may be developmentally impaired to some degree.
