Ducks

A young boy with autism, and the precise line of toys that he made before falling asleep.

Autistic children may display unusual behaviors or fail to display expected behaviors.

Some behaviors cited by the National Institute of Child Health and Human Development (listed below) may simply mean a normal delay in one or more areas of development, while others are more typical of autism spectrum disorders. [1]

The list below is not all-inclusive, and generally applies to children and not adults. Furthermore, while some of these behaviors might be seen in a person with autism, others may be absent.
