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.
