Asperger's syndrome (AS) is an autism spectrum disorder marked by impaired social interactions and limited repetitive patterns of behavior, interests, and activities. This syndrome has no significant delays of language acquisition but motor skills may be delayed. Clumsiness and awkwardness may be present but are relatively mild.

It's conservatively estimated that two out of every 10,000 children have the disorder. Boys are three to four times more likely than girls to have AS.
