Asperger syndrome

Asperger syndrome (AS), also known as Aspergers, is a developmental disorder characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior and interests. It is an autism spectrum disorder (ASD) and differs from other disorders by relatively normal language and intelligence. Although not required for diagnosis, physical clumsiness and unusual use of language are common. Symptoms usually begin before two years old and can last for a person's entire life.
