Asperger syndrome
Asperger syndrome (also called Asperger’s syndrome, Asperger’s disorder, Asperger’s or AS) is an autism spectrum disorder (ASD), and people with AS therefore show difficulties in social interaction and restricted, stereotyped patterns of behavior and interests. AS differs from other ASDs by its relative preservation of linguistic and cognitive development. Although not mentioned in standard diagnostic criteria, physical clumsiness and atypical use of language are frequently reported.[1][2] Asperger syndrome is named after Austrian pediatrician Hans Asperger who, in 1944, described children in his practice who lacked nonverbal communication skills, demonstrated limited empathy with their peers, and were physically clumsy.[3] Fifty years later, AS was standardized as a diagnosis, but questions about many aspects remain.
