A developmental disorder affecting ability to effectively socialise and communicate. Today, Asperger's syndrome is technically no longer a diagnosis on its own. Asperger syndrome (AS), also known as Asperger's, is a neurodevelopmental disorder characterized by significant difficulties in social interaction and nonverbal. Asperger syndrome, or Asperger's, is a previously used diagnosis on the autism spectrum. Asperger's syndrome (also known as Asperger's Disorder) was first described in the 1940s by Viennese pediatrician Hans Asperger, who observed autism-like behaviors and difficulties with social and communication skills in boys who had normal intelligence and language development. Asperger's Syndrome is one of the disorders that is generally considered high functioning on the Autism spectrum.
