Asperger syndrome, also known as Asperger's syndrome or Asperger disorder, is an autism spectrum disorder (ASD) that is characterized by significant difficulties in social interaction, alongside restricted and repetitive patterns of behavior and interests.It differs from other autism spectrum disorders by its relative preservation of linguistic and cognitive development. Although not required for diagnosis, physical clumsiness and atypical use of language are frequently reported.[1][2]

Asperger syndrome is named after the Austrian pediatrician Hans Asperger who, in 1944, studied and described children in his practice who lacked nonverbalcommunication skills, demonstrated limited empathy with their peers, and were physically clumsy.[3] Fifty years later, it was standardized as a diagnosis, but many questions remain about aspects of the disorder.[4] For example, there is doubt about whether it is distinct from high-functioning autism (HFA);[5] partly because of this, its prevalence is not firmly established.[1] It has been proposed thatthe diagnosis of Asperger's be eliminated, to be replaced by a diagnosis of autism spectrum disorder on a severity scale.[6]

The exact cause is unknown, although research supports the likelihood of a genetic basis; brain imaging techniques have not identified a clear common pathology.[1] There is no single treatment, and the effectiveness of particular interventions is supported by only limiteddata.[1] Intervention is aimed at improving symptoms and function. The mainstay of management is behavioral therapy, focusing on specific deficits to address poor communication skills, obsessive or repetitive routines, and physical clumsiness.[7] Most children improve as they mature to adulthood, but social and communication difficulties may persist.[4] Some researchers and people with Asperger'shave advocated a shift in attitudes toward the view that it is a difference, rather than a disability that must be treated or cured.[8][9]

Classification

Asperger syndrome (AS) is one of the autism spectrum disorders (ASD) or pervasive developmental disorders (PDD), which are a spectrum of psychological conditions that are characterizedby abnormalities of social interaction and communication that pervade the individual's functioning, and by restricted and repetitive interests and behavior. Like other psychological development disorders, ASD begins in infancy or childhood, has a steady course without remission or relapse, and has impairments that result from maturation-related changes in various systems of the brain.[10] ASD, inturn, is a subset of the broader autism phenotype (BAP), which describes individuals who may not have ASD but do have autistic-like traits, such as social deficits.[11] Of the other four ASD forms, autism is the most similar to AS in signs and likely causes, but its diagnosis requires impaired communication and allows delay in cognitive development; Rett syndrome and childhood disintegrative...
