Asperger syndrome.

Asperger syndrome (AS) is a chronic neurodevelopmental disorder of social interaction, communication, and a restricted range of behaviors or interests. Although not generally associated with intellectual disability, the severe social disability and, in many cases, associated mental health and other medical problems, result in disability throughout life. The diagnosis is often delayed, sometimes into adulthood, which is unfortunate because there are now a range of interventions available, and the current evidence supports intervention starting as early in childhood as possible. The aim of this review is to present a description of AS, an up to date synopsis of the literature pertaining to its etiology, co-morbidity and intervention options, and a discussion of current nosological controversies.
