[Functional adaptation and disorders of the autistic spectrum].

Autism spectrum disorders (ASD) are neurodevelopmental disorders that affect social communication and present stereotyped behaviors; 30% of the cases diagnosed with ASD have intellectual disability and 2/3 an intellectual capacity within the norm. Although cognitive ability is related to better functional adaptation, however, the vast majority of people with ASD in adulthood have limited autonomy and are dependent on adults. In this article we review the concept of functional adaptation, its relationship with ASD, factors that influence a better functional adaptation, how to evaluate it and implications for treatment. Functional adaptation in ASD is an essential concept, related to prognosis. The knowledge of the factors involved in the functional adaptation and its measure will facilitate the incorporation of very relevant aspects for treatment.
