Medical model of autism

The medical model of autism encourages continual research into the causes of autism, with the primary goal of finding a way to prevent or cure autism. This is a subset of the medical model of disability in general. The model advocates a variety of goals including increased awareness of autism prevalence, earlier and more accessible diagnosis, elimination of autistic behaviors through therapies such as applied behavior analysis, identification of environmental factors that may cause autism in infancy, and identification of a genetic marker to allow testing for autism in utero.

Advocates for the medical model believe that autism is a disorder caused by genetic defects or environmental harm, that the value of talents attributed to autism does not outweigh the deficits, and that most autistic people would be better off if they were not autistic. For instance, then-president Liz Feld of Autism Speaks stated that one-third of people with autism also have a seizure disorder, half suffer serious digestive complications, 49 percent wander, and more than 30 percent are nonverbal.

Many organizations subscribe to the medical model, most of which have non-profit status. The autism rights and neurodiversity movements are critics of the medical view.

Autism is defined in the DSM-IV-TR as exhibiting at least six symptoms total, including at least two symptoms of qualitative impairment in social interaction, at least one symptom of qualitative impairment in communication, and at least one symptom of restricted and repetitive behavior. Sample symptoms include lack of social or emotional reciprocity, stereotyped and repetitive use of language or idiosyncratic language, and persistent preoccupation with parts of objects. Onset must be prior to age three years, with delays or abnormal functioning in either social interaction, language as used in social communication, or symbolic or imaginative play. The disturbance must not be better accounted for by Rett syndrome or childhood disintegrative disorder.
