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.
