Autism has a strong genetic basis, although the genetics of autism are complex and it is unclear whether ASD is explained more by multigene interactions or by rare mutations.[4] In rare cases, autism is strongly associated with agents that cause birth defects.[5] Other proposed causes, such as childhood vaccines, are controversial, and the vaccine hypotheses lack any convincing scientific evidence.[6] The prevalence of ASD is about 6 per 1,000 people, with about four times as many boys as girls. The number of people known to have autism has increased dramatically since the 1980s, partly due to changes in diagnostic practice; the question of whether actual prevalence has increased is unresolved.[7]
Autism affects many parts of the brain; how this occurs is not understood. Parents usually notice signs in the first two years of their child's life. Although early behavioral or cognitive intervention can help children gain self-care, social, and communication skills, there is no known cure.[3] Few children with autism live independently after reaching adulthood, but some become successful,[8] and an autistic culture has developed, with some seeking a cure and others believing that autism is a condition rather than a disorder.[9]
