Autism

Autism is a disorder qualified by impaired social interaction and communicating, and by restricted and repetitious behavior. These signs all begin before a kid is three years old. Autism has a potent genetic basis, although the genetics of autism are composite and it is unclear whether ASD is explained more by uncommon mutations, or by rare combinations of common genetic variants. In rare cases, autism is strongly associated with agents that cause birth defects. Controversies surround other proposed environmental causes, such as heavy metals, pesticides or childhood vaccines; the vaccine hypotheses are biologically implausible and lack convincing scientific evidence. The prevalence of autism is about 1–2 per 1,000 people; the prevalence of ASD is about 6 per 1,000, with about four times as many males as females. The number of people diagnosed with autism has increased dramatically since the 1980s, partly due to changes in diagnostic practice; the question of whether actual prevalence has increased is unresolved.
Parents often signs in the first two years of life for their children. The signs often occur gradually, but some autistic children come first most often and then back. Although early intervention or cognitive behavior can help autistic children to gain self-care, social, and communication skills, there is no known cure. Not many children with autism live independently after reaching adulthood, but some are successful. An autistic culture has developed, with some people in search of a cure for autism and other believers should be tolerated as the difference and not treated as a disorder.
