Whats is Autism disease?!
Question: Whats is Autism disease!?
Answers:
Autism is a brain development disorder that is characterized by impaired social interaction and communication, and restricted and repetitive behavior, all starting before a child is three years old!. This set of signs distinguishes autism from milder autism spectrum disorders (ASD) such as pervasive developmental disorder not otherwise specified (PDD-NOS)!.[2]
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!.[3] In rare cases, autism is strongly associated with agents that cause birth defects!.[4] Other proposed causes, such as childhood vaccines, are controversial; the vaccine hypotheses lack convincing scientific evidence!.[5] Most recent reviews estimate a prevalence of one to two cases per 1,000 people for autism, and about six per 1,000 for ASD, with ASD averaging a 4!.3:1 male-to-female ratio!. The number of people known to have autism has increased dramatically since the 1980s, at least partly as a result of changes in diagnostic practice; the question of whether actual prevalence has increased is unresolved!.[6]
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!. Early behavioral or cognitive intervention can help children gain self-care, social, and communication skills!. There is no known cure!.[7] 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]
