Autism is a developmental disorder that appears in the first 3 years of life and affects normal brain development of social skills and communication and by restricted and repetitive behavior.These characters all begin to run until the child reaches three years.Autism affects information processing in the brain, by changing how nerve cells and their synapses to connect and organize, how this occurs is not well understood. This is one of the three recognized disorders autism spectrum disorder (broad), the other two had Asperger syndrome, which lacks the delay in cognitive development and language, and broad-based developmental disorder not otherwise specified disorders (commonly abbreviated as PDD-NOS), which is diagnosed when the criteria for autism or Asperger syndrome are not met.
Autism has a strong genetic basis, although the genetics of autism is complex and it is unclear whether ASD is explained more by rare mutations, or rare combinations of common genetic variants. In rare cases, autism is strongly associated with agents that cause birth defects Controversies around other proposed environmental causes, such as heavy metals, pesticides and childhood vaccines; .. The vaccine hypotheses are biologically plausible and the lack of convincing scientific evidence The incidence of autism is about 1 to 2 per thousand people worldwide, but the Centers for Disease Control and Prevention (CDC) reports about 9 per thousand children in the United States are diagnosed with ASDThe number of people with autism has risen dramatically since. 1980, partly because of changes in diagnostic practice, the question of whether actual prevalence has increased is unresolved .
Parents usually notice signs in the first two years of life of their child.The signs develop gradually, but some autistic children first develop more normally, then relate.Early intervention can help cognitive behavioral or autistic children to develop skills of self-care, social and communicative. Although there is no known cure, There have been case reports of children who have recovered.Not many children with autism live independently after reaching adulthood, although some success. An autistic culture has developed, with some people seeking a cure and others believing autism must be accepted as a difference and not treated as a disorder .
