Autism has a strong genetic basis, although the genetics of autism are complex and it is unclear whether ASD is explained more by rare 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 1,000people worldwide; however, the Centers for Disease Control and Prevention (CDC) reports an approximate of 9 per 1,000 children in the United States are diagnosed with ASD. 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 usually notice signs in the first two years of their child's life. The signs usually develop gradually, but some autistic children first develop more normally and then regress.Although there is no known cure, early behavioral or cognitive intervention can help autistic children gain self-care, social, and communication skills.Not many children with autism live independently after reaching adulthood, though some become successful. An autistic culture has developed, with some individuals seeking a cure and others believing autism should be accepted as a difference and not treated as a disorder.
Myths about autism
A person with autism feels love, happiness, sadness and pain just like everyone else. Just because some of them may not express their feelings in the same way others do, does not mean at all that they do not have feelings - THEY DO!! It is crucial that the Myth - Autistic people have no feelings - is destroyed. The myth is a result of ignorance, not some conspiracy. Therefore, it is important that you educate people who carry this myth in a helpful and informative way.
Not all people with autism have an incredible gift or savantism for numbers or music. People with autism are ordinary people... with autism.
