Autism Spectrum Disorders
Autism is a disorder of neural development characterized by impaired social interaction and Communication, and by restricted and repetitive behaviour. The signs begin before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organizer, but how it occurs is not well understood. Autism has a strong genetic basis, although the genetics of autism is too complex to draw specific conclusions. In some cases, autism is associated with agents that cause birth defects. Controversies surround over the environmental causes like heavy metals, pesticides, childhood vaccines, etc. Though there is no convincing scientific evidence. According to br. Howlin et al. , not many children with autism live independently though some become successful.
