WHAT IS ASD?
What is ASD (Autism Spectrum Disorder)? It is a pervasive developmental disorder that may begin at birth or within the first two-and-half years of child’s life. Most children diagnosed with ASD are perfectly normal in their appearance, which makes early detection more challenging when compared to any disorders with physical manifestations. A child with ASD, is a child who spends his/her time being engaged in puzzling and somewhat disturbing behaviors which are markedly different of those of typical children.
Scientists aren’t certain about what causes ASD, but it’s likely that both genetics and environment play a role. Researchers have identified a number of genes associated with the disorder. Studies of people with ASD have found irregularities in several regions of the brain. Other studies suggest that people with ASD have abnormal levels of serotonin or other neurotransmitters in the brain. These abnormalities suggest that ASD could result from the disruption of normal brain development early in fetal development caused by defects in genes that control brain growth and that regulate how brain cells communicate with each other, possibly due to the influence of environmental factors on gene function. While these findings are intriguing, they are preliminary and require further study. The theory that parental practices are responsible for ASD has long been disproved.
