Chemical Environment Influence the Incidence of Childhood Autism

Study on etiology of childhood autism has always been a challenge for medical research. More and more researchers in this field agreed that autism is a biologically based disease, while genetic or gene abnormality may be the main reason of childhood autism Nowadays, most studies of autism have linked the etiology to genetics, but simple genetic etiology is difficult to explain the complexity and diversity of autism in children. Interestingly, many recent studies have indicated that the chemical environmental factors may be involved in the development of childhood autism. In many cases, genes or chemical environment alone may not be sufficient to cause autism, interactions of both them may increase prevalence of autism in children In order to clear the role of chemical environments in the etiology of autism, this article gives a comprehensive analysis in effects of chemical factors, genetic factors alone or both in combination on childhood autism, which may be able to provide new strategies for prevention and treatment of the disease.
