Drugs and Chemical Substances Cause Autism

Experts seem to grow closer to understanding the causes of autism. Environmental factors thought to play a greater role as a trigger for autism than genetic factors. These environmental factors include exposure to chemicals and drugs.

 
In a study researchers from Stanford University compared the cases of autism in identical twins and not identical twins who share only half of the same gene. Apparently, cases of autism are more common in twins are not identical, so the experts say other factors besides the genetic triggers of autism.

Other research says the mothers who have children with autism are twice as many who take antidepressant drugs a year before their pregnancy compared with mothers whose children healthy. The risk increased considerably, reaching a three-fold, especially if the drug was taken in early pregnancy.

The study, published in the journal Archives of General Psychiatry that mention environmental factors, such as pharmaceuticals, chemicals, or infections, triggers autism in children who are genetically inclined.

"So far there had been allegations of influence of environmental factors, but research is further strengthens the theory that," said Clara Lajonchere, deputy head of the program of Autism Speaks.
