Because a steady stream of research is also beginning to suggest that identifying and treating high-risk individuals may help to ameliorate course and potentially prevent the onset of. A new study found that activation in pregnant mice of a particular immune response similar to what may occur with certain viral infections during pregnancy alters the brain structure of the mouse offspring and causes behavioral changes reminiscent of those observed in humans with autism.

For example a 2010 study of more than 10000 people with autism in Denmark found a threefold increase in the risk of autism among children whose mothers were hospitalized with viral infections during the first trimester. Prenatal exposure to rubella or cytomegalovirus activates the mothers immune response and may greatly increase the risk for autism in mice.

These structural abnormalities may cause significant alterations in oxygen and nutrients delivered to the fetus causing abnormalities in the overall development of the fetus including the brain. Evidence suggests that normal pregnancy may be accompanied by changes in the immune response that may in part account for the successful growth and delivery of the fetus hemi-allograft A subtle shift from the response of Th1 cellular immunity CD4 lymphocytes to a proportional increase in the Th2 humoral immunity CD4 response can be.
