Women who take prenatal vitamins and eat cereal supplemented with folic acid in the early months of pregnancy are less likely to have children with autism compared with women who consume less folate, suggests preliminary data from a survey presented today at the Society for Neuroscience conference.

A new genetic study is lending support to the notion that immune system abnormalities and some forms of autism go hand in hand.

Having the flu during pregnancy can be unpleasant and exhausting. But can it affect fetal brain development and cause autism-like disorders? Intriguing new research says yes ― at least in mice.
