Rain Man may have turned public focus to autism but scientists have been scrutinizing it for years. Following decades of research, significant advances have confirmed that biology is behind this brain disorder that is marked by deficits in the higher order cognitive abilities involved in social, communication and problem-solving behavior. New findings on the genetic and anatomical roots of autism are helping researchers piece together how the disorder evolves, which could lead to new treatments.
