Parents are bombarded with stories that say autism is linked to a smorgasbord of things, from mom's age to air pollution. How do we make sense of this?
Doctors have known about a link between autism and epilepsy since a psychiatrist published the first case study about children with "autistic disturbance" some 70 years ago.

In different laboratories on opposite sides of the U.S., two researchers were waiting.
The June 9, 2011 issue of Neuron featured three groundbreaking studies on autism genetics.
A new approach to studying genetics may permit us to understand what genetic "tweaks" have caused an autism spectrum disorder (ASD) in a specific individual.
