Genes are answering questions for autism families

Many parents of autistic children were included in a recent 19-country survey of 1,200 families who wanted to take a closer look at how genes might be involved in the autism of their children.

Autism, which often results in social awkwardness to a near-complete failure to communicate with the outside world, is estimated to affect nearly 1 in 150 kids just in the U.S. alone (in some form; mild or severe).

Is there really an "autism epidemic" that has hit not only the U.S. but many western societies? Some experts say that society is now looking much more harder for autism and so it is being diagnosed in more numbers. What are the causes, regardless of increasing amounts of individual diagnosis? That is the question.
