Autism epidemic may be all in the label

A few decades ago, people probably would have said kids like Ryan Massey and Eddie Scheuplein were just odd. Or difficult.
Both boys are bright. But Ryan, 11, is hyper and prone to angry outbursts, sometimes trying to strangle another kid in his class who annoys him. Eddie, 7, has a strange habit of sticking his shirt in his mouth and sucking on it.
Both were diagnosed with a form of autism. And it's partly because of children like them that autism appears to be skyrocketing: In the latest estimate, as many as one in 150 children have some form of this disorder. Groups advocating more research money call autism "the fastest-growing developmental disability in the United States."
