Austim Speaks's Geraldine Dawson and author Glen Finland respond to new study that suggests significant increase in children diagnosed with autism

There's a new debate building about the cause of autism, fueled by new numbers from a CDC report showing a significant increase in the number of kids diagnosed with autism spectrum disorder.

The numbers are staggering: The latest report shows diagnoses are up 80% in the past decade. In 2000 and 2003, about one in 150 children were diagnosed with autism. The latest data suggests 1 in 88 children have autism.

Is there a real cause for concern here that the threat of autism is growing? Or are the diagnoses criteria becoming broader?

This morning on "Starting Point" Austim Speaks's chief scientific officer Geraldine Dawson, Ph.D. talks about the new study. She's joined by Glen Finland, author of "Next Stop" which chronicles her experience raising her son David, who has autism.
