New study: Environmental factors may increase risks for autism

A new study was announced yesterday by Autism Speaks, the world's largest autism science and advocacy organization,  which suggests that while genetics play a role in autism, environmental factors - like parental age, low birth weight, multiple births, and maternal infections during pregnancy–may increase risks for ASD.

Elizabeth Cohen, senior CNN medical correspondent, joins American Morning today to explain the details of the study and to discuss how researchers reached their conclusions about the development of the disorder.
