Older Parents Increase Autism Risk

NEW YORK -- Children born to a parent over age 35 are at greater risk for developing an autism spectrum disorder -- but the risk is the same whether just one or both parents are older, according to a new study of Danish families.
"Parental age doesn't appear to be synergistic. That is having an older mom and an older dad doesn't increase risk more than having one or the other," said Marissa King, a professor at the Yale School of Management, who was not involved in the study.
