Age of parents linked to increased risk of autism

A new study says that older women are more likely to have autistic children.

Older mothers are more likely to have autistic children, a new study says. The journal Autism Research found that women over 40 were 50% more likely to have an autistic child. What about older fathers? Their age seems to play a greater role when mothers are much younger. Women under 25 who had children with men over 40 were twice as likely to have autistic children compared with fathers in their 20s. How should parents assess autism risk? Will older men and women think twice about having children?
