Older fathers may be linked to child autism

Older Fathers Linked to Child AutismThe Empowered Patient is a regular feature from CNN Senior Medical News Correspondent Elizabeth Cohen that helps put you in the driver’s seat when it comes to health care.

Women aren’t the only ones whose biological clocks are ticking: A new study on the genetics of autism finds the sperm of older men may be to blame for many cases of the disorder.

The study, done by researchers in Iceland, indicates that as many as 20-30% of cases of autism and schizophrenia may be linked to the father’s advanced age.  Unlike findings on disorders such as Down Syndrome, this study found that the age of the mother made no difference.

“This is really a paradigm shift,” said Dr. Jamie Grifo, program director of the New York University Fertility Center.

Traditionally, women have borne the brunt of concerns about having a healthy child as they age, while many men have assumed their sperm were no different at 80 than at 20.
