Today's Topic

Recent reports of early dementia and other neurological problems in professional football and hockey players have raised concerns about the long-term impact of head injuries suffered in the course of play. Are college and high school athletes also at risk? What does the latest research tell us about how sports concussions affect the brain? And what if anything can be done to make contact sports safer?

Join us for a live chat at 3 p.m. EDT on Thursday, 6 September, on this page. You can leave your questions in the comment box below before the chat starts. The full text of the chat will be archived on this page.
