is anyone aware of any current research on concussion or repetitive head injury in kids who participate in contact sports?
Your best best would be to search for info on youth head injuries in American football. I saw an article a few years ago specifically how head trauma from football and then heavy intellectual work in the classroom was furthering brain damage. I'll have a look and see if I can find it.
Here are a few places with info on concussions.. How old are the kids involved? Which sports?
