re: First case reported of "CTE" without history of head trauma

That is the changes in the brain that have been seen in all the football players that had the mental problems, suicide etc. Until now we have said, see this evidence of brain damage is because all of the concussions and smaller hits that the football players received.

This throws a curveball. This person has the same changes in their brain as the football players but he had no known history of head trauma.
