Brain damage to football players

It is beginning to appear that a series of even relatively minor bumps to the head--those not strong enough to cause concussions--can lead to serious brain damage. Autopsy results on football players as young as 18 are finding remarkable accumulations of tau, an abnormal protein found in Alzheimer's patients. Quoted in the New Yorker, researcher Ann McKee said "You don't see tau like this in an eighteen-year-old. You don't see tau like this in a fifty-year-old." The New York Times reported today on the topic as well.
