Dr. Ann McKee, director of BU’s CTE Center and chief of neuropathology at the Boston VA, published a new study in The Journal of the American Medical Association which shows a direct link between chronic traumatic encephalopathy (C.T.E.) and repeated blows to the head.
Of the 111 players in the study, 110 of them were found to have C.T.E., which causes memory loss, confusion, depression and dementia. The N.F.L. has slowly began to accept the presence of C.T.E. in players, but are still hesitant to change the rules of the game to benefit the health of its players. Commenting on her study McKee said, “It is no longer debatable whether or not there is a problem in football — there is a problem.”
