Using a battery of imaging and cognitive tests, Johns Hopkins specialists have gathered evidence of accumulated brain damage that may be linked to specific memory deficits experienced by former National Football League players decades after retirement.
The study, results of which were published in the February 2015 issue ofNeurobiology of Disease, included nine former NFL players ranging in age from 57 to 74 years. Each had played a variety of team positions and had a wide range of self-reported, historical concussions, varying from none for a running back to 40 for a defensive tackle. Nine age-matched, healthy controls with no reason to suspect they had brain injuries were also recruited, according to a press release.
