The New York Times recently investigated the long term affect of concussions suffered by NFL players, focusing on former NFL players and their cognitive behavior. Utilizing a recent study by the University of Michigan’s Institute for Social Research that included interviews of 1,063 former NFL players, the Times reported that 6.1 percent of former players aged 50 and older had received dementia-related diagnosis. That is five times the national average of 1.2 percent.
