A study ordered by the National Football League (NFL) has uncovered critical data about the incidence of memory problems and dementia such as Alzheimer’s disease among NFL players that the league must now face head-on. The findings show that memory-related diseases appear to be significantly more common among NFL players, including a 19-fold higher rate among men ages 30 through 49.

This is not the first time research has shown a relationship between playing football and the development of memory problems and dementia, although it is the first time the NFL has asked for a study to be done. A 2005 study conducted at the University of North Carolina, Chapel Hill, for example, analyzed data from more than 2,550 retired professional football players. Sixty-one percent of them had experienced at least one concussion during their career, and 24 percent had had three or more. The researchers found an earlier onset of Alzheimer’s disease among these men than the general male population, and concluded that dementia-related syndromes may be initiated by concussions in professional football players.

The current study was conducted by the University of Michigan’s Institute for Social Research at the request of the NFL. A total of 1,063 retired NFL players completed the survey given by the Michigan researchers. Among the questions asked of the players was whether they had ever been diagnosed with memory problems, dementia, or Alzheimer’s disease. A total of 6.1 percent of players age 50 and older had been diagnosed with a dementia-related condition, which is five times greater than the national average of 1.2 percent. Younger players (30 to 49 years) had a rate of 1.9 percent, which is 19 times that of the national average of 0.1 percent.

The results of this study send out critical signals to football at high school and college levels, where coaches and administrators typically follow the cues from the NFL concerning safety issues. Unfortunately, concussions are common among school-age players, with hundreds occurring each week. According to a study conducted by Ohio State University and published in August 2009, 11.6 percent of the injuries suffered by high school students who play sports are concussions. A total of 13,755 injuries were reported during the 2005 through 2008 academic years, with football players experiencing the highest rate of recurrent injuries.
