STUDY: 90 Percent of Former Football Players had CTE


Researchers found chronic traumatic encephalopathy (CTE) in almost 90 percent of former football players’ brains tested during a recent study.

A study in the Journal of the American Medical Association showed that chronic traumatic encephalopathy (CTE) was found in 87 percent of the brains studied. CTE is a brain disease typically seen in people with repetitive brain trauma, such as athletes. CTE causes the release of the Tau protein, which kills brain cells. This typically leads to memory loss, impaired
judgment, and dementia. 110 out of 111 brains of former NFL players studied were found to have CTE. CTE was also found in 48 out of 53 college football players’ brains and three out of 14 high school football players’ brains. The study suggested that CTE may be caused by playing football, however, did not confirm football as the cause of CTE.

This study hits especially close to Arizona. The brain of former Arizona Cardinals’ player, Dave Duerson, was used in the study. Duerson played for the Cardinals from 1991 to 1993, when they were known as the Phoenix Cardinals.
