The Hidden Brain Toll of Professional Football

A startling 92 percent of deceased NFL players studied were found to have CTE, a degenerative brain disease. In contrast, the condition is almost non-existent in the general public.

Researchers examined hundreds of brains from former football players and discovered that the vast majority showed clear signs of severe brain damage. For over a decade, the league officially denied that the repetitive head impacts inherent in the sport could cause such long-term neurological harm. Today, the focus has shifted toward better understanding how these accumulated hits permanently alter a player's biology. This data has fundamentally changed how we view the safety of contact sports.
