A sobering new study reveals that at least one in four former NFL players who passed away between 2016 and 2021 suffered from chronic traumatic encephalopathy, commonly known as CTE. Out of 878 deceased players during that window, 235 donated their brains for research, and a staggering 215 of those samples tested positive for the degenerative disease. Because CTE can only be definitively diagnosed after death, the findings provide a grim snapshot of the long term neurological toll associated with professional football.
Daniel Daneshvar, the study’s lead author and a professor at Harvard Medical School, noted that NFL players experience death from neurodegenerative diseases at roughly four times the rate of the general population. While much of the public focus remains on the professional league, Daneshvar emphasized that the damage often begins long before a player reaches the pros. He explained that the bulk of repetitive head impacts actually occur during youth, high school, and collegiate play, creating a cumulative effect that increases the risk of dementia and other cognitive declines later in life.
In response to the data, an NFL spokesperson stated that the league continues to strive for greater safety through strategies designed to reduce concussions and head impacts. The organization highlighted its commitment to providing physical and mental health resources for its community and encouraged former players to seek medical treatment if they have concerns about their wellbeing. This comes years after a landmark 2016 settlement involving thousands of retired players over concussion related lawsuits.
To mitigate future risks, researchers are calling for systemic changes across all levels of organized football rather than just focusing on game day regulations. Since nearly seventy percent of head impacts happen during practice sessions, experts suggest that limiting contact drills in high schools and youth leagues could substantially lower the lifetime burden of brain trauma. By propagating rules similar to those already adopted by some colleges and professional teams, advocates believe athletes can be better protected without altering a single minute of actual competition.
