Study: Up to 98% of NFL Players May Have CTE
Researchers found CTE in 93% of donated brains and said the true prevalence among former players likely falls between 24.5% and 97.7%.
- On Tuesday, a study published in the British Medical Journal estimated at least 25% of former National Football League players who died between 2016 and 2021 suffered from chronic traumatic encephalopathy , a degenerative brain disease.
- Chronic traumatic encephalopathy can only be diagnosed through post-mortem autopsy; researchers calculated the 25% figure by analyzing brain donations and death records for 878 former players who died during that six-year study period.
- Dr. Daniel Daneshvar, the study's lead author at Mass General Brigham, reported that CTE severity at death significantly correlates with dementia; roughly 61.3% of brain donors with the disease met clinical criteria for dementia before their deaths.
- Daneshvar urged teams at all levels—youth, high school, and college—to reduce cumulative head impacts during practice, arguing that nearly 70% of impacts occur in practice rather than games.
- While an NFL spokesperson stated the league "continuously strives to make the game of football safer," researchers suggest the actual CTE prevalence could range from 24.5% to 97.7%, indicating further studies are needed.

When the NFL season kicks off next month, millions of Americans will gather around their televisions to watch athletes of comic book proportions crash into each other at breathtaking speeds. Inevitably, those players’ heads will smash into each other, leaving them dazed on the field. And according to a major new study, these repeated head-on collisions may eventually lead to a degenerative brain disease for many — if not most — of the players lo…
