1 in 4 former NFL players who died from 2016 to 2021 had CTE, study estimates

Researchers said the true rate could be higher, and more than 90% of Stage IV cases also had dementia.

  • 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.
