New Study Suggests 3 in 4 Former NFL Players Who Died From 2008 to 2023 Had CTE
Researchers adjusted for brain-donation bias and estimated that 27.2% of the players had dementia during their lifetime.
- On Wednesday, a study published in JAMA Network Open estimated that 74.5% of deceased former NFL players had chronic traumatic encephalopathy , based on records for 2,362 players who died between 2008 and 2023.
- Researchers adjusted for selection bias, noting that families of players with cognitive symptoms were five times more likely to donate brains, correcting the initial 94% observed rate to the 74.5% population estimate.
- Data showed that about 27% of players had dementia, a rate four times higher than in the general population; CTE is found in less than 1% of community-based brain bank donors.
- Responding to the report, the NFL Players Association called the study "critical" to understanding football's health impacts, while the NFL stated it "continuously strives to make the game of football safer" through Guardian Caps.
- Authors advise parents to delay tackle football until high school to limit lifetime head impacts; although CTE can only be diagnosed after death, scientists are researching biological markers to enable earlier detection for living players.
