Study estimates 75% of deceased NFL players had CTE
A study published Wednesday estimates that about 75% of former NFL players who died over a 15-year span had signs of chronic traumatic encephalopathy, or CTE.[1, 2, 4] The research, published in JAMA Network Open, examined the estimated prevalence of CTE among 2,362 players who died between 2008 and 2023.[2] It is the highest estimation to date, according to NBC News.[4]
The study was conducted by a Boston-based team; CBS News identified it as coming from Boston University.[2, 3] Christopher Nowinski, CEO of the Concussion & CTE Foundation, said CTE is an entirely preventable disease.[1]
