Study finds CTE rates in deceased NFL players higher than earlier estimates

A new study has found that at least one in four former NFL players who died between 2016 and 2021 showed signs of chronic traumatic encephalopathy (CTE), a degenerative brain disease. Researchers believe the actual prevalence could be significantly higher than the recorded figure. The findings add to growing evidence linking repeated head trauma from American football to long-term neurological damage. The study raises fresh concerns about player safety and the long-term health consequences of professional football careers.
