Study estimates 75% of NFL players who died over 15-year span may have had CTE

A new study published Wednesday indicates that approximately 75% of professional football players who died over a 15-year span exhibited signs of chronic traumatic encephalopathy, or CTE. This finding suggests that nearly 3 in 4 former NFL players had the condition at the time of their death. This represents the highest estimation of CTE prevalence among professional football players recorded to date, highlighting a significant health concern within the league's former athlete population.
