Study reveals widespread brain disease among deceased NFL players
A new analysis suggests that three out of four former National Football League players who died between 2008 and 2023 likely had chronic traumatic encephalopathy (CTE) at the time of their death. The findings underscore the long-term neurological risks associated with the sport.

Researchers examining brain tissue from deceased former NFL players have reached a sobering conclusion about the prevalence of chronic traumatic encephalopathy, a degenerative brain condition linked to repeated head impacts. The latest estimate indicates that approximately 75 per cent of players who passed away during the 15-year study period showed evidence of CTE pathology in their brains.
CTE is a progressive neurodegenerative disease that has been associated with memory loss, confusion, impaired judgement, aggression, and depression. While the condition can only be definitively diagnosed through post-mortem examination of brain tissue, the new findings suggest the disease may be far more prevalent among professional football players than previously understood.
The research adds to growing scientific evidence linking repeated traumatic brain injuries sustained during athletic careers to long-term neurological decline. Medical experts have expressed concerns about the cumulative effects of subconcussive hits and full concussions that players experience throughout their professional careers.
The findings come amid heightened scrutiny of player safety protocols in professional football and renewed debate over whether current injury prevention and management standards adequately protect athletes' long-term health. The results may prompt further investigation into the mechanisms of CTE development and consideration of additional preventative measures across the sport.
