Episode Details

Marshawn Kneeland, former Dallas Cowboys defensive end who died by suicide in August, was found to have stage one CTE — a brain disease tied to repeated head trauma — in a post-mortem study. While not the direct cause of his death, the diagnosis underscores the growing epidemic of CTE in athletes, even those playing with modern safety measures. Researchers note nearly half of deceased athletes under 30 show CTE, highlighting the urgent need for systemic change. The Concussion & CTE Foundation is calling for broader efforts to reduce head impacts, not just manage concussions, and is working toward live diagnosis — a breakthrough still years away — thanks to families who donate brains for science.
