  • •The study combined data from brain donations and death records to reduce bias.

A Boston University study published on October 29, 2026, found that 74.5% of 2,362 deceased NFL players from 2008 to 2023 likely had chronic traumatic encephalopathy (CTE), a neurodegenerative disease linked to repeated head impacts. The study aimed to eliminate selection bias by combining data from brain donations and National Death Index records. Nearly 94% of donated brains showed CTE, leading researchers to estimate the overall prevalence at 74.5%. Rams players expressed awareness of CTE risks, with defensive tackle Aaron Donald acknowledging its reality. The findings emphasize the importance of understanding CTE's prevalence among living players to prepare the medical community for potential cases.
