A study published Tuesday in the British Medical Journal found that at least 25 percent of former NFL players who died between 2016 and 2021 had chronic traumatic encephalopathy (CTE), a degenerative brain disease linked to repeated head impacts. The study examined 878 players who appeared in at least one NFL game during that period and found that 91 to 93 percent of the 235 brains that were donated and examined had CTE, though the overall prevalence could be as high as 97 percent when accounting for unexamined brains.

Not yet confirmed against a primary source
- Confirm whether 235 or 338 player brains were examined in the study. Bu.edu states '338 who had donated their brains for evaluation or research' while other outlets state '235.' Verify against the published study or institutional statements from Boston University and Mass General Brigham.
- Confirm the exact percentage of donated brains diagnosed with CTE: aol.com reports 93 percent, newstribune.com reports 91.5 percent, timesofindia.indiatimes.com reports 91 percent. Verify against the British Medical Journal publication.
- Confirm whether the study examined 878 players (most outlets) or 1,712 players total (bu.edu). Bu.edu's framing suggests 878 is a subset. Verify the distinction against the published study methodology.

The research utilized a total cohort of 1,712 player deaths to calculate that at least 24.5% of the total, or roughly one in four, likely had the disease. · 2026-08-26
