A new population-based cross-sectional study published Wednesday in the Journal of the American Medical Association estimates that nearly 75% of former NFL players had chronic traumatic encephalopathy (CTE) at the time of their death.
The research accounted for brain donation registry bias, a common limitation in previous studies that relied on self-selected brain donations from families concerned about cognitive decline.
The findings, reported by contributing writer Andy Backstrom, underscore the long-term neurological risks associated with professional football careers.
