National Football League players face a neurodegenerative mortality rate four times higher than the general population, according to a cohort study of nearly 20,000 players published in eClinicalMedicine. Research conducted by Mass General Brigham, Boston University, and the Concussion & CTE Foundation confirms that while NFL players often show lower all-cause mortality, they suffer from significantly elevated rates of dementia and Parkinson’s disease.
How does professional football affect brain health?
The study, which examined health records of 19,824 NFL players who competed between 1960 and 2019, identifies a clear link between repetitive head impacts and neurodegenerative disease. Even when accounting for other risk factors, players were three times more likely to die from these conditions than the general population. According to Daniel Daneshvar of Harvard Medical School and Spaulding Rehabilitation Hospital, this is the clearest population-level evidence we have ever had that NFL players die from neurodegenerative diseases at measurably higher rates.
The study identified a “dose-response” relationship: players with longer careers of five seasons or more had nearly double the risk of neurodegenerative death compared to those who played for one to four seasons.
Why do players show lower overall mortality rates?
Despite the elevated risk of brain disease, NFL players generally have lower all-cause mortality than the public, including fewer deaths from cancer, cardiovascular disease, and suicide. Researchers call this the “Selection Through Athletic Resilience Survivor” (STARS) effect. According to the study, the same traits that lead to professional athletic success—such as exceptional physical and cognitive performance, resilience, self-discipline, and lower rates of smoking and serious early illnesses and injuries—contribute to longer overall survival.
What is the impact on younger former players?
The statistical disparity is most dramatic among younger cohorts. Players who died before age 60 experienced more than 12-fold increased rates of neurodegenerative death compared to the general population. Jesse Mez, associate director of the Boston University Alzheimer’s Disease Research Center, notes that a fourfold increase in dementia rates from a presumed environmental cause is immense, with brain bank studies pointing to chronic traumatic encephalopathy (CTE) as the primary explanation.
Former players concerned about cognitive health should consult specialists. Many symptoms resembling neurodegenerative disease are treatable. Resources such as The Trust (Powered by the NFLPA), the NFLPA’s Professional Athletes Foundation, and the Concussion & CTE Foundation HelpLine are available for guidance and referrals.
Frequently Asked Questions
Is neurodegenerative disease risk higher for all NFL players?
The study found a consistent increase in neurodegenerative mortality across the cohort. However, the risk is higher for those with longer careers, specifically those playing five or more seasons.
How does this compare to other environmental hazards?
According to Jesse Mez, the fourfold increase in dementia rates among players is more severe than the neurological consequences of heavy lead exposure, which is linked to a two to three times greater rate of dementia.
Why are NFL players generally healthier than the general population?
The STARS effect suggests that professional athletes possess unique genetic, medical, and behavioral advantages, including higher educational attainment and better access to healthcare, which contribute to longer overall survival.
