New research reveals that professional football players face a dramatically higher risk of dying from brain diseases like dementia and Parkinson's. A study of 19,824 NFL players from 1960 to 2019 found they were nearly four times more likely to die from neurodegenerative conditions than the general population.
The Research
A team from Mass General Brigham, Boston University, and the Concussion & CTE Foundation analyzed health records spanning six decades. The results, published in eClinicalMedicine, show that while NFL players had lower overall death rates—likely due to their elite fitness and health advantages—their neurodegenerative mortality was 3.94 times higher. Specifically, dementia death rates were 3.8 times higher, and Parkinson's disease rates were 3.88 times higher.
The study introduces a concept called the "STARS effect" (Selection Through Athletic Resilience Survivor), which explains that NFL players are genetically, medically, and behaviorally healthier than the average person. This makes the elevated neurodegenerative death rate even more striking, as it suggests the brain damage from repeated head impacts overrides these natural protections. Among players who died before age 60, the neurodegenerative death rate was a staggering 12 times higher than age-matched peers. Additionally, players with careers longer than five seasons had double the risk compared to those with shorter careers, indicating a clear dose-response relationship.
Why It Matters for Your Brain
While most people won't play professional football, this study underscores how repeated head impacts—even sub-concussive ones—can accumulate to harm brain health over time. The findings align with broader research on traumatic brain injury and chronic traumatic encephalopathy (CTE). For anyone engaged in contact sports or activities with head impact risk, awareness is key. Protecting your brain means recognizing that even mild, repetitive impacts may have long-term consequences.
What You Can Do
- Protect your head: Wear appropriate safety gear in sports, and avoid activities with high head impact risk when possible.
- Monitor symptoms: After any head injury, watch for cognitive changes like memory lapses, confusion, or mood shifts, and seek medical evaluation.
- Support brain health: Regular aerobic exercise, a balanced diet rich in omega-3s, and cognitive stimulation (like puzzles or learning new skills) may build resilience.
