Do repeated “bell ringers” and repetitive, sub-concussive hits add up over time? In this episode of Learning From Leaders, host Lili Clark sits down with Dr. Jeff Schaffert, assistant professor in UT Southwestern Medical Center’s Department of Psychiatry, to explore the evolving science of brain health in athletes. Fresh off receiving The Cary Council’s $50,000 early-stage research grant, Dr. Schaffert shares how the pilot study he's leading combines blood-based biomarkers, advanced neuroimaging, and cognitive testing to look for early, often invisible signs of cognitive decline in former collegiate football players.
You’ll hear why this research matters beyond the NFL and how researchers are trying to better understand neurodegenerative risk. Dr. Schaffert also breaks down what leadership looks like in the lab and explains what researchers hope to learn from early signals such as neuroinflammation and white matter changes.
The conversation also zooms out into practical, balanced guidance for families weighing the benefits of sports, plus everyday brain-health habits that can reduce dementia risk over time. This episode tackles the big question about brain health in football and offers clarity, nuance, and a grounded look at what we know and what scientists are still working to understand.
