Most conversations about dementia start too late — after the diagnosis, after the decline. Dr. Tommy Wood prefers to start decades earlier. The physician and University of Washington neuroscience researcher joined Sean Kelly on the Digital Social Hour to explain what actually drives long-term brain health, and why the habits that protect cognition late in life begin with how we live right now.
Across seventy minutes, the discussion moves from why dementia rates are projected to rise as lifespans extend, to how short-form content is reshaping attention, to what Formula 1 drivers do to stay sharp under extreme pressure. It is practical, evidence-driven, and refreshingly free of quick fixes.
About Dr. Tommy Wood
Dr. Tommy Wood is a physician-scientist whose research at the University of Washington spans pediatrics and neuroscience, with a focus on brain health, cognitive performance, and how lifestyle shapes the aging mind. He has become a trusted public voice for translating brain science into plain language, including the thinking behind The Stimulated Mind, which opens this episode.
Wood also works at the sharp end of human performance, consulting with elite competitors — including Formula 1 drivers — on focus, recovery, and decision-making under pressure. That mix of laboratory science and real-world application is what he brings to the conversation: less hype, more evidence, and a clear view of what the research does and does not support.
What Dr. Tommy Wood and Sean Kelly Talked About
- Why Dr. Tommy Wood expects dementia rates to keep rising as lifespans extend
- How short-form content and constant multitasking are reshaping attention spans, in his analysis
- Why stress is not always the enemy — and how reframing pressure can improve performance
- What Formula 1 drivers can teach the rest of us about focus and recovery
- The nutrition habits he says matter most for the brain, from omega-3s to creatine
- What the research he cites suggests about coffee, alcohol, and APOE4-related dementia risk
- Why education, hobbies, and lifelong skill-building help protect cognitive function
- How sleep, exercise, and recovery work together to shape daily brain performance
Why This Conversation Matters
Dementia touches nearly every family, yet most of what circulates about prevention is either fear or folklore. This episode is a useful corrective: a working neuroscientist walking through what he sees in the evidence on stress, sleep, nutrition, and attention — and what each of us can still control. Few conversations on the Digital Social Hour are this immediately practical.
