RHR: Preserving Cognitive Function As You Age, with Tommy Wood

In this episode of Revolution Health Radio, Chris Kresser is joined by neuroscientist and physician Dr. Tommy Wood to explore how cognitive function can be preserved—and even enhanced—as we age. Dr. Wood challenges outdated ideas about inevitable cognitive decline and reframes dementia as a largely preventable, multifactorial condition. The conversation covers the historical roots of Alzheimer's disease, why "one-size-fits-all" drug approaches have failed, and how lifestyle, environment, and brain use interact to shape long-term brain health. Dr. Wood introduces his 3S model of brain health, explains why retirement may be a mismatch for brain biology, and breaks down the roles of exercise, nutrition, sleep, and cognitively demanding activities in building lifelong cognitive resilience. In this episode we discuss: The history of Alzheimer's disease and what it reveals about modern dementia research Why most late-onset dementia is heterogeneous and largely preventable The Lancet Commission findings on modifiable dementia risk factors Dr. Wood's 3S Model of Brain Health Why retirement often accelerates cognitive decline—and how to redesign later life for brain health The difference between "brain training" and truly brain-stimulating activities How complex, coordinated physical activities outperform simple exercise for cognitive resilience Key nutrients for long-term cognitive health, including B vitamins, omega-3s, vitamin D, iron, and polyphenols What really matters most for sleep when it comes to protecting the brain Show notes: The Stimulated Mind by Dr. Tommy Wood Better Brain Fitness podcast Better Brain Fitness Substack Better Brain personalized brain check-ups and expert coaching "Dementia prevention, intervention, and care: 2024 report of the Lancet standing Commission" by Livingston, G., et al.
