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 Wood challenges outdated ideas about inevitable cognitive decline and reframes dementia as a largely preventable, multifactorial condition.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.
