White Matter Hyperintensities and Reversibility

Up to 70% of dementia may be preventable, so why aren’t more people talking about what actually drives cognitive decline? In this episode, I’m with Dr. Tommy Wood, neuroscientist and author of “The Stimulated Mind,” to explore the lifestyle levers that protect your brain across a lifetime. Learn how white matter hyperintensities develop and whether they can reverse, what MCTs and ketones actually do for a glucose-starved brain, and why social connection may be the most underrated variable in cognitive aging. What is the one change you could make today that would most protect your brain tomorrow?
