In this episode, Dr. Jockers sits down with neurologist and bestselling author Dr. David Perlmutter to explore microglia, the brain's immune cells, and the role they may play in protecting the brain from cognitive decline. You'll learn what can shift these cells from a supportive state toward one that promotes neuroinflammation. Discover why your metabolic health and brain health are deeply connected. Dr. Perlmutter explains how blood sugar, insulin resistance, gut health, and chronic inflammation can influence microglial function and why addressing these factors may be important long before memory problems appear. You'll also hear practical ways to support your brain through exercise, nutrition, sleep, metabolic flexibility, and other daily habits. Dr. Perlmutter shares why protecting your brain isn't just about what happens later in life—and how the choices you make today can help shape your cognitive future.
