How to Change Your Brain's Destiny Before It's Too Late | Dr. David Perlmutter – EP 809
Summary
Dr. David Perlmutter joins John R. Miles to discuss his book *Brain Defenders*, explaining how microglia, the brain’s immune cells, can shift from protective to destructive based on metabolic health. They explore how lifestyle factors like diet, sleep, exercise, and oral hygiene influence these cells, impacting risks for Alzheimer’s, PTSD, and other neurodegenerative conditions. Perlmutter argues that daily choices shape brain destiny long before symptoms appear, offering actionable steps to maintain cognitive health and prevent decline.
