How To Make Your Brain Invincible With Dr. Majid Fotuhi, MD, PhD

Most of us assume that losing our memory is just an unavoidable part of getting older, but there is a big difference between what is common and what is actually normal. I am joined by Dr. Majid Fotuhi, a neuroscientist, physician, and the author of The Invincible Brain, to find out how we can actually protect our minds. He describes Alzheimer's as largely a multifactorial condition, meaning it is driven by things we can treat, like obesity, sleep apnea, and chronic stress, rather than just being a random buildup of amyloid plaques and tau tangles. Dr. Fotuhi uses the analogy of a garden: the brain needs oxygen, nutrients, and a "rinsing" through the glymphatic system during deep sleep to stay healthy. We talk about his five main pillars for brain health: avoiding highly processed foods, staying fit with both cardio and weights, getting 7 to 8 hours of sleep, maintaining a growth mindset, and learning complex new skills like ballroom dancing. These habits do more than make you feel better; they can physically grow your hippocampus and build cognitive resilience. This lifestyle shift works much better than just relying on supplements. Here are the details of our conversation:
