Podcast Highlights

The Invincible Brain: Rethinking Alzheimer's and Protecting Cognitive Health with Dr. Majid Fotuhi Dr. Ben Weitz interviews neurologist and author Dr. Majid Fotuhi about how the brain can stay resilient with age through neuroplasticity and lifestyle-based interventions. They discuss exercise, sleep, diet, stress reduction, and brain training as key pillars for supporting cognition, and why challenging, enjoyable activities can strengthen the brain. Dr. Fotuhi explains that late-life cognitive decline is often labeled as Alzheimer's even though multiple treatable factors may be involved, and he shares clinical results showing cognitive improvement and increased hippocampal volume after a multidisciplinary program. The episode also addresses the limitations of an amyloid-only focus, the modest effects of anti-amyloid drugs, and the importance of personalized evaluation using appropriate testing. 00:00 Rational Wellness Podcast Intro + What You'll Learn Today 00:56 Meet Dr. Majid Fotuhi & The "Invincible Brain" Concept 02:34 Neurogenesis Is Real: Making New Neurons at Any Age 03:32 Exercise for Brain Growth: BDNF, Blood Flow & Mitochondria 05:21 Strength + Cardio: Why Muscle Mass Protects the Aging Brain 06:45 Challenge Your Brain: Novelty, Frustration & Building New Synapses 08:33 Brain Training Apps vs Real-World Hobbies (and What Actually Sticks) 11:54 Why Alzheimer's Is Often Overdiagnosed: The "Soup" of Brain Pathology 16:24 Treat the Treatable: 5 Pillars Program + MRI/Cognitive Improvements 18:45 Amyloid Controversy: Research Scandals, What Amyloid Really Means 23:34 Do Amyloid Drugs Work?
