In this episode, Dr. David Perlmutter makes the case that the true driver of neurodegeneration isn&#39;t plaque at all. It&#39;s your own brain&#39;s immune cells turning against you.For decades the field blamed beta-amyloid protein for Alzheimer&#39;s. Perlmutter walks through a mechanism reshaping the science: the dysregulation of microglia, the immune cells that can either protect your brain or actively destroy it depending on how you live.We dig into the chilling Parkinson&#39;s case where contaminated heroin froze patients like statues and revealed immune cells still attacking the brain decades later, why the same self-perpetuating inflammation shows up in CTE, long COVID, and PTSD, how your gut and blood sugar flip these cells into attack mode, the 14 metabolic risk factors that could prevent up to half of dementia cases, and the MIT-pioneered 40 Hz light and sound therapy that slowed cognitive decline and stabilized brain volume in human trials.<a href="https://www.youtube.com/watch?v=2Az4a6CKI_4">00:00</a> - Introduction<a href="https://www.youtube.com/watch?v=2Az4a6CKI_4&t=22s">00:22</a> - The Plaque Theory and Why It&#39;s Incomplete<a href="https://www.youtube.com/watch?v=2Az4a6CKI_4&t=32s">00:32</a> - Meet the Microglia: Your Brain&#39;s Immune System<a href="https://www.youtube.com/watch?v=2Az4a6CKI_4&t=57s">00:57</a> - Supportive vs. Threatening: The M1/M2 Switch<a href="https://www.youtube.com/watch?v=2Az4a6CKI_4&t=103s">01:43</a> - Why This Underlies Nearly Every Neurodegenerative Disease<a href="https://www.youtube.com/watch?v=2Az4a6CKI_4&t=155s">02:35</a> - The Frozen Patients: A Parkinson&#39;s
