Inside every one of your cells, a powerful self-cleaning process is working to protect your brain from Alzheimer’s and dementia — and most people have never heard of it. It’s called autophagy, and in 2016, it won the Nobel Prize in Physiology or Medicine. In this video, I’ll break down exactly what autophagy is, how it protects your neurons from the protein buildup linked to Alzheimer’s disease, Parkinson’s, and Huntington’s — and the 4 science-backed habits that keep this process working as you age.
In this video you’ll learn:
✅What autophagy is and how it works at the cellular level (macroautophagy, microautophagy, and CMA)
✅Why neurons are uniquely vulnerable to waste buildup — and what that means for dementia prevention
✅How sleep and your circadian rhythm regulate brain autophagy
✅The Nobel Prize-winning discovery by Yoshinori Ohsumi that changed how we understand healthy aging
✅How fasting, exercise, and specific foods can activate autophagy
✅What the TAME trial and Metformin may mean for the future of longevity science
If you care about brain health, cognitive longevity, or simply want to understand the science behind how to prevent Alzheimer’s — this video is for you.⏱️
