Restore Youthfulness & Vitality to the Aging Brain & Body | Dr. Tony Wyss-Coray

About this video

Huberman interviews Dr. Tony Wyss-Coray of Stanford about restoring youthfulness to the aging brain and body. Dr. Wyss-Coray describes parabiosis experiments in mice, in which circulation shared with a young animal reactivated brain stem cells, reduced inflammation, increased brain activity and improved memory in old mice. He explains that aging is non-linear, with accelerated phases, and that different organs age at different rates and can be measured. The conversation covers proteins that decline with age, blood factors linked to exercise, and molecules such as klotho. Dr. Wyss-Coray emphasizes moving from correlation to causation through rigorous animal experiments and blinded human trials, and frames the goal as healthspan — maintaining organ function — rather than simply extending lifespan.
