The truth about cognitive decline and what you can do about it | Tommy Wood, M.D., Ph.D.

Episode 645 Published 1 month, 1 week ago
Description

“It should be possible to maintain stable cognitive function into your eighth and ninth decades. But we don't really internalize that. We expect decline, and because we expect decline, we're less likely to engage in those things.”


Dr. Tommy Wood is a neuroscientist, Associate Professor at the University of Washington School of Medicine, and author of The Stimulated Mind. With degrees from Cambridge and Oxford, he has published more than 100 scientific papers and lectured worldwide on brain health, metabolism, and human performance. He also serves as a performance consultant to world-class athletes, including Olympians and Formula 1 drivers, and co-founded the British Society for Lifestyle Medicine.
