Dr. Tommy Wood: Enhancing Brain Performance & Preventing Dementia

In this episode, my guest is Dr. Thomas Wood, a UK-trained M.D. with a Ph.D. in physiology and neuroscience. He is a professor of pediatrics and neuroscience at the University of Washington. We discuss how both physical and mental challenges can enhance cognitive function in the short and long term. We also examine the crucial roles of nutrition, sleep, and other lifestyle factors in supporting overall brain health. Additionally, we explore the potential benefits of supplementation with creatine, caffeine, and certain vitamins and their impact on mental performance or recovery from traumatic brain injury (TBI). We explain the mechanisms by which different types of exercise—resistance, aerobic, and high-intensity training—positively affect brain health and longevity. We also discuss various behavioral approaches to combat brain fog and prevent age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s. This conversation explores many practical steps anyone can take to improve brain health, regardless of age or background. Read the full episode show notes at performpodcast.com.
