#851: Dr. Tommy Wood — How to Future-Proof Your Brain from Dementia

Tim Ferriss hosts Dr. Tommy Wood, an associate professor of pediatrics and neuroscience, focusing on brain health across the lifespan. They delve into various aspects of cognitive health, emphasizing that cognitive decline isn’t inevitable and there are many lifestyle changes that can be enacted for improvement. Dr. Wood discusses his background in biochemistry, medical training, and his role in motorsport performance while highlighting how nutrition, exercise, and social engagement can collectively influence cognitive function.

The conversation also covers brain injuries in newborns, outlining therapies such as therapeutic hypothermia for hypoxic ischemic encephalopathy and caffeine use for apnea in premature infants. For adults, strategies for concussion recovery are discussed, including nutritional management and preventing hyperthermia.
Dr. Wood highlights the significant role of DHA and omega-3s in brain health, advocating for their inclusion in diets, especially for cognitive enhancement and recovery from injuries. They also touch upon the importance of physical activity, particularly open-skill sports like dancing or martial arts, which enhance cognitive performance by promoting neuroplasticity.

Another focal point is the impact of sensory loss, particularly in vision and hearing, on cognitive decline and the reversibility of these risks with interventions like hearing aids. The podcast emphasizes the importance of sleep quality, suggesting that small improvements in sleep can lead to broader benefits for cognitive health. Dr. Wood advocates for actionable steps toward better brain health, culminating in a well-rounded discussion about his upcoming book, "The Stimulated Mind," which provides insights into maintaining cognitive vitality as we age.
