In this episode of the Lifespan podcast, Professor of Genetics, Dr. David Sinclair, and co-host Matthew LaPlante dissect the topic of brain aging.
They explore evidence suggesting that the brain ages more slowly than other parts of the body and highlight how cognitive function is impacted by aging. Different interventions aimed at preserving brain health are also discussed, including a plant-based diet, exercise, metformin, NAD boosters, and sufficient sleep.
