In this “Ask Me Anything” (AMA) episode, Peter goes into depth on the topic of brain health, starting with how Alzheimer's disease is diagnosed, the significance of blood-based biomarkers in diagnosis, and what the various APOE gene variants mean in terms of a person's risk of developing Alzheimer's disease. Next, Peter discusses the various strategies for preventing Alzheimer's disease and neurodegeneration. He touches briefly on exercise as a potent tool, but focuses more on lesser-known factors that could impact brain health, such as nutrition supplementation, lipid management, brain games, sauna, oral health, hearing loss, and more.
