Episode notes

The bulk of today's AMA is going to be around what are the measures that we can take? What are the modifiable behaviors that factor into risk reduction or prevention? Here's the problem. Really difficult to do this directly with control trials given the time course. You're going to see a couple of examples where we can, I think, pretty convincingly take a causal view.

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.
