About this listen

We all know the heart pumps blood — but we rarely think about what that means for the brain.

In this revealing conversation, cardiologist Dr. Josh Yamamoto explains how the way our blood vessels age can directly influence memory, focus, and long-term brain health. He breaks down what happens when arteries stiffen, inflammation builds, or heart rhythm subtly shifts — and how those changes can quietly reduce blood flow to the brain years before symptoms ever show up.

Dr. Yamamoto also dives into fascinating differences in vascular aging between men and women, why traditional blood pressure readings don’t always tell the whole story, and why personalized care matters more than one-size-fits-all guidelines. From exercise and medication to smart monitoring and prevention, he offers clear, practical steps to keep circulation strong and protect cognitive health as we age.

If you’ve ever wondered whether dementia risk is something you can take control of, this episode delivers both clarity and real-world hope.
