639: How to lower your Alzheimer’s risk at any age | Majid Fotuhi, M.D., Ph.D.

The podcast explores the preventability and reversibility of cognitive decline with Dr. Majid Fotuhi, a neurologist and author of "Invincible Brain." Dr. Fotuhi argues that up to 45% of dementia cases are preventable through lifestyle changes, emphasizing the importance of exercise, sleep, and addressing medical conditions like hearing and vision loss. He highlights that lifestyle factors, such as a Mediterranean diet and regular walking, can positively impact amyloid and tau levels in the brain, making the brain 18 years younger. The discussion also covers the five pillars of brain health—exercise, sleep, nutrition, mindset, and brain training—which can grow the hippocampus and improve cognitive functions.
