Summary

This episode explores how blood flow is the #1 brain imaging predictor of Alzheimer's disease and provides actionable strategies to improve cerebral circulation. The host discusses how blood vessel aging, rather than brain cell aging, drives cognitive decline, and recommends lifestyle changes, dietary interventions, supplements, and medical treatments to enhance brain blood flow.

Insights
  • Low blood flow to the brain is the leading imaging predictor of Alzheimer's disease, making vascular health a critical prevention target
  • Brain cells don't age; rather, blood vessel deterioration is the primary driver of cognitive decline and neurodegeneration
  • Walking speed at age 80 is a powerful longevity predictor—those maintaining 3 mph walking speed have 90% survival to age 90 versus 10% for those at 1 mph
  • Multiple modifiable risk factors can improve cerebral blood flow, from dietary choices to exercise intensity to emerging therapies like hyperbaric oxygen
  • Cardiovascular health directly impacts brain health; treating heart disease and hypertension is essential for cognitive preservation
Trends
Growing clinical focus on vascular aging as primary mechanism of Alzheimer's disease rather than amyloid-centric modelsIncreased research validation of hyperbaric oxygen therapy for brain injury recovery and cognitive enhancementLifestyle-based preventive medicine gaining prominence in neurodegenerative disease managementIntegration of functional medicine approaches (supplements, dietary interventions) into mainstream brain health protocolsEmphasis on measurable biomarkers like walking speed as predictive indicators of longevity and cognitive health

Every day you are making your brain better or you are making it worse. Stay with us to learn how you can change your brain for the better every day. B is for blood flow, which is critical to life. Blood carries nutrients to every cell in the body and removes toxins. Low blood flow is the number one brain imaging predictor of Alzheimer's. New research suggests that brain cells don't age, rather it's your blood vessels that age. Anything that damages them damages your hippocampus and starves Scarlett and Sam of the nutrients they need. So how do you improve blood flow today? Limit caffeine and nicotine, both constrict blood flow to the brain. A cup of coffee a day is not a problem, but more caffeine than that can be trouble. Be serious about treating high blood pressure. As blood pressure goes up, blood flow to your brain goes down. If you have any heart issues, be serious about treating them. Anything that damages your heart also damages your brain, and avoid being a couch potato. On the other hand eating chili peppers and beets can help increase blood flow as can taking the supplement Ginkgo The prettiest brains I ever seen take Ginkgo Exercise, especially walking like you're late. Did you know that people who are 80, who can walk three miles an hour, have a 90% chance of living to 90? But those who can only walk one mile an hour have a 90% chance they won't live to 90. Also, I like a treatment called hyperbaric oxygen therapy because I've seen it increase blood flow to the brain. We published a study on the use of hyperbaric oxygen on veterans with brain injuries and showed it significantly increased blood flow and helped improve their memory and mood. Throughout the program, I'll talk about how important the right foods are to your memory. My wife, Tana, and Amen Clinic chef, Honor Harvey, have created recipes to support each of the Bright Mind's risk factors. One of my favorites is Beet Street Tacos, which contain 10 different ingredients to support healthy blood flow. We would love for you to leave us a comment, question, review, subscribe.
