Up to 70% of dementia may be preventable. Yet most conversations still focus on what happens after decline begins. Cognitive resilience may be one of the most overlooked markers of long term health. Your brain’s ability to adapt, use energy efficiently, and maintain structure is shaped over time. In this episode, I sit down with Dr. Tommy Wood to discuss what actually drives cognitive decline, how white matter changes develop, and why metabolic factors like ketones can support a brain that struggles to use glucose effectively. Sometimes the question isn’t what happens when the brain declines. It’s what you’re doing today to protect it. Listen to the full conversation.
