Alzheimer’s and dementia aren’t just a matter of age or genetics. Increasing evidence shows that metabolic health—particularly insulin resistance—plays a key role in cognitive decline.
In this episode of A Whole New Level, neurologist and bestselling author Dr. David Perlmutter joins Mike Haney to explore the links between brain health and metabolism. They discuss the role of insulin resistance and inflammation in Alzheimer’s disease, the biomarkers that can reveal risk decades before symptoms, and how lifestyle interventions can dramatically change your trajectory.
Topics include:
- Key biomarkers for assessing brain health: fasting insulin, A1C, homocysteine
- Why targeting inflammation may matter more than targeting amyloid plaques
- The promise and limitations of GLP-1 medications for dementia and Parkinson’s
- Practical steps you can take now to protect long-term cognitive function
