Your Brain's Destiny Is Not Fixed with Dr. David Perlmutter

What if the future of your brain isn't predetermined by your age, your genetics, or even your current health?

In this fascinating and empowering conversation, Marci sits down with renowned neurologist and six-time New York Times bestselling author Dr. David Perlmutter to explore groundbreaking research that could completely change the way you think about brain health and aging.

At the center of Dr. Perlmutter's newest book, Brain Defenders: Harness the Power of Your Brain Cells to Protect Your Brain for Life, are tiny but incredibly powerful cells called microglia which are the immune cells of your brain.

When functioning as they're designed to, microglia help protect your neurons, strengthen the connections between brain cells, repair the blood-brain barrier, and keep your brain resilient. But when these cells shift into a more inflammatory state, Dr. Perlmutter explains, they may contribute to cognitive decline and a range of neurological conditions.

Here's the hopeful part: you have far more influence over this process than you may think. Dr. Perlmutter shares how everyday choices—including movement, nutrition, restorative sleep, social connection, and even having more fun—can support your metabolic health and, in turn, help support the health of your brain.

In this episode, you'll discover:

● Why Dr. Perlmutter believes your brain's immune system may be one of the most important and often overlooked keys to lifelong brain health

● What microglial cells are and the surprising role they play in protecting, repairing, and maintaining your brain

● Why the metabolic choices you make today may influence how your brain functions decades from now

● The simple daily practice Dr. Perlmutter considers foundational for protecting your brain as you age

● Why both aerobic exercise and strength training matter to your brain's health and what your muscles have to do with growing and protecting brain connections

● The fascinating connection between social interaction, oxytocin, and your brain's immune cells
