Muscle Doctor: The Shocking Link Between Muscle and Dementia

Most people think brain health starts in the brain.

But what if one of the biggest drivers of focus, memory, and long-term cognitive health is actually your muscle?

In this episode of the Kwik Brain podcast, I sit down with Dr. Gabrielle Lyon, a leading physician and New York Times bestselling author of Forever Strong, to break down why building muscle is one of the most powerful ways to protect your brain and age well.

We explore how skeletal muscle acts as a metabolic and neurological organ, influencing cognition, impulse control, emotional regulation, and even dementia risk.

In this episode, you’ll learn:

☑️ Why muscle health directly impacts brain function and neuroplasticity

☑️ How insulin resistance in muscle shows up before cognitive decline

☑️ Why Alzheimer’s is often called “type 3 diabetes of the brain”

☑️ How resistance training improves focus, memory, and executive function

☑️ Why leg strength is one of the strongest predictors of brain health

☑️ How to build muscle and cognitive resilience at any age

☑️ Why taking action before you feel ready is essential for long-term brain health

If you want to think clearer, stay mentally sharp as you age, and protect your brain long term, this episode shows you how physical strength becomes a mental advantage and why your future brain depends on what you do today.
