Can Dementia Be Reversed? What Your Brain Needs to Stay Sharp

The changes that lead to cognitive decline begin decades before symptoms ever appear. In this eye-opening episode, Dr. Saunders breaks down what is actually happening inside the brain when dementia develops, why Alzheimer's is closely tied to blood sugar and insulin resistance, and what you can start doing today to protect your memory and keep your mind sharp — no matter your age.

*Plus, Dr. Saunders answers viewer questions on a variety of health topics including short-term memory loss, tremors, pre-diabetes, blood pressure, and more.*

In this episode, Dr. Saunders covers:

• Why dementia is NOT an inevitable part of aging — and what actually causes it
• The blood sugar and brain connection — why Alzheimer's is called "type 3 diabetes"
• How your brain cleans itself out every night during deep sleep
• Why stress may be responsible for up to 80% of cognitive decline
• The role of omega-3 fats, ketones, and glucose transport proteins in brain health
• What kind of fasting actually gets ketones into your brain
• Mental exercises that physically grow your brain — and what happens when you stop
• Early signs of cognitive decline and when it can still be fully reversed
