Improve Your Brain to Avoid Alzheimer's, Dementia & Memory Loss with Dr. Perlmutter

Dr. Perlmutter is on the forefront of research about ways to protect and support the brain in a world where Alzheimer’s, dementia, and other brain-related diseases are on the rise.

Alzheimer’s disease affects a staggering number of Americans today—5.5 million. In fact, if you live to be age 85, your chance of getting Alzheimer’s is 50/50.

Even more shocking, the Alzheimer’s Association estimates that number could increase to 16 million by 2050.

It’s not all bad news, though, as my guest today is here to assure us.

Dr. David Perlmutter on Preventing Alzheimer’s

Dr. Perlmutter is a Board-Certified Neurologist, Fellow of the American College of Nutrition, and four-time New York Times bestselling author. You’ve probably heard of his popular book Grain Brain: The Surprising Truth About Wheat, Carbs and Sugar–Your Brain’s Silent Killers. He has published extensively in peer-reviewed scientific journals and has been interviewed by everyone from Larry King, Oprah, Dr. Oz and many others.

While Dr. Perlmutter is all for finding a cure for Alzheimer’s (currently there isn’t one), as a functional medicine doctor he’s also all about acting on the medical research that shows this disease is largely preventable with the right lifestyle choices.

Dr. Perlmutter sums it up well (by quoting former President John Kennedy):

The time to fix the roof is when the sun is shining.

I couldn’t agree more. Take a listen!
