How big of a role does diet play in perhaps prevention and even slowing decline?

A lot of these cohort studies have found the link between different food groups,

different nutrients, and also with different dietary patterns like mind diet,

Mediterranean diet, the dash diet, how they correlate with cognitive and mortality decline.

So I would say we do have currently good observational studies

indicating that there is an association between what we eat and our cognitive and

motor behavior in older age.

Welcome to the exam room podcast brought to you by the Physicians Committee.

Hi, I am the Weight Loss Champion Chuck Carroll.

Thank you so very much for raising your health IQ with us.

This is episode 57 from season 4, number 252 overall.

And today we are going to be talking about not just Alzheimer's disease,

but for what I believe is the first time here on the exam room,

we're also going to be talking about Parkinson's disease.

And so today I'm going to be joined by a woman who is devoting her career to teaching

and researching both of them.

And she is a nutritional epidemiologist at Rush Alzheimer's Disease Center as well

as an assistant professor in internal medicine at the Department of Clinical Nutrition at Rush.

Dr. Pooja Agarwal, she is here today and she will be looking at the cognitive

and motor decline that those living with Alzheimer's and Parkinson's will experience.

How much of a role does nutrition play though in preventing that decline?

In slowing that decline.
