This episode is brought to you by One Skin, Bon Charge, and Manukora Honey. As we age, many of us worry about losing the ability to move freely or manage daily tasks—and with Alzheimer’s on the rise, cognitive decline is a growing concern too. But here’s the good news: just as we can preserve mobility well into our later years, we can also maintain a sharp, healthy mind. Today on The Dhru Purohit Show, we’re bringing you a special compilation episode featuring Dhru’s conversations with leading experts on how to live a vibrant life into your 100s. Dr. Dale Bredesen explains why cognitive decline is no longer a mystery—and why it’s not an inevitable part of aging. He emphasizes the importance of early prevention and shares seven foundational strategies to help protect your brain decades before symptoms appear. Juliet and Kelly Starrett join Dhru to share their practical, no-frills approach to promoting durability and mobility as we age. They cover simple at-home mobility tests like the sit-and-rise test. Their insights show how small, consistent changes in diet and movement can lay the foundation for lasting vitality and a body that recovers well from setbacks as you grow older. Dr. Dale Bredesen is internationally recognized as an expert in Alzheimer’s disease and is the author of several New York Times bestsellers.. He serves as the principal investigator for the Alzheimer’s Disease Research Center at UCLA and founded the Alzheimer’s Drug Development Network in 2008, which helped identify new therapeutics for the disease. Juliet Starrett is an entrepreneur, attorney, author, podcaster, and professional whitewater paddler, winning three world championships and five national titles. Dr. Kelly Starrett consults with elite athletes and coaches. Juliet and Kelly Starrett founded The Ready State fitness podcast and blog, San Francisco CrossFit, and are co-authors of the Wall Street Journal bestseller Deskbound and the New York Times bestseller Built to Move.

Chapter 1: What are the key strategies to prevent cognitive decline?
We talk about how prevention starts decades before symptoms show up. And Dr. Dale Bredesen shares why getting a cognoscopy starting around age 40 might be the smartest move you can make for your brain. Then I also talk with Juliet and Kelly Starrett, co-authors of the Wall Street Journal bestseller, Deathbound,
and the New York Times bestseller Built to Move about how longevity starts at ground level. Literally, they explain why your ability to move freely and get up off the floor with ease is one of the best predictors of how well you age. It's crazy, but it's true. But first, let's dive in to my conversation with Dr. Dale Bredesen.
Everybody pretty much knows somebody that has had dementia, Alzheimer's. And they're thinking they might be in their 30s, 40s, 50s, 60s, 70s. And they're not having a sense that they know of right now that they are diagnosed with something or that they have a level of cognitive decline that is sort of seriously impairing their day. They may still have it.
They just don't know that it's kind of going on. And at least they haven't been told. And they're looking for what are the things that I can do? to at least based on your experience, especially if I don't have access to one of these clinicians, what are the things that I could be doing today that could be potentially reducing my risk of developing Alzheimer's?
Chapter 2: How can exposure to biotoxins affect brain health?
Yeah, it's a really important point. So if you're 40 or over, we recommend that everyone get a cognoscopy. So we all know when we turn 50, what are we supposed to do? We're supposed to get a colonoscopy, and it can really reduce your risk of dying of colorectal cancer. Of course, pap smears did a tremendous job for reducing cervical cancer.
And by the same token, getting a cognoscopy if you're 40 or over, and especially if there's been any sort of family history, but in general, for all of us, because we are all at risk. It dwarfs the pandemic. We're talking about 1 million who've died in the US from the pandemic. About 45 million of the currently living Americans will die from Alzheimer's if we don't do something about it.
So again, nobody should get this. There's a tremendous amount you can do. Get a cognoscopy, which is some blood tests and a simple online cognitive test, as you mentioned earlier. and then MRI with volume metrics and some simple things you can do. We talk about the seven basics.
And before we go to the seven basics, just since we have you here, I want to tease these out a little bit more and really make sure we understand. So for the blood test and the cognition test and some imaging, are people convincing their current practitioner that they want to get this done? And do you have a link or a resource?
Or do they have to find a specialized physician, functional medicine, somebody that leans heavily towards lifestyle medicine to run these tests for them?

Chapter 3: What is the connection between mold toxicity and Alzheimer's?
It's a great point. And we see yes and no. So I would say what I'm seeing is about a quarter of the people, their doctor will say, sure, I'll do these for you. No problem.
Especially when it comes to the blood work. What's some examples of some of the blood work that they're running?
Yeah, so they're running things, again, which makes sense when you look at what is important for innate immune activation and for energetics. So they're running HSCRP, and they're running homocysteine. And TGF-beta-1 is actually a very good thing to know about yourself, that or MMP9. Again, these are things that are responding typically to biotoxins and other inflammogens.
And then you're looking at your HOMA-IR. So you're looking at your fasting glucose, you're looking at your fasting insulin, you're looking at your hemoglobin A1C, you're looking at your methylation. You know, we're now, there are some new things so that you can now look at your epigenetics. And you mentioned earlier the advanced lipid profile.
So you're looking at, you know, how are your lipids looking and do you have an inflammatory pattern or not? And then you're looking at, do you have toxin exposure? And we see this a lot where people will have biotoxin exposure, often in association with low platelet counts and or low white blood counts.
And this is something that Dr. Joe Pizzorno has pointed out many times in the past, that many of us are exposed to toxins. And one of the things that we see and that we don't often pick up as physicians, is that people will have often low white counts and or low platelet counts. And it's telling you there's something that is interfering with these.
And what would fall into the category of biotoxins, right? What are some of the things that people have probably heard about on this podcast? Like what exposure would they have had? What kind of toxins are we talking about? All right, it's May, and that means celebrating mothers.
Whether you're a mom, have a mom, or simply admire the strength that it takes to do it all, this month is a reminder that moms, the ultimate caregivers, deserve care too. That includes our skin. That's why I'm excited to put the spotlight on OneSkin, a brand that I love and that I've gifted to the moms in my life.
Their products are true multitaskers designed to hydrate, protect, and support your skin's long-term health. The secret? OS01, a breakthrough peptide that targets zombie cells, the dysfunctional cells that accelerate the signs of aging like wrinkles, dryness, and thinning skin. My mom and sisters love the OS01 face and their mineral sunscreen.

Great point. So if you go back, the toxins that cause cognitive decline break down into three groups. There's the inorganics, and that's air pollution, and mercury, and things like that, heavy metals. Because actually, not only does amyloid, not only is it part of your innate immune system, it is a metal-binding protein, actually quite tightly. So it binds zinc and copper extremely well.
Secondly, organic toxins. So things like formaldehyde and glyphosate and toluene and things like that. But then thirdly, as you mentioned, biotoxins. And these are typically things made by molds, although there are other organisms that make biotoxins as well, but they're typically trichothecines. Those are the ones that I worry about the most because these are made typically by Stachybotrys.
Um, so it's, you know, the, the, the, the five big mold species that you worry about with these are stachybotrys, penicillium, aspergillia, aspergillus, um, ketomium, and walemia. Those are the five typical bad guys. Uh, and so, and they're making things like trichothecines and ocratoxin A and gliotoxin, uh, and things like that, that actually turn out to impact your immune system.
And you know, you're, The mold wants your immune system to be turned down so that it can live, so that it can stay there. And so it is trying to turn that down, unfortunately. And of course, your immune system is saying, no, I want to recognize this and I want to get rid of it. So these are ones that I am most concerned about.

Chapter 6: What are effective tips for improving sleep quality?
Yeah. The mold thing, you know, I'm not a physician, I'm not a researcher, I'm not trained in any kind of classical way on any of these things, but from being in this world and kind of being somebody who knows people, I get a lot of friends that are asking me about
mold because either they feel you know i think the estimates by the world health organization or that 40 of buildings have some sort of you know toxic mold exposure that's there right that's just like the standard estimates that are there and there's more and more people that have been talking about it there's new tests that are available people can test their urine and they see that this is an issue and they might feel they have one of the symptoms
which is tough because mold can pretty much cause any kind of symptom that's out there. And I find that mold is tricky in a sense that it's hard to identify in the home. There's like a whole debates on this topic. I'm sure you know all about it. Because most mold that people are looking for, you're not looking for moldy food. Obviously, nobody should be consuming moldy food.
You're looking for mold contamination from leaky faucets, pipes, drywall, construction, and often it's not visible. It's not like you go into a room and you kind of, you know, pull a little bit of paint off the wall and you have a bunch of black mold. Sometimes it's that. Most often it's a lot more complicated. It's rotting wood. It's tough to find.
And usually it's people who have had symptoms for a while and maybe hear a podcast like this and are like, maybe I should talk to a naturopathic doctor or a functional medicine doctor. And that's somebody who helps them kind of dig into it a little bit. So finding the mold in the house is tough in the first place. And then on top of that, especially if you're a homeowner,
treating and deciding how to treat and remediate the mold is very tough too, because it could sometimes be so baked into the building that people are literally deciding, do they move, do they stay, right? Because it's that difficult to remediate.
All this to say that I've found that it's very tricky to go down the mold rabbit hole, but that doesn't mean that people should not understand that it's a central part of cognitive decline for a lot of people.
That being said, for this category of people who are listening, who maybe aren't diagnosed with something yet, I think that it's important that, and please feel free to push back on this, by the way. I'm putting out a theory.

Chapter 7: What role does daily fish oil play in brain health?
I think it's important to remind people that in addition to good ventilation and air filtration in the home, which only does so much, making sure that people actively are working out.
that they are doing strength training, that they're avoiding ultra-processed foods, that they're working on becoming not insulin resistant anymore and cutting them out of large pharmaceutical dosages of carbohydrates because those things, even if there is mold exposure, they can't reverse it but they can at least minimize the impact to the body.
Chapter 8: Why is the sit-and-rise test an important indicator of longevity?
And that's a lot more in people's control than the topic sometimes I find as somebody who's in the space of mold can be so complicated to dig down.
It's such an interesting point. And, you know, it reminds me of these old movies you see, you know, where there are 10 people and it's a rainy night and they're in a hotel together. And then suddenly there are only nine. One of them gets killed and then there's eight. And, you know, they keep looking at each other to say, who is the murderer here?
You know, you're looking at this, now there's seven. Murder mysteries, just like there's one with John Cusack years ago. And so the mold's a little bit like that. It's like, we're looking around like, what is causing this decline? Like, could it possibly be this mold that like is everywhere? And, you know, it kills me to say that it does seem to be a common contributor.
I asked the physicians who were doing the trial, what percentage of your patients do you think mycotoxins are a contributor? The answer was 80%. I couldn't believe it. So now that's not to say it's the only contributor. It's one of many.
Would they, would you, if you would ask them again, would you say that if you had to kind of really sort of stress test that idea, would they listed of all the insults that you know of all the potential contributors, causes, et cetera, contributors, I don't want to say causes, would they put mold in the top three?
Would they put it in the top five? Yeah, I think for sure it would be in the top five. I think in many it would be in the top three. What we find, we published this years ago, that probably 15 to 20%, it's the main thing. It's the main thing. It's the thing that you're really out of focus.
But Dr. Christine Burke over here near Sacramento, I thought made a really interesting observation and others have seen this, but I think she brought up a really good point. which is when she sees her patients and she does exactly the things you're talking about, she gets them to be metabolically flexible, she gets them to do the basics. We started talking about the basic seven.
So when she does the basic things, she buys them nine to 12 months, they do well. And then after that, if she doesn't find the specifics that are causing this, if she doesn't find, oh, there's pathogens that I need to deal with, or there's mycotoxins, if they don't deal with those specifics, they won't sustain that improvement. But I thought it was a very important observation
And we've seen it before. And Julie Gee, who works with us and who herself is APOE4 for, she's the one who founded the website, APOE4.info, and has done such a wonderful job and has taken herself from 35th percentile to 98th percentile. She's sharp as a tack. And she's now over 10 years on this overall approach. She had about four years. So she was doing things, you know, really, really well.
