In this monologue Dr. David Perlmutter critiques the dominant amyloid hypothesis for Alzheimer’s disease, revealing that a foundational 2006 Nature study—cited over 2,300 times—was found by a six‑month Science investigation to contain fabricated images, rendering the research fraudulent. He emphasizes the massive financial consequences: billions of dollars from the NIH and pharmaceutical companies have been funneled into amyloid‑targeted drug development based on this flawed work, diverting resources from alternative approaches. Perlmutter cites researchers such as Rudolph Tanzi, who suggest amyloid may be protective, and Dale Bredesen, who advocates a multifactorial view of Alzheimer’s that includes diet, lifestyle, toxins, and infections. He then juxtaposes this with a recent Neurology study of 72,063 UK Biobank participants, which found a strong association between high consumption of ultra‑processed foods (e.g., soft drinks, processed meats, packaged breads) and increased dementia risk over ten years (risk rose from 9% to 28% across low to high intake). He interprets this as evidence that lifestyle modification—eating minimally processed foods, getting restorative sleep, exercising daily, maintaining social connections, and spending time in nature—offers a viable preventive strategy. The talk concludes with a personal note about his father’s Alzheimer’s and a call to base medical decisions on sound science.

When we don't have a cure for Alzheimer's or even a meaningful treatment. Most of the meaningful treatments we are told about, which really aren't meaningful at all, are based upon what we now know is fraudulent research. Well, hello everyone. I'm Dr. David Perlmutter. One of the most fundamental tenets of research and what we do in clinical medicine is to review good science, to support our behaviors by good scientific research. You know, Alzheimer's disease has been a personal interest of mine for decades, that's for sure, both professionally and as it relates to my personal life. We know that 6 million Americans are now diagnosed with Alzheimer's disease. There are tens of millions of individuals globally who suffer from this disease. And for me, one of my motivations has been, of course, the fact that my own father passed from Alzheimer's as well. We've got to base our decisions in the treatment of Alzheimer's and any other medical problem for that matter on good science. This is really called to question as of late because of a Science publication that represents a 6-month investigation into one of our most foundational research studies ever done on Alzheimer's disease, a study that has been cited more than 2,300 times by other research Because it relates to what has been called perhaps the cause of Alzheimer's disease. Now, mainstream medical science would like us to believe that the cause of Alzheimer's disease is the accumulation in the human brain of a type of protein called beta amyloid. And this foundational research that served to propel us moving forward With further research to look at this accumulation of beta amyloid, again as a cause of amyloid accumulation, meaning Alzheimer's disease in the brain, was done back in 2006 and published in the journal Nature. This was a study that looked at the accumulation of a specific type of amyloid in the brains of laboratory animals and showed that when there were high levels. Of this specific type of amyloid in the brains of these rodents, they got Alzheimer's disease. We now know, according to this recent publication in Science, representing again a 6-month investigation of this original research, that the research was fraudulent, meaning that the images that they published showing this accumulation of beta amyloid were reviewed by what is called a forensic image consultant and found that these images were fake. They were doctored and they were fake. This is profound because what it's telling us is that one of the most foundational research studies that, as I mentioned, was cited thereafter by more than 2,300 other research papers papers and was the starting point for the same researchers to do 70 more research studies based upon this original research was flawed. Now, why is that important? It's important because billions of dollars have been dedicated by researchers under— supported rather by pharmaceutical companies to create treatments based upon ridding the brain of this toxic, so-called toxic protein, beta amyloid, as a potential treatment or even cure for senile dementia of the Alzheimer's type, or even helping humans not accumulate this beta amyloid in their brains. We know that here in America, the National Institutes of Health just this year has— this fiscal year has dedicated $1.6 billion to research that is founded on this notion of accumulation of amyloid in the brain. And again, this Science publication has revealed that this research, the original research, one of the foundational studies, was fraudulent. So think of the billions of billions of dollars that have been dedicated to this amyloid hypothesis based upon this fraudulent research. And that is billions of dollars that could have been dedicated to researching other ideas for these tens of millions of Alzheimer's patients in the world today. It's tragic. It's heart-wrenching, but the upside is that it's been revealed. We now know that, you know, this amyloid hypothesis may not be all that it has been cracked up to be. This idea that ridding the brain of this toxic protein may not be what we should be doing. Wonderful work by researchers like Dr. Rudolph Tanzi at Harvard have revealed that this amyloid accumulation in the brain might actually be there to to protect the brain. So we really think about the work of people like Dr. Dale Bredesen, who make us— challenge us to explore the notion that Alzheimer's is not a disease caused by one variable, that multiple variables like diet and lifestyle and toxins and perhaps even infectious organisms may conspire to bring about what we call the degradation of the brain and cognitive function that goes by the name of Alzheimer's disease. Now, I want to just juxtapose this study with another study that also has come out recently, and it was published in the journal Neurology. Neurology is perhaps one of the most respected peer-reviewed journals dealing with clinical manifestations of brain disorders and peripheral nerve disorders. It's put out by the American Academy of Neurology That's the group that sanctions us as being what are called board-certified neurologists when we are board-certified by this organization, the American Academy. So, and what I'm saying is highly respected journal, and they published a study actually this week that looked at the risk of Alzheimer's in individuals who consumed what are called ultra-processed foods. And what does that mean? It means foods that have been excessively processed, like soft drinks, ketchup, mayonnaise. I'm going to list a few of them: packaged breads, flavored cereals, deep fried excuse me deep fried chicken, sausage, ice cream. Foods that have been processed, foods that have really been designed to give us a real push as it relates to a refined carbohydrate, raising our blood sugar, challenging us to be. More insulin resistant, and of course, we know the relationship of insulin resistance and even type 2 diabetes to risk for Alzheimer's disease. They followed a group of 72,063 individuals 55 years of age or older who did not have dementia in England using data from what is called the UK Biobank cohort. They followed these individuals for 10 years, and what they found was In this group of individuals, 518 of them developed dementia. The risk for developing dementia in those who ate the least ultra-processed foods was 9%. That would be those individuals eating about 225 grams of ultra-processed foods a day. The risk for developing dementia in those who consumed the highest amounts Like 814 grams per day as an average, their risk was 28% as compared, compared to the group eating the lowest amounts of processed foods, 9%. This is an association. It doesn't prove causality. But what the researchers demonstrated was that in the group that ate the most highly processed foods, Their risk was dramatically increased. For every 10% increase in the consumption of highly processed foods, there was a 25% increased risk of dementia. You know, I'm glad this study was published. To be fair, to call it like it is, we've been talking about the dangers of ultra-processed foods in terms of brain health for at least 15 to 20 years. You all know that's true. The reason we've been talking about it is because of how ultra-processed foods affect blood glucose, affect insulin sensitivity, and as we now know, how ultra-processed foods affect uric acid levels, something we've been quite interested in as of late. So I juxtapose these 2 reports. First, that this amyloid hypothesis in terms of being the cause of Alzheimer's disease is based upon fundamentally research that we now know is fraudulent, A, and B, the idea that a lifestyle change like deciding to consume fresher foods, foods that have not been ultra-processed, you know, the whole idea of The term ultra-processed foods is, for me, an oxymoron because at that point when they've been ultra-processed, are they really even foods to begin with? But anyway, the notion that prevention of Alzheimer's disease by making lifestyle changes is certainly something that has great validity as demonstrated by wonderful science. When we don't have a cure for Alzheimer's or even a meaningful treatment, Most of the meaningful treatments we are told about, which really aren't meaningful at all, are based upon what we now know is fraudulent research. So do your best to eat well, get enough sleep, make sure your sleep is restorative, exercise if you can every single, every single day, form good and lasting relationships, get out in nature. Connect to other people and be grateful for all the good things that surround you. Thanks for listening and thanks for joining me today. I'm Dr. David Perlmutter. Bye for now.
