A few quotes:
> Despite the certainty inferred by the book’s subtitle, there is no published study that tests or proves the hypothesis that the Bredesen protocol can prevent and reverse cognitive decline.
> Readers are informed that participants with subjective cognitive impairment or mild cognitive impairment are included in the studies; however, both conditions can have causes unrelated to neurodegenerative processes. These studies are therefore not targeting a common underlying neuropathological process of Alzheimer’s disease, as the papers suggest.
> Readers might not be aware that the three case series evaluating the Bredesen protocol appear in journals considered by some to be predatory open access journals. [...] The journal Aging, where the first two articles were published, appears on the Beall’s list of potential, possible, or probable predatory open access journals [...]
> it is notable that the Bredesen protocol has been made commercially available; however, the authors do not disclose any conflicts of interest in their scientific reports.
One would also assume that simply exercising and eating properly on their own would have some measurable improvements. As the paper suggests, a larger case study would be in order, specifically with some combinations of the various measures in the protocol to determine individual and compound efficacy on a statistically relevant scale.
Why? Which one has better policies?
PMC also makes everything uniformly formatted which is often a benefit, though sometimes equations can be worse.
I find it amusing the Lancet complains about this considering Peter Daszak's et al covid origins letter was published without disclosing conflicts of interest.
Anyway, here’s a Rhonda Patrick interview with Bredeson for the curious. So few people will actually do the protocol, time will tell if there’s anything to it.
Not seeing Bredesen on the bibliography so I think the research is independent, some related citations from that bibliography:

So the claim is that ultraprocessed food is essentially making your mitochondria sick, and the recommended diet adjustment is not very different from Bredesen’s approach.
These are harmless until they become harmful. What if we develop a good cure for Alzheimer's in 10 years, this method gets debunked but the method makes many refuse to use the conventional treatment? That isn't a made up scenario, it happens all the time. Announcing that something is a cure without evidence is hurting people.
Anecdotally, I experienced a rather severe cognitive impairment after statin use, which, when discontinuing the statin was reversed. I believe this could be attributed to mitochondrial damage. Were I an older individual, this might be improperly diagnosed as age-related cognitive decline.
In another example, 60 Minutes ran a story on a group of people who were suffering from late-stage AD. After autopsy, some showed amyloid beta plaques in some cases and the total absence of it in others. This leads me to believe that AD, as it is currently understood, is better classified as a syndrome which may have no single definitive cure.
Scientific progress has often been speculative and messy. The few thousand people with ApoE4 genes who read his book and then actually commit to time-restricted feeding, exercising 4 times a week, sleeping 8 hours, and semi-ketogenic diets might have better outcomes a decade from now than those who don't. If that discourages another few tens of thousands of people from taking a potential blockbuster drug in the early years after its release, fine. It's worth the natural experiment to find out because millions of people are not getting much relief from current treatments [2]. This is even more true given that Alzheimer's isn't communicable.

In fact, the only other country with a population of more than 200,000 people with a higher obesity rate than the US is Kuwait.
Learning how unhealthy the culture I grew up in is has been a gradual process. Shock moving to the west coast, and then shock at each of the subsequent moves around other parts of the world.
Maybe 29% is staggeringly unhealthy, but it isn't American culture to be that overweight. Being overweight is fairly widespread and not unique to America.
Probably it has more to do with lifestyle changes (e.g. cars and working at computers) and diet changes (rise of processed and fast food). These things have disparate impact on racial groups, e.g. hispanics and blacks are considerably more overweight than whites. America having more hispanics and blacks than places like the UK, the US seems like it is more obese.

Happy with those numbers? I'm not.
> hispanics and blacks are considerably more overweight than whites
Are these people not American?
To take that claim and infer that I mean to suggest the parts are not part of the whole is clearly nonsense.
I suppose the reason why some bristle at your partitioning of American obesity rates into racial groups is that it's unclear that it's particularly relevant. Obesity varies by income, urban/suburban/rural-ness, red state/blue state, and more.
Any of these dimensions could be used to partition America into tranches. Then, throw out the bottom tranches. Then, say that America isn't especially unhealthy.
Imagine person A says: There's an epidemic of gun violence in America.
Person B responds: No. Just ignore the urban gang violence, the mentally ill mass shooters, and the suicides. It turns out that among mentally stable Whites, America isn't that violent.
The reason to use racial groups in my example, is first because I happened to know obesity differed between the groups, and second because it offers the opportunity to look at similar groups in different countries. This example shows that there is variance within the country and similarity beyond it, which I think makes a good case that the culture of the country is not what's responsible.
Regarding your point on violence, suppose it were the case that left handed people had a murder rate 100x higher than right handed people. Now, imagine too that the OECD countries, or whichever group you would like to compare America too, were 99% right handed and America were only 90% right handed.
Would it make sense in this case to say that American culture was the root of the problem with American violence if right and left handed Americans committed violence at the same right as their OECD counterparts? I wouldn't think so. I would think the explanation would be as simple as "greater proportion of more violent left handers".
I realize in the violence example that I've simplified and exaggerated the case compared to obesity. I am not claiming that obesity rates are similar to my example.
You've listed the obesity rate, not the rate of people who are overweight. Beyond that, you haven't limited to adults. According to the CDC [1]:
Percent of adults aged 20 and over with obesity: 42.5% (2017-2018)
Percent of adults aged 20 and over with overweight, including obesity: 73.6% (2017-2018)
It absolutely has to do with lifestyle. America is one of the cultures most reliant on cars in the developed world. Physical activity is also ridiculously low. The problem is there's no way to reliably measure physical activity across countries. There's just survey data, and people in the US know they _should_ exercise.
I never claimed that we weren't unhealthy but that being unhealthy isn't "American culture" as evidenced by different demographics in America having markedly different obesity rates. The obesity rates are similar among similar demographic groups in different countries - e.g. white people in the US have similar obesity rates as UK, Canada, and Australia. It's very weird to say that this thing that is constant among demographic groups across countries is dependent on the culture of one country. Especially when it is different among demographic groups in the same country.
I am not implying that white people are genetically predisposed to obesity. Actually, what I wrote is the exact opposite. I suggested the obesity rates were due to environmental factors and, crucially, I pointed out that other racial groups have greater obesity rates. So, I explicitly stated I believed the difference was not genetic and that white people have less obesity in the US than non-white.
For the other points you seem to prefer using a different metric, overweight instead of obesity. You haven't said why that factor is more relevant or how it changes what I wrote above.
However, being physically active makes you more aware and mindful of the input side of the equation; building muscle mass, cardiovascular fitness and endurance in turn improves your metabolic ability to burn calories. So it's absolutely part of the picture. "The Miracle Pill" by Peter Walker is an excellent introduction to the topic.
Whether or not you actually meant it, this very clearly comes off as you saying that they aren't American.
"Seems", as in "appears to be, but is not actually." The only way the US is not actually more obese is if Hispanics and Blacks do not count as "the US".
The only other way to read "seems" here is in the "I'm not totally sure, but this is what it looks like" sense. But this doesn't seem to be the way you're using this word, especially given that your entire comment is denying that the US is more obese purely in virtue of white obesity statistics.
It's pretty clear that "seems" means that obesity seems to be a US problem unless you start looking at demographics, where similar demographics in different countries have the same rate of obesity (e.g. white people in the US, Australia, and Canada) and demographics in the same country have different rates of obesity (e.g. in the US blacks, whites, and Hispanics all have different rates of obesity).
I was not denying that the US is obese, to the extent that it is. I was explaining that it is not "American culture" that is the issue. Multiple groups that share "American culture" have different rates of obesity and groups that don't share American culture do share obesity rates.
Another step to consider in lateral thinking about (personal diet -> diet book) is the marketing of such. Instead of allowing it on the marketplace, it could be sold by word of mouth in the manner of multilevel marketing. Many MLM systems act as giant siphons for unethical people. I wonder if a forking blockchain could act as method to promote honest transparency, where each level of organization becomes a fork.

It didn't help. If anything in my observations it made things worse. Though it's a meaningless sample size.
My mother going this way now too.
Suspect it will be me one day.
Certainly genetic factors involved.
Melatonin helps with sleep disorders... for people with sleep disorders. There is a synthetic analog called Ramelteon.
Intermitent fasting has curious effects on insulin resistance, but not clinically relevant.
Probiotics reduce incidence and severity of traveler's diarrhea... for travelers. It has been comercially available for a while.
Like Ivermectin, which is not snake oil, but is also being sold for the same purposes as snake oil.
I'm not a faster, don't have a dog in this fight, just curious as have seen a few papers & articles in recent years that seem to suggest a relationship between T2D / metabolic syndrome and dementia, but these may have since been debunked?
As the protocol is not accessible / published, we cannot determine how the difference in the set of measures between participants were determined and as such no researcher can independently replicate this study.
This is why those licensed diet / lifestyle change are never science: by definition. Even if they actually produce the desired outcome, all the research is produced either by the creator or by researchers that entered a license agreement and thus have conflicting interests and bias.
Sorry, such claim is a pure bullshit. It is reproducible, even the parts of the suggested treatment lead to significant improvements in quality of life for affected patients.
What we have here is: 1) the paper has some claims 2) it has weak theoretical coverage 3) it does not perform orthogonal hypothesis validation (validating each parameter in isolation) 4) the size of trial is small
Plus some political plays between scientific society participants.
But it is far from non-reproducible. There are a few people in the field who had big successes with similar therapies. (Dr. Derrick Lonsdale)

What ever happened to ballroom dancing and bridge?
I'm learning piano and it's a never ending brain game. You sit there for an hour trying to coax new neurons in various areas to grow.
Some exceptions apply: Sprinkle flax seeds on top for omega 3s, use iodized salt for iodine (seaweed is high in iodine but also high in bad heavy metals), get fresh air and sunshine for vitamin D, pick out your favorite source of vitamin b12. I believe you'll still need potassium.
For exercise: A good place to start is to walk and bike for transportation. Read this book if you're wanting to be convinced that exercise is a magic pill: Spark: The Revolutionary New Science of Exercise and the Brain

ketosis does something to the immune system. in many people who have schizophrenia, touching the immune system sometimes has a direct impact on symptoms. there is a famous case of a young man whos symptoms went away after having his bone marrow removed as reported in the NYT. the articles goes on to connect many interesting cases and facts that orbit this idea. its official everyone, the NYT knows more about medicine than your doctor. another article, published by a practicing harvard psychiatrist in psychology today, presents three case studies of schizophrenics who go into remission upon entering ketosis. other people find fleeting relief after donating blood and thus diluting their blood. and blood dilution has been shown to directly impact tons of things at UCB especially things having to do with aging. its an indication of whats to come. our own bodies are producing inflammatory molecules that cause disease.
i have schizophrenia and i can say that these things are true and i have tested them.
whether AZ disease improvement upon entering ketosis is due to inflammation reduction or metabolic improvements due to using BHB rather than glucose in some cells, im not sure anyone knows.
i wonder if any doctor will stop to reflect on his own behaviour for a single second after he hears that the titan of AZ medications, which reduces plaques, does not fucking work? people like me have been saying for ages that AZ is caused by metabolic dysfunction and the plaques are a downstream artifact. well now the evidence against them and for me is so massive that they will have to write it in the sky. pure vindication.
Not stupidity and stubbornness. There is exactly zero money to be made from fasting. Much better to try to make some miracle compound and sell it for $50 per pill and bill it from insurers.
>ketosis does something to the immune system
Keto utilizes a bit different metabolic pathway compared to the aerobic glycolysis [1, 2]. The reason you observe immune system response when you lower keto and increase hydrocarbons is because glucose metabolic pathway is broken in such patients. Their bodies cannot consume glucose in full and start to starve in ATP, up to the point of tissue damage, all that with excessive lactic acid excretion. When the tissues are damaged, immune system gets activated and attacks them. By doing so, it also affects nearby healthy tissues, leading to wavy but gradual disease progression.
This process is believed to play the crucial role in progression of neurological and cardiovascular disorders.
The part of glucose metabolism that gets often broken in a human is aerobic cellular respiration [2]. It may be an inherited genetical condition or an acquired mitochondrial dysfunction.
By the way, do you happen to have an insulin resistance? If this parameter is not ok, this can be an additional hint. But even if it is ok, the given pathological process may be in place and slowly progress, eventually leading to insulin resistance as well.
For example, the paper stresses that there is a dysfunctional signaling in AD and comes to a conclusion that it is inducted by a metabolic dysfunction. While this is a true statement, the amount of overall cellular damage happening under the conditions of insufficient metabolism goes way beyond that. The patients have not only "bad signalling", but also autoimmune-like response to damaged tissues. The paper fails to discuss that but suggests as a treatment target in "Therapeutic System 1.0".
The suggested treatment, however, contains the crucial elements that should bring the improvement to patients.
This is not a bad paper by all means. It is useful and even enlightening to some degree, but the theoretical part is tiny and not sound.
Regarding the critical article from The Lancet [1], it's full of emotions and nihilism. I.e. it is bad. I mean, really bad.
For example, here are some excerpts from critical article. "high out-of-pocket cost to implement" - bullshit. While the whole protocol may be costly depending on country, the mitochondrial (the most essential part of it) is dirt cheap, like tens-of-dollars per month cheap. Anti-inflammatory part of protocol can be implemented even with Aspirin.
"Readers might not be aware that the three case series evaluating the Bredesen protocol appear in journals considered by some to be predatory open access journals. Predatory open access journals are scientific-sounding publications that hijack the open access model for profit" - come on. The predatory closed-access model, on the other hand, has its own downsides, e.g. slow progress, walled gardens of authority, review rings.
"There are elements of the Bredesen protocol that could be beneficial and are largely free to patients. It is standard of care in dementia clinics to educate patients, without cost, on the lifestyle interventions" - and that's it. No mentions to metabolic corrections other that "lifestyle change". Which is not sufficient by itself. It only works in conjunction with mitochondrial + anti-inflammatory parts.
"When presented with this information, there are people who continue to hold a strong belief in the protocol’s efficacy." - because it is. Rather than loudly criticizing other's work, it is way better to join the ranks and improve the research by covering the missing parts.
"When carefully examined, multiple red flags appear in the scientific studies supporting the Bredesen protocol." - that's true.
"To date, the evidence does not support its claim to prevent and reverse cognitive decline" - oh well, don't get me started. To date, the neurologists try to treat such patients with... antidepressants. And that's it. Most of them do not even know about neuro-metabolical cause and effect connections.
