Factors Linked to Optimal Aging Uncovered
https://neurosciencenews.com/optimal-ag ... 3yOWQD_Qwk
ApoE4s have more to be concerned with than just Alzheimer’s. While our gene seems to serve us well when young, it doesn't do us any favors when we age. But there are things we can do to help ourselves age well. What are the keys to “successful” or optimal aging? A new study followed more than 7000 middle aged and older Canadians for approximately three years to identify the factors linked to well-being as we age.

Omega-3 fatty acids
https://www.foundmyfitness.com/topics/o ... p7jhvj2dNk
We’ve emphasized the importance of Omega-3 intake before, now here’s more to add to the pile. ApoE4s tend to be longevity challenged and predisposed to cardiovascular disease, but Omega-3s can help with that:
• Having low omega-3 levels ranks among the top six causes of preventable death – right up there with smoking, high blood pressure, and obesity.
• Having high omega-3 levels may reduce a person's risk of cardiovascular disease by a whopping 25 percent.
• Taking omega-3s is associated with an additional five years of lifespan, on par with not smoking.

A hibiscus compound may help remove toxic plaque build-up in Alzheimer's
https://www.medicalnewstoday.com/articl ... PTy23DBrpM
• Accumulation of toxic aggregates of the beta-amyloid proteins in certain brain regions is often linked to the decline in cognitive function characteristic of Alzheimer’s disease.
• Studies suggest that impaired clearance or removal of beta-amyloid may contribute to the accumulation of beta-amyloid in Alzheimer’s disease.
• A recent study shows that gossypetin, a flavonoid present in the flower of a hibiscus species, facilitated the clearance of beta-amyloid in the brain of an Alzheimer’s mouse model.
• Treatment with gossypetin also attenuated deficits in memory and learning in the mouse model, highlighting the therapeutic potential of this compound in Alzheimer’s disease.

4 Surprising Things That Can Impact Dementia, From A Psychiatrist
https://www.mindbodygreen.com/articles/ ... DzJZFq13bI
With cognitive decline, it's important to focus on early intervention and doing what you can to prevent the onset—but that's not to say you can't do anything about it once symptoms arise. In the podcast contained in this article, functional medicine psychiatrist Kat Toups, M.D shares how she healed her own serious autoimmune disease and cognitive impairment. "Gradually, there came a day that my brain came back online," she recounts. "It was really exciting when I realized I could hold the seven digits of a phone number in my head and dial the number again.”

This reminds me of a recent episode of NOVA on PBS: The Truth About Fat. It can be viewed online. One takeaway … Sumo wrestlers don't have the chronic diseases that are associated with obesity despite their weight. The reason is their fat is subcutaneous, and their high level of exercise helps keeps the fat stores from becoming visceral.

MIND and Mediterranean Diets Associated With Fewer Alzheimer’s Plaques and Tangles
https://neurosciencenews.com/mind-medit ... cBd3_62KQA
People who eat diets rich in green leafy vegetables, as well as other vegetables, fruits, whole grains, olive oil, beans, nuts and fish, may have fewer amyloid plaques and tau tangles in their brain—signs of Alzheimer’s disease—than people who do not consume such diets, according to a study published in the March 8, 2023, online issue of Neurology.

Diet Not Genes Is Driving Dementia According To The British Medical Journal
https://www.prnewsblog.com/news/health- ... TeiCqkrjXE
A hugely significant study in the British Medical Journal into age-related cognitive decline and dementia has stated that changing your diet and lifestyle from bad to good cuts your future risk of developing dementia by a massive nine times
The study also shows, significantly, that whether or not you inherit the ApoE4 ‘Alzheimer’s gene’ that one in five people carry, it makes no difference to the positive reduction in risk achievable by simple diet and lifestyle changes.

Time-restricted eating reshapes gene expression throughout the body
https://www.sciencedaily.com/releases/2 ... 2O4ErDBFH4
“Numerous studies have shown health benefits of time-restricted eating including increase in life span in laboratory studies, making practices like intermittent fasting a hot topic in the wellness industry. However, exactly how it affects the body on the molecular level, and how those changes interact across multiple organ systems, has not been well understood. Now, Salk scientists show in mice how time-restricted eating influences gene expression across more than 22 regions of the body and brain. Gene expression is the process through which genes are activated and respond to their environment by creating proteins.”

Removal of Neuronal APOE4 Alleviates Alzheimer’s in Mice
https://www.lifespan.io/news/removal-of ... zRc1WLQuHk
The researchers created an ingenious mouse model of Alzheimer’s using mice that produced both human tau protein and either human ApoE3 or ApoE4. On top of that, the researchers developed a mechanism for switching off the APOE gene specifically in neurons.
As expected, the APOE4 mice exhibited much more severe AD symptoms than the APOE3 mice. If ApoE4 production in neurons was switched off, overall levels of this protein fell by about 30%, which matches the share of ApoE known to be produced in neurons. However, the reduction in tau pathology was much more substantial: 81%.

Mediterranean diet associated with a lower risk of mortality in older adults
https://www.sciencedaily.com/releases/2 ... yYEcbVuKto
A greater adherence to the Mediterranean diet which had been assessed through an index made with biomarkers during a 20-year scientific monitoring is associated with a lower mortality in adults over 65. This is one of the main conclusions of a study led by Cristina Andrés-Lacueva, head of the Research Group on Biomarkers and Nutritional & Food Metabolomics of the Faculty of Pharmacy and Food Sciences of the University of Barcelona (UB) and the CIBER on Fragility and Healthy Ageing (CIBERFES), also formed by the Food Innovation Network of Catalonia (XIA).

Is exercise more effective than medication for depression and anxiety?
https://www.medicalnewstoday.com/articl ... PTzAmqTfI8
Mental disorders are associated with accelerated aging and decreased lifespan. There’s a strong connection between mental, metabolic, and neurological disorders. But exercise can help.
• A large new analysis of meta-studies finds that exercise is more beneficial for conditions such as anxiety and depression than standard psychotherapy or medications.
• The new study found that essentially all forms of exercise produced significant mental health benefits.
• Shorter, high intensity exercise programs produced the greatest effect.
• Exercise provided the greatest mental health benefit to people with depression, or who had been diagnosed with HIV and kidney disease, pregnant and postpartum women, and otherwise healthy adults.

23_05_01 Hyman SMASH FISH.jpg
Omega-3 consumption is particularly important for ApoE4s. The following text and photo was posted recently on the Mark Hyman, MD page:
“I always tell people that if you can fit the entire fish in your pan, then it’s probably a good choice.
I like these types of small fish, SMASH fish: Salmon (wild caught), Mackerel, Anchovies, Sardines, and Herring.
You should eat seafood at least three times a week. The best fish are sustainably sourced, chock-full of omega-3s, low in contaminants and omega-6s, and certified authentic.
Much like our preference for vegetables, the fish that Americans love the most tend to be the kind that are the least nutritious, like tilapia and farmed catfish -- pale, mild-tasting varieties that are lowest in omega 3s.
Stay away from farmed seafood or wild fish that contain a lot of toxins -- larger fish are higher on the oceanic food chain, and as a result they accumulate more mercury, PCBs, and other toxins.
That’s why I don’t really eat swordfish, Chilean sea bass, halibut, and tuna. The toxins these big fish accumulate outweigh the benefits from their omega-3s.
As important as omega-3s are to every cell in our bodies, we’re not going to eat salmon and sardines every day. Some of us won’t eat those dark, oily fish ever.
So, it’s important to supplement with a daily fish oil. Taking a supplement of 1-2 grams a day is wise as it protects your cardiovascular system and reduces inflammation.”

23_06_29 hierarchy of scientific evidence.png
We post many papers here, but just because a paper is a scientific study (or that we post it) doesn’t mean the findings are indisputable. The type of study needs to be taken into consideration and even at the top of the pyramid, a critical eye needs to be applied. Just some things to consider, add your own in the comments. -- Was the paper peer-reviewed? Is there a good demographic sample? Is the timeframe of study adequate (remember Alzheimer’s develops over decades). Are the results stated as a percentage, percentages can make something appear more significant. Look at the scale on a graph, it can be manipulated to make an impact look greater than it really is. Is there direct causation or is there only association. Who funded the study, some are funded by industries who have a vested interest in the outcome. The pressure to publish or perish is great, bias and even fraud have made it in some studies.

Stress Rapidly Increases Biological Age, but Recovery Turns Back the Clock
The number 1 risk factor for Alzheimer's isn't ApoE4, but aging. Stress can cause rapid and transient increases in biological age, which can be reversed upon recovery, according to a new study. Using DNA methylation clocks, researchers found that stress triggers short-term fluctuations in biological age in humans and mice. The findings challenge the idea that biological age has a unidirectional upward trajectory over the life course, and highlights the importance of reducing biological age to improve longevity.

Nourishing the Mind: Nutritional Interventions to Slow Alzheimer’s Disease
A new systematic review examined nutritional interventions for Alzheimer’s disease (AD). The review identified 38 studies, including randomized clinical trials, systematic reviews, and meta-analyses.
The findings indicate that nutritional interventions such as the Mediterranean diet, ketogenic diet, omega-3 fatty acid supplementation, and probiotics may slow the progression of AD and improve cognitive function and quality of life in mild-to-moderate cases.

Diet and Dementia: Study Uncovers Gut-Brain Link to Alzheimer’s
1. The study found a significant correlation between 10 specific types of gut bacteria and the likelihood of developing Alzheimer’s disease. Six of these bacteria were identified as protective, while four were identified as risk factors for the disease.
2. Certain bacteria in the human gut can secrete acids and toxins that interact with the APOE gene, a major risk factor for Alzheimer’s disease, triggering a neuroinflammatory response that can affect brain health and immune functions.
3. The analysis revealed that an imbalance of gut bacteria can have negative effects on the immune system and is linked to various diseases, including depression, heart disease, cancer, and Alzheimer’s disease. This highlights the importance of maintaining a healthy balance of gut microbiota for overall health and disease prevention.

What I Eat In A Day: Functional Medicine Doctor Terry Wahls Tells All
Dr Terry Wahls is another favorite of ours for her great inspiration in overcoming a neurodegenerative disease. A former conventional medicine doctor who was diagnosed Multiple Sclerosis, she was provided the best traditional medicine had to offer, but she continued to decline becoming tilt-wheelchair bound as she no longer had the strength to hold herself up. She took to her own deep research in trying to find the root causes of her affliction. She used diet and lifestyle changes to restore her health and emerge from that wheelchair. She’s now a functional doctor and has helped many with various health concerns through her “Wahls Protocol”.

Icing Your Vagus Nerve: Does This TikTok Trend Really Work?
Link to article
https://healthnews.com/mental-health/se ... 2edKpxxmN8
Post
Key takeaways:
• The vagus nerve oversees the regulation of involuntary functions, and it acts as a pathway for sensory and motor signals between the brain and vital organs.
• Ice water face plunge, ice packs to the face, neck, or chest, and cold water splash are all ways that have been said to promote the activity of the vagus nerve and stimulate a calmer mind.
• Icing the vagus nerve is said to redirect the mind and shift the attention away from what was causing worry, anxiety, and stress, promoting a clear and refreshed mindset.
• Several studies promote the use of cold water therapy to activate the parasympathetic nervous system and promote everything from less stress to better sleep.

ApoE4 exacerbates the senescence of hippocampal neurons and spatial cognitive impairment by downregulating acetyl-CoA level
Link to paper
https://onlinelibrary.wiley.com/doi/ful ... 6o7BqVRHMs
Post
Although aging and apolipoprotein E (APOE) ε4 allele have been documented as two major risk factors for late-onset Alzheimer's disease (LOAD), their interaction and potential underlying mechanisms remain unelucidated. Using humanized ApoE4- and ApoE3- target replacement mice, we found the accumulation of senescent neurons and the activation of mTOR and endosome-lysosome-autophagy (ELA) system in the hippocampus of aged ApoE4 mice…. These data suggest that ApoE4 exacerbates neuronal senescence due to a deficiency of acetyl-CoA, which can be ameliorated by GTA supplement. The findings provide novel insights into the potential therapeutic value of GTA supplement for the cognitive improvement in aged APOE4 carriers.

The results were published August 30 in the journal Science Advances. The leader of the study is John Melchior, a protein biochemist at the Department of Energy’s Pacific Northwest National Laboratory. Melchior is a leader in lipoprotein research—and a carrier of two copies of the APOE4 gene, adding a personal incentive to his work to understand the protein’s action in the nervous system. From Melchior, “What the heck is APOE4 doing? That’s the big question. Why does one form translate to less risk for dementia while a slightly different form confers significant risk? Our technology brings us one step toward more answers.”

The ApoE4 allele presents a higher risk for Alzheimer’s but this risk is not a deterministic, some 4s get Alzheimer’s and some don’t. ApoE4 is also associated with cardiovascular disease, heightened immune response, arterial disorders of the brain, shortened longevity, among others. Maybe, we’re just not good agers. Although it’s a mouthful, “Antagonistic Pleiotropy Gene” might be better nickname for ApoE4. Antagonistic pleiotropy is a theory of aging and pleiotropic genes are those whose functions are beneficial to an organism's fitness early in life, but detrimental to its fitness later.

About 40% of the human brain is made up of gray matter and the other 60% is white matter. The gray matter, however, consumes about 94% of the total oxygen used by the brain. Gray matter is the areas where the actual "processing" is done whereas the white matter provides the communication between different gray matter areas and between the gray matter and the rest of the body.

Post:
ApoE4s are pro-inflammatory and studies have demonstrated that those with Alzheimer's disease and mild cognitive impairment tend to have higher levels of proinflammatory cytokines, cytokine receptors, and other inflammatory markers. This indicates that systemic inflammation plays a role in dementia pathogenesis. Diet can play a major role in keeping inflammation at bay. Thank you to Dr Jockers for this informative infographic, however one point of caution for ApoE4s is the recommendation for coconut foods as anti-inflammatory. They are also high in saturated fat and that raises lipids in ApoE4s moreso than our non-4 brethren. Similar caution when it comes to meat (not fish) consumption for ApoE4s, even if grass fed.

ApoE4s are a minority when it comes to general population and most studies/health recommendations are based on general population. Chances are your doctor is unfamiliar with the peculiarities that the ApoE4 allele confers, so take charge of your health.

Post:
Some say they don’t want to know their APOE status. But holding one or two ApoE4 alleles does not mean Alzheimer’s or the other health conditions associated with this genotype are assuredly in your future. If you understand the health weaknesses that being a 4 carrier brings and you make certain lifestyle adjustments accordingly, you greatly reduce your risks.

Statin Therapy Induces Gut Leakage and Neuromuscular Disjunction in Patients With Chronic Heart Failure
Post:
Full paper behind a paywall, but interesting enough to share the abstract since ApoE4s generally have high cholesterol numbers and doctors often seem to prescribe statins based solely on LDL without considering other markers or genetic status.
Patients taking statins experienced a significant increase in CAF22 (a marker of muscle wasting and sarcopenia), zonulin (a marker of intestinal barrier integrity), and C-reactive protein (a marker of inflammation). Statin patients also demonstrated reduced hand-grip and gait speed compared to those not taking statins. "...statin therapy adversely affects the neuromuscular junction and intestinal barrier, which potentially induces systemic inflammation and physical disability in patients..."

Gluten may cause brain inflammation, mouse study suggests
Post:
• In a groundbreaking study, researchers in New Zealand observed that wheat gluten can cause brain inflammation in mice.
• Their recent work showed that gluten added to a low- or high-fat diet triggered inflammation in the brain’s hypothalamic region, which regulates metabolism.
• Experts theorize that gluten may elicit an inflammatory immune response similar to what people with celiac experience.
• This research ties inflammation of nerve cells, to the onset of metabolic disease.
• Because mice and humans have similar systems, this study may carry important implications for human physiology.

NEWSFLASH: Chronic Ketosis is Not Your Goal
Post:
One of the most common misconceptions from folks trying to follow the Bredesen Protocol, which many ApoE4s do for prevention as well as treatment for cognitive issues, is the mistaken aspiration to remain in a state of chronic ketosis. These participants erroneously think they’ll need to dramatically restrict their carbohydrates and consume gobs of dietary fat for the rest of their lives! It’s time to set the record straight: Chronic ketosis is not the goal of the program. And if you think all keto diets are unhealthy, read the other blog written by Julie Gregory under the “education” link from September 14th, “Not Your Daddy’s Keto”.

Small HDL particles in brain appear protective against Alzheimer’s disease
Post:
Key takeaways:
• A gene (ApoE4) present in 25% of the population, which reduces neuroprotective small HDL production, is associated with increased Alzheimer’s disease risk.
• A drug in early development may be the key to lowering risk.

Post:
Butyrate is a beautiful thing. But what is butyrate? Butyrate is produced in your large intestine (colon) when “good” bacteria breaks down dietary fiber. What foods help generate butyrate? High fiber foods, resistant starches, fermented foods, and full fat dairy products (but watch the saturated fat if ApoE4, e.g. butter is 98% fat and over half the fat content is saturated fat). Graphic taken from
The paper, “Butyrate, neuroepigenetics and the gut microbiome: Can a high fiber diet improve brain health?” by Megan W Bourassa et al, 8 Feb 2016, Figure 2.

Surgery-free brain stimulation offers new hope for dementia treatment
Post:
Scientists have completed a successful human trial using new high-frequency technology to stimulate neurons in the hippocampus, the area responsible for forming, organizing and retrieving memories. This non-invasive, painless treatment is now being trialed in older individuals with cognitive impairment, as a potential way to improve memory loss and function caused by Alzheimer's disease and other forms of dementia.

LDL-C does not cause cardiovascular disease: a comprehensive review of the current literature
Post:
“For half a century, a high level of total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C) has been considered to be the major cause of atherosclerosis and cardiovascular disease (CVD), and statin treatment has been widely promoted for cardiovascular prevention. However, there is an increasing understanding that the mechanisms are more complicated and that statin treatment, in particular when used as primary prevention, is of doubtful benefit.”

Keto Diet Delays Alzheimer’s Memory Loss
Facebook comment:
A ketogenic diet significantly postpones the onset of Alzheimer’s-related memory decline in mice, a phase akin to human mild cognitive impairment preceding Alzheimer’s disease. Key findings highlight the molecule beta-hydroxybutyrate (BHB) as instrumental in this protective effect, showing a nearly seven-fold increase in mice on the diet and improving synaptic function critical for memory.

Facebook comment:
Yesterday we posted about research which identified 5 biological variants of Alzheimer’s disease through proteomic analysis of cerebrospinal fluid. This idea that Alzheimer’s disease is not a singular disease is not new. Although the variants are different, for a few years now, neurodegenerative disease researcher, Dr Dale Bredesen had already identified different types of Alzheimer’s.

24_02_09 Resistant Starch.jpg
Facebook comment:
Resistant starch, aka soluble fiber, can’t be broken down by digestive enzymes to be absorbed, so the unabsorbed molecules arrive in the intestines where the gut bacteria happily convert them to short-chain fatty acids (SCFAs). That’s a good thing! Examples of good resistant starches include: plantains, taro root, shirataki noodles, other nongrain “pastas,” parsnips, turnips, jicama, celery root, and Jerusalem artichokes (sunchokes), as well as UNRIPE fruits such as green bananas, mangoes, and papayas. Just watch the glycemic load, so consume judiciously.

New research suggests intermittent fasting increases the risk of dying from heart disease. But the evidence is mixed
Facebook comment:
Intermittent fasting has gained popularity due to reported health benefits. This is particularly applicable for ApoE4s trying to increase ketone production, lower basal insulin levels, and aid our impaired autophagy. But last week headlines suggested the practice could increase a person’s risk of death from heart disease. So what to make of these findings?
First, the research was presented as a scientific poster at an American Heart Association conference last week, the full study hasn’t yet been published in a peer-reviewed journal. The conclusion was based on observational research, not a controlled trial, and we don’t know if the authors controlled for other factors that can influence health, such as body weight, medication use or diet quality.

How A Neuroscientist Strengthens 5 Key Brain Regions Daily
Facebook comment:
From this article written by Daniel Amen, MD, “After 30-plus years as a psychiatrist who uses functional brain SPECT imaging in clinical practice, it is clear to me that the more you use your brain, the better it will perform. When most people think about mental exercise, they think about crossword puzzles and other word games. This is a great start, but it's only one piece of a total brain workout.
Based on the latest research as well as my own experiences in helping tens of thousands of patients optimize the brain and mental health, here are the best ways to exercise your brain on a daily basis.”

ApoE4s have higher risk for cardiovascular disease and are proinflammatory, so this is important to note. A new study published in the journal Nature Medicine identified a strong link between 4PY, a breakdown product from excess niacin, and inflammation of blood vessels. Niacin, also known as Vitamin B-3, is very common in Western diets.

Why Enhancing Metabolic Health Could be the Key to Preventing Alzheimer's Disease
Facebook comment:
Information rich, but easy to understand video where Dr. David Perlmutter, a neurologist, provides an in-depth exploration of a crucial but contentious topic in Alzheimer's research and treatment. For decades, the pharmaceutical industry has heavily invested in targeting beta-amyloid protein, a “hallmark" of Alzheimer's disease, as the primary approach to treatment. However, critics argue that focusing solely on beta-amyloid reduction is not only flawed but also poses potential risks, and has shown limited effectiveness in combating the actual progression of Alzheimer's. In contrast, a growing body of scientific research advocates for a paradigm shift towards preventing the disease by improving brain metabolism. This video reveals why enhancing metabolic health could be the key to truly combating and even preventing Alzheimer's, offering new hope and strategies for those affected or even at risk for this devastating disease.
