Overview Alzheimer's-Cognition and Vitamin D

A summary of the key points of this page by Claude2 - July 2023

The PDF provides an overview of the evidence linking vitamin D deficiency to increased risk of Alzheimer's disease and cognitive decline. It highlights numerous studies, facts, and observations supporting vitamin D's role in brain health.

Some key facts presented:

  • Cognitive decline is 19 times more likely with low vitamin D levels.
  • Dementia and Alzheimer's diseases are consistently associated with low vitamin D in many observational studies.
    • Alzheimer's is 2.3 times more likely in the elderly with low D.
  • Every single risk factor for Alzheimer's disease is also a risk factor for low vitamin D.
  • As vitamin D levels in the elderly continue to decline, cognition gets worse.
  • Increasing vitamin D has been observed to improve cognition in some reports.
  • Alzheimer's patients are 3 times more likely to have a malfunctioning vitamin D receptor gene which can prevent vitamin D from getting into cells.

Some key observations:

  • In animal studies, vitamin D has been found to help remove amyloid brain plaque associated with Alzheimer's.
  • Exposure to DDT, which decreases vitamin D, increases Alzheimer's risk by up to 3.8 times.
  • Genes linked to Alzheimer's all also restrict vitamin D function.
  • There are at least 11 ways vitamin D may help reduce Alzheimer's disease risk and pathology.
  • Daily vitamin D supplementation around 4,000 IU improved cognition in Alzheimer's patients in a clinical trial.

In summary, the PDF compilation of references indicates substantial evidence for a link between low vitamin D and increased Alzheimer's and cognitive decline. It advocates vitamin D supplementation as a low-risk, low-cost prevention and treatment strategy. Combining vitamin D with omega-3 is highlighted as another promising approach currently being tested.

Vitamin D in Alzheimer's Disease: Low Levels in Cerebrospinal Fluid Despite Normal Amounts in Serum
J Alzheimers Dis. 2022 Feb 15. doi: 10.3233/JAD-215536
Jelena Zugic Soares 1 2 3, Jørgen Valeur 3, Jūratė Šaltytė Benth 4 5, Anne-Brita Knapskog 6, Geir Selbæk 2 6 7, Golchin Arefi 8, D Gregor Gilfillan 8, Anita Tollisen 3, Nenad Bogdanovic 6 9, Renate Pettersen 1

Background: Vitamin D insufficiency has been suggested as a dementia risk factor.

Objective: In this cross-sectional, explorative study we investigated whether levels of vitamin D in cerebrospinal fluid (CSF) are lower in patients with positive biomarkers of Alzheimer's disease (AD) compared to cognitively healthy controls and whether polymorphisms of the vitamin D receptor (VDR) gene, FokI, BsmI, ApaI, and TaqI, are associated with levels of vitamin D in CSF and cognition.

Methods: We included 100 patients≥65 years assessed for cognitive impairment and 76 cognitively healthy controls. Levels of 25-hydroxyvitamin D (25(OH)D) in both serum and CSF, and VDR polymorphisms were analyzed.

Results: The mean level of 25(OH)D in serum was 78.6 (SD 28.9) nmol/l. While serum levels of 25(OH)D were not significantly different between the groups, CSF levels of 25(OH)D were significantly lower in patients with positive AD core biomarkers (p = 0.001) compared to patients without such biomarkers. Individuals with the BsmI major homozygote genotype had significantly lower results on a 10-word delayed recall test (p = 0.044) and verbal fluency test (p = 0.013), and individuals with the TaqI major homozygote genotype had significantly lower results on a verbal fluency test (p = 0.030) compared to individuals with the corresponding minor homozygote genotype.

Conclusion: Patients with positive AD core biomarkers have low CSF levels of 25(OH)D, despite sufficient serum levels. CSF levels of 25(OH)D do not seem to be affected by any of the four VDR gene polymorphisms. TaqI and BsmI major homozygote genotypes might be at increased risk for development of cognitive decline.

  • From Fight Aging On Increasing Your Chances of Avoiding Alzheimer's July 2011
    In many ways, Alzheimer's Disease looks a lot like type 2 diabetes - it can be argued that there are some biochemical similarities in the underlying mechanisms, Alzheimer's appears to be a lifestyle disease to some degree, and the two conditions have many of the same risk factors, such as obesity and being sedentary. So: " Over half of all Alzheimer's disease cases could potentially be prevented through lifestyle changes and treatment or prevention of chronic medical conditions. ...
    Analyzing data from studies around the world involving hundreds of thousands of participants, [researchers] concluded that worldwide, the biggest modifiable risk factors for Alzheimer's disease are, in descending order of magnitude, low education, smoking, physical inactivity, depression, mid-life hypertension, diabetes and mid-life obesity. ...

In the United States, [researchers] found that the biggest modifiable risk factors are

  • physical inactivity,
  • depression,
  • smoking,
  • mid-life hypertension,
  • mid-life obesity,
  • low education and
  • diabetes. ...

Fig. 2. Proposed mechanisms of vitamin D-mediated multitargeted effects in AD. Vitamin D imbalance is proposed to alter mechanisms implicated in aging and AD pathogenesis. Suggested protective effects of vitamin D supplementation concern regulation of vascular processes and oxidative stress, calcium homeostasis, neurotransmission, modulation of immune and inflammatory processes, and direct impact on amyloidogenesis, ultimately improving cognitive functions.

APOE4 gene greatly increases the risk of AD, but had been a benefit during childhood

The APOe4 gene protected our ancestors and helped them get through the childbearing years by attacking parasites and micro-organisms with oxidative stress. It is only in modern times that people live long enough for the same oxidative stress to work against us in old age.
A book, Survival of the Sickest,(2008) points out roughly the same concept in a number of other diseases which long ago helped our ancestors get through plagues, ice ages, parasites, famine, etc. It's a fascinating concept and it makes sense. By Rich H, Jan 2017

Why Is Modern Medicine Aiming To Reduce Risk For Alzheimer's Disease With Expensive Gene Editing Technology When Fish Oil, Antioxidants & Metal Chelation Are More Effective & Economical? Bill Sardi

  1. The alternative therapies cancel the increased risk of Alzheimer's due to gene problems
    Gene Therapy ignores the other causes of Alzheimer's and other forms of dementia
  2. The alternative therapies are far far less costly than gene therapy
    might cost $200 Billion to provide gene therapy to everyone with the APOE-4 gene problem

60% reduced decline in moderate Alzheimer's symptoms by just diluting blood with water - Feb 2024

Can Getting Transfusions of Young Blood Slow Aging? Dr. Greger video
Vampires 2.0? The ethical quandaries of young blood infusion in the quest for eternal life.” In an episode of the TV series Silicon Valley entitled “The Blood Boy,” a tech guru hires a young assistant from whom to transfuse pints of blood in an attempt to slow down his aging. The restoration of youth by bathing in or drinking the blood of youth is a centuries-old trope dating back at least to the futile attempt of ailing Pope Innocent VIII, who in the 1490s failed to live up to his name by apparently drinking the blood of three ten-year-old boys who—though a bargain “costing only one ducat apiece’’—died in the process.

Might there be something to it, though? Though young blood did not have a significant impact on lifespan otherwise, infusing the blood of young animals into old did have rejuvenating effects on multiple organs, similar to full-blown parabiosis, as I talked about in the last video. In fact, not only does the infusion of young mouse blood improve age-related cognitive dysfunction in old mice, young human blood—taken from umbilical cords—worked too (in mice engineered to not reject the foreign tissue). This led to ongoing clinical trials offering weekly infusions of blood products from young donors to patients with mild to moderate Alzheimer’s disease. But there may be an easier way.

Yes, the injection of blood from young mice into old can improve memory and learning, suggesting there’s some kind of restorative youth factor. But the injection of blood from old mice into young can worsen memory and learning, suggesting that instead there’s some sort of debilitating aging factor. Or maybe the old blood is just diluting the revitalizing factor in the young mouse. Or, for that matter, maybe the young blood is diluting the debilitating factor in the old mouse. The fact that old blood appears to make things worse more than young blood makes them better suggests maybe the latter is the case. But you don’t know until you put it to the test.

Ready for a mind-blowing shift in perspective? Instead of infusing young blood into old mice, researchers at UC Berkeley just diluted the blood of old mice by siphoning off the plasma (the liquid portion of the blood), and essentially replacing half of it with water. If the regeneration seen in heterochronic parabiosis and blood transfusions was due to some fountain of youth factor in young blood, then nothing should happen, right? But if all the young blood was doing was diluting some debilitating aging factor, then the water should work just as well. And it did. The rejuvenation in the liver was similar to parabiosis or transfusion, and in the muscles and the brain, it was even better. So, most, if not all, the benefits could be replicated by simple dilution, including an improvement in cognitive capacity.

That’s good news, since there’s already an FDA-approved procedure in use today known as therapeutic plasma exchange. It’s usually used to filter out toxins or autoimmune antibodies, but why not try using it to try to dilute old blood to treat Alzheimer’s disease? And that’s exactly what researchers did.

Hundreds of Alzheimer’s patients were randomized to a therapeutic plasma exchange procedure or a placebo (sham) procedure. And though it didn’t seem to help those with mild Alzheimer’s disease, those with moderate Alzheimer’s randomized to the real procedure experienced about 60 percent less cognitive and functional decline over a period of 14 months. This is in stark contrast to mainstay treatments for Alzheimer’s, like the drug memantine, that can help with symptoms but don’t actually alter the course of the disease. And the added advantage over blood transfusions, as a Director of an Institute of Biomedical Ethics put it: “There is something peculiar about the old literally feeding on the young.”
