Wood JM, Gupta S.
- Overview Alzheimer's-Cognition and Vitamin D has the following summary
- FACT: Cognitive decline is 19X more likely if low vitamin D
- FACT: Dementia is associated with low vitamin D levels.
- FACT: Alzheimer’s Dementia 2.3X more likely in elderly if low vitamin D – Dec 2022
- FACT: Dementia is associated with low vitamin D - many studies
- FACT: Alzheimer's Disease is 4X less likely if high vitamin D
- FACT: Every single risk factor listed for Alzheimer's Disease is also a risk factor for low vitamin D levels
- FACT: Elderly cognition gets worse as the elderly vitamin D levels get even lower (while in senior homes)
- OBSERVATION: Reports of increased vitamin D levels result in improved cognition
- OBSERVATION: Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
- OBSERVATION: Alzheimer's Disease has been seen to halt when vitamin D was added.
- OBSERVATION: Alzheimer’s is associated with all 7 of the genes which restrict vitamin D
- OBSERVATION: 39 vitamin D and Alz. or Cognition intervention trials as of Sept 2018
- OBSERVATION: 2 Meta-analysis in 2012 agreed that Alzheimer's Disease. associated with low vitamin D
- OBSERVATION: 50X increase in Alzheimer's while decrease in vitamin D
- OBSERVATION: Vitamin D reduces Alzheimer’s disease in 11 ways
- OBSERVATION: Alzheimer’s cognition improved by 4,000 IU of vitamin D
- OBSERVATION: Plaque removed in mice by equiv. of 14,000 IU daily
- OBSERVATION: DDT (which decreases Vit D) increases risk of Alzheimer's by up to 3.8X
- OBSERVATION: 2% of people have 2 copies of the poor gene reference: Alz Org
- OBSERVATION: Genes do not change rapidly enough to account for the huge increase in incidence
- OBSERVATION: End of Alzheimer's videos, transcripts and many studies protocol has been very successful
- It adjusts Vitamin D, B-12, Iron, Omega-3, food, etc, and can now be done at home. $75/month.
- FACT: Vitamin D is extremely low cost and has very very few side effects
- CONCLUSION: Everyone concerned about cognitive decline or Alzheimer's Disease should take vitamin D
- PREDICTION MET: By 2024 Omega-3 and high dose Vitamin D will be found to reverse Alzheimer's in humans

BACKGROUND:
According to the Alzheimer's Disease 2014 Facts and Figures report, an estimated 5 million older Americans are living with Alzheimer's disease (AD). AD is the sixth leading cause of death in the United States and the only 1 among the top 10 that cannot be prevented, cured, or even slowed. Predictably, AD puts an enormous cost burden on the U.S. health care system, with costs expected to soar to $1.2 trillion in 2050. Many individuals with minor cognitive impairment do not seek treatment and/or delay treatment until perceptible deficits indicative of moderate stage of disease are present. Several new drugs for AD are under development based on etiological disease theories, but their long-term impact on cognition and/or function is unclear. One potential treatment is to address low serum 25-hydroxy vitamin D (25[OH]D).
METHODS:
We performed a literature review on the topic of low vitamin D levels and cognition in geriatric patients.
RESULTS:
Recent studies have associated low vitamin D levels with cognitive complaints, impairment, and AD in geriatric patients; however, there is a dearth of prospective studies on the topic.
CONCLUSIONS:
Available data suggest that more research is needed to promote a better understanding of vitamin D levels and incident AD.
