Mutated gene, OAS1, which lowers vitamin D in brain, increases Alzheimers and severe COVID-19 – Oct 2021

Overview Alzheimer's-Cognition and Vitamin D starts with

• 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
• 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: By 2024 Omega-3 and high dose Vitamin D will be found to reverse Alzheimer's in humans
  • As of 2018 that combination has worked well with Multiple Sclerosis, Sleep, and Cluster Headaches
  
  There are 12+ Alzheimer’s meta-analyses in VitaminDWiki
  There are 84+ Alzheimer’s studies in VitaminDWiki
  Dementia is associated with low vitamin D - many studies 50+
  48 studies in both categories Cognitive and Omega-3 see below
  The End of Alzheimer's - if custom adjust Vitamin D, B-12, Iron, Omega-3, etc.
     Customizing the types of treatment to the individual results in reversing Alzheimer's
