Alzheimers-Cognition - Overview 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 21 % more likely if low vitamin D
- FACT: Alzheimer's Disease is 4X less likely if 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: 39 vitamin D and Alz. or Cognition lntervention 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
- 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

290 Cognitive category starts with the following
Very brief summary of Cognitive decline
Treatment : Vitamin D intervention slows or stops progression
Prevention : Many observational studies - perhaps Vitamin D prevents
Omega-3 both prevents and treats cognition
