Background
The challenges of the COVID-19 pandemic extend to concerns about vaccine side effects, particularly potential links to neurodegenerative diseases such as Alzheimer's disease (AD).

Aim
This study investigates the association between COVID-19 vaccination and the onset of AD and its prodromal state, mild cognitive impairment (MCI).

Design
A nationwide, retrospective cohort study leveraging data from the Korean National Health Insurance Service was conducted.

Methods
The study, conducted in Seoul, South Korea, analyzed data from a random 50% sample of city residents aged 65 and above, totaling 558,017 individuals. Participants were divided into vaccinated and unvaccinated groups, with vaccinations including mRNA and cDNA vaccines. The study focused on AD and MCI incidences post-vaccination, identified via ICD-10 codes, using multivariable logistic and Cox regression analyses. Patients with vascular dementia or Parkinson’s disease served as controls.

Results
Findings showed an increased incidence of MCI and AD in vaccinated individuals, particularly those receiving mRNA vaccines, within three months post-vaccination.
The mRNA vaccine group exhibited a significantly higher incidence of

• AD (Odds Ratio [OR]: 1.225; 95% Confidence Interval [CI]: 1.025-1.464; p = 0.026) and
• MCI (OR: 2.377; CI: 1.845-3.064; p < 0.001)

compared to the unvaccinated group.
No significant relationship was found with vascular dementia or Parkinson’s disease.

Conclusions
Preliminary evidence suggests a potential link between COVID-19 vaccination, particularly mRNA vaccines, and increased incidences of AD and MCI. This underscores the need for further research to elucidate the relationship between vaccine-induced immune responses and neurodegenerative processes, advocating for continuous monitoring and investigation into the vaccines' long-term neurological impacts.

VitaminDWiki – Overview Alzheimer's-Cognition and Vitamin D contains:

• 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
  There are 13+ Alzheimer’s meta-analyses in VitaminDWiki
  There are 97+ Alzheimer’s studies in VitaminDWiki
  Dementia is associated with low vitamin D - many studies 50+ studies
  16+ studies in both categories Cognitive and Omega-3
