"A potential association between COVID-19 vaccination and development of Alzheimer's disease"
Excerpt: "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."
