Abstract in brief

  • Vitamin D deficiency is linked to a higher risk of dementia, Alzheimer's disease (AD), and cognitive impairment, with deficient individuals showing about 1.4 times the risk.
  • The study suggests that maintaining a vitamin D level around 75-100 nmol/L might be optimal to reduce dementia risk, with levels above 40 nmol/L potentially lowering AD risk.
  • The relationship between vitamin D levels and dementia risk is nonlinear, meaning the benefit of increasing vitamin D varies at different levels, highlighting the importance of finding the right dose for prevention.
