Abstract in brief

The meta-analysis found that people with vitamin D deficiency (25OHD level below 50 nmol/L) have a 21% higher risk of developing Alzheimer's disease and dementia compared to those with adequate vitamin D levels.
The results suggest a significant link between low vitamin D levels and increased risk of these neurological conditions, with no major variation among the included studies.
Further research is needed to confirm these findings and to determine if vitamin D supplements can help prevent Alzheimer's and dementia.]
