Vitamin D deficiency may increase the risk of dementia in light-skinned people by 25%. This has been shown by a study published in the journal. American Journal of Clinical Nutrition (AJCN).
Scientists analyzed medical data collected over 12-17 years from 270 thousand people aged 55-69. Of these, close to 20% reported regularly taking vitamin D supplements, but 34.0% and 18.3% were found to be deficient and deficient (severe deficiency), respectively.
Further analysis showed that the overall risk of dementia (including Alzheimer’s disease or vascular dementia) was 19-25% higher in cases of vitamin D deficiency. Interestingly, neither vitamin D deficiency nor vitamin D deficiency was associated with dementia risk in black participants.
Dementia manifests itself as severe memory and thinking impairment and develops in almost 10% of the population over the age of 60. There is no cure for this condition and the mechanisms of its development are unknown. Previous studies have shown that vitamin D deficiency may increase the risk of dementia. The new study confirms this, but because it is observational in nature, it does not prove a cause-and-effect relationship.
