Study Finds Supplements Do Not Ward Off Dementia

Higher levels of a chemical called homocysteine are believed to raise the risk of strokes and dementia, and vitamin B12 and folic acid lower homocysteine levels, leading researchers to investigate B12 and folic acid supplements as a possible means of preventing dementia. However, the results of a recent study found no difference in memory and thinking skills between those taking the supplements and those taking a placebo, suggesting that these supplements have little to no protective effect when it comes to dementia.

Vitamin D Deficiency Linked to Dementia

Older adults with severe vitamin D deficiency have an increased risk of developing dementia, a recent study has found. This does not necessarily mean that vitamin D deficiency is a cause of dementia, as it is also possible that another unknown factor could cause someone to have both low vitamin D levels and dementia. Further study is needed to determine the nature of the relationship between vitamin D and dementia, but if it is indeed found to be a causal relationship, it could mean that simply eating more vitamin D-rich foods or taking supplements could reduce dementia risk in later life.
