According to a report on June 14 by the US Daily Science website on June 14, the latest genetic research shows that there is a direct link between dementia and vitamin D deficiency.
The study investigated the link between vitamin D, neuroimaging features, and the risk of dementia and stroke. Dementia is a chronic, progressive syndrome that causes cognitive decline. More than 55 million people worldwide suffer from dementia, with 10 million new cases diagnosed each year.
The genetic study, supported by Australia's National Health Care Research Council, analysed data from 294,514 participants from the UK Biomedical Bank on the impact of low vitamin D levels (25 nmol/L) and the risk of dementia and stroke. Risks were studied. The researchers used nonlinear Mendelian randomization to conduct experiments to investigate potential causal relationships between neuroimaging outcomes, dementia and stroke.
Senior researcher Professor Elina Huppening, director of the Australian Centre for Precision Medicine at the University of South Australia, said the findings have important implications for preventing dementia and recognising the need to correct vitamin D deficiency.
Professor Xu Pening said: "Vitamin D is a hormone precursor that is increasingly being recognised for its wide-ranging effects, including on brain health. However, until now, it has been important to investigate what happens to vitamin D deficiency. As a result, it has always been a problem.”
"In some cases where vitamin D deficiency is relatively common, our findings have important implications for dementia risk," said Huperin. In fact, we found that as many as 17 percent of Dementia cases may be avoided by raising vitamin D levels within the normal range."
"Most of us are probably fine, but for those who don't get enough vitamin D from sun exposure, dietary adjustments may not be enough, and supplementation may be needed," says Huperin.
