Vitamin found that reduces the risk of Alzheimer's disease

Scientists have discovered a link between vitamin D levels in middle age and a reduced risk of neurodegenerative changes in the future.

As reported by BAKU.WS with reference to a foreign publication, the results of a study published in Neurology Open Access showed that people with higher vitamin D levels are less likely to encounter signs of Alzheimer's disease later in life.

The study involved 793 people with an average age of about 39 years. In the first phase, scientists determined the concentration of vitamin D in the blood, and approximately 16 years later conducted MRI scans to assess the accumulation of proteins associated with dementia — tau and beta-amyloid.

The analysis showed that participants with higher vitamin D levels had less tau protein, which is considered one of the key markers of the disease. At the same time, no association with beta-amyloid was found. When processing the data, researchers took into account additional factors, including age, sex, and the presence of depressive symptoms.

The authors emphasize that this is a statistical association, not a direct cause-and-effect relationship. Nevertheless, according to international experts, vitamin D levels may be considered a potentially controllable factor influencing the risks of developing dementia.
