Scientists found that vitamin D deficiency increases the risk of dementia by 51%

Dementia, or acquired mental retardation, is a persistent decline in cognitive activity with the loss of previously acquired knowledge and practical skills. It develops as a result of disease or damage to the brain after its maturation is complete.

Research has shown that vitamin D deficiency increases the risk of developing Alzheimer's disease, the most common form of dementia, by more than 50%.

Scientists conducted a meta-analysis of 16 different studies on the relationship between vitamin D and dementia. The presence of a connection between the lack of this vitamin in the body and the risk of developing dementia was confirmed in 32% of cases, Alzheimer's disease – in 34%.

A significant deficiency of vitamin D increases the likelihood of Alzheimer's disease by 51%, while an increase in the amount of this vitamin to a level capable of protecting the brain from the loss of cognitive functions with aging.

At the same time, researchers admit that the exact mechanism that determines the effect of vitamin D on the development of dementia is not yet clear.
