Lack of this kind of vitamin may suffer from Alzheimer's disease

Alzheimer's disease is one of the main causes of disability in the world. As he grows, he will also affect thinking and behavior.

Can it prevent the development of this degenerative disease? A world's first study at the University of South Australia (UNISA) may make this idea a reality -new genetic studies have shown that Alzheimer's disease is directly related to vitamin D.

Recently, related studies were published in the "Journal of Clinical Nutrition".

After investigating the association of vitamin D, neural imaging characteristics and Alzheimer's disease and stroke risk, researchers found that low -level vitamin D is related Analysis supports the causal relationship between vitamin D deficiency and Alzheimer's disease; among some people, the level of people's vitamin D levels is raised to normal levels (50nmol/L), which can prevent up to 17%of Alzheimer's disease.

This genetic study analyzed the data of 29,4514 participants in British Biological Bank, and studied the influence of low -level vitamin D (25nmol/L) and the risk of Alzheimer's disease and stroke.

Non -linear Montel Randoming (MR) -n a method of using measuring gene mutation check on the impact of variable exposure on the cause and effect of disease -being used to test the results of neurological imaging, Alzheimer's and stroke potential causal relationship Essence

Elina Hyppönen, director of the UNISA Australia's precision health center, said that these discoveries are very important for preventing Alzheimer's disease and understanding of eliminating vitamin D deficiency.

"Vitamin D is a hormonal precursor, and people are increasingly realized that it has a wide range of influences, including the impact on brain health."

For the first time, the study analyzed a large number of people, and studied the impact of extremely low -level vitamin D on Alzheimer's disease and stroke risks.

"In the absence of vitamin D, our discovery is of great significance to prevent the risk of Alzheimer's disease. In fact, in the British population analyzed, we have observed that the level of vitamin D is raised to the normal range. You can avoid up to 17%of Alzheimer's disease, "Hyppöneen said.

Alzheimer's disease is a chronic or performed syndrome that causes deterioration of cognitive function.

About 487,500 Australians suffer from Alzheimer's disease, which is the second largest death in the country.

More than 55 million people in the world suffer from Alzheimer's disease, and 10 million cases were diagnosed each year.

Considering the high incidence of Alzheimer's disease around the world, this discovery is of great significance.

"By eliminating the phenomenon of serious lack of vitamin D, we can make thousands of people healthy." Hyppöneen said, "Most people may have no problem, but those who cannot obtain sufficient vitamin D from the sun for some reason for some reasons are For example, adjusting the diet may not be enough, and it is necessary to supplement vitamin D.
