Alzheimer's disease is one of the main reasons for the disability of the elderly in the world. With the increase of age, it 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) in Australia may make this idea a reality -new genetic studies have shown that dementia and vitamin D lacks a direct connection.

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

After investigating the association of vitamin D, neural imaging characteristics and dementia and stroke risks, researchers found that low -level vitamin D is related to low brain capacity and increased dementia and stroke risks. Cause and effect; among some people, raising people's vitamin D levels to normal levels (50nmol/L) can prevent up to 17%of dementia.

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 dementia and stroke.

Non -linear Montel random (MR) -n a method that uses measurable genetic mutation to check variable exposure to the impact of the cause and effect of the disease -the potential causal relationship between the results of neurological imaging, dementia, and stroke.

Elina Hyppönen, director of the UNISA Australia precision health center, said that these discoveries are important to prevent dementia and understand the lack of vitamin D.

"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 the effects of extremely low -level vitamin D on dementia and stroke risks.

"In the case of the lack of vitamin D, our discovery is of great significance to prevent the risk of dementia. In fact, in the British population analyzed, we observe that to increase the level of vitamin D to the normal range, we can avoid As many as 17%of dementia occur, "Hyppöneen said.

Memorosis is a chronic or performed syndrome that causes deterioration of cognitive function.

About 487,500 Australians suffer from dementia, which is the second largest death in the country.

More than 55 million people in the world suffer from dementia, and 10 million new cases are diagnosed each year.

Considering the high incidence of dementia 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.
