People who have adequate vitamin D levels in their bodies, tend to be spared from senile dementia or Alzheimer’s disease in old age. In addition to sufficient vitamin D levels, remains to be coupled with regular exercise activities.
Thus the results of research presented at an international conference on Alzheimer’s disease in Hawaii, USA. Alzhemair or dementia often occurs in people above the age of 60 years.
In a study conducted in the town of Framingham, U.S. researchers analyzed heart health and cognitive abilities of 1,200 people aged 70 years. Research was conducted since 1948. Measurement of physical exercise has been carried out in 1986-1987.
After more than two decades of 242 respondents had dementia, including 193 cases of Alzheimer’s.
Those who exercise with moderate to severe intensity, the risk of dementia was reduced by 40 percent.Meanwhile, those who do little exercise have a greater risk of disease, particularly in men.
“This is a study of large-scale and long period. In conclusion, exercise, a minimum in the intensity of the medium, effectively reducing the risk of dementia,” says Dr. Zaldy Tan, of Brigham and Women’s Hospital, Boston.
In the second study, researchers in the United Kingdom analyzed the 3325 people aged 65 years and over who participated in the Health and Nutrition Examination Survey National Third in the Americas. The study refers to the amount of vitamin D measurement of cognitive ability.
The researchers took samples of blood sample respondents and compared with tests of cognitive function including memory, orientation space and time, and the ability of recollection. For those who have a score below 10 percent were classified as suffering from cognitive disorders.
Those who experience vitamin D deficiency, 42 percent higher risk of dementia and those exposed to vitamin D deficiency, acute risk is 394 percent higher.
“It seems likely increase in the level of cognitive impairment is assumed to lack of vitamin D, consistent with the findings of previous European studies,” said David Llewellyn, from the University of Exeter Peninsula Medical School.
Naturally, the skin will produce vitamin D when exposed to sunlight. However, the majority of American adults lack of vitamin D because the skin is less productive in producing vitamin D caused the aging and limited sun throughout the year.
If vitamin D requirements are not met from food and beverages, are advised to take vitamin D supplements are available on the market. “Vitamin D supplements have been proven to be a safe, cheap and effective way to treat deficiency of vitamin D deficiency,” said Llewellyn.
