Thus the results of the research were presented at the 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, USA, the researchers analyzed cardiac health and cognitive abilities of 1,200 people aged 70 years. The study was conducted since 1948. Measurements 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. While those who do light exercise have a greater risk of developing the disease, especially in men.
"This is a study with a large scale and long period. In conclusion, exercise, minimal in the medium intensity, effectively reducing the risk of dementia," said Dr Zaldy Tan, from Brigham and Women's Hospital, Boston.
In the second study, researchers in the United Kingdom analyzed 3,325 people aged 65 years and over who participated in the National Health and Nutrition Examination Survey National Third in America. The study refers to the amount of vitamin D measurement with cognitive abilities.
The researchers took blood samples respondent sample is then compared with cognitive functions that include tests of memory, orientation space and time, as well as the ability of concentration of attention. For those who have a value below 10 percent classified as suffering from cognitive impairment.
They are deficient in vitamin D, 42 percent higher risk of developing dementia and those with an acute shortage of vitamin D, the risk is 394 percent higher.
"It seems that the possibility of higher levels of cognitive impairment are assumed to lack of vitamin D, is consistent with the findings of previous European research," said David Llewellyn, of the University of Exeter Peninsula Medical School.
Naturally, the skin produces vitamin D when exposed to sunlight. However, the majority of American adults are deficient in vitamin D because the skin less productive in producing vitamin D due to aging and limited sun throughout the year.
If the requirement of vitamin D is not met from food and drinks, it is advisable to take vitamin D supplements available on the market. "Vitamin D supplementation has been shown to be a safe, inexpensive and effective way to treat deficiency of vitamin D deficiency," said Llewellyn.
