Experts from the University of Arizona found that people with high body mass index in old age are more likely to suffer from memory loss, disorders of attention and reduce the level of intelligence in General. According to the researchers, this suggests that obesity or just excess weight can provoke a decrease in cognitive abilities.
The body mass index, or BMI — a ratio of weight in kilograms to the square of his height in meters. Despite the fact that this figure is not everyone recognizes the perfect, it is actively used in order to determine whether the person is suffering from overweight and obesity (or, conversely, from the lack of weight). During their study, researchers tried to find out whether there is a relationship between the BMI of the elderly, and status of their brain.
Scientists have used data collected in aggregate about 21,5 thousand people in the course held earlier in the UK long term research. This data covered 12 years of the life of British people over the age of 50 years. As it turned out, participants with a high body mass index in the nervous system proceeded faster inflammation affecting many aspects of thinking. The researchers suggest that this plays a role contained in the blood plasma C-reactive protein.
The specialists emphasize that a decline in cognitive abilities is not the most joyful, but almost an inevitable consequence of aging, even if we are talking about a healthy person with ideal weight. The researchers also emphasize that to call a proven negative impact of excess weight on intelligence on the findings of the studies is impossible, because it is premature to assert that the relationship between these two factors is causal. One way or another, experts recommend that people monitor their weight, because, regardless of the results of this particular study, the maintenance of its normal useful for health in many aspects.
