Aboriginals of the Amazonian Tribe Timman brain is older than the inhabitants of the United States and Europe, which is expressed in a slower decrease in the volume of the brain and, most likely, in the low risk of cognitive violations and dementia. The secret of longevity lies in the traditional lifestyle of the Indians. This conclusion came scientists at the University of Southern California, whose article was published in The Journals of Gerontology, Series A. Briefly about the study tells the Edition of Science Alert.
It was believed that tumans that do not receive modern medical care are at high risk of infectious diseases and, as a result, frequent inflammation. In turn, systemic inflammation leads to enhanced brain atrophy. At the same time, the Timan found the lowest indicators in the world in the development of coronary heart disease due to an active lifestyle and low-calorie diet.
746 Timis took part in the study between the ages of 40 and 94, which they conducted computed tomography. They had a slower reduction in the volume of the brain compared with the groups of tests from Germany, the USA and the Netherlands. Thus, the state of the cardiovascular system turned out to be more important for healthy aging of the brain than inflammation factors associated with infectious diseases.
In general, the modern lifestyle is accompanied by an increase in the rate of reducing the volume of the brain by about 70 percent, depending on age.
