Russian biologists have found the possible causes of hypertension, which is characterised as a persistent increase in blood pressure, and a corresponding study has been published in the journal “Experimental Physiology,” according to the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences.
The scientists observed that changes in nervous system activity and blood flow in the brain, both occurring at a young age, could be possible reasons for the development of hypertension.
Such a conclusion was reached by comparing two groups of rats. The first group had normal blood pressure while the second had anomalous ones that developed over a period of four to six weeks from birth and remained characteristic throughout their future lives.
The rodents in the second group, when compared to the first, showed changes in blood flow in certain arteries as well as changes in brain activity, in particular a decrease in the prefrontal cortex and an increase in the hypothalamus region. An estimated 90-95% of people show no clearly observable causes of high blood pressure. Meanwhile, hypertension is a risk factor for diseases of the brain, kidneys, heart, eyes and other organs.
