Intensive control of blood pressure, benefits the brain

Intensive blood pressure treatment does not have an effect for at-risk patients, only a positive effect on the cardiovascular system, but also on the brain. This could help to preserve brain power in old age longer.

On the basis of MRI brain scans, researchers from the U.S. institutes of Health (NIH), the blood pressure of several hundred participants, the impact on the state of your brain. In patients receiving a standard treatment against high blood pressure, showed more damage in the cerebral white matter than patients who were intensively controlled. These results, which were published in the Journal of the American Medical Association, complement the previous study by the same research group. At that time she had already demonstrated that intensive treatment reduced the likelihood of mental impairments.

"These first results do not support a growing number of Point out that the control of blood pressure diseases the risk for stroke and heart, but also an age-related loss of mental capacity verringert", Dr. Walter J. Koroshetz, Director of the National Institute for neurological disorders and stroke at the NIH said. He urges that, to monitor blood pressure and to optimise them where necessary.

The SPRINT study (Systolic Blood Pressure Intervention Trial) was launched in 2010 and is used to compare the effects of Standard and intensive blood pressure control on cardiovascular health and mortality. More than 9,300 adults with a high risk for cardiovascular disease over the age of 50 years were given either a standard treatment, which lowered the systolic blood pressure to less than 140 mmHg, or an intense treatment, wherein the target value to a maximum of 120 mmHg was. In August 2015, the study was terminated earlier than planned, after initial results had shown that a 3.3-year-old intensive treatment rates, mortality, and the Occurrence of cardiovascular reduced diseases significantly. Brain scans were taken of 449 participants at the beginning of the study and again after four years.
