Hypertension will shrink the brain?

It is well known, high blood pressure easily lead to atherosclerosis, coronary heart disease, nephrotic syndrome, stroke and other serious complications. Some recent foreign reports, even if the long-term hypertension after taking effective antihypertensive drugs, but also can cause brain atrophy and lead to mental retardation, eventually forming dementia.

As early as 1984, Japanese scholars through the CT scan had found that elderly patients with hypertension are signs of brain atrophy. Now researchers using more sophisticated magnetic resonance imaging device, to have 10 patients with a history of hypertension, high blood pressure and the same age without the health check to the control group, each measured brain tissue three images and the percentage of ventricular cavity, the results show that Long-term patients with hypertension increased ventricle, the brain narrow. The researchers analyzed that this may be due to long-term high blood pressure in patients with cerebral artery thickening of the brain reduced blood flow, causing some nerve cells and brain tissue damage caused by. After a period of time, with age, brain atrophy will increase.

Patients with hypertension because of more severe brain atrophy, will significantly decrease the level of intellectual, language barriers function will occur. Such as the recent U.S. National Institute of Aging scientist, the MRI showed that with the growth of aging, high blood pressure in patients with temporal lobe in the brain and neck side of the ring, the two parts of the brain tissue loss of more than healthy people. The brain in these two positions in human memory and language function plays an important role. Inspection also found that even rely on medication to control high blood pressure, the two parts of the organization will continue to damage the brain, and hypertensive patients and healthy people in other parts of the brain differences are not.

Intelligence test results and MRI results reached the same conclusion, high blood pressure in patients with mental decline significantly faster in healthy people. Scientists had previously found that, in addition to the normal process of aging, high blood pressure will also shrink the brain. Now it seems that it would aggravate high blood pressure of the aging brain.

The scientists conducted the study also showed that older patients with hypertension (70 to 84 years) than younger patients with hypertension (56 to 69 years) and healthy brain tissue loss should be more, the former intelligence level it was obvious Lower.

Therefore, patients with hypertension should Zunyi Zhu, long-term regular use of antihypertensive drugs, and under the condition to improve with the use of brain function and brain cell cycle activation of drugs, such as the brain benefits triazine, brain rehabilitation, the brain-new, live-such as the brain. At the same time, attention to non-drug therapy, such as day-to-day with low-salt, low fat, low cholesterol diet-based, smoking cessation Jijiu, appropriate exercise, weight control, prevent and emotional fatigue, and ensure adequate sleep, and more fresh fruits and vegetables, Vegetable oil, to combat brain atrophy and dementia.
