Study: Low Blood Pressure May Weaken Brains of Some Heart Patients
People suffering from cardiovascular disease who have lower-than-normal blood pressure may face a higher risk of brain atrophy -- the death of brain cells or connections between brain cells, Dutch researchers report.
Such brain atrophy can lead to Alzheimer's disease or dementia in these patients. In contrast, similar patients with high blood pressure can slow brain atrophy by lowering their blood pressure, the researchers added.
Blood pressure is measured using two readings. The top number, called systolic pressure, gauges the pressure of blood moving through arteries. The bottom number, called diastolic pressure, measures the pressure in the arteries between heartbeats. Normal blood pressure for adults is less than 120/80, according to the U.S. National Heart, Lung, and Blood Institute. http://www.nlm.nih.gov/medlineplus/news/fullstory_137670.html
