Study links high blood pressure to memory trouble (USA)

"People as young as 45 with high blood pressure are more likely to have memory troubles, U.S. researchers said on Tuesday in a study suggesting aggressive early treatment of the condition may pay huge dividends. They said people with high diastolic blood pressure - high readings on the bottom number of the blood pressure reading - were more likely than those with normal readings to have problems with memory and thinking called cognitive impairment. The study, published in the journal Neurology, is the largest to look at the link between high blood pressure and memory problems. "It's possible that by preventing or treating high blood pressure, we could potentially prevent cognitive impairment, which can be a precursor to dementia," Dr. Georgios Tsivgoulis of the University of Alabama at Birmingham, who led the study, said in a statement. Researchers studied nearly 20,000 people 45 and older who had never had a stroke or mini-stroke - a common cause of memory problems. More than 7 percent had memory problems, and nearly half were taking medication for high blood pressure. High blood pressure is defined as a reading of 140/90 or above
