Lowering blood pressure to recommended levels can prevent dementia and the memory and mental problems that often show up first, researchers reported Wednesday.
People whose peak blood pressure measurement was reduced to 1
"That's really exciting," said Heather Snyder, senior director of medical operations for the Alzheimer's Association. The results were presented at the club's annual convention in Chicago.
"These results truly confirm the saying that what is good for the heart is good for the brain," Dr. Mark Supiano, a geriatrician at the University of Utah Health System and the VA Salt Lake City health care system, who have collaborated on the study.
It may take several more years for the study to conclusively show whether the risk of Alzheimer's was actually lowered because of lower blood pressure Researchers have said:
It's the first intervention that has clearly shown that they have the rate of mental decline lowers. And it was one of two promising studies that were presented at the annual Alzheimer's Association meeting in Chicago. A second study found that an experimental drug could slow the progression of Alzheimer's disease in early-stage patients.
Alzheimer's disease is the sixth most common cause of death in the United States. More than 5 million Americans have been diagnosed with Alzheimer's, including 200,000 under age 65.
There is no cure, and although there is evidence that a healthy lifestyle can lower the risk, no controlled trial comparing people with treatment with individuals who were not given treatment could cause a decrease in cognitive decline or dementia demonstrate.
It does, Dr. Jeff Williamson of the Wake Forest School of Medicine and colleagues. At the beginning, you examined 9,361 people with an average age of 68 years. In the half, the blood pressure was lowered to 120, while the other half received a standard blood pressure therapy.
"These findings support the need to maintain a well-controlled blood pressure, especially for those over 50 years old, Williamson said in a statement.
There were fears that it might be too much."
"There were much concern that there could be cognitive damage in lowering blood pressure, "Supiano told NBC News  The fear was that less blood would enter the brain if blood pressure were lowered so much.
