“With an estimated one out of three people in the United States having slightly elevated blood pressure levels, which is known as prehypertension, further studies are needed to look at whether reducing blood pressure in this group can help lower the risk of stroke,” said study author Bruce Ovbiagele, MD, MSc, of the University of California, San Diego, and a Fellow of the American Academy of Neurology.
Prehypertension is defined by a systolic blood pressure (top number) of between 120 and 139 mmHg or diastolic blood pressure (bottom number) between 80 and 89 mmHg.
For the review, researchers analyzed the results of 12 previous studies involving the blood pressure and stroke occurrence of 518,520 adults. Studies were included by searching medical databases and libraries.
The review found people with prehypertension were 50 percent more likely to develop stroke compared to people with normal blood pressure levels, even after accounting for factors such as age, sex, diabetes, obesity, cholesterol and smoking.
In addition, young and middle age people may be at risk for stroke. The review found people under age 65 with prehypertension were nearly 80 percent more likely to develop a stroke compared to people with normal blood pressure. “These people may immediately benefit from blood pressure lowering methods, such as reducing their salt intake and weight, to help reduce their risk of stroke,” Ovbiagele said.
The American Academy of Neurology, an association of more than 24,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Drone vs. truck deliveries: Which create less carbon pollution?

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
