(CNN)Resveratrol, a compound produced in the skin of grapes to defend against insects and bacteria, is present in red wine. Mice that were fed large quantities of this compound experienced a beneficial drop in blood pressure, according to a study published Thursday in the journal Circulation. Resveratrol may someday be used to develop a new class of high blood pressure drugs for humans, believe the researchers, who explored the mechanics of how it works. However, because they did not experiment on human patients, it has not been proven that these "animal findings can be translated to humans," wrote the study authors, from King's College London. For Alzheimer's patients, resveratrol brings new hope This is not your cue to start drinking copious amounts of red wine, they added. Globally, about 40% of adults 25 and older have high blood pressure, while in the United States the same is true of 1 in 3 adults, according to the US Centers for Disease Control and Prevention.

Source: (c) pressmaster/fotosearch As a psychologist who trains therapists around the country in new ways to combat anxiety, I have become interested in the relationship between anxiety and high blood pressure. Which causes which? And can treatments for one help with the other? Here’s the latest that I've found in my search for answers. Does anxiety cause high blood pressure? The answer seems to be complex: No and yes. Sheldon Sheps, M.D., writes for the Mayo Clinic that, “Anxiety doesn't cause long-term high blood pressure (hypertension). But episodes of anxiety can cause dramatic, temporary spikes in your blood pressure. If those temporary spikes occur frequently, such as every day, they can cause damage to your blood vessels, heart, and kidneys, as can chronic high blood pressure." So even though anxiety may not cause chronic high blood pressure, it can cause similar health problems. Dr. Sheps adds a warning about … [Read more...] about Why Do Anxiety and High Blood Pressure Go Hand-In-Hand?
WASHINGTON — High blood pressure, particularly in the arteries that supply blood to the head and neck, may be linked with declining cognitive abilities, according to a new study from Australia.Researchers found that people with high blood pressure in the central arteries — including the aorta, the largest artery in the human body, and the carotid arteries in the neck — performed worse on tests of visual processing, and had slower thinking and poorer recognition abilities.Typically, blood pressure measurements are taken from the brachial artery in the arm, but looking at the health of the central arteries may be a more sensitive way to assess cognitive abilities, said study researcher Matthew Pase, of the Center for Human Psychopharmacology at Swinburne University in Melbourne. The central arteries directly control bloodflow to the brain."If we can estimate the blood pressure in central arteries, we might be able to better predict cognitive function and cognitive … [Read more...] about High Blood Pressure Linked to Declining Brain Function
High blood pressure might actually be a good thing, when the condition occurs in older people who are especially frail.Researchers found that among people older than 65 who were unable to walk 20 feet, those with high blood pressure were 62 percent less likely to die over a five-year period, compared with those who had normal blood pressure.However, for people of the same age who weren't frail, those with high blood pressure were 35 percent more likely to die than those with normal blood pressure.The research "demonstrates that older adults are a heterogeneous group," and that they ought to be treated as such by health care providers, said study researcher Michelle Odden, an epidemiology professor at Oregon State University. “We need to look at the older, frail population to see if they’re different."A short walkIn the study, the researchers used data gathered from 2,340 people over age 65 during the National Health and Nutrition Examination Surveys, conducted by the … [Read more...] about Why High Blood Pressure Could Be Good for Some Older People
Humans like to think there's safety in numbers; if people are all dealing with the same problems, those problems often aren't as scary, right? Well when it comes to health, this kind of mentality doesn't work. Just because one in three people has high blood pressure (according to the Centers for Disease Control and Prevention) doesn’t mean it's okay.High blood pressure, or hypertension, increases the risk of heart disease and stroke, two leading causes of death in the United States.Blood pressure is a measure of the force of blood against artery walls. It’s normal for this number to fluctuate throughout the day, but it can lead to serious health problems if it remains elevated for long stretches of time.Blood pressure is measured using two numbers: systolic and diastolic. Systolic is the pressure in blood vessels when the heart is beating. Diastolic represents the pressure when you’re the heart is at rest.You’re at risk for high blood pressure if you are obese, … [Read more...] about Easy Ways to Lower Blood Pressure
