Preventive Measures for Recurring Neck Pain

If you're like many people, at some point, you're likely to have a pain in the neck -- literally, that is. In fact, up to 50 percent of American adults experience neck pain each year. And if you're among those who have experienced neck pain, chances are you'll feel it again in the next one to five years. The good news is that only about 10 percent of people have neck pain so severe that it affects their ability to carry out daily activities. More...

Substance Abuse and Aging: A Growing Problem

Current guidelines suggest that one alcoholic drink a day for women and two drinks a day for men may be beneficial for health.

Liver Damage: Medication May Be the Culprit

In the United States, injury caused by medication is the most common cause of acute liver damage -- that is, damage that comes on suddenly. While efforts are made to ensure the safety of medications before they're introduced to the marketplace, the reality is that some approved drugs still may cause harm -- and liver damage (which in rare cases can lead to liver failure) is the number-one reason a particular medication is pulled from the shelves.

Update: New Cardiovascular Disease Prevention Guidelines

In November 2013, the American Heart Association and the American College of Cardiology issued new guidelines for reducing the risk of heart disease and stroke.

Sudden, Severe Headache? Take Action

Emergency room (ER) doctors treat more headaches than you might expect: It's one of the top five reasons for an ER visit, according to the Centers for Disease Control and Prevention. Most primary-type headaches like migraine, cluster and tension headaches can be treated at home with over-the-counter pain relievers or prescription drugs. But a sudden, severe headache's incapacitating pain can -- and should -- send some people to the hospital. More...

Four Common Asthma Irritants To Avoid -- And Why

Even if your asthma is well controlled with medication, irritants -- smoke, air pollution, strong odors and cold air -- can worsen your asthma symptoms. In addition, certain allergens, such as pollen, dust mites, animal dander and mold, may also cause airway inflammation and may trigger an asthma attack. Although it's not possible to completely eliminate irritants and allergens from the environment, you can take steps to minimize your exposure to them. Here's a look at four common asthma irritants.

Memory Loss: It’s Not Inevitable

The brain contains about 100 billion neurons. A common misconception is that tens of thousands of neurons die each day. In reality, few neurons die over a person's lifetime, but they do shrink. This shrinkage may partially explain why mental functioning slows in middle and older age. (Serious memory problems do occur when major disorders such as a stroke or Alzheimer's destroy whole clusters of neurons.) More...

From Research: CT Scans and Osteoporosis

Bone mineral density (BMD) testing is recommended for women 65 and over and men 70 and over. Yet in the United States only a fraction of both groups have had a dual-energy X-ray absorptiometry (DXA) test. In contrast, some 80 million computed tomography (CT) scans are performed yearly as part of the diagnostic workup for gastrointestinal symptoms, suspected cancer and other conditions, leading researchers to speculate whether these tests might incidentally detect osteoporosis.

Do You Really Need a Biopsy? Two New Tests Help You Decide

It's the holy grail -- a prostate cancer test that can, with complete accuracy, distinguish men who have prostate cancer from those who are cancer free and, when prostate cancer is diagnosed, determine whether it's an aggressive form that requires prompt treatment or a slow-growing tumor that may only need close monitoring.
