Taking a class to explore a subject or learn a new skill may increase cognitive ability and slow mental aging.

Active aging involves more than moving your body. You also need to move your brain. "When you exercise, you engage your muscles to help improve overall health," says Dr. Ipsit Vahia, director of geriatric outpatient services for Harvard-affiliated McLean Hospital. "The same concept applies to the brain. You need to exercise it with new challenges to keep it healthy."

A fun way to do this is to sharpen your No. 2 pencils and go back to school. "New brain cell growth can happen even late into adulthood," says Dr. Vahia. "The process of learning and acquiring new information and experiences, like through structured classes, can stimulate that process."

Proton-pump inhibitors are among the most-prescribed medications, but is long-term use safe?

Proton-pump inhibitors (PPIs), which are used to treat a variety of gastrointestinal problems, are among the most popular drugs in the United States. In fact, the FDA estimates about one in 14 Americans has used a PPI.

Research We’re Watching

Cognitive behavioral therapy has been shown to be effective in treating chronic back pain, but it requires regular visits with a psychotherapist and can be expensive. A team from the University of Washington designed a study to determine whether mindfulness stress reduction—a technique that can be learned and practiced on one's own—is as effective in relieving pain and restoring function as cognitive behavioral therapy or conventional treatment with drugs and physical therapy.

The researchers enrolled 342 people ages 50 to 70—two-thirds of whom were women—who'd had back pain for an average of more than seven years. They randomly assigned the participants to one of three equal groups: one group was taught to practice mindfulness stress reduction, the second received cognitive behavioral therapy, and the third received conventional treatment as needed.

About one in six strokes can be traced to atrial fibrillation. Doctors now have newer and better options to lessen this risk.

Close to one in 10 people ages 65 or older have atrial fibrillation (afib), the most common heart rhythm disorder. During a bout of afib, the usually rhythmic contractions of the heart's upper chambers (the atria) are replaced by an ineffectual quiver. While the symptoms, which include a racing heartbeat, dizziness, and shortness of breath, are troublesome for some people, the real threat lies in the increased risk of stroke that accompanies the condition.

When the heart takes on the afib rhythm, blood does not completely move out of the atria. Instead, it tends to pool and clot in a pouchlike extension in the upper left quadrant of the heart, called the left atrial appendage. If these clots break loose, they may travel to the brain and cause a blockage. This is known as an ischemic stroke.

People who do volunteer work may reap benefits beyond the satisfaction of helping others.

Doing volunteer work may give you a greater sense of purpose in life—a positive emotion that’s been linked to a lower risk of heart disease.

If you volunteer on a regular basis, perhaps you've experienced the emotional rewards of donating your time. What you might not realize, however, is that volunteering may offer some added advantages for your heart.

People new to yoga will eventually learn the sun salutation, a so-called "yoga flow." You can modify the sun salutation and still learn all the basic moves by using a chair and a floor mat. Learn more at Introduction to Yoga from Harvard Health Publishing.
