Researchers from the biotechnology company Biogen have reported that a new drug reduced the amount of amyloid plaques—the brain deposits associated with dementia—and slowed cognitive decline in people with early Alzheimer's disease. They presented the report March 20, 2015, at the International Conference on Alzheimer's and Parkinson's Diseases in Nice, France.

The researchers studied 166 people ages 50 to 90 who had been diagnosed with mild Alzheimer's. The participants were randomly assigned to receive either a placebo or one of four different doses of the drug aducanumab—an antibody that attaches to amyloid deposits and turns the immune system on them.

Harvard researchers Joshua Hartshorne and Laura Germine have added to the growing body of research indicating that, in some respects, our cognitive function is improving, not declining, as we age. Their report, published online March 15, 2015, by Psychological Science, indicates that our vocabulary skills keep improving past retirement age.

The researchers wanted to understand how and when reasoning and memory change over the life span as a basis for distinguishing normal from abnormal aging. They recruited 48,000 volunteers of all ages and had them complete online tests that measured brain processing speed, memory, emotional intelligence, and vocabulary.

Music has charms to soothe a savage breast, as the 17th-century poet William Congreve wrote. In fact, music might soothe your heart by relaxing your arteries, a small study hints.

Researchers measured arterial stiffness in 20 healthy young adults before and after they listened to 30 minutes of classical music, rock music, or nothing (as a control). They used a technique called carotid-femoral pulse wave velocity (PWV). This measures the time it takes for the pulse to travel to the carotid artery in the neck versus the femoral artery in the leg. Longer pulse times suggest stiffer arteries, which translates to a higher risk of cardiovascular problems. Higher "wave reflections" (another measure of artery health) are also linked to heart disease risk.

Stay well when caring for a loved one by maintaining your physical and emotional health. Caring for yourself means you'll be able to care for another.

Pets can provide their owners with more than companionship. A new study, published online in the journal PLoS One, shows that pets can also help create human-to-human friendships and social support, both of which are good for long-term health. The effect isn’t limited to dogs. Other kinds of pets, including cats, rabbits, and snakes, can also be catalysts for making friends and finding social support. In a survey of residents of four cities, being a pet owner was the third most common way that respondents said they met people in their neighborhoods. Pet owners were 60% more likely than non–pet owners to get to know people in their neighborhoods they hadn’t known before. They were also more likely to have reported befriending someone they met through a pet-related connection or getting social support from them. As described in Get Healthy, Get a Dog, a Special Health Report from Harvard Medical School, pet ownership has many direct physical and mental health benefits.

Balance can't be taken for granted past a certain age; it must be maintained — both in mind and body.

General physical fitness and targeted exercises to improve balance can prevent falls. But so can staying mentally active to maintain brain health. A sharp mind helps you to think — and stay — on your feet.

Relaxation, meditation, positive thinking, and other mind-body techniques can help reduce your need for pain medication.

Drugs are very good at getting rid of pain, but they often have unpleasant, and even serious, side effects when used for a long time. If you have backache, fibromyalgia, arthritis, or other chronic pain that interferes with your daily life, you may be looking for a way to relieve discomfort that doesn't involve drugs. Some age-old techniques—including meditation and yoga—as well as newer variations may help reduce your need for pain medication.

Distracting background music could make certain memory tasks more challenging for aging brains, suggests a study in The Gerontologist. The study involved one group of participants ages 18 to 30 and another ages 60 to 75. They studied images of faces paired with names on a computer screen, either in silence or while listening to instrumental music. Later they had to recall the name-face pairs while listening to music.

The music had no effect on test scores in the younger people. In contrast, the older people remembered 10% fewer names learned when listening to background music, compared with studying in silence.

The tragic story of copilot Andreas Lubitz, the man who apparently crashed Germanwings flight 9525 into the Alps in an act of suicide and murder, demonstrates the opaqueness of mental illness. It is difficult to know when a person is struggling with private psychological and emotional pain that might lead to dangerous or destructive behavior. All of us tend to keep our thoughts, especially our most disturbing ones, to ourselves. Even when encouraged to speak those thoughts aloud — to a mental health professional, for example — it is very difficult to do so. This tragedy will likely spark calls for increased scrutiny of pilots. That’s not necessarily a bad thing, but it could lead to the unintended and undesirable consequence that pilots will become even more wary of seeking help. To honor the lives lost will require policies that protect the public while not being punitive to pilots.

Is brain damage an inevitable consequence of American football, an avoidable risk of it, or neither? An editorial published yesterday in the medical journal BMJ poses those provocative questions. Chad Asplund, director of sports medicine at Georgia Regents University, and Thomas Best, professor and chair of sports medicine at Ohio State University, offer an overview of the unresolved connection between playing football and chronic traumatic encephalopathy, a type of gradually worsening brain damage caused by repeated mild brain injuries or concussions. The big question is whether playing football causes chronic traumatic encephalopathy or whether some people who play football already at higher risk for developing it. The Football Players Health Study at Harvard University hopes to provide a solid answer to that and other health issues that affect professional football players.
