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.

You can't see your blood pressure or feel it, so you may wonder why this simple reading is so important. The answer is that when blood pressure is high, your heart is working overtime to pump blood through your body. This extra work can result in a weaker heart muscle and potential organ damage down the road. Your arteries also suffer when your blood pressure is high. The relentless pounding of the blood against the arterial walls causes them to become hard and narrow, potentially setting you up for stroke, kidney failure, and cardiovascular disease.

A healthy lifestyle — not smoking, losing excess weight, eating nutritious foods, and exercising regularly — is the cornerstone for preventing and treating hypertension.

Men need to be challenged to be healthy in mind and body.

It might seem like retirement is a time to take it easy and devote yourself to gardening, golfing, and napping. But don't take it too easy, say Harvard experts. An absence of challenges can have the same effect as too much stress, compromising your physical and mental health. For optimal well-being, you need to stay engaged—with your own interests as well as with other people.

The best-quality evidence available does not prove that taking a statin can cause memory loss or other changes in mental functioning, according to a review in the Journal of General Internal Medicine. Since 2012, the FDA has required that statin manufacturers include a warning on drug packaging that statins could impair mental functioning, but this has been controversial. Researchers took a look at the published evidence for possible mental side effects of statins.

The new review covered randomized clinical trials involving nearly 47,000 people. Such trials are the gold standard in medical research. These included 23 trials in which researchers explicitly measured mental functioning, as well as trials that kept track of mental changes reported by participants.

Anticholinergics, a group of medications that includes many over-the-counter and prescription drugs, are well known for causing confusion in older adults. Common medications with anticholinergic properties include medications to treat overactive bladder, such as oxybutynin (Ditropan); medications to treat allergies and sleeping problems, such as diphenhydramine (Benadryl, Sominex, Unisom); and medications used to treat depression, such as amitriptyline (Elavil). It's generally believed that confusion that may develop from anticholinergics clears up when someone stops taking the drugs. But now it appears that the medications are associated with a more permanent effect. A study published online Jan. 26, 2015, in JAMA Internal Medicine linked daily anticholinergic use among older adults for three or more years to an increased risk for developing dementia and Alzheimer's disease.

The study didn't prove that anticholinergics cause dementia; it only found an association between people who take the medications and people who develop dementia. Nevertheless, the researchers suggest that doctors avoid prescribing anticholinergics when possible, or at least limiting the medications to the lowest doses possible. If you're taking an anticholinergic, talk to your doctor about the risks the medication poses, including the risk of falls as a result of confusion.
