Research we're watching

A new study from researchers at the National Institutes of Health indicates that the rate of drinking in general, and binge drinking in particular, is rising faster among women ages 60 or older than among their male contemporaries. When the researchers analyzed data from National Health Interview Surveys from 1997 through 2014, they found that the proportion of older women drinkers increased at a rate of 1.6% a year, compared with 0.7% for older men. Binge drinking — defined as imbibing four or more drinks within two hours — increased by 3.7% annually among older women, but held steady among older men. The results were reported online March 24, 2017, by Alcoholism: Clinical and Experimental Research.

The researchers speculated that baby boomers, who tended to drink more than earlier generations did in youth, have continued their habits as they've aged. Whatever the reason, the trend doesn't bode well for older women's health. Because of biological differences, at any level of alcohol consumption, women have a higher blood alcohol concentration than men, putting them at greater risk of cognitive impairment and falls. It's a good idea to limit alcohol consumption to seven drinks a week, with no more than three drinks at a sitting.

There is growing evidence that the placebo effect is at work in most successful medical therapies.

When you were a child, your mother or grandmother might have used a home remedy that made you feel better, especially when it was delivered with a soothing hand on the forehead or a kiss on the cheek. Perhaps she assured you that a cup of warm milk would help you fall asleep, and you found that it did.

Unbeknownst to you — or her — she was probably harnessing the placebo effect, loosely defined as a favorable response to a medical intervention that doesn't have a direct physiological effect. Although you may have learned later in life that there isn't much scientific evidence to support the practice, you may still sleep better after a cup of warm milk at bedtime.

Research suggests that moving out of your comfort zone is the key to staying mentally and physically young.

Finding role models who are older than we are gets more difficult as we age. But in the last few years, medical science has identified a new group we can aspire to join — the super-agers. The term refers to people in their 70s and 80s who have the mental or physical capability of their decades-younger counterparts.

What makes a cognitive super-ager?

Dr. Bradford Dickerson, a neurologist at Harvard-affiliated Massachusetts General Hospital and his colleagues have been studying super-agers for several years. Their results suggest that embracing new mental challenges may be the key to preserving both brain tissue and brain function.

Don't assume age is to blame for changes in memory, attention, and decision making.

Depression has a way of sucking the joy and meaning from life. Chronic feelings of hopelessness, apathy, or despair are part of the condition. It may also bring physical symptoms, such as weight loss, sleep disturbance, fatigue, and aches and pains. But depression can be sneaky, causing subtle changes in thinking skills that you may not attribute to the condition. "Very often, one of the first signs of depression in people ages 70 or older is a change in thinking," says Dr. Helen Farrell, a psychiatrist with Harvard-affiliated Beth Israel Deaconess Medical Center.

What's the connection?

Depression may involve the interruption or reduction of chemical messengers in the brain called neurotransmitters, such as serotonin, dopamine, and norepinephrine. These chemical changes may be the cause of your depression (if the brain systems that regulate them go awry), or they may result from other depression triggers, such as the following:

Data from several surveys indicate that the percentage of women who drink has been increasing for decades. The numerous health effects associated with alcohol consumption mean that women should be especially attentive to how much they drink.

As doctors acknowledge the role that they have played in the current opioid crisis, they, along with hospitals, medical schools, and other members of the medical community have worked to address the issue on several fronts, including instituting prescribing guidelines and offering continuing education to prescribers.
