If you have persistent trouble detecting or identifying odors, that may be an early sign of dementia, according to a study in the Sept. 25, 2017, Journal of the American Geriatrics Society. Almost 3,000 older adults, ages 57 to 85, who did not have dementia were asked to detect and identify five common odors like peppermint, fish, orange, rose, and leather. Five years later, the researchers found that almost half of those who performed poorly on the smell test (were either unable to detect the odors or unable to identify what the smells were) had been diagnosed with dementia. In comparison, 79% of those who scored high on the smell test did not have dementia.

The results only show an association between poor sense of smell and dementia, but the researchers noted that a smell test could be a simple way to identify high-risk people. It isn't clear how sense of smell and dementia may be linked, but the researchers speculated that underlying causes of dementia, like amyloid plaque buildup and tau tangles in the brain, also may affect the olfactory (sense of smell) system.

If exercise were available as a pill, experts say, everyone would be taking it. One reason is that exercise is very good at defusing stress. If you exercise — especially right when the stress response is triggered — you burn off stress hormones just as nature intended, instead of letting them pile up.

What's more, just about any form of motion on a regular basis helps relieve pent-up tension. Rhythmic, repetitive movements, such as walking, running, swimming, bicycling, and rowing — and specific types of exercise such as yoga, tai chi, and qigong — actually elicit the relaxation response, too. Regularly engaging in these kinds of activities can help you ward off everyday stress.

While the holiday season is a time of festivities and reconnecting with family, for people in recovery from substance use disorders, these specific situations and events can be especially stressful. For them it’s crucial to plan ahead and to make sure recovery remains the priority at all times.

Get through the season on your own by changing your perspective, creating new traditions, and reaching out to others.

The holidays are traditionally a time for family and friends. But plenty of people find themselves alone at this time of the year, especially older adults who live by themselves, are unable to drive, or live far from grown children. "I think it's probably hardest for people who have recently lost a loved one," says Dr. Suzanne Salamon, associate chief of gerontology at Harvard-affiliated Beth Israel Deaconess Medical Center.

Emotional impact

A number of emotions may creep in when you face holidays alone. One is pressure to make the holiday an event. "There's a feeling that it's supposed to be a celebration. That may be stressful if you have no one to celebrate with," says Dr. Elyse Park, director of behavioral health research at the Harvard-affiliated Benson-Henry Institute for Mind Body Medicine.

MCI can be tough to identify, but there may be ways to postpone, and possibly prevent, its impact on memory and thinking.

Everyone has the occasional bout of forgetfulness, whether it's misplacing your keys or blanking out on a name. But if these episodes become frequent or interfere with daily life, you may have mild cognitive impairment, or MCI.

MCI falls somewhere between the usual cognitive decline of normal aging and the more serious signs of dementia and Alzheimer's disease. An estimated 10% to 20% of adults older than 65 have MCI, according to the Alzheimer's Association. But this gray area of brain health is often difficult to detect.

Try these strategies to help you fill your social calendar.

In an effort to ward off the loneliness that followed his wife's death, a 94-year-old man in Minnesota decided to install a swimming pool in his back yard for the neighborhood children. His back yard is now a hub of activity in the summer, filled with laughter, splashing children, and their parents and grandparents. And he's no longer alone.

While not everyone would be willing to go to such extreme lengths to make social connections, contact with other people should still be a top priority. Chronic loneliness does more than just make you bored; it can actually harm your health.

The changes in understanding around substance use disorders are making treatment more readily available to those who need it and reducing the stigma attached to addiction, but may make those with addiction in their family history feel that the change has come too late for them.

Ask the doctor

Q. Is there a way to avoid feeling sleepy after a holiday meal?

A. That's an unusual question: my patients usually ask me about foods to help them sleep. But with the holidays coming, the concern often is reversed. You may be with friends and family that you see only infrequently, and you don't want to nod off during the conversation.
