Anticholinergic medications used to treat bladder conditions, Parkinson's disease, and depression are associated with an increased risk of dementia, according to a large study published online April 25, 2018, by The BMJ. Anticholinergic drugs help to contract and relax muscles. They work by blocking acetylcholine, a substance that also transmits messages in the nervous system. In the study, researchers compared the medical records of 40,770 people older than 65 who were diagnosed with dementia and 283,933 seniors without.

They found that people diagnosed with dementia were up to 30% more likely to have been prescribed anticholinergic medications for Parkinson's, bladder problems, or depression. Frequently prescribed anticholinergic drugs include procyclidine (Kemadrin) for Parkinson's; tolterodine, oxybutynin, and solifenacin (Vesicare) for urological conditions like overactive bladder or incontinence; and amitriptyline, dosulepin, and paroxetine for depression. However, there was no association between dementia and anticholinergic drugs used to treat other common conditions like hay fever, travel sickness, and stomach cramps.

Aerobic exercise has been linked with reducing symptoms of depression, but resistance training, such as weight lifting and bodyweight exercises like push-ups, can have the same effect.

A meta-analysis published in the June 2018 JAMA Psychiatry examined the effects of resistance training on depression symptoms in 33 clinical trials involving 1,877 people. The researchers found that people who did this type of exercise reported a significant reduction in such symptoms as low mood, loss of interest in activities, and feelings of worthlessness, compared with those who did not exercise.

Research we're watching

If you're able to quickly shrug off stressful events, that may be good for your health. A study in the March 19 issue of Psychological Science found that people who held on to stress—those who reported still having negative feelings about a stressful event the day after it happened — had more chronic health problems a decade later.

Researchers analyzed data from a nationwide survey that asked more than 1,100 adults about the number and type of stressful experiences they had each day for eight days. These included everything from arguments with others to problems at work, home, or school. Participants rated their emotional reactions to these stressors at the time and afterward.

Mindfulness is the practice of purposely focusing your attention on the present moment, such as how the air smells and feels as you walk your dog, or how a bite of bread tastes with dinner. The ultimate goal is to help shift your thoughts away from your usual preoccupations toward an appreciation of the moment and a larger perspective on life.

Scientific examination of mindfulness shows that it can improve both physical and psychological symptoms and create positive changes in health attitudes and behaviors.

Strengths are built-in capacities for certain thoughts, feelings, and behaviors. Everyone has these capacities to one degree or another. Your particular pattern of strengths is part of what makes you unique.

When you play from your strengths, you are likely to feel more energetic and perform better than when you are trying to use a capacity that comes less naturally. For example, one person trying to influence a local school board to ban soft drink sales might have the strength to speak up forcefully and clearly at a general meeting (despite the almost-universal fear of public speaking). Another person strong in team-building might feel uncomfortable speaking out in a meeting but could successfully build consensus among parents, nutritionists, and others to weigh the issue and come to a decision.

Mind-body medicine is providing new models for wellness and therapy by combining conventional and complementary approaches to treatment. At this seminar, a panel of Harvard Medical School faculty will discuss this quickly developing approach that may help shape the future of medicine.

Each spring, Harvard Medical School's Office of Communications and External Relations organizes a series of four free "mini-med school" classes for the general public in the heart of Boston's Longwood Medical Area. At the end of the seminar series, participants who attend three out of the four sessions receive a certificate of completion. Topics are selected for their appeal to a lay audience and have included the human genome, nutrition, sleep dynamics and health care access. Faculty from Harvard Medical School and its affiliate hospitals volunteer their time to present these lectures to the community.

These strategies may offer greater protection.

While there's no cure for Alzheimer's disease, ongoing research has suggested there may be ways to lower your risk.

"Much of the existing science supports how certain behavioral changes made in middle age can protect people as they grow older," says Dr. Kirk Daffner, director for the Center for Brain/Mind Medicine at Harvard-affiliated Brigham and Women's Hospital. "However, there is evidence that adopting certain healthy lifestyle habits can benefit older adults too."

The practice of yoga incorporates many separate breathing techniques (above and beyond the coordinated breathing you do during yoga routines) that can help relax you and release tension. And many of these techniques can be done anytime, anywhere — not just during yoga class.

If you'd like to reap the benefits of these breathing techniques, start with the abdominal breathing technique described below. Once you've mastered abdominal breathing, you can then try others based on the unique benefits that each technique offers.

As we grow older, there may be a tendency to feel less relevant to the people around us. We tend to withdraw as a result, and this isolation can lead to a greater risk of depression.

But here's an idea that will help you stay in the game as it helps your family better understand their own history. It's simple: write your life story.

So far, research has been mixed on whether brain training programs can improve or slow memory decline. Yet a new study published online Jan. 4, 2018, by the Journal of the American Geriatrics Society found that brain training may help people with mild cognitive impairment (MCI), the stage between normal brain aging and dementia.

Researchers recruited 145 adults, average age 72, who were diagnosed with MCI. They were split into three groups. Those in one group did two hours of brain training every week for two months. The training focused on improving memory by learning new strategies to better encode information. For example, they remembered errands by associating tasks with specific locations in their home, a process called method of loci. They also practiced how to better control their attention.
