Looking for a boost or alternative to antidepressant medicines? Here are four therapies that may help relieve your symptoms.

Many people suffer bouts of mild or moderate depression as they age. Health issues and the loss of a spouse, family member, or friend are common triggers that can lead to persistent sadness and loss of enjoyment.

While antidepressants like selective serotonin reuptake inhibitors (SSRIs) can be helpful to relieve and control symptoms, they are not always the right choice.

Researchers found that people who go on to develop Alzheimer's disease or a related disorder are more likely to miss paying a bill prior to being diagnosed, but such people face more significant related issues: poor financial decision-making and falling victim to financial scams.

Continuing work and satisfaction in life can help older adults preserve their cognitive health.

Declining brain health is perhaps the greatest fear of older adults. The good news is that you can take steps to maintain your thinking and memory for many years to come.

A healthy diet, regular aerobic exercise, and proper sleep are essential to keep your brain healthy. But work engagement and life satisfaction are two additional factors that confer mind benefits.

Because older adults often experience temporary changes in memory and thinking after having general anesthesia, they may worry that it increases their risk of dementia. A recent study should help put their minds at ease. Researchers found no association between the type of anesthesia and dementia risk, according to findings published online Oct. 6, 2020, by the Journal of the American Geriatrics Society.

The study looked at almost 7,500 people ages 66 or older without diagnosed dementia who underwent surgery requiring either general anesthesia (where you are unconscious) or regional anesthesia (where you are awake and the surgical area is numbed). The researchers included only people who had not had any previous surgery and stopped assessing those who had a second surgery later.

Although executive function skills begin to develop in the first year of life, the time at which children reach these milestones varies. Some children experience challenges or delays related to their executive function skills, but these skills can be improved through evidence-based interventions.

Many commonly used drugs have anticholinergic effects, meaning the drugs block the action of acetylcholine. Nerve cells release acetylcholine to transmit impulses to other nerves in the brain and throughout the body. Previous research has shown a link between these drugs and dementia. Now a study has found a similar link with mild cognitive impairment (MCI), especially if you take larger doses. The findings were published online Sept. 2, 2020, by Neurology.

Some medications are designed purposefully to block acetylcholine, such as those used for urinary incontinence. But more often the anticholinergic action is a side effect of drugs taken to treat conditions like allergies, colds, and depression.

Research we're watching

According to a study published in the Aug. 4, 2020, issue of Neurology, the number of new cases of dementia in Europe and North America has dropped 13% every 10 years over the past 30 years. Researchers looked at data collected by the Alzheimer's Research Consortium, which included people over age 65 in Europe and the United States.

The actual number of adults with dementia has increased dramatically in recent years as life expectancy increases. The condition currently affects some 47 million people worldwide, and that number is expected to increase in coming decades.

Contrary to conventional wisdom, some blood pressure drugs are linked to a lower risk of depression.

Like all medications, blood pressure drugs sometimes cause unwanted side effects. While many are mild and short-lived, some are more worrisome, including mood changes such as depression. But contrary to what doctors have long assumed, blood pressure drugs may not raise the risk of depression. In fact, some appear to be linked to a lower risk, according to a recent study (see "Depression rates in people taking different blood pressure drugs").

"The traditional view has been that blood pressure drugs that cross the blood-brain barrier are more likely to cause depression," says Dr. Randall -Zusman, a cardiologist at Harvard-affiliated Massachusetts General Hospital. Depression has also been associated with drugs known as beta blockers. But beta blockers (which work in part by slowing the heart rate) can also make you feel tired and listless, which may dampen your mood, Dr. Zusman explains.

Need a little inspiration? The next time you take a walk outside, note things that spark a sense of wonder or awe. That's what some older adults tried for a small study published online Sept. 21, 2020, by the journal Emotion. Of the 50 people who took part, half went for weekly 15-minute walks outdoors (alone) for eight weeks, and snapped "selfies" along the way. The other half took the same walks and selfies, but visited a new place each time. They were asked, especially, to note things that inspired a sense of awe — like tree colors or leaves underfoot softened by rain. Participants also answered surveys about the emotions they felt on walk and non-walk days. After analyzing responses and photos, scientists found that people who people took the "awe walks" reported less distress and increasing awe, joy, compassion, and gratitude, compared with people on the regular walks. Awe walkers also smiled more and made themselves smaller in their photos, focusing more on landscapes — a sign of a greater appreciation of the world around them. Try it yourself: On your next walk, imagine you're seeing things for the first time. What will inspire you? Perhaps a path lined with trees, the shore of a lake, or an up-close look at skyscrapers. Jot down your observations, and see if you feel a sense of wonder and joy. Happy trails!
