People with anxiety or depression often have trouble making sound decisions. But a study suggests their judgment can improve if they focus on past successes instead of mistakes. The findings were published online Dec. 22, 2020, by the journal eLife.

Researchers recruited 86 adults, divided into three groups. In one group were people diagnosed with generalized anxiety disorder or major depression. Another group consisted of people who showed anxiety or depression symptoms, like excessive worrying and not feeling good about the future, but were not clinically diagnosed. The final group included those without anxiety or depression.

Many cases of memory loss aren't related to dementia, but stem from other, treatable conditions.

You've been forgetting things lately — your keys, or maybe names. Sometimes you struggle to find the right word in conversations or repeat yourself to others. You may worry: are these signs of dementia?

If this sounds like you, you're not alone. Many people find their way into Dr. Tammy Hshieh's office wondering the same thing. But most of the time, it's not dementia causing their problems, says Dr. Hshieh, a geriatrician at Harvard-affiliated Brigham and Women's Hospital and Dana-Farber Cancer Institute and assistant professor of medicine at Harvard Medical School.

Q. I've read that getting the flu shot annually will weaken my immune system over time. Is this true?

A. A study published in the March 1, 2017, issue of The Journal of Infectious Diseases investigated whether getting an annual vaccination against influenza (flu) can weaken your body's natural ability to protect itself from the disease. Past studies have raised similar concerns. Researchers at the University of Bergen in Norway followed 250 health care workers. Some of them got a flu vaccination every year from 2009 through 2013. The others only received the vaccine once in 2009 and not in the years from 2010 to 2013. The researchers then took blood samples before the influenza season (and before people were vaccinated that season), from the members of both groups and looked at different markers to gauge how well their immune systems would respond to the influenza virus. They found that getting an annual flu vaccination did not weaken the immune system. As a group, the people who got the flu shot annually appeared to have a better immune response to influenza than those vaccinated only once.

Looking for a simple way to help reduce stress, anxiety, and depression, and maybe even improve your memory? Take a walk in the woods.

"Many men are at higher risk for mood disorders as they age, from dealing with sudden life changes like health issues, the loss of loved ones, and even the new world of retirement," says Dr. Jason Strauss, director of geriatric psychiatry at Harvard-affiliated Cambridge Health Alliance. "They may not want to turn to medication or therapy for help, and for many, interacting with nature is one of the best self-improvement tools they can use."
