You probably know there are many ways to improve your well-being and chances of living longer, such as exercising more or eating better. But did you know that maintaining meaningful relationships also may play an important role in health, happiness, and longevity? "Good, close relationships appear to buffer us from the problems of getting old," says Dr. Robert Waldinger, a psychiatrist with Harvard-affiliated Massachusetts General Hospital.

Eight decades of research

Dr. Waldinger is the current director of the Harvard Study of Adult Development, an ongoing analysis that's followed more than 700 men since they were teenagers in 1938. More than 60 of the original participants, now in their 90s, are still taking part.

By the time memory loss shows up, the disease is well under way. Researchers are finding ways that may reveal brain changes sooner.

For a long time, memory loss was seen as the telltale sign of Alzheimer's disease. While this is certainly the most common symptom, it may not be the best way to identify the disease in its early stages.

"A major problem of Alzheimer's diagnosis, and ultimately effective treatment, is that by the time the first clinical symptoms appear, irreversible damage to the brain has already occurred," says Dr. Seth Gale, a neurologist with Harvard-affiliated Brigham and Women's Hospital. "It is now believed that Alzheimer's-related changes begin in the brain at least a decade before any symptoms emerge."

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:

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.

Studies suggest that adopting a sunnier outlook may improve your health and even extend your life.

In these turbulent times, it's sometimes a struggle to maintain a glass-half-full view of life. But if you can, it may serve you well. A growing body of research links optimism—a sense that all will be well—to a lower risk for mental or physical health issues and to better odds of a longer life.

One of the largest such studies was led by researchers Dr. Kaitlin Hagan and Dr. Eric Kim at Harvard's T.H. Chan School of Public Health. Their team analyzed data from 70,000 women in the Nurses' Health Study who, in 2004, had answered questions about how they viewed their futures
