An analysis of multiple studies looking at the relationship between high blood pressure and cognitive health –– abilities like thinking, memory, and attention –– found that older people who lower high blood pressure are slightly less likely to develop cognitive impairment or dementia.

The brain’s neuroplasticity — its ability to adapt and change — makes it possible for us to learn new skills and solve complex problems, but it also makes some people more vulnerable to the consequences of substance use disorders. This same ability also makes it possible for a person to make cognitive modifications in order to change an addictive behavior.

The singular focus of health care services on COVID-19 has disrupted mental health care, and people with new or existing issues are having difficulty accessing much-needed care. A global initiative launched at Harvard Medical School aims to rectify this situation and transform global mental health.

Traumatic events, whether global or in a person’s own life, can take a toll on mental health. How can you reduce your stress and regain your emotional composure after going through a difficult time?

Reduce your stress levels and maintain a sense of normalcy during and after traumatic events.

For most Americans, 2020 has already been a rough year — and it's not even half over. A pandemic, natural disasters, economic decline, and, for many, the loss of a job have taken a toll on their mental health.

"Stress is particularly acute when you're experiencing a situation that is outside of your control," says Dr. Kerry Ressler, professor of psychiatry at Harvard Medical School. "You may feel stuck, frozen, or helpless." After a traumatic period, even when things settle down, it can be difficult to move on and regain a sense of normalcy.

These popular pets have been linked to a range of heart-related benefits.

Seeing a dog's wagging tail and furry face can be heartwarming. But living with and caring for a dog may be heart-protecting — and might even help you live longer, according to a growing body of research.

The latest findings include two articles published last year in Circulation: Cardiovascular Quality and Outcomes. One pooled findings from 10 studies involving a total of 3.8 million people who were followed between one and 22 years. Dog owners were 31% less likely to die from a heart attack, stroke, or other cardiovascular condition than people who didn't own dogs. A separate study, which followed more than 335,000 heart attack and stroke survivors over 12 years, found that having a dog was linked to a 21% lower risk of death from any cause.

Many women making the transition to menopause have trouble sleeping. Several strategies can help you get the rest you need.

If you're a woman of a certain age and you often find yourself staring at the ceiling in the middle of the night, you're not alone. The years leading up to menopause and the period that immediately follows are the times that women are most likely to report problems sleeping, according to the National Sleep Foundation. Many different conditions that are common in this stage of life — including hot flashes, obstructive sleep apnea, and mood disorders such as depression or anxiety — can cause sleep problems.

Lack of sleep is more than just a nuisance. "We now understand that high-quality sleep is absolutely vital to good health," says Dr. JoAnn E. Manson, the Michael and Lee Bell Professor of Women's Health at Harvard Medical School. This means that seeking care should be a priority if you are experiencing problems.
