It has been known for some time that air pollution causes heart and lung diseases. Now, results from three different studies on populations in different parts of the world show an association between higher levels of air pollution and greater risk of cognitive impairment, dementia, and Alzheimer’s disease.

Do you struggle with decisions? These strategies can help you make good choices more efficiently.

We make countless choices every day. Most are the mundane variety: what to eat, what to wear, what movie to watch. But often our decisions (or lack thereof) have a significant impact on our well-being.

Poor decision making is often a consequence of natural cognitive decline. This can cloud people's judgment about what is the right course of action or make it harder to weigh multiple options. The result is that people make questionable choices, or they feel overwhelmed and don't make any decision, which is sometimes even worse.

If you haven't made a video call yet, give it a try to fight isolation.

When much of the world began lockdowns to battle coronavirus in March 2020, many people turned to video calls to fight off the loneliness that often accompanies social isolation. Tech companies reported that the use of video calls for socializing surged by as much as 80%, enabling people to "see" family and friends. But it doesn't take a lockdown to warrant the use of this technology.

The epidemic of loneliness and isolation

Loneliness affects more than a third of older Americans. Another third of older adults feel isolated: they may be living alone, lack transportation, or live far from loved ones. Or they may have outlived a spouse or friends.

Need help staying positive during trying times? Live more in the moment, but also focus on how to cope with future stresses. This advice comes from a study published online March 25, 2020, by Personality and Individual Differences.

Researchers explored two factors in how people handle stress: mindfulness and proactive coping. Mindfulness is when people live in the moment rather than dwelling on the past or worrying about the future. Proactive coping is when people make efforts to reduce the effect stress has on them.

Before taking pills for a temporary situation, consider the risks.

You might think that using an antidepressant temporarily could help you weather a challenging time, such as a period of grief, extreme stress, or serious illness. But you shouldn't just jump into taking an antidepressant, cautions Dr. Jane Erb, psychiatric director of the Behavioral Health Integration in Primary Care Program at Harvard-affiliated Brigham and Women's Hospital.

"There's no evidence that taking an antidepressant in the short term will help or that it will prevent longer-term consequences of stress, such as post-traumatic stress disorder," she says.

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.

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.

Everyone has the occasional "senior moment." Maybe you've gone into the kitchen and can't remember why, or can't recall a familiar name during a conversation. Memory lapses can occur at any age, but aging alone is generally not a cause of cognitive decline. When significant memory loss occurs among older people, it is generally not due to aging but to organic disorders, brain injury, or neurological illness.

Studies have shown that you can help prevent cognitive decline and reduce the risk of dementia with some basic good health habits:

As more older people undergo surgeries, the risk of complications increases, including for cognitive decline following their procedures, particularly after cardiac surgery. But awareness and pre-planning with your care team can help you avoid such complications.
