Drinking too much alcohol could raise the risk of developing early-onset dementia, says a study published online Feb. 20, 2018, by The Lancet Public Health.

The way you live, what you eat and drink, and how you treat your body can affect your memory just as much as your physical health and well-being. Here are five things you can do every day to keep both your mind and body sharp.

1. Manage your stress. The constant drumbeat of daily stresses such as deadline pressures or petty arguments can certainly distract you and affect your ability to focus and recall. But the bigger problem is an ongoing sense of anxiety — that can lead to memory impairment. If you don't have a strategy in place for managing your stress, protecting your memory is one reason to get one. Deep breathing, meditation, yoga, and a "mindful" approach to living can all help.

Many people have taken a friend’s or family member’s pain medication on occasion, but the ongoing opioid crisis has drawn attention to such behavior, forcing doctors, hospice workers, and other care providers to tighten their procedures and track quantities and dosages of pills more carefully.

The health risks of loneliness and isolation have been known for some time, but more recently research has shown the specific effects in the brain. Finding ways to make connections with other people is the best "medicine" to alleviate the mental and physical effects of loneliness.

Mental stress can cause arteries throughout the body to constrict. In people with heart disease, this effect can reduce blood supply to the heart muscle, a phenomenon known as mental stress–induced ischemia. New research suggests that this problem may affect women differently from men.

For the study, 678 adults (average age 63) delivered a speech while researchers measured their blood pressure and heart rate, took imaging pictures of their hearts, and measured the constriction of tiny arteries in their fingers. In women, mental stress–induced ischemia mostly resulted from constriction of tiny arteries. The resulting greater resistance requires the heart to use more force in pumping blood. In contrast, the ischemia seen in men was mostly due to a rise in blood pressure and heart rate. The findings are yet another reminder for people to find ways to avoid and manage mental stress. But they also hint that women's hearts may be more vulnerable to this problem. The study was published online Dec. 21, 2017, by the journal Arteriosclerosis, Thrombosis, and Vascular Biology.
