As we grow older, there may be a tendency to feel less relevant to the people around us. We tend to withdraw as a result, and this isolation can lead to a greater risk of depression.

But here's an idea that will help you stay in the game as it helps your family better understand their own history. It's simple: write your life story.

In the journals

So far, research has been mixed on whether brain training programs can improve or slow memory decline. Yet a new study published online Jan. 4, 2018, by the Journal of the American Geriatrics Society found that brain training may help people with mild cognitive impairment (MCI), the stage between normal brain aging and dementia.

Researchers recruited 145 adults, average age 72, who were diagnosed with MCI. They were split into three groups. Those in one group did two hours of brain training every week for two months. The training focused on improving memory by learning new strategies to better encode information. For example, they remembered errands by associating tasks with specific locations in their home, a process called method of loci. They also practiced how to better control their attention.

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 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.
