Research we're watching

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.

You're talking with a friend about a movie you saw recently, but can't remember the actor's name. Last week you found yourself upstairs, but couldn't remember what you came up to look for. Your keys are always missing. You worry: are these normal memory lapses or early signs of Alzheimer's disease or another form of dementia?

"Because there has been so much attention paid lately to the aging baby boomer population, I think Alzheimer's disease is getting a lot of attention, which is leading a lot of people to believe they may have the condition," says Dr. Suzanne Salamon, associate chief of the gerontology division at Beth Israel Deaconess Medical Center and assistant professor of medicine at Harvard Medical School.

One of the biggest challenges a parent faces is raising a child who is consistently well behaved. Children have varying temperaments, but these suggestions can help guide parents in their efforts.

The Parkland shooting is a painful reminder that too many lives, including those of children, are taken by gun violence and firearm injuries. We all – parents, policymakers, gun owners — can take action to help prevent these tragedies. The American Academy of Pediatrics offers some specific suggestions.

Parents can help protect their children from sexual abuse by teaching children about their bodies and what is and is not appropriate behavior by adults.

Q. I keep hearing that concussions can cause problems later in life. Should I be concerned about my grandkids playing sports, particularly football?

A. Sports teach kids many important life lessons, like the value of teamwork and hard work, and the importance of tenacity and resilience. The most popular sport in the United States is football. Yet evidence has emerged that repeated head injuries (common in football) may lead to a brain disease called chronic traumatic encephalopathy (CTE). This disease, which currently can be diagnosed only at an autopsy, causes difficulty thinking, severe mood swings, anger, violence — and death.
