Q. Do you think we'll ever be able to prevent Alzheimer's disease?

A. I do. Not because I'm an optimist (though I am) but because of the results of research in the past 25 years.

Q. I heard regular aerobic exercise is better for the brain than strength exercises (resistance training). Is that true?

A. The study you probably heard about involved rats, not humans. The rats were made to engage each day in sustained aerobic exercise, high-intensity interval training, or resistance training, or they were allowed to just be sedentary. At the end of the study, the researchers examined the rats' brains. The rats doing regular aerobic exercise had more brain cells than the sedentary rats. However, the rats made to perform high-intensity interval training or the ones doing resistance training did not have more brain cells than the sedentary rats.

Don't be surprised if your doctor screens you for depression at your next visit. An update to the U.S. Preventive Services Task Force recommendations for screenings, published Jan. 26, 2016, in The Journal of the American Medical Association, suggests that all adults 18 or older, including older adults, should be screened for depression when there are systems in place to ensure accurate diagnosis, effective treatment, and appropriate follow-up. The previous recommendations encouraged selective screening based on professional judgment and patient preferences. The new recommendation also includes pregnant and postpartum women for the first time. "Older adults often struggle with chronic disease, or the loss of a loved one, which may lead to depression," says Dr. Michael Craig Miller, an assistant professor of psychiatry at Harvard Medical School. "Screening is just a way to open the door for people who might otherwise not get the help they need." Dr. Miller says screening can simply be asking if, over a two-week period, you have either had little interest or pleasure in doing things or felt depressed and hopeless.

Caring for an elderly family member with disability, dementia, or both is a tough job. And those with the heaviest responsibilities suffer the most consequences, finds a study published Feb. 15, 2016, in JAMA Internal Medicine.

Researchers looked at information from two large national surveys of older adults and their family caregivers. They noted that about 15 million family caregivers are assisting almost eight million adults 65 or older, and 44% of caregivers are providing substantial care—about 28 hours per week—by helping with medication management, doctor visits, and transportation. Researchers found that people providing substantial care are more likely to live with the person they care for and are more likely to experience significant emotional, physical, and financial difficulty compared with caregivers who don't provide substantial help. Researchers also said people providing substantial care are more than five times as likely to miss out on activities they value and three times as likely to be less productive at work, compared with those who don't have such a heavy caregiving load.

A negative attitude about aging appears to be associated with a higher likelihood of Alzheimer's disease.

A study in the journal Psychology and Aging examined healthy, dementia-free subjects from the Baltimore Longitudinal Study of Aging, the nation's longest-running scientific study of aging.

As you've gotten older, have you noticed that you often find yourself marching around the house in a huff, searching for misplaced car keys or eyeglasses, or you just cannot remember the name of that new neighbor you met when walking the dog? It's frustrating, to be sure, but not inevitable — and there are things you can do to help keep your memory sharp.

"Most people get a little more forgetful with aging, but there are some simple things you can do to prevent memory slips and help your brain to learn and remember better," says Dr. Anne Fabiny, chief of geriatrics at Cambridge Health Alliance and an assistant professor of medicine at Harvard Medical School.

Ask the doctors

Q: I went for my usual check-up, and in addition to taking my blood pressure, the medical assistant handed me a form to fill out with nine questions related to my mental health. I've never had this happen before. Is this new?

A: Yes, it is new for most people. The U.S. Preventive Services Task Force (USPSTF) has just released an important depression screening recommendation. The USPSTF recommends regular depression screening for all adults, which is a modification from advice originally given in 2009, in which screening was recommended only for clinics or doctors who had adequate support systems to provide mental health care for those who were identified with depression. Since that time, multiple studies have found that mental health care from primary care clinicians works very well, and probably just as well as specialist care from psychiatrists. That isn't to say we don't need care from psychiatrists, but rather that not everyone needs a psychiatrist, especially those with mild to moderate depression.

Learning to deal with stress can lower your risk for anxiety, depression, and cardiovascular disease.

The more we learn about women's hearts, the more we realize that they are different from men's. One of the most dramatic differences is a rare heart condition called takotsubo cardiomyopathy, or broken-heart syndrome, that is nine times more common in women than in men. It has been cited as evidence that sudden emotional stress can actually cause death in some women.

Like a heart attack, takotsubo cardiomyopathy strikes suddenly with symptoms such as chest pain and shortness of breath; however, it does not involve clogged arteries. Takotsubo cardiomyopathy is brought on by a surge of stress hormones that literally bend the heart out of shape. As a result, when the main pumping chamber of the heart (the left ventricle) contracts, it balloons out, so it can't eject blood into the arteries effectively.

Music therapy can calm anxiety, ease pain, and provide a pleasant diversion during chemotherapy or a hospital stay.

It's almost impossible to find someone who doesn't feel a strong connection to music. Even if you can't carry a tune or play an instrument, you can probably reel off a list of songs that evoke happy memories and raise your spirits. Surgeons have long played their favorite music to relieve stress in the operating room, and extending music to patients has been linked to improved surgical outcomes. In the past few decades, music therapy has played an increasing role in all facets of healing.

What is music therapy?

Music therapy is a burgeoning field. People who become certified music therapists are usually accomplished musicians who have deep knowledge of how music can evoke emotional responses to relax or stimulate people or help them heal. They combine this knowledge with their familiarity with a wide variety of musical styles to find the specific kind that can get you through a challenging physical rehab session or guide you into meditation. And they can find that music in your favorite genre, be it electropop or grand opera.

Although poor health can lead to unhappiness and a shorter life, unhappiness alone is not associated with a shorter life span, according to a recent report from the Million Woman Study. That investigation has followed hundreds of thousands of women throughout the United Kingdom beginning in 1996 and has tracked deaths among the participants.

In the third year of the study, the women were asked to rate their health, happiness, stress, feelings of control, and whether they felt relaxed. When the researchers looked at data from 720,000 women with a median age of 59, they found that 83% reported being generally happy and 17% said they were unhappy. During 10 years of follow-up, 4% of participants died. When the researchers factored out poor health, which was strongly associated with unhappiness, they found that the risk of dying was essentially the same for happy and unhappy women. The study was published online Dec. 6, 2015, by The Lancet.
