We often think of depression as making someone feel “down,” but it can sometimes show up as cognitive symptoms — for example, trouble with adapting to new information or thinking through a solution to a problem. Researchers recently determined that several common depression medications are not effective at relieving cognitive symptoms. But there are several things people with depression can try to help return themselves to their usual level of cognitive functioning.

People new to yoga will eventually learn the sun salutation, a so-called "yoga flow." You can modify the sun salutation and still learn all the basic moves by using a chair and a floor mat. Learn more at Introduction to Yoga from Harvard Health Publishing.

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

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.
