Performing resistance exercises could help ease symptoms of depression.

Pumping iron might inflate not only your muscles, but also your mood, says a study in published in the June issue of JAMA Psychiatry.

The study's authors came to this conclusion after examining the results of 33 randomized clinical trials involving more than 1,800 people. They found that people with mild to moderate depression who performed resistance training two or more days a week saw "significant" reductions in their symptoms, compared with people who did not. The findings also suggested that resistance exercises may be even more beneficial for those with more severe depressive symptoms.

People who feel younger than their actual age also may have brains that age more slowly, suggests a small study published online June 7, 2018, by Frontiers in Aging Neuroscience.

Scientists took brain scans of 68 healthy older adults, ages 59 to 84, to measure the volume of gray matter in various regions. The participants then answered surveys to determine if they felt older or younger than their age and to measure their cognitive abilities and perceptions of overall health.

While it may be tempting to put a baby in a moving walker, the devices have led to thousands of injuries over the past three decades, plus they do not help babies learn to walk but in fact hinder that process.

When depression strikes, doctors usually probe what's going on in the mind and brain first. But it's also important to check what's going on in the body, since certain medical problems are linked to mood disturbances. In fact, medical illnesses — and medication side effects — may be behind nearly 10% to 15% of all cases of depression.

It's not uncommon for a physical illness to trigger depression. Up to half of heart attack survivors and those with cancer report feeling blue, and many are diagnosed with depression. Many people who have diabetes, Parkinson's, or other chronic conditions become depressed.

The adjustment from summer vacation back to the structure and demands of the school year affects many students, but some experience so much anxiety that they avoid going to school. Understanding the reasons for school refusal can help parents identify problems and act quickly.

Because social connections are vital to human development and health, and writing is a way to form or strengthen a sense of connection to others, the creative expression of writing has been found to improve health and boost healthy emotions.

The number of pregnant women who use marijuana has risen in recent years, but the effects of THC on a child’s developing brain make it much safer for women to avoid marijuana use entirely during pregnancy and while nursing.

Are you taking a medication that has depression or suicidal thinking as a potential side effect? One or both risks have been linked to use of more than 200 prescription and over-the-counter pills, including medicines that treat high blood pressure, heartburn, pain, and headaches. The more of these drugs you use, the higher the likelihood that you'll experience depression, suggests a study published June 12, 2018, in The Journal of the American Medical Association. Working with five surveys conducted over a nine-year period, researchers evaluated health information from 26,192 adults. About 37% of them reported taking such medications. Of individuals taking three or more of the medications with depression as a possible side effect, about 15% reported depression, compared with about 5% in people not using those medications. Even for people already taking an antidepressant, the addition of one or more of the identified medicines was linked to higher rates of depression. This study was based on surveys, so it didn't prove that the medications caused the reported depression. Nonetheless, if you think you're depressed (and have symptoms such as apathy, hopelessness, changes in sleep or eating habits, and persistent fatigue), ask your doctor if any of the medicines you are taking may be responsible.

Depression and heart disease often overlap. As many as one in five people with heart disease has depression. This common mood disorder is also linked to a higher risk of dying of heart disease.

Now, new research lends further support for the protective role of exercise for both conditions. The study, published online June 27 by JAMA Psychiatry, included nearly 18,000 people (mostly male) and used records dating back to the early 1970s. Researchers found that people who were fit during middle age were 16% less likely to develop depression after age 65.
