Researchers Identify Brain Circuits That Help People Cope with Stress
Research supported by the National Institutes of Health (NIH) has identified brain patterns in humans that appear to underlie "resilient coping," the healthy emotional and behavioral responses to stress that help some people handle stressful situations better than others. People encounter stressful situations and stimuli everywhere, every day, and studies have shown that long-term stress can contribute to a broad array of health problems. However, some people cope with stress better than others, and scientists have long wondered why. The new study, by a team of researchers at Yale University, New Haven, Connecticut, is now online in the Proceedings of the National Academy of Sciences. "This important finding points to specific brain adaptations that predict resilient responses to stress," said George F.

Almost Six Million U.S. Adults Experienced Marijuana Use Disorder in Past Year
Almost six million American adults experienced marijuana use disorder in the past year, according to a study by scientists at the National Institutes of Health (NIH). Symptoms of marijuana use disorder include cravings, developing a tolerance, and experiencing withdrawal symptoms, including inability to sleep, nervousness, anger, or depression, within a week of stopping heavy use, according to Medical Daily. The study, published in the American Journal of Psychiatry, found 6.3 percent of adults acquire a dependence on marijuana at some point in their lives, and 2.5 percent of adults have experienced marijuana use disorder in the past year. The researchers interviewed more than 36,000 adults about their drug and alcohol use, and related psychiatric conditions. They found marijuana use disorder is about twice as common in men than women. Younger people are much more likely than those over 45 to experience the disorder. The researchers note cannabis dependence is strongly and...

Spotlight on Alcohol Use and Older Adults
The National Institutes of Health (NIH) notes that adults of any age can have problems with alcohol. In general, older adults don't drink as much as younger people, but they can still have trouble with drinking. As people get older, their bodies change. They can develop health problems or chronic diseases. They may take more medications than they used to. All of these changes can make alcohol use a problem for older adults A recent article in the Palm Beach Post noted that older Americans are collectively becoming one of the nation’s biggest abuse problems, and this is according to several recent studies. This population is even outpacing binge-drinking college kids whose drinking habits have long been a documented concern. According to a 2014 study in the peer-reviewed specialty journal, Addiction, there are an estimated 2.8 million older adults in the United States meet the criteria for alcohol abuse. By the...
