After languishing for years in the shadows of psychiatry's definition of adult depression, irritability is finally getting some respect again. It's about damned time, you might say. A new study has found that people suffering a major depressive episode who report they have become grouchy, hostile, grumpy, argumentative, foul-tempered or angry will likely have a "more complex, chronic and severe form" of major depressive disorder than those who...

Getting a good grip on your health may mean … getting a good grip. The force you can muster when squeezing an object or a weight doesn't only reveal how strong your hand and arm are. It can be a measure of overall muscle function and — according to one recent study — even portend how long you're likely to live. That's not as nutty as it seems, says Richard Bohannon, a professor of physical therapy at the University of Connecticut. "Grip strength reflects your overall muscle status and a general sense of how much muscle mass you have" he says.

A daily glucosamine drink supplement failed to prevent deterioration of knee cartilage, reduce bone bruises or ease knee pain, according to a recent short-term study of the popular, if controversial, dietary product. In a paper published Tuesday in the journal Arthritis & Rheumatology , authors studied the effects of glucosamine hydrochloride on a group of 201 adults for six months. "Our study found no evidence that drinking glucosamine supplement reduced knee cartilage damage, relieved pain or improved function in individuals with chronic knee pain," said the study's lead author, Dr. C. Kent Kwoh, professor of medicine and medical imaging at the University of Arizona College of Medicine.

By quizzing small children about the first events they remember — a cousin misbehaving, a trip to a grocery store, a mother's bribe of red and green licorice — researchers have discovered that the earliest memories of children shift as they get older, and don't solidify into the first memories carried throughout life until about age 10. The research, published Wednesday in the journal Child Development, could help psychologists better understand...

Don't press the like button: Facebook is a bummer that makes us feel worse about our lives, according to new research. Facebook users in a study led by the University of Michigan wound up feeling worse about themselves after two weeks, and their moment-to-moment mood darkened the more they browsed the social medium. It didn't seem to matter how big their network was, how supportive they thought their friends were, nor why they went to Facebook in the first place, according to the study published online Wednesday in PLOS One . "We were able to show on a moment-to-moment basis throughout the day how people's mood fluctuated depending on their Facebook usage,” said University of Michigan social psychologist Ethan Kross, lead author of the study.

People who are socially isolated are more likely to die prematurely, regardless of their underlying health issues, according to a study of the elderly British population. The findings, published online Monday in the Proceedings of the National Academy of Sciences, showed that when mental and physical health conditions were factored out, the lack of social contact continued to lead to early death among 6,500 men and women tracked over a seven-year period. "They're dying of the usual causes, but isolation has a strong influence," said study author Andrew Steptoe, an epidemiologist at University College London.
