(Reuters Health) - People who have disrupted sleep cycles or less variation in their activity levels around the clock may be more likely to have depression, bipolar disorders and other mental health issues, a UK study suggests. Past research has found that people with a circadian rhythm, or biological clock, that’s out of step with their daily routines - like split shift or night shift workers - can have an increased risk of emotional, behavioral and psychological problems. The current study examined 24-hour activity levels for 91,015 participants who agreed to wear accelerometers on their wrists for one week in 2013-2014 and completed mental health surveys a few years later. Researchers focused on so-called relative amplitude, or how much people’s activity levels varied between their busiest and most restful portions of a 24-hour cycle. They scored circadian amplitude from zero to 1, with higher values reflecting a clearer distinction between the least and most active … [Read more...] about Disrupted sleep cycles linked with mood disorders
Art Institute of Chicago "Self-Portrait" by Vincent Van Gogh, 1887 In an article published this week in Aeon, Christa Taylor, a postdoctoral researcher at the Yale University Center for Emotional Intelligence, takes a fascinating look at the myth of the “mad genius” — the common belief that creativity is inherently linked to depression and other mood disorders. As Taylor points out, the idea that a mental disorder is a sign of creativity first emerged during the Romantic Era and has been part of popular lore ever since. But is there any good scientific evidence of this connection? Trying to answer that question raises some “knotty, multi-layered” research-related problems, says Taylor. “It is not as straightforward as just seeing if ‘creativity’ is correlated with ‘mood disorder.’ ” It’s important, however, that we get a clearer answer to the question, she stresses. The perpetuation of the myth may be … [Read more...] about Is there a link between creativity and mood disorders? Well, it’s a thorny, nuanced issue.
A disrupted body clock may boost the risk of developing mood problems ranging from garden-variety loneliness to severe depression and bipolar disorder, researchers said Wednesday. The largest study of its kind, involving more than 91,000 people, also linked interference with the body's "circadian rhythm" to a decline in cognitive functions such as memory and attention span, The AFP reported. The brain's hard-wired circadian timekeeper governs day-night cycles, influencing sleep patterns, the release of hormones and even body temperature. Earlier research had suggested that disrupting these rhythms can adversely affect mental health, but was inconclusive: most data was self-reported, participant groups were small, and potentially data-skewing factors were not ruled out. For the new study, an international team led by University of Glasgow psychologist Laura Lyall analysed data -- taken from the UK Biobank, one of the most complete long-term health surveys ever done -- on 91,105 … [Read more...] about Disrupted Body Clock Linked to Mood Disorders: Study
While depression is recognizable to many, mania may be not be as familiar. Oftentimes bipolar disorder can wreak havoc with an individual's life, but it may not be obvious to others that something is wrong. “It’s a great misconception that you are a basket case if you have bipolar disorder,” Jamison said who has been public about her struggle with bipolar disorder. “I am someone who has specialized in this all my professional life and I’ve been around specialists who treat mood disorders. When I went public, most of my colleagues were shocked. It can be deceptive in that respect.” “It’s a great misconception that you are a basket case if you have bipolar disorder. When I went public, most of my colleagues were shocked. It can be deceptive in that respect.” “It’s a great misconception that you are a basket case if you have bipolar disorder.

April 9, 2018 Michael Joyce is a writer-producer with HealthNewsReview.org and tweets as @mlmjoyce A Wall Street Journal article published last week (‘The Food That Helps Battle Depression‘) had this subheading: “The right kind of diet may give the brain more of what it needs to avoid depression, or even to treat it once it’s begun” It’s a bold claim for which the story provides little in the way of compelling evidence. Experts we spoke to said the story goes way beyond the science in this emerging field. Allen Frances, MD “The fact that almost no research has been done on the topic gives free rein to wildly speculative and potentially harmful hype,” said Allen Frances, MD, a former chairman of the psychiatry department at Duke University. “It makes great sense to have a healthy diet for many reasons, but preventing or treating depression would not rate high among them. Except for a placebo effect, eating your way out of … [Read more...] about Food for mood: A Wall Street Journal article makes bold claims with little evidence
