Boosting a single molecule in the brain can change 'dispositional anxiety,' the tendency to perceive many situations as threatening, in nonhuman primates, researchers from UC Davis and UW-Madison have found. The molecule, neurotrophin-3, stimulates neurons to grow and make new connections.
For children and teens with migraine, the pain and symptoms that accompany migraine attacks can be debilitating, resulting in missed school days, absence from social or sporting events, and affected home activities. Now the American Academy of Neurology (AAN) and the American Headache Society have developed two guidelines that include recommendations for preventing and treating migraine in children and teens.
A comprehensive dementia care program staffed by nurse practitioners working within a health system improves the mental and emotional health of patients and their caregivers.
Very frequent use of social media may compromise teenage girls' mental health by increasing exposure to bullying and reducing sleep and physical exercise, according to an observational study of almost 10,000 adolescents aged 13-16 years studied over three years in England between 2013-2015, published in The Lancet Child & Adolescent Health journal. The impact on boys' mental health appears to mainly be due to other mechanisms, not revealed by this study.
Exposure to violence, social conflict, and other stressors increase risk for psychiatric conditions such as depression and post-traumatic stress disorder. A new paper suggests that the behavior of oligodendrocytes -- the glial cells that produce the myelin sheath that protects nerve fibers -- plays a critical role in determining whether we succumb to or tolerate stress.
This research letter uses survey data to report on perceived bullying by internal medicine residents during training.
USC researchers looked at 'emotion-induced blindness,' which refers to distractions caused by emotionally arousing stimuli. In four experiments using a quickly presented sequence of images, they examined how older adults prioritize emotional information. They found both younger and older adults demonstrated emotion-induced blindness, but older adults were more distracted by positive information and less distracted by negative information.
Not a good mix: A researcher from the University of Houston has found that adults who combine prescription opioids for severe pain and cannabis report elevated anxiety and depression symptoms, with no increased pain reduction.
People generally think of stress and anxiety as negative concepts, but while both stress and anxiety can reach unhealthy levels, psychologists have long known that both are unavoidable -- and that they often play a helpful, not harmful, role in our daily lives, according to a presentation at the annual convention of the American Psychological Association.
University of Houston assistant professor of electrical engineering Rose T. Faghih reports that the tiny beads of sweat, which appear in patients experiencing PTSD or other neuropsychiatric disorders, can be measured and used to design and more responsive brain stimulator for therapy.
