Published A subtype of depression identified (via sciencedaily.com) Original source
Using surveys, cognitive tests and brain imaging, researchers have identified a type of depression that affects about a quarter of patients. The goal is to diagnose and treat the condition more precisely.
Published Chronic stress-related neurons identified (via sciencedaily.com) Original source
Researchers have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for estrogen, which could explain why women as a group are more sensitive to stress than men.
Published Serotonin booster leads to increased functional brain connectivity (via sciencedaily.com) Original source
Cognitive deficits accompany mood disorders and other psychiatric conditions, often with debilitating effects. Limited treatments currently exist, but studies in animals and humans have pointed to drugs such as the laxative prucalopride that activate serotonin receptors as a potential therapeutic for the symptoms. It has remained unclear, however, how the medication affects resting brain activity. Now, a new study examines the drug's effects in healthy human adults.
Published New study links contraceptive pills and depression (via sciencedaily.com) Original source
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
Published New research identifies cells linking chronic psychological stress to inflammatory bowel disease (via sciencedaily.com) Original source
For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).
Published How chronic stress drives the brain to crave comfort food (via sciencedaily.com) Original source
Stress can override natural satiety cues to drive more food intake and boost cravings for sweets.
Published Obesity increases risk of mental disorders throughout life (via sciencedaily.com) Original source
Being obese significantly increases the chances of also developing mental disorders. This applies to all age groups, with women at higher risk than men for most diseases.
Published Researchers treat depression by reversing brain signals traveling the wrong way (via sciencedaily.com) Original source
A new study has revealed how magnetic stimulation treats severe depression: by correcting the abnormal flow of brain signals.
Published AI voice coach shows promise in depression, anxiety treatment (via sciencedaily.com) Original source
A study found changes in patients' brain activity along with improved depression and anxiety symptoms after using Lumen.
Published Potential found to counter depression by restoring key brain rhythm (via sciencedaily.com) Original source
A new study in mice and rats found that restoring certain signals in a brain region that processes smells countered depression.
Published Anti-depressant agent KNT-127 reduces stress as well as depression (via sciencedaily.com) Original source
Depression is a condition affecting millions across the globe. However, efficient drugs with minimal adverse effects are scarce. Now, researchers have reported how KNT-127, a delta opioid receptor agonist, quickly and efficiently reduces classic parameters of depression in a mouse model. This anti-depressant agent exhibits the dual nature of being a stress reliever and an anti-depressant and could broaden the potential of existing treatments.
Published Sleep phase can reduce anxiety in people with PTSD (via sciencedaily.com) Original source
A new study shows that sleep spindles, brief bursts of brain activity occurring during one phase of sleep and captured by EEG, may regulate anxiety in people with post-traumatic stress disorder (PTSD).
Published Stress increases Alzheimer's risk in female mice but not males (via sciencedaily.com) Original source
Stress causes the levels of Alzheimer's proteins to rise in females' brains but not males' brains, according to a new study. This difference may contribute to women's greater risk of developing Alzheimer's disease.
Published Mental imagery a helpful way to distract teens from negative thought patterns (via sciencedaily.com) Original source
For adolescents who may get stuck in negative thought spirals, refocusing on mental imagery is a more effective distraction than verbal thoughts.
Published Problems with 'pruning' brain connections linked to adolescent mental health disorders (via sciencedaily.com) Original source
Problems with the brain's ability to 'prune' itself of unnecessary connections may underlie a wide range of mental health disorders that begin during adolescence, according to research published today. The findings may help explain why people are often affected by more than one mental health disorder, and may in future help identify those at greatest risk.
Published Impact of maternal stress during pregnancy on child's health (via sciencedaily.com) Original source
New research examines the impact that maternal stress during pregnancy has on the neuro-development of babies.
Published Detecting stress in the office from how people type and click (via sciencedaily.com) Original source
Researchers have developed a model that detects workplace stress just by how people type and move their computer mouse. This might enable employees to prevent chronic stress early on.
Published Teachers who struggle to cope with stress report far lower job satisfaction (via sciencedaily.com) Original source
As teacher shortages continue to worsen across the United States, a new study gives insight into why so many stressed and burnt-out teachers are leaving the profession. The study found teachers who struggle to cope with the stress of their job report far lower job satisfaction compared to teachers who find ways to manage the pressure.
Published Study examines how social rank affects response to stress (via sciencedaily.com) Original source
Scientists say their study could shed light on stress-related mental illnesses but that more research is needed.
Published Newly discovered trigger for major depression opens new possibilities for treatments (via sciencedaily.com) Original source
The simple amino acid glycine looks to be a previously unknown contributor to depression.
