Published Posttraumatic brain activity predicts resilience to PTSD
(via sciencedaily.com) After a traumatic experience, most people recover without incident, but some people -- between 2% and 10% -- develop posttraumatic stress disorder (PTSD), a mental health condition that can cause debilitating symptoms of anxiety due to emotional dysregulation. PTSD symptoms are present in up to 40% of trauma survivors in the acute aftermath of trauma, but full-blown PTSD develops in only a small subset of cases. Early identification of those at risk is critical for both early treatment and possible prevention.
Published Your body's own cannabinoid molecules calm you during stress
(via sciencedaily.com) When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.
Published Active children are more resilient
(via sciencedaily.com) The school year has hardly begun and the first exams are already approaching. According to findings by researchers from the University of Basel, school children cope better with the stress if they get plenty of daily exercise.
Published Stress and insomnia linked to irregular heart rhythms after menopause
(via sciencedaily.com) A study of more than 83,000 questionnaires by women ages 50-79, found more than 25% developed irregular heart rhythms, known as atrial fibrillation, which may increase their risk for stroke and heart failure.
Published High-quality sleep promotes resilience to depression and anxiety
(via sciencedaily.com) Research has shown quality sleep can help bolster resilience to depression and anxiety.
Published Neural signature for borderline personality disorder identified
(via sciencedaily.com) Original source A new study of a brain region called the rostro-medial prefrontal could potentially advance diagnosis and therapies for Borderline Personality Disorder (BPD).
Published Poor sense of smell linked to increased risk of depression in older adults
(via sciencedaily.com) Original source In a study that followed more than 2,000 community-dwelling older adults over eight years, researchers say they have significant new evidence of a link between decreased sense of smell and risk of developing late-life depression.
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 A student's poor eating habits can lead to a lifetime of illness
(via sciencedaily.com) Original source A researcher is cautioning that a person's poor eating habits established during post-secondary studies can contribute to future health issues including obesity, respiratory illnesses and depression.
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 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.
