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 Birth-control pills affect the body's ability to regulate stress, study suggests (via sciencedaily.com) Original source
A new study suggests that birth-control pills negatively impact women's stress response.
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 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 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 New genetic target for male contraception identified (via sciencedaily.com) Original source
Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
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 Positive experiences in close relationships are associated with better physical health, new research suggests (via sciencedaily.com) Original source
Social relationships influence physical health, but questions remain about the nature of this connection. New research suggests that the way you feel about your close relationships may be affecting the way your body functions.
Published Study finds worrying about election stress can harm your health -- and what you can do about it (via sciencedaily.com) Original source
New research finds that simply anticipating stress related to political elections causes adverse physical health effects. However, the study also finds there is something people can do to mitigate those negative health effects.
Published Study finds similar association of progestogen-only and combined hormonal contraceptives with breast cancer risk (via sciencedaily.com) Original source
There is a relative increase of 20% to 30% in breast cancer risk associated with both combined and progesterone-only contraceptives, whatever the mode of delivery, though with five years of use, the 15-year absolute excess incidence is at most 265 cases per 100,000 users, according to a new study.
