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 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 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 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 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 Early signs that may help predict ADHD risk (via sciencedaily.com) Original source
Information available at birth may help to identify children with higher likelihood of developing ADHD, according to new research.
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 Time out: We all need a three-day weekend (via sciencedaily.com) Original source
As a four-day work week is trialed in countries across the globe, health researchers say they're 'all in' when it comes to a long weekend, especially as new empirical research shows that the extra time off is good for our health.
Published Men and women have different obesity drivers, pointing to the need for tailored interventions (via sciencedaily.com) Original source
A new study finds sex-specific brain signals that appear to confirm that different drivers lead men and women to develop obesity. The study combined data from several modes of MRI with patients' clinical features and personal histories to identify sex-specific mechanisms in the brain underlying obesity.
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.
