Posttraumatic stress disorder (PTSD) has been associated with military activities for as long as wars have been fought -- but this disorder was only named in the 1980s. A new Yale paper published April 16, 2018 in Chronic Stress documents a different kind of war -- a war of words -- that has been fought over the name of the disorder, and may have slowed clinical and scientific progress on the disorder.
There's increasing physiological evidence connecting breathing patterns with the brain regions that control mood and emotion. Now researchers have added neurons associated with the olfactory system to the connection between behavior and breathing. Connecting patterns in these interactions may help explain why practices such as meditation and yoga that rely on rhythmic breathing can help people overcome anxiety-based illnesses.
In a student-led study, one hour of mindfulness meditation shown to reduce anxiety and some cardiovascular risk markers.
A study of nearly half a million people has revealed that muscular strength, measured by handgrip, is an indication of how healthy our brains are. The study, published in Schizophrenia Bulletin, also showed that maximal handgrip was strongly correlated with both visual memory and reaction time in over one thousand people with psychotic disorders such as schizophrenia.
Researchers from Brigham and Women's Hospital are leveraging gene-editing tools and mini-organs grown in the lab to study the effects of DISC1 mutations in cerebral organoids -- 'mini brains' -- cultured from human stem cells.
Reducing severity of PTSD symptoms long-term holds significant public-health and economic implications.
A study among British airline pilots shows that 20 percent of them have scores on a burnout scale that are comparable to those of people that are under burnout treatment. Surprisingly, the same study shows that only one of the 1147 pilots that participated, did not meet the performance standards at the regular flight simulator training. The authors argue that airline companies need to offer better support and facilities to their pilots to help them cope with their stressful jobs.
New research suggests that it is not just the victims of cyberbullying that are more vulnerable to suicidal behaviours, but the perpetrators themselves are also at higher risk of experiencing suicidal thoughts and behaviours.
More students report carrying guns in Chicago than in New York or Los Angeles, a new Northwestern Medicine study shows. The findings provide historical background for Chicago's 2016 spike in gun violence, which occurred mostly among youth and young adults.
A new study of trial court judges suggests these arbiters of the law sometimes let their personal ideas about gender roles influence their decision-making. The findings, which are part of a broader study of judicial behavior, revealed that the judges were just as likely as laypeople to discriminate -- in ways that harmed both men and women -- in decisions involving child custody or workplace discrimination cases related to family caregiving duties.
