A study shows that unemployment stress is more closely tied to local green space than age, income, or deprivation. The presence of parks and woodland in economically deprived areas can help people cope with job losses and reduce cortisol levels.
A study led by Dr. Charles Marmar found that police recruits with higher cortisol awakening responses were more likely to experience acute stress symptoms in response to trauma years later. The study suggests that measuring cortisol levels could be a potential indicator for identifying those at high risk for PTSD.
Researchers at UC Berkeley found that dream sleep helps process emotional experiences, removing the edge from painful memories. During REM sleep, stress neurochemicals are suppressed, allowing the brain to connect and integrate memories in a more rational state.

The study highlights areas for improvement, including increasing evidence-based treatments and addressing regional variations in care.
A study published in European Neuropsychopharmacology found that administering a single dose of cortisone up to six hours after traumatic event reduces the likelihood of developing PTSD by 60%. This natural approach may circumvent the harm caused by other pharmaceuticals and prevent the consolidation of traumatic memories.
Researchers found that administering synthetic marijuana helps block PTSD-like symptoms in rats after experiencing trauma. The study suggests a 'window of opportunity' for treatment, which may be longer for humans due to their lifespan.

A survey of 4,639 Virginia Tech students found that 15.4% experienced high levels of posttraumatic stress three to four months after the shootings. The study suggests that social relationships and anxiety about friend safety were key factors in symptoms of posttraumatic stress.
A randomized controlled trial found that narrative exposure therapy significantly reduced PTSD symptoms in former child soldiers in Uganda compared to other therapies. The treatment was conducted by community-based lay therapists without a mental health background, demonstrating its feasibility and effectiveness.
The study found that risk factors for PTSD among OEF/OIF male veterans were similar to those observed in Vietnam veterans, but identified novel mechanisms of risk for OEF/OIF female veterans. Family relationships during deployment played a more prominent role in explaining PTSD in female veterans than in male veterans.
Researchers found that ghrelin hormone is required for prolonged psychosocial stress to promote preference and intake of high-fat food in mice. This discovery could lead to new therapeutic targets for curbing stress-related food behavior.
A groundbreaking study published in Journal of Abnormal Psychology suggests female military service-members are equally resilient to combat-related stress as men. The research, conducted by Boston University School of Medicine, analyzed the mental health of veterans returning from deployment to Afghanistan or Iraq.
A new study found that frequent communication through letters and emails with spouses during deployment can protect against PTSD symptoms in happily married soldiers. However, this benefit only applies to soldiers with higher levels of marital satisfaction.

The technique produced a 50% reduction in PTSD symptoms in just eight weeks, with long-term changes in sympathetic nervous system activity.
A study published in the Journal of Clinical Endocrinology & Metabolism found that metyrapone, a stress hormone-reducing drug, can impair memory recall of negative events by manipulating cortisol levels close to formation. This could lead to a better understanding of how to treat post-traumatic stress disorder
Weizmann Institute scientists discover that adverse experiences can impair perception, making it harder to distinguish between similar stimuli. This finding may contribute to the development of anxiety disorders like post-traumatic stress syndrome.
A study by University of Washington psychologists found no correlation between positive emotions and stress/depression in Asian college students, suggesting therapies focusing on positivity may not work. Instead, mindfulness approaches that acknowledge both good and bad emotions may be more effective.
A team of neuroscientists has discovered a critical 'chemical pathway' in the brain that triggers our response to stress. The study found that increasing production of a protein called neuropsin in the amygdala leads to increased activity and vulnerability to stress.
A recent study suggests that affectionate communication, such as hugging, can help individuals with high levels of alexithymia form more fulfilling relationships and reduce anxiety. Researchers surveyed 921 people and found that sharing affection reduces the negative impact of alexithymia on relationships.
Studies found that exercise prevents telomere stress and cell aging, suggesting a link between physical activity and healthier cells. Telomeres measure cell age and health, with shorter lengths linked to diseases like cancer and cardiovascular disease.
A new study finds that larger hippocampal volumes are linked to recovery from post-traumatic stress disorder (PTSD), implying that the hippocampus may play a role in reversing damage caused by chronic stress. The research suggests that treatment for PTSD could be viewed as a form of brain restoration, rather than just symptom relief.
Research identifies four major PTSD symptoms with varying effects on quality of life, challenging common assumptions about the disorder's impact. Symptoms tied to heightened arousal, such as trouble sleeping and irritability, were found to have a significant association with lower quality of life among PTSD patients.
A study from Emory University and the University of Vermont has found a link between high blood levels of hormone PACAP and post-traumatic stress disorder (PTSD) in women, but not men. The hormone modulates central nervous system activity, metabolism, and immune function.
