A study from the National Institute on Alcohol Abuse and Alcoholism found that nonmedical prescription opioid use more than doubled among US adults from 2001-2002 to 2012-2013, affecting nearly 10 million Americans. This increase is linked to a substantial rise in opioid use disorder, with symptoms such as tolerance, withdrawal, and im...

The test combines genetic testing with brain imaging to identify a specific alteration in the expression of microRNA miR-29c, which is linked to slow recovery from stress.
Researchers discovered that soldiers with post-traumatic stress disorder (PTSD) are more 'tuned' to perceive threatening facial expressions than people without PTSD. This is caused by more over-connected brain circuits, particularly in the amygdalae and ventral medial prefrontal cortex.
Researchers found that PTSD patients exhibit heightened brain activity when viewing non-threatening images similar to their trauma, suggesting a generalized response. The study identifies key brain regions involved in this process, including the fusiform gyrus and locus coeruleus.
New research suggests oxytocin may trigger anxiety in stressed females, unlike males where it increases social motivation. The hormone also had no effect on non-stressed females.
A new study by Uppsala University researchers found that posttraumatic stress disorder is caused by an imbalance between two neurochemical signalling systems: serotonin and substance P. The severity of symptoms depends on the degree of imbalance, not just one system.
A recent study found nearly 18% of returning veterans experience sexual functioning difficulties, with depression and post-traumatic stress disorder being major contributing factors. The study's authors emphasize the need for easy access to effective care and open discussion of sexual health concerns among veterans.
Studies reveal high rates of male military sexual trauma due to stigma and shame, affecting mental health outcomes. Female veterans who experienced assault are also at risk of PTSD and delayed seeking help.

A randomized trial found that mindfulness-based stress reduction therapy resulted in greater improvement in self-reported PTSD symptom severity compared to present-centered group therapy. The study suggests that this type of intervention may be an acceptable alternative for veterans with poor adherence to existing treatments.
A new study suggests a cutting-edge computer program capable of alleviating PTSD symptoms by reducing fluctuations in attention towards and away from perceived threats. The program, targeting basic cognitive processes, produced significant reductions in severe PTSD symptoms with a similar success rate as cognitive behavioral therapy.
A new study examined brain networks in veterans with trauma exposure using functional magnetic resonance imaging and graph theory tools. The researchers found that veterans with more severe PTSD re-experiencing symptoms showed weaker connectivity in two brain networks, including the hippocampus and prefrontal cortex.
A new study at Case Western Reserve University's Frances Payne Bolton School of Nursing found that coping by avoidance when making decisions for relatives in ICU can lead to PTSD. The study surveyed 77 people and found 42% had clinically significant PTSD symptoms, with death of the patient being a strong predictor.
Researchers find that presenting a new outcome instead of omitting an expected threat can lead to more effective fear extinction in both rats and humans. The study's findings have implications for the treatment of anxiety disorders, including posttraumatic stress disorder and phobias.
A study published in Neuropsychopharmacology found that cortisol enhances the consolidation of emotional memories, particularly in individuals with anxiety and Post-Traumatic Stress Disorder (PTSD). Cortisol levels can strengthen memories of traumatic experiences during both initial formation and reconsolidation after memory retrieval.
A new study suggests that virtual reality therapy may help people with alcohol dependence reduce their craving for alcohol. The therapy involves exposing patients to situations that trigger fear and anxiety, then teaching them to manage those situations in real life.

Aftermath stress was the strongest predictor of post-traumatic stress symptoms, with insurance company issues being a major contributor.
A large study by Boston University School of Medicine researchers found no evidence of an association between Post Traumatic Stress Disorder (PTSD) and cancer incidence. This contradicts plausible theories suggesting a link between stress and cancer, but is consistent with previous population-based studies.

Those with outgoing personalities were also more at risk. The study highlights the need for support and awareness about the risks of viewing traumatic content online.
A new study by Ludwig-Maximilians-Universität München attributes mild cognitive defects in breast cancer patients to post-traumatic stress induced by diagnosis, not chemotherapy side-effects. The study found pretreatment cognitive impairment in breast cancer patients was due to stress associated with the disease.
A new study found that cancer-related post-traumatic stress is associated with very limited cognitive impairment before treatment among newly diagnosed breast cancer patients. The study, published in the JNCI Journal of the National Cancer Institute, analyzed data from 166 breast cancer patients and 60 matched controls.
PTSD survivors often experience sexual dysfunction due to biological and cognitive processes related to traumatic stress. The condition disrupts trust, safety, and emotional connection, associating arousal with threat.
A recent study found that family support during deployment significantly reduces suicidal thoughts in veterans. The research, published in Anxiety, Stress and Coping, highlights the importance of treating mental health symptoms to prevent suicidal ideation.

The study suggests that these molecular signatures may be used to predict who is at risk of developing PTSD.
Researchers found that early post-traumatic stress symptoms are the strongest predictors of later disability in military personnel with mild brain injuries. A study evaluated 38 patients with mild blast-related brain injury and 34 controls, showing that mental health assessments soon after injury were more predictive of long-term disab...
A new therapy, TIPSS, developed by Anka Vujanovic aims to treat both post-traumatic stress disorder (PTSD) and substance use disorders. The study focuses on an integrated treatment that combines elements of standard cognitive-behavioral therapy with a focus on PTSD symptoms.
A study of 159 women found that those with high mastery and social support were less likely to develop major depressive disorder after assault exposure. Mastery and posttraumatic growth were also associated with recovery from trauma-related psychiatric disorders.
A recent study suggests that brain circuitry for fear retrieval shifts over time, potentially worsening symptoms of anxiety disorders. The discovery could change scientists' view of post-traumatic stress disorder and inform the development of new treatments.
A new study offers tailored approaches to help spouses reintegrate and rebuild their relationship after a partner's combat deployment. Strategies include emotional acceptance, effective communication, and maintaining trust.
Among survivors of the 2011 Utøya Island terrorist attack, most perceived contact with media as a positive experience. However, negative evaluations and regrets about participation were found to be associated with post-traumatic stress reactions.
A telemedicine-based collaborative care model successfully engaged rural veterans with PTSD in evidence-based psychotherapy, improving clinical outcomes. The study found that patients who attended eight or more sessions of cognitive processing therapy experienced significant improvements in PTSD severity.
A study by Jonathan Purtle found that federal legislation addressing PTSD has predominantly focused on military personnel, with over 90% of mentions targeting military personnel or combat exposure. However, PTSD affects a significantly larger civilian population due to its prevalence in non-military traumatic events.
Research suggests that guidelines limiting duration of overseas deployment in UK troops may have prevented 138 cases of PTSD, among other mental health issues. The Harmony Guidelines, introduced in 2006, limited tours to 13 months or less over a 3-year period.
A Stanford/VA study found that pregnant women with post-traumatic stress disorder (PTSD) are at a higher risk of giving birth prematurely. The study analyzed over 16,000 births to female veterans and found that having PTSD in the year before delivery increased the risk by 35 percent.
