Objective: Two of the most common and costly mental health diagnoses among military veterans who served in the post-9/11 conflicts in Afghanistan and Iraq are posttraumatic stress disorder (PTSD) and depression, but over half of veterans who screen positive for these problems do not seek treatment. A key barrier is self-stigma of mental illness. Mindfulness has shown promise as an explanatory...
Law enforcement officers are regularly exposed directly and indirectly to a wide variety of traumatic stressors, which take place against a backdrop of high levels of organizational stressors. Consequently, this group is at elevated risk for posttraumatic stress disorder (PTSD) and other negative physical and mental health outcomes, yet there are few empirically supported interventions to...
Objective: The present study investigated the ways in which dispositional mindfulness is related to posttraumatic stress disorder (PTSD) symptoms and job burnout among firefighters by considering the role of perceived social support. Method: A total of 409 Chinese firefighters completed the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition, the Maslach...
Introduction Combat veterans are at high risk for the development of posttraumatic stress disorder (PTSD) and substance use disorders. Ketamine has been shown to be an effective treatment for numerous mental health disorders, although research on its efficacy in combat-related PTSD in veterans is very limited. Methods The study population consisted of 30 US military veterans with combat-related...
Posttraumatic stress disorder (PTSD) is a debilitating mental disorder affecting numerous U.S. citizens, but conventional interventions have shown limited success in treating PTSD symptoms (e.g., high dropout rates). Various meditative techniques have been used as alternative interventions to treat PTSD, demonstrating that these interventions have strong potential to improve symptoms and...
Posttraumatic stress disorder (PTSD) is often difficult to treat, and many patients do not achieve full remission. Complementary and integrative health approaches, such as mindfulness meditation, are intended to be integrated with evidence-based treatment. This study examined the efficacy of mindfulness-based stress reduction (MBSR) in the treatment of PTSD in U.S. military veterans. Veterans...
Sleep significantly changes across the lifespan, and several studies underline its crucial role in cognitive functioning. Similarly, mental activity during sleep tends to covary with age. This review aims to analyze the characteristics of dreaming and disturbing dreams at different age brackets. On the one hand, dreams may be considered an expression of brain maturation and cognitive...

Neuroimaging studies in the area of mindfulness research have provided preliminary support for the idea of fear extinction as a plausible underlying mechanism through which mindfulness exerts its positive benefits. Whilst brain regions identified in the fear extinction network are typically found at a subcortical level, studies have also demonstrated the feasibility of cortical measures of the...
Individuals with post-traumatic stress disorder (PTSD) typically experience states of reliving and hypervigilance; however, the dissociative subtype of PTSD (PTSD+DS) presents with additional symptoms of depersonalization and derealization. Although the insula is critical to emotion processing, its association with these contrasting symptom profiles is yet to be fully delineated. Accordingly,...
Research on yoga interventions for post-traumatic stress disorder (PTSD) is plentiful, but none to date have studied the neural effects and benefits of a yogic practice on the default mode network (DMN) in PTSD.Common features of PTSD, such as mind-wandering and emotional dysregulation, are linked to altered neural functioning of the DMN due to initial trauma exposure.Symptom severity is also...
Posttraumatic stress disorder is a prevalent mental health condition with substantial impact on daily functioning that lacks sufficient treatment options. Here we evaluate six phase 2 trials in a pooled analysis to determine the study design for phase 3 trials of MDMA-assisted psychotherapy for PTSD. Six randomized, double-blind, controlled clinical trials at five study sites were conducted...
Recent research suggests that psychedelic drugs can be powerful agents of change when utilized in conjunction with psychotherapy. Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy has been studied as a means of helping people overcome posttraumatic stress disorder, believed to work by reducing fear of traumatic memories and increasing feelings of trust and compassion toward others,...
Many biological systems are altered in association with Posttraumatic Stress Disorder (PTSD) and resilience. However, there are only few approved pharmacological treatments for PTSD, and no approved medications to enhance resilience. This paper provides a critical review of select neurobiological findings in PTSD and resilience, and also of pharmacologic approaches that have emerged from this...
This article explores incorporating 3,4-methylenedioxymethamphetamine (MDMA) as an adjunct in emotionally focused couples therapy (EFT) with clients in which at least one participant has endured a traumatic experience and reports symptoms of post-traumatic stress disorder (PTSD). Despite classification as a Schedule I drug on the Controlled Substances Act (CSA), in 2017 the U.S. Food and Drug...

BACKGROUND. Police officers are exposed daily to high levels of organizational and operational stressors that have a negative impact on health and well-being outcomes. This population has elevated rates of cardiovascular disease, sleep disorders, symptoms of depression and post-traumatic stress disorder (PTSD), and suicide. Although there are few empirically supported effective stress reduction...
Post-traumatic stress disorder (PTSD) is a debilitating, highly prevalent condition. Current clinical practice guidelines recommend trauma-focused psychotherapy (eg, cognitive processing therapy; CPT) as the first-line treatment for PTSD. However, while these treatments show clinically meaningful symptom improvement, the majority of those who begin treatment retain a diagnosis of PTSD...
Mindfulness approaches to promoting resilience and mental fitness within the UK Armed Forces have very recently emerged against a backdrop of studies from abroad, leading to a plethora of initiatives. These studies have used biological and cognitive markers of sustained attention and the human stress response, before and after training, in the period prior to deployment and made assertions of...
Serotonin, one of the first neurotransmitters to be identified, is an evolutionarily old molecule that is highly conserved across the animal kingdom, and widely used throughout the brain. Despite this, ascribing a specific set of functions to brain serotonin and its receptors has been difficult and controversial. The 2A subtype of serotonin receptors (5-HT2A receptor) is the major excitatory...
There is considerable interest in developing complementary and integrative approaches for ameliorating posttraumatic stress disorder (PTSD). Compassion meditation (CM) and loving-kindness meditation appear to offer benefits to individuals with PTSD, including symptom reduction. The present study was a pilot randomized controlled trial of CM for PTSD in veterans. The CM condition, an adaptation...
