Abstract Objectives Nonattachment, defined as the capacity to relate to internal experiences, identities, and external circumstances without clinging, avoidance, or over-identification, has been associated with reduced psychological distress and enhanced well-being, yet its deliberate cultivation within trauma-focused interventions remains underexplored. This study evaluated Nonattachment for...

Abstract Major depressive disorder (MDD) and post-traumatic stress disorder (PTSD) are prevalent, chronic, and disabling mental health conditions which are difficult to treat. Ketamine has demonstrated effect for improving depression and PTSD symptoms independently but reports often overlook focused comorbid improvement of these symptoms within individuals. To address this, we assessed...

Abstract Post-traumatic stress disorder (PTSD) is a highly prevalent, debilitating psychiatric condition. Existing treatments are ineffective for many patients. 3,4- methylenedioxymethamphetamine (MDMA)-assisted psychotherapy has demonstrated substantial clinical efficacy but relies on prolonged, resource-intensive therapeutic protocols that limit scalability and accessibility. Here, we...

3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy has emerged as a potential strategy to treat posttraumatic stress disorder (PTSD). We conducted a national serial cross-sectional study of U.S. Veterans with PTSD from January 1, 2018, to December 31, 2023, to quantify the prevalence of potential contraindications, risk factors, and drug-drug interactions relevant to MDMA-assisted...

Psilocybin-assisted therapy (PAT) shows promise for treating PTSD in adults but hasn't been studied in U.S. military Veterans, who face higher symptom severity and suicide risk. This open-label pilot trial evaluated the safety and feasibility of PAT in Veterans with severe, treatment-resistant PTSD. The clinical trial was pre-registered at ClinicalTrials.gov (NCT05554094). The eligibility...

Post-traumatic stress disorder (PTSD) remains difficult to prevent after trauma, highlighting the need for early interventions that reduce the risk of chronic symptom development. This controlled study investigated the preventive potential of 3,4-methylenedioxymethamphetamine (MDMA) in a validated rat model of PTSD induced by predator scent stress (PSS). Adult male Sprague-Dawley rats (N = 175)...

Background: When administered alongside monitoring and support, psilocybin has shown promise in the treatment of multiple psychiatric conditions. However, the contribution and nature of participant support in the context of psychedelic trials are much debated. Aims: We sought to further illustrate the structure and format of the monitoring and support used in Compass Pathfinder Ltd (Compass)...

Post-traumatic stress disorder (PTSD) presents a major public health problem for which currently available treatments are modestly effective. We report the findings of a randomized, double-blind, placebo-controlled, multi-site phase 3 clinical trial (NCT03537014) to test the efficacy and safety of 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy for the treatment of patients with...

OBJECTIVE Posttraumatic stress disorder (PTSD) is a chronic and disabling disorder, for which available pharmacotherapies have limited efficacy. The authors' previous proof-of-concept randomized controlled trial of single-dose intravenous ketamine infusion in individuals with PTSD showed significant and rapid PTSD symptom reduction 24 hours postinfusion. The present study is the first...

BACKGROUND: "Mindfulness-based" interventions show promise for stress reduction in general medical conditions, and initial evidence suggests that they are accepted in trauma-exposed individuals. Mindfulness-based cognitive therapy (MBCT) shows substantial efficacy for prevention of depression relapse, but it has been less studied in anxiety disorders. This study investigated the feasibility,...

Psychiatrists and psychotherapists in the US (1970s to 1985) and Switzerland (1988–1993) used MDMA legally as a prescription drug, to enhance the effectiveness of psychotherapy. Early reports suggest that it is useful in treating trauma-related disorders. Recently, the first completed pilot study of MDMA-assisted psychotherapy for PTSD yielded encouraging results. Designed to test the safety...
