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...

Post-traumatic stress disorder places patients at risk for emergence agitation following surgical procedures under general anaesthesia. Gynaecological procedures, sphincteroplasty, and surgical interventions involving the pelvic floor can involve vulnerable patient positioning in theatre, with inserted catheters and sensory stimulation. Such interventions could contribute to postoperative...

Background: The potential safety and efficacy of the psychedelic 3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT) for post-traumatic stress disorder (PTSD) has been researched in phase 2 and phase 3 clinical trials. We examined the occurrence and role of mystical experiences in MDMA-AT. Methods: Data were sourced from two phase 2 randomized trials of MDMA-AT for chronic PTSD, in...

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)...

Posttraumatic stress disorder (PTSD) is characterized by difficulties in emotion regulation and altered recruitment of prefrontal control systems during cognitive reappraisal. Cannabinoid signaling has been implicated in stress and affect regulation, yet dose-dependent effects of acute delta-9-tetrahydrocannabinol (THC) on the neural mechanisms supporting reappraisal in PTSD remain unclear. In...

Background. Post-Traumatic Stress Disorder (PTSD) is an important public health challenge typically treated with trauma-focused psychotherapy and Selective Serotonin Reuptake Inhibitors (SSRIs). However, high rates of residual symptoms associated with these standard treatments have led to a renewed interest in psychedelic-assisted therapies. Aim. This review attempts to examine emerging...

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)...
