Post-traumatic stress disorder (PTSD) and associated trauma and stressor-related disorders are common and debilitating, presenting significant treatment challenges due to their complex interplay of biological, cognitive, affective, somatic and social factors. Current treatments, while advancing and effective, yield limited efficacy for many individuals, underscoring the need for novel...
We previously completed a double-blind randomised crossover study assessing intramuscular ketamine for treatment-resistant depression (TR-D), post-traumatic stress disorder (TR-PTSD) and obsessive-compulsive disorder (TR-OCD). Here, we report an extension study to explore the ongoing benefits and tolerability of maintenance oral ketamine. All participants from the original study were eligible...
The incidence of psychiatric disorders, such as post-traumatic stress disorder (PTSD), anxiety, and depression, has been steadily increasing, while current treatment approaches remain limited in efficacy. As a result, there is an urgent need to explore more effective therapeutic interventions. In recent years, MDMA (3,4- methylenedioxymethamphetamine)-assisted therapy (MDMA-AT) has emerged as a...

One of 3 patients in the ICU receiving mechanical ventilation demonstrates posttraumatic stress disorder (PTSD). A single dose of ketamine has been shown to reduce PTSD symptoms in outpatients with chronic PTSD, but its long-term effect is unknown in patients who are critically ill and mechanically ventilated. Is ketamine, when used for induction of anesthesia before emergency tracheal...
We measured the safety and efficacy of a treatment protocol that includes Orgasmic Meditation (OM), a structured attention training practice conducted between two people who follow a predefined set of detailed instructions. The practice involves one person gently stroking the clitoris of the other person for 15 minutes while both place their attention on the point of contact and notice what...
Existing studies predominantly focus on the molecular and neurobiological mechanisms underlying Ketamine's acute treatment effects on post-traumatic stress disorder (PTSD). This emphasis has largely overlooked its sustained therapeutic effects, which hold significant potential for the development of targeted interventions. This systematic review examines the pharmacokinetic and pharmacodynamic...

Ketamine and esketamine are increasingly used to manage treatment-resistant depression and have also been shown to reduce symptoms of posttraumatic stress disorder (PTSD). Little is known about how common comorbidities in the veteran population, such as traumatic brain injury (TBI) or obstructive sleep apnea (OSA), may influence ketamine and esketamine treatment outcomes. In this retrospective...
Abstract Background Ketamine has emerged as a rapid-acting therapeutic option for post-traumatic stress disorder (PTSD); however, its ability to sustain long-term therapeutic outcomes remains poorly understood. Identifying molecular biomarkers predictive of a sustained response to ketamine may enhance personalised treatment strategies. This study investigates the epigenetic and transcriptomic...
Ketamine’s rapid acting symptom relief make it a promising intervention for PTSD. However, the mechanisms driving its long-term efficacy over weeks and months remain poorly understood. This study investigated the short-and long-term impacts on gene expression of a six-week subanesthetic oral ketamine trial in 23 PTSD participants (9 males, 14 females). Peripheral Blood Mononuclear Cells (PBMCs)...
Law enforcement is a high-stress profession, with officers frequently exposed to traumatic events, leading to mental health challenges such as communication anxiety, post-traumatic stress disorder (PTSD), anger management difficulties, and mood disorders. Mindfulness meditation (MM), particularly when guided through short video applications, has shown promise in addressing these issues by...
