Post-traumatic stress disorder (PTSD) exhibits extensive clinical and biological variability, making treatment challenging. The Consortium to Alleviate PTSD (CAP)-ketamine trial, the largest randomized study of ketamine for PTSD, found no overall benefit of ketamine over placebo, underscoring the necessity to identify responsive subgroups. Using pre-treatment blood DNA methylation profiles and...
Arginine vasopressin (AVP) modulates stress responsivity and social-affective behaviors, but its role in mood and trauma-related disorders remains poorly defined due to challenges in peripheral measurement. This study used copeptin, a stable, reliable, and well-validated surrogate marker of AVP secretion, to assess vasopressinergic function in a transdiagnostic sample of individuals...
Purpose A systematic review was conducted to synthesize the efficacy, safety, and tolerability of psychedelics including ketamine, MDMA, ayahuasca, LSD, DMT, ibogaine, and psilocybin in the treatment of PTSD. Recent Findings Among 5,155 studies identified, 42 studies met criteria and were included in our systematic review. Ketamine consistently produced rapid symptom improvement that attenuated...
ABSTRACT Introduction Posttraumatic stress disorder (PTSD) is a mental disorder resulting from exposure to traumatic events. Evidence suggests that ketamine may be efficacious in treating PTSD, however, ketamine's mechanisms in treating PTSD remain unclear. Herein, this review aims to evaluate the clinical outcomes of ketamine treatment in persons with PTSD and investigate the possible...
The aim of the study was to evaluate the practice of using ketamine-assisted psychotherapy (KAT) in accordance with international clinical guidelines at the State Institution "Center for Mental Health and Veterans' Rehabilitation 'Lisova Polyana' of the Ministry of Health of Ukraine" (Ukraine).Adapting the international clinical guidelines on ketamine therapy for treatmentresistant depression...
Post-traumatic stress disorder (PTSD) is a chronic psychological disorder that is induced by traumatic events. The pathophysiological mechanism of PTSD involves complex neurobiological processes. However, the underlying mechanism is not clear, leading to lack of effective therapeutic interventions. Mice were exposed to the electric foot shocks using the contextual fear memory paradigm. A...
Background: Posttraumatic stress disorder (PTSD) is associated with maladaptive memory reconsolidation and overgeneralized fear responses. EMDR therapy promotes trauma reprocessing by activating the brain's intrinsic memory reconsolidation mechanism, facilitating memory updating, and abandoning outdated emotional schemas. Ketamine may also facilitate adaptive updating of traumatic memory due to...

Major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are debilitating psychiatric conditions associated with poor health outcomes similarly observed in non-pathological aging. Ketamine is a dissociative anesthetic and NMDA receptor antagonist with demonstrated rapid reduction in symptoms associated with Treatment Resistant Depression (TRD) and PTSD. Ketamine's effects on...
We provide preliminary support for the efficacy and tolerability of i.m. ketamine in a community sample of individuals with PTSD. Further work is required to establish the optimal dosing regimen and longer-term role of ketamine in treatment of PTSD, but our findings are encouraging given the well-known of treatments in this area.

Current pharmacotherapies for post-traumatic stress disorder (PTSD) are limited by delayed onset and side effects. Despite ketamine exhibiting rapid relief of the core symptoms of PTSD, its clinical efficacy varies considerably depending on the timing of drug delivery. However, the underlying mechanism remains unclear. In this study, the therapeutic effects of early (day 1) and late (day 7)...
