Dissociation, an altered state of consciousness in which individuals feel detached from their body, environment, and sense of self, is a common feature of posttraumatic stress disorder (PTSD). Despite its significance, the neurocognitive processes underlying dissociation remain poorly understood, potentially limiting diagnostic precision and treatment efficacy in PTSD. To address this gap, we...
Posttraumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD) often co-occur, worsening outcomes, relapse rates, and treatment response. Ketamine produces rapid and sustained PTSD symptom reduction and reduces AUD relapse. Prazosin effectively treats PTSD-related nightmares and may reduce alcohol consumption in individuals with heightened autonomic reactivity. The dual complementary...
Abstract Background: Post-traumatic stress disorder (PTSD) is a common mental health condition affecting approximately 3-6% of the U.S. adult population annually, and is characterized by intrusive symptoms, avoidance, negative cognitive and mood alterations, and hyperarousal following trauma exposure. Ketamine shows promise as a treatment for PTSD in preliminary trials, though real-world...
Firefighters are exposed to a disproportionately high number of traumatic incidents and, thus, display elevated rates of trauma-related mental health disorders, with the reported average PTSD prevalence being 7.3% in firefighters vs 1.3-3.5% in the general populationOftentimes, conventional treatments demonstrate limited efficacy. Ketamine-assisted therapy (KAT) has recently arisen with...
Ketamine, a nonselective NMDA-receptor antagonist, is an emerging therapeutic for treatment-resistant depression and could also be a promising treatment for anxiety and post-traumatic stress disorders. However, preclinical studies in these areas lack methodological standardization, limiting clinical translatability. This review evaluates ketamine's anxiolytic potential in rodents by examining...

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...
