Ketamine holds promise for the treatment of post-traumatic stress disorder (PTSD), but challenges remain in delivery and sustained effects. This controlled study evaluates a novel intranasal formulation, employing AmyloLipid nanovesicles (ALN) to enhance ketamine’s therapeutic efficacy in a predator-scent stress (PSS) rat model of PTSD. A total of 130 rats underwent PSS or sham-PSS exposure,...
Abstract Post-traumatic stress disorder (PTSD) is a debilitating condition that affects millions of veterans. A recent observational study in 30 veterans showed that a single dose of the atypical psychedelic ibogaine can be highly effective at treating PTSD up to twelve months later. Although a prior study demonstrated that ibogaine transiently alters electroencephalography (EEG) power in...
Background: Complex post-traumatic stress disorder (C-PTSD) is a trauma-related condition characterized by pervasive disturbances in affect regulation, self-concept, and interpersonal functioning that extend beyond the symptom profile of post-traumatic stress disorder (PTSD). While neurobiological studies have implicated limbic, salience, and prefrontal systems in C-PTSD, mechanistic accounts...
PURPOSE/BACKGROUND: Chronic insomnia causes malaise and is associated with depression, irritability, cognitive impairment, impaired alertness, and substance abuse. Individuals with posttraumatic stress disorder (PTSD) often have both inadequate and fragmented sleep, putting them at elevated risk for these consequences. Sleep abnormalities in patients with PTSD include frequent trauma-related...
There is growing interest in novel approaches to treating posttraumatic stress disorder (PTSD), including the use of psychedelic substances combined with psychotherapy, often referred to as psychedelic-assisted therapy, to better meet the needs of patients who do not prefer or respond to traditional evidence-based treatments. Among these treatments, 3,4-methylenedioxymethamphetamine...
Posttraumatic stress disorder (PTSD) is a chronic and disabling condition and identifying beneficial therapies is timely and important. We aimed to estimate the efficacy of 3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT) compared with control on clinical and functional outcomes in PTSD. A PRISMA-compliant search (PROSPEROCRD42022353261) up to August 14, 2025, covered nine databases...
MDMA and ketamine IV currently have the greatest support in the literature for efficacy in PTSD. Studies suggest treatment with these agents under supervision may lead to improvements in PTSD symptoms, with the medications being generally well tolerated. However, caution should be used when interpreting study results due to limitations such as treatment expectancy effect and the potential for...
In psychiatry, the term flashback is widely recognized in relation to post-traumatic stress disorder (PTSD) as well as in the characterization of post-psychedelic experiences. Although it is now most commonly associated with PTSD, the term was originally introduced in the context of psychedelics. While it broadly denotes specific forms of re-experiencing in both fields, its precise meaning...
Fear and anxiety perform essential protective roles, yet when they become dysregulated, they can trap trauma survivors in persistent hypervigilance and distress. Post-traumatic stress disorder (PTSD) manifests as intrusive memories, avoidance, and heightened arousal long after the precipitating event. Although current pharmacotherapies - including selective serotonin reuptake inhibitors,...
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...
Current models of post-traumatic stress disorder (PTSD) predominantly focus on emotional dysregulation, avoidance behaviors, and intrusive symptoms, with limited attention to disturbances in bodily self-consciousness. These frameworks do not fully account for how trauma may disrupt the integration of interoceptive and exteroceptive signals underlying the sense of embodied self. Building on...
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...
S elective S erotonin R euptake I nhibitors (SSRIs) and two psychedelics, Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine), and MDMA (3,4-Methylenedioxymethamphetamine) act on serotonergic-related neural circuits and function as serotonin modulators. All three molecules are either currently used or proposed as novel therapeutic modalities to treat P ost- T raumatic S tress D isorder (PTSD)....
MDMA-assisted psychotherapy has emerged as a promising treatment for post-traumatic stress disorder (PTSD), particularly in individuals unresponsive to conventional interventions such as SSRIs and trauma-focused cognitive behavioral therapy. As recent clinical trials report durable symptom remission, ongoing debate surrounds the mechanisms underlying its therapeutic effects. This review...
Sleep paralysis is a distressing parasomnia marked by temporary immobility during sleep–wake transitions, often accompanied by intense fear and hallucinatory experiences. While traditionally explained through neurophysiological mechanisms, this contemporary review highlights the significant role of psychological factors in shaping both the onset and experience of sleep paralysis episodes....
Aim: Despite being one of the most disabling symptoms of post‐traumatic stress disorder (PTSD)—disrupting sleep continuity, reinforcing hyperarousal, and worsening psychiatric comorbidity—the physiological signature of Trauma‐related nightmares (TRNs) under naturalistic sleep conditions remains poorly characterized. Methods: We used home‐based, multi‐sensor devices from the SOMMEPT cohort to...
Post-traumatic stress disorder (PTSD) represents one of the most debilitating psychiatric conditions. Posttraumatic stress disorder is frequently accompanied by sleep disturbances, including insomnia and trauma-related nightmares, affecting up to 90% of individuals with this condition. This literature review examines the bidirectional relationship between sleep disturbances and PTSD symptoms,...
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...
Recent research has highlighted the potential of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for the treatment of post-traumatic stress disorder and other trauma-related psychiatric conditions. However, less is known about the effects of MDMA use on psychological well-being in populations with trauma histories outside of clinical contexts. In the present study, we assessed...
Background/Objectives: Traumatic experiences may lead to both negative and positive outcomes. Positive psychological changes following trauma are commonly referred to as posttraumatic growth (PTG). The present study aims to examine factors associated with posttraumatic growth among Syrian refugees who have been living in Turkey for an extended period. Methods: This cross-sectional study...
