Impact of psilocybin on cognitive function: A systematic review.

Psilocybin is a classic psychedelic with demonstrated preliminary clinical efficacy in a range of psychiatric disorders. Evaluating the impact of psilocybin on cognitive function is essential to unravel its potential benefits and risks. In this systematic review, we assessed psilocybin's effect on cognitive function through a comprehensive search of electronic databases from inception to January 2024, identifying 20 articles involving 2,959 participants.

MDMA for treatment of PTSD and neurorehabilitation in military populations.

Background: Neurorehabilitation in military populations is complicated by higher rates of PTSD and unique characteristics of military institutions. These factors can adversely impact the patient-therapist therapeutic alliance and engagement with the rehabilitation process leading to poorer outcomes. MDMA is a non-classical psychedelic with pro-social and fear regulating properties.

Expert opinions on implementation of MDMA-assisted therapy in Europe: critical appraisal towards training, clinical practice, and regulation.

The positive results of MDMA from Phase 2 and 3 clinical trials in MDMA-assisted therapy (MDMA-AT) for the treatment of post-traumatic stress disorder (PTSD) call for a critical evaluation of its regulatory status within the European mental healthcare system. This is driven by the recent submission of MDMA-AT for FDA approval in the United States. Unless coordinated efforts in the European regulatory landscape start, there may be potential divergences in national regulatory strategies.

Symptoms of Posttraumatic Stress Disorder Among Japanese Peacekeepers Deployed in South Sudan.

Importance: Peacekeepers in United Nations missions experience potentially traumatic events, resulting in increased risk for posttraumatic stress disorder (PTSD). Understanding the course and risk factors of PTSD symptom severity is crucial to ensure personnel safety.

Objective: To investigate the incidence of PTSD, symptom severity trajectories, and potential risk factors associated with adverse trajectories among Japanese peacekeepers deployed in South Sudan.

Trauma care in crisis: war trauma and mental health funding.

Israel is currently under a state of continued unrest and state of war. There has been an influx of financial aid to treat the mental health fallout both from within Israel and abroad. Despite increased research into resilience, treatment and wide-scale interventions, there is a concern that this is not significantly influencing mental health aid allocation.

Alterations in brain network connectivity and subjective experience induced by psychedelics: a scoping review.

Intense interest surrounds current research on psychedelics, particularly regarding their potential in treating mental health disorders. Various studies suggest a link between the subjective effects produced by psychedelics and their therapeutic efficacy. Neuroimaging evidence indicates an association of changes in brain functional connectivity with the subjective effects of psychedelics.

Blood-based DNA methylation and exposure risk scores predict PTSD with high accuracy in military and civilian cohorts.

Background: Incorporating genomic data into risk prediction has become an increasingly useful approach for rapid identification of individuals most at risk for complex disorders such as PTSD. Our goal was to develop and validate Methylation Risk Scores (MRS) using machine learning to distinguish individuals who have PTSD from those who do not.

Methods: Elastic Net was used to develop three risk score models using a discovery dataset (n = 1226; 314 cases, 912 controls) comprised of 5 diverse cohorts with available blood-derived DNA methylation (DNAm) measured on the Illumina Epic BeadChip.

Patient perspectives and experiences with psilocybin treatment for treatment-resistant depression: a qualitative study.

Psilocybin is the most researched classic psychedelic for Treatment-Resistant Depression (TRD). While optimizing set and setting are considered essential for efficacy and safety, patient perspectives on these aspects have rarely been investigated. To address this knowledge gap, the current paper explored the experiences of 11 TRD patients (8 women, 3 men) participating in a double-blind randomized clinical trial with a single session of oral (1, 10 or 25 mg) psilocybin treatment.

Differentiating social environments of high-risk professionals and specialised nurses: a qualitative empirical study on social embeddedness.

High-risk professionals and specialised nurses in hospitals are frequently exposed to potentially traumatic events. Psychotrauma researchers have extensively studied personal risk factors of traumatisation among high-risk professionals, but it is hard to understand psychological functioning when professionals are decontextualised from their social environment. Generally, it has been well documented that to reduce the risk of posttraumatic stress disorder (PTSD) or other mental health problems related to traumatisation, it is essential to be embedded in a supportive social environment.

Psychometric evaluation of the Dutch International Trauma Questionnaire for the 11th revision of the International Classification of Diseases posttraumatic stress disorder and complex posttraumatic stress disorder.

Background: The International Trauma Questionnaire (ITQ) is a recent self-report measure to assess the severity and probable posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as defined by the 11th revision of the . Few studies have examined the psychometric properties of full and short ITQ versions in depth. Therefore, we aimed to evaluate the psychometric properties of the Dutch-translated 28-item ITQ and the 12-item version.

3MDR treatment in an adolescent with PTSD: a case report.

As Posttraumatic stress disorder (PTSD) in adolescents significantly impacts their well-being, effective treatment is of great importance. Little is known, however, about the novel, multi-modal virtual reality supported, exposure-based psychotherapeutic interventions such as 3MDR in this population. To describe the 3MDR treatment of an adolescent with PTSD who did not respond to previous exposure-based PTSD interventions.

PTSD Symptom dynamics after the great east japan earthquake: mapping the temporal structure using Dynamic Time Warping.

After the Great East Japan Earthquake [GEJE], approximately 70,000 Japan Ground Self Defense Force [JGSDF] personnel were deployed, risking Post-Traumatic Stress Disorder [PTSD]. The network approach to psychopathology suggests that symptoms may cause and exacerbate each other, resulting in the emergence and maintenance of disorders, including PTSD. It is therefore important to further explore the temporal interplay between symptoms.

Perceived key change phenomena of MDMA-assisted psychotherapy for the treatment of severe PTSD: an interpretative phenomenological analysis of clinical integration sessions.

Post-traumatic stress disorder (PTSD) is a prevalent psychiatric condition that significantly impacts daily functioning in patients but lacks adequate treatment options. 3,4-methylenedioxymethamphetamine (MDMA) as an adjunct to psychotherapy for the treatment of PTSD has been studied increasingly for the last two decades and has shown promising results through quantitative data. However, few qualitative studies have been conducted to investigate patients' experiences who participate in these trials.

Phenomenology and therapeutic potential of patient experiences during oral esketamine treatment for treatment-resistant depression: an interpretative phenomenological study.

Background: Ketamine and its enantiomers are widely researched and increasingly used to treat mental disorders, especially treatment-resistant depression. The phenomenology of ketamine-induced experiences and their relation to its psychotherapeutic potential have not yet been systematically investigated.

Aims: To describe the phenomenology of patient experiences during oral esketamine treatment for treatment-resistant depression (TRD) and to explore the potential therapeutic relevance of these experiences.

Treatment of Posttraumatic Stress Disorder: A State-of-the-art Review.

This narrative state-of-the-art review paper describes the progress in the understanding and treatment of Posttraumatic Stress Disorder (PTSD). Over the last four decades, the scientific landscape has matured, with many interdisciplinary contributions to understanding its diagnosis, etiology, and epidemiology. Advances in genetics, neurobiology, stress pathophysiology, and brain imaging have made it apparent that chronic PTSD is a systemic disorder with high allostatic load.
