BACKGROUND: Posttraumatic stress disorder (PTSD) affects 3.9% of the general population. While massed cognitive processing therapy (CPT) has demonstrated efficacy in treating chronic PTSD, a substantial proportion of patients still continue to meet PTSD criteria after treatment, highlighting the need for novel therapeutic approaches. Preliminary evidence sup...
OBJECTIVE: Depression varies along a difficulty-to-treat spectrum. Patients whose illness fails to respond to at least five treatments may be considered to have severely treatment-resistant depression (TRD). The objective of this study was to document the safety and efficacy of psilocybin in patients with severe TRD. METHODS: This was a 12-week, open-label t...
OBJECTIVE: Evidence suggests that psilocybin-assisted therapy (PAT) leads to durable shifts in personality structure. However, such changes have yet to be characterized in disorders of addiction. In this secondary analysis from a randomized controlled trial, the authors examined the effect of PAT on personality dimensions in patients with alcohol use disorde...
Objective This clinical trial sought to evaluate the safety and preliminary efficacy of psilocybin and MBSR for frontline healthcare providers with symptoms of depression and burnout related to the COVID-19 pandemic. Methods This was a randomized controlled trial that enrolled physicians and nurses with frontline clinical work during the COVID-19 pandemic an...
This secondary analysis of a randomized clinical trial examines the association between treatment expectancies and the relative efficacy of psilocybin compared with escitalopram for major depressive disorder.
Importance: The psychological morbidity experienced by physicians, advanced practice practitioners (APPs), and nurses from working during the COVID-19 pandemic includes burnout, depression, and posttraumatic stress disorder (PTSD). Objective: To investigate whether psilocybin therapy could improve symptoms of depression, burnout, and PTSD in US clinicians wh...
IntroductionThere is growing interest in the use of psychedelic-assisted therapy (PAT) for major depressive disorder (MDD), including treatment-resistant depression. We used randomized controlled trial (RCT) data to compare summary estimates of change in depression ratings with PAT versus comparator treatments in MDD. We also compared response and remission ...
The purpose of this study is to assess the impact of psilocybin on cognitive inflexibility and neural plasticity in a cohort of people with obsessive-compulsive disorder (OCD). This mechanistic study will utilise a within-subjects design, administering up to 10mg of psilocybin to participants with OCD (DSM-5 criteria) on two separate instances spaced four we...
Fibromyalgia (FM) is the prototypical nociplastic pain condition, characterized by widespread pain and issues with cognition, mood, and sleep. Currently, there are limited treatment options available that effectively treat FM symptoms. Psilocybin-assisted therapy (PAT) is an emerging combined drug-therapy intervention, but no studies to-date have investigate...

Background: Due to the unsatisfactory therapeutic effects of current antidepressants, research has been launched into alternative treatment approaches, such as the administration of psychedelics. Psilocybin, a classic hallucinogen, has been shown to exert considerable positive influence on depression symptoms through its serotonergic and glutamatergic effect...
Abstract The Psilocybe cubensis SAM-dependent methyltransferase, PsiM, catalyzes the last step in the biosynthesis of psilocybin. Likely evolved from monomethylating RNA methyltransferases, PsiM acquired a key amino acid exchange in the secondary sphere of the active site, M247 N, which is responsible for its capacity to dimethylate. Two variants, PsiM N247M...
ObjectivesThe purpose of this systematic review of randomized controlled trials (RCTs) was to evaluate the effectiveness, safety, and tolerability of psilocybin in adult patients with major depressive disorder (MDD).MethodsA systematic search (up to September 14, 2023) was conducted for RCTs that examined the efficacy, safety, and tolerability of psilocybin ...
Background: Psilocybin therapy (PT) produces rapid and persistent antidepressant effects in major depressive disorder (MDD). However, the long-term effects of PT have never been compared with gold-standard treatments for MDD such as pharmacotherapy or psychotherapy alone or in combination. Methods: This is a 6-month follow-up study of a phase 2, double-blind...
BackgroundPsychedelic-assisted therapy refers to a group of therapeutic practices involving psychedelics taken under therapeutic supervision from physicians, psychologists, and others. It has been hypothesised that psychedelic-assisted therapy may reduce symptoms of anxiety, depression, and existential distress in patients facing life-threatening diseases (e...
Introduction:Psilocybin-assisted therapy (PAT) has gained traction in palliative care as a treatment for existential distress in the last decade. Patients with brain cancer have been excluded from studies, yet they stand to benefit as much as other patients with cancer-related psychological distress. Case description:In this report, we discuss the case of a ...
ObjectiveTo evaluate the comparative effectiveness and acceptability of oral monotherapy using psychedelics and escitalopram in patients with depressive symptoms, considering the potential for overestimated effectiveness due to unsuccessful blinding.DesignSystematic review and Bayesian network meta-analysis.Data sourcesMedline, Cochrane Central Register of C...
The goal of this multi-centre phase I/II open-label, single-arm study is to determine the safety, feasibility, therapeutic dose, and preliminary efficacy of psilocybin microdosing to treat psychological distress among patients with advanced illness. Forty patients will receive psilocybin drug product (1-3mg per day, Mon-Fri) for 4 weeks to be administered vi...
Psilocybin-Assisted Therapy for Severe Alcohol Use Disorder: Protocol for a Double-Blind, Randomized, Placebo-Controlled, 7-month Parallel-Group Phase II Superiority Trial A substantial proportion of patients with alcohol use disorder does not respond to available treatments, which calls for the development of new alternatives. In parallel, psilocybin-assist...
RATIONALE: Our study aimed to unravel the unknown mechanisms behind the exceptional efficacy of Psilocybin (PSI) in treating treatment-resistant depression (TRD). Focusing on Wistar-Kyoto (WKY) rats with a TRD phenotype and Wistar (WIS) rats as a normative comparison, we investigated behavioral and neuroplasticity-related responses to PSI, striving to shed l...
