This is an observational study which does NOT directly administer a psychedelic substance but rather recruits participants who are already participating in another clinical trial in which they may receive a serotonergic psychedelic. The goal of this observational study is to learn how the brain's information processing changes during and following administra...
The goal of this study is to test addiction-related brain circuitry (motivation/reward and inhibition) as well as neurocognitive circuitry prior to and following low or high dose psilocybin (PEX010 from Filament). Using fMRI, brain circuits will be examined that are relevant to drug relapse as well as neurocognitive flexibility circuits in individuals with o...
Psychedelics have garnered great attention in recent years as treatments for major depressive disorder (MDD) and treatment-resistant depression because of their ability to alter consciousness and afflicted cognitive processes with lasting effects. We aimed to characterise how psychedelics are currently being investigated to treat substance use disorders (SUD...
Limit: 5000 characters. Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of certain medications such as r...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. There is interest to see if similar effects may be provided in those with obsessive compulsive disorder (OCD). The purpose of this study is to evaluate the safety, f...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of serotonin (5HT)2A receptor antagonists such as risper...
BACKGROUND AND AIMS: Australia recently down-scheduled and authorised psychedelic-assisted therapies, including psilocybin, for certain mental health conditions. Evidence is emerging for potential application in substance use disorder treatment. However, regulatory developments have outpaced implementation readiness. While service leaders and clinicians are ...
We propose a first-of-its-kind open-label clinical trial to investigate the feasibility, tolerability, and safety of administering psilocybin in autistic adults with treatment-resistant depression (TRD). In this study, 20 participants (intellectually able and fluent-speech adults) with autism and co-occurring TRD will receive around 20 hours of manualized ps...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychological support in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. The purpose of this study is to determine the role of psilocybin monitors on the effects of psilocybin therapy in adults with treatment resistant depression....
BACKGROUND AND AIMS: There has been a resurgence of interest in using psilocybin to treat various mental health conditions. Although some adults in the United States (US) are using psilocybin, little is known about the epidemiology of its use, especially for microdosing (i.e., taking a fraction of a regular dose). This study aimed to present nationally repre...
Psychedelics have emerged as potential therapeutics for substance use disorders, yet preclinical data validating their efficacy remain limited. Here, we investigated the effects of a clinically inspired dose-escalation protocol of psilocybin and ibogaine on extinction and cue-induced reinstatement in Wistar male rats following intravenous cocaine self-admini...
The goal of this pilot, exploratory, clinical trial is to investigate the effects of psilocybin on synaptic vesicular density (SVD) as measured by the positron emission tomography (PET) radiotracer, 18F-SynVesT-1, in participants with amnestic Mild Cognitive Impairment (aMCI) and healthy participants. The investigators hypothesize that SVD levels in the brai...
The goal of this clinical trial is to determine the safety and efficacy of psilocybin assisted Therapy (PAT) in individuals with comorbid Major Depressive Disorder (MDD) and Alcohol Use Disorder (AUD). The main question it aims to answer is: \- What is the feasibility and safety of administering PAT in adults with MDD-AUD by evaluating recruitment, retention...
Despite decades of neuroscience research and significant investment in addiction neuroimaging, clinical outcomes for individuals with substance use and behavioural addictions remain poor. Only 1.8% of people with substance use disorders receive effective treatment, highlighting a major disconnect between mechanistic understanding and clinical utility. This p...
Tobacco use remains a leading cause of preventable morbidity and mortality worldwide, and current smoking cessation treatments are limited by low long-term efficacy. An interplay between positive and negative reinforcement drives high relapse rates. Psychedelic compounds, particularly psilocybin, have shown promising clinical outcomes for smoking cessation, ...
BACKGROUND AND AIMS: There is an urgent unmet need for novel treatments for methamphetamine (MA) use disorder. We explored the qualitative experiences of people participating in a study of psilocybin-assisted psychotherapy (PAT) to treat MA use disorder. DESIGN AND SETTING: Qualitative study of participants enrolled in a single arm, open-label pilot study of...
Introduction Psychedelic Assisted Psychotherapy (PAP) has been legal in Switzerland since 2014 under supervised exceptional medical use with MDMA, LSD and Psilocybin with case by case authorisations delivered from the Federal Office of Public Health. In particular, since 2021, we have implemented a clinical activity at Geneva University Hospital (HUG) for tr...
Introduction Mental health disorders, including depression, anxiety, and post-traumatic stress disorder (PTSD), remain a significant global health concern, requiring novel therapeutic approaches. Psilocybin, a psychedelic compound found in certain mushrooms, has shown potential in modulating neuroplasticity, a critical process for cognitive flexibility and m...
Abstract: Background: Psychedelic-assisted therapy is increasingly being explored as potential treatment for substance use disorders (SUDs). While multiple systematic reviews and meta-analyses have examined this topic, the efficacy, methodological quality, and overlap of the existing evidence base remain unclear. Methods: We conducted an umbrella review of ...
Abstract: Aims: Symptoms of depersonalization (DP) and derealization (DR) are commonly reported during the acute effects of classic psychedelics. In some individuals, these symptoms persist, resulting in depersonalization-derealization disorder (DDD), associated with distress and help-seeking behavior. This case series seeks to underscore some of the diagnos...
