Emerging evidence suggests that classical psychedelics may offer therapeutic potential for opioid use disorder (OUD) by alleviating key hallmarks such as altered reward processing and dependence. However, the mechanisms behind these effects remain unclear. Our data demonstrate that a single administration of the psychedelic psilocybin (PSI) reduces condition...
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder characterized by recurrent distressing thoughts and substantial anxiety, accompanied by repetitive behaviors or mental rituals. Individuals with OCD often have diminished quality of life, and functional impairment. The disorder cause high personal, societal and economic costs. Current availab...
Alcohol use disorder (AUD) is a highly prevalent disorder with limited therapeutic options. The central amygdala (CeA) is a critical brain region as dysregulation within the CeA and the corticotropin-releasing factor (CRF) system are associated with AUD pathology. CeA CRF1 receptors regulate alcohol drinking and have served as a therapeutic target in alcohol...
Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. P...
The past two decades have seen the reemergence of research investigating the therapeutic potential of psychedelic drugs across neuropsychiatric illnesses. One condition, alcohol use disorder (AUD), is of relevance given the broad public health implications and both limited effectiveness and attrition associated with currently available treatments. While emer...
Today’s research highlights the therapeutic potential of the hallucinogen psilocybin in the treatment of pathologies associated with mood, cognitive, and affective dysregulation. These domains of function are regulated by the serotonergic system, which can be influenced by sex hormones, like estrogen and testosterone, and psychedelic compounds including psil...
• Ketamine and psilocybin show promise in athlete recovery and pain management. • Psychedelics may enhance resilience, mood, and cognitive flexibility in sports. • Growing athlete use raises concerns for safety and anti-doping regulation. • Evidence on long-term effects with exercise remains scarce, urging research.
After many years of stigma and neglect, there is a resurgence of interest in the therapeutic use of psychedelic drugs. Anecdotal and evidence-based reports indicate psychedelics as a possible treatment for depression, anxiety, PTSD, substance abuse, and other disorders resistant to conventional medical interventions. The available data, however, are limited ...
This project will employ functional brain imaging to study the mechanism and immediate and long-term effects of psilocybin, a serotonin receptor 2A agonist, on cortical and cortico-subcortical brain networks in healthy adults. Psilocybin shows promise as a safe, transformational therapeutic across several psychiatric conditions. However, little is know about...
IntroductionBipolar disorder (BD) is a severe and persistent mental disorder characterized by recurrent mood episodes, with BD depression accounting for most of the illness burden. Although the mainstay treatment of BD consists of pharmacotherapy with mood stabilizers and atypical antipsychotics, a large proportion of patients with BD depression do not respo...
Psychedelics, particularly psilocybin, have shown therapeutic potential across several psychiatric conditions, including depression, anxiety, obsessive-compulsive disorder, and anorexia nervosa (AN). These disorders often share social deficits that may be effectively alleviated by psychedelics considering their use has been linked with emotional empathy and ...
Background and Purpose Given the increase in recreational psychedelic use and ongoing efforts to explore psychedelics as therapeutic agents for mental health disorders, there is an urgent need to understand the effect of psychedelics such as psilocybin and N,N-dimethyltryptamine (DMT) on sleep-wake states, which share a bidirectional relationship with mental...
Despite psilocybin still being a Schedule I substance in the Federal Controlled Substance Act (OHA, 2022), Oregon voters passed Measure 109 in 2020, now codified into law as ORS457A, which allowed for the opening of psilocybin clinics for eligible clients. The passing of Measure 109 allowed for an adult-use model to be created, which is different from a ther...
Psilocybin has emerged as a promising therapeutic agent for psychiatric and neurological disorders. However, its legal status varies significantly across countries, creating barriers for clinical use and research. This paper provides an international overview of the regulatory landscape governing medical psilocybin, highlighting key legal restrictions, polic...
This retrospective observational study examines the effects of psychedelic-assisted psychotherapy (PAP) with lysergic acid diethylamide (LSD) or psilocybin in patients with treatment-resistant depressive, anxiety, or addictive disorders. Data will be analyzed from patients treated at the University Hospitals of Geneva between June 2020 and April 2025 who obt...
Since the earliest LSD research, psychedelics have been claimed to enhance autobiographical memory. Revisiting and processing autobiographical memories has further been suggested to be a major component of the therapeutic action of psychedelics. However, modern psychedelic research has largely neglected autobiographical elements of psychedelic experiences, a...
Psychedelics, such as psilocybin, lysergic acid diethylamide (LSD), ketamine, and N,N-dimethyltryptamine (DMT), have captured the attention of scientists, artists, and seekers alike for their profound ability to alter consciousness and inspire creativity. The concept of "creation" encompasses multiple interpretations-ranging from generating novel ideas to fo...
The purpose for this study is to observe the real world experience of participants who are receiving psilocybin in the context of (alcoholism) Alcohol Use Disorder without intervening in the model of care. The study team will engage directly with the participants to examine the outcomes in participants who have been deemed eligible and appropriate to receive...
The potential for psilocybin, and other psychedelic drugs, to fulfil a much needed and potentially transformative class of psychiatric treatments has garnered significant attention. Consequently, there has been a great deal of interest and investment in accelerating its development and potential implementation in routine clinical practice. However, the expan...
