Psilocybin increases social connectedness and has strong clinical transdiagnostic efficacy for mental illness, making it a candidate treatment to reduce maternal disconnect, anxiety, and blunted affect seen in peripartum mood disorders. However, the efficacy and safety of psilocybin in peripartum mood disorders has not been investigated. We used a social str...
Psilocybin is found in a family of mushrooms commonly known as Psilocybe. We aimed to study the antinociceptive efficacy of psilocybin using formalin-induced noxious stimuli, a model that comprises both acute and persistent pain in rats. Adult male Sprague-Dawley rats were used. Psilocybin (0.1, 0.3, and 1 mg/kg, IP) or vehicle was administered, and 6 h late...
BACKGROUND: In recent years, there has been a resurgence of scientific interest in psychedelics, including psilocybin, for their potential in treating neuropsychiatric disorders. However, the reward-related effects of psilocybin and its impact on behavior remain underexplored. AIMS: We aimed to evaluate the potential rewarding effects of high doses of psiloc...
BACKGROUND & AIMS: There are few effective treatments for methamphetamine use disorder, despite increasing global demand. Here, we assessed the safety and feasibility of outpatient psilocybin-assisted psychotherapy for methamphetamine use disorder. DESIGN: Single arm, open label pilot study. SETTING: Outpatient public stimulant treatment program at St. Vince...
High Resolution Image Download MS PowerPoint Slide Mental disorders of the global population have been evaluated statistically by decades. Psilocybin has medicinal properties with potential pharmaceutical applications for treatment of psychological disorders. This component is present naturally in mushrooms of the Psilocybe genus and is primarily responsible...
Czechia has recently approved the medical use of psilocybin, marking a pivotal shift in the country’s drug policy landscape. This development paves the way for regulated therapeutic applications of psilocybin within clinical settings, while simultaneously prompting a timely discussion on the potential uses of psychedelics beyond strictly medical contexts. Th...
Abstract Background Major Depressive Disorder (MDD) is a leading cause of disability and economic loss, with high recurrence and treatment resistance. Psilocybin-assisted therapy (PAT) shows promise in reducing depressive symptoms, but long-term effects are unknown. We aimed to determine the long-term safety and efficacy of PAT for MDD over a five-year follo...
Psychedelic substances have experienced a resurgence of clinical interest in recent years, particularly for their promising effects in the treatment of psychiatric disorders such as depression and anxiety. While evidence regarding their role in chronic pain management remains limited, emerging studies suggest potential therapeutic benefits. This case report ...
Introduction: Recently, there has been a significant increase in interest in the use of psychedelics for various psychiatric conditions. Psilocybin is receiving particular attention as a psychoactive substance with significant therapeutic potential. Recent research focuses on its possible benefits in the treatment of major depressive disorders (MDD) and anor...
OBJECTIVE: Due to the boom in the use of certain psychedelics in different neuropsychiatric conditions, the objective was to synthesize the available information on the use of psilocybin (a psychedelic) in the population with autism spectrum disorder (ASD; a developmental neuropsychiatric condition). METHODS: Scoping review. Question framework: Population: p...
Background: Depressive disorders are a major global health challenge, with many individuals unresponsive to existing treatments. Novel psychedelic therapies show promise but require further research. Objectives: This study aimed to evaluate the feasibility, safety and effectiveness of psilocybin with psychotherapeutic support for treatment-resistant depressi...
Objectives: Given the increasing use of psilocybin-containing substances across a variety of use settings, understanding the potential risks is imperative for informing public health policy, health care providers, and consumers. Poison centers (PCs) receive calls following exposures to potential toxins to support the detection, prevention, and treatment of t...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition for which there are few efficacious treatments. Psilocybin is being studied for use in treatment-resistant depression but has not yet been investigated in PTSD. Aims: The trial’s primary outcome was to investigate the safety and tolerability of single-dose psilocybin in participant...
BACKGROUND AND AIMS: Drug discrimination procedures have made important contributions to the pre-clinical investigation of psychedelic drugs, such as psilocybin, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). One of the most important being to highlight the critical role of central 5-HT2A rece...
We quantify cellular- and circuit-resolution neural network dynamics following therapeutically relevant doses of the psychedelic psilocybin. Using chronically implanted Neuropixels probes, we recorded local field potentials (LFP) alongside action potentials from hundreds of neurons spanning infralimbic, prelimbic and cingulate subregions of the medial prefro...
Psilocybin, a serotonergic compound that produces psychedelic effects primarily through activation of the 5-HT2A receptor, has shown promise in treating neuropsychiatric conditions, including obsessive-compulsive disorder (OCD). However, the effects of chronic psilocybin administration on gut function, microbiota, and behavioural phenotypes remain understudi...
Through its widespread reciprocal connections with the cerebral cortex, the claustrum is implicated in sleep and waking cortical network states. Yet, basic knowledge of neuromodulation in this structure is lacking. The claustrum is richly innervated by serotonergic fibers, expresses serotonin receptors, and is suggested to play a role in the ability of psilo...
IMPORTANCE: Psilocybin-assisted psychotherapy may offer a novel approach to treating depression, anxiety, and existential distress in individuals with life threatening illnesses, where current treatments show limited efficacy. OBJECTIVE: To evaluate the efficacy and safety of psilocybin-assisted psychotherapy versus active placebo and psychotherapy in adults...
Treatment resistant depression (TRD) is frequently encountered in clinical practice. The lack of response of the condition to conventional medications and augmentation strategies has spawned the search for novel treatment approaches. Psychedelic medications used in conjunction with intensive psychotherapy, so-called psychedelic-assisted psychotherapy (PAP), ...
