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...
Psychedelics, derived from the Greek words "psyche" (soul) and "deloun" (revealing), are substances historically and currently considered "soul-revealing". Also termed hallucinogens due to their impact on sensory perception, they are further categorized into hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and mescaline; entactogens or em...
Abstract Background Psychedelics have long been explored as potential treatments for mental illnesses. Since the mid-20th century, clinical trials of psychedelics such as LSD for depression and anxiety in terminally ill patients have been conducted. In the 21st century, revived and accelerated efforts to promote the proper use of psychedelics in the medical ...
Abstract Background Obsessive-compulsive disorder (OCD) is associated with significant personal suffering and functional impairment. At least a third of OCD patients do not respond to conventional treatments. There is a substantial anecdotal literature suggesting that psychedelic agents, specifically psilocybin and psilocybin-containing psychedelic mushroom ...
Accumulating evidence suggests that psilocybin can produce rapid and sustained clinical benefits when administered in conjunction with psychological support. Though non-pharmacological procedures are considered integral, the field lacks therapeutic guidelines and little is known about current practices. This systematic review sought to provide a comprehensiv...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a common and disabling condition. A large proportion of patients fail to respond to first-line treatment with serotonin reuptake inhibitors either selective serotonin reuptake inhibitors (SSRIs) or clomipramine. Preliminary evidence suggests psilocybin, a serotonin receptor agonist, might be efficacious. We ...
There is growing interest in exploring the therapeutic potential and mechanisms of action of psilocybin on stress-related neuropsychiatric disorders, including depression, generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), addiction, and disordered eating. Despite promising progressions in preclini...
Microdosing, the repeated use of psychedelic substances at low doses, is growing in popularity among recreational consumers. While this practice is associated with many benefits to mood, well-being and health, research in this area is in its early stages and predominantly centered on human applications. In this narrative review, we synthesize the findings fr...
Psychedelics, such as psilocybin and lysergic acid diethylamide, modulate neuroplasticity and brain connectivity via 5-HT2A receptors. Their efficacy has been demonstrated in depression and anxiety, where they are particularly interesting because of their rapid and long-lasting effect. They could also be beneficial for addictions, post-traumatic stress, and ...
Psychiatric disorders are marked by habitual patterns of thought, emotion, and behavior, and many mental health disorders are resistant to standard treatments (1)(2)(3)(4). For example, symptoms of major depressive disorder include ruminative negative thoughts, pervasive sadness, and lack of goaldirected behavior (5)(6)(7). Similarly, many anxiety and trauma...
Clinical trials using full doses of psychedelics have provided preliminary evidence supporting their safety and efficacy in treating a variety of physical and psychological conditions. Anecdotal reports indicate that even very small amounts of these substances may provide therapeutic benefits, though robust clinical studies are still needed. This chapter rev...
In recent years, there has been a significant surge of interest in psychedelic research. These studies encompass both neuroscience and their potential clinical applications. This phenomenon, often referred to as the "Psychedelic Renaissance", includes studies on compounds such as psilocybin, MDMA, DMT, and LSD used for the treatment of depression, post-traum...
Abstract Background and Aims Networks of so-called underground, or illegal, psilocybin mushroom practitioners are popularly known to exist, though few systematic investigations of their practices have been conducted. We sought to uncover the experiences of a hidden community of psilocybin practitioners in order to inform scientific and policy dialogues about...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a complex condition marked by persistent distressing thoughts and repetitive behaviours. Despite its prevalence, the mechanisms behind OCD remain elusive, and current treatments are limited. This protocol outlines an investigative study for individuals with OCD, exploring the potential of psilocybin to impro...
Psilocybin-assisted therapies (PAT) have been used to treat several issues including obsessive-compulsive disorder (OCD), major depressive disorder (MDD), posttraumatic stress disorder (PTSD), smoking addiction, and anxiety (Grob et al., 2011; Johnson et al., 2014; Kisely et a., 2022; Moreno et al., 2006). If more positive benefits of psilocybin are discover...
ObjectiveThe authors critically examine the evidence base for psilocybin administered with psychological support/therapy (PST) in the treatment of psychiatric disorders and offer practical recommendations to guide future research endeavors.MethodsPubMed was searched for English-language articles from January 1998 to November 2023, using the search term "psil...
The revival of psilocybin in psychopharmacological research heralds a potential paradigm shift for treating mood and anxiety disorders, and other psychiatric conditions beyond the psychotic spectrum. This critical review evaluates current evidence on psilocybin's efficacy, juxtaposing potential benefits with the practical aspects of psychedelic-assisted psyc...
Psychedelics are emerging as potential treatments for a range of mental health conditions, including anxiety and depression, treatment-resistant depression, and substance use disorders. Recent studies have also suggested that the psychedelic psilocybin may be able to treat obsessive-compulsive disorder (OCD). Since the 1960s, case studies have reported impro...
