Psychedelic drugs such as LSD and psilocin were once relegated to the fringes of medical research because of their association with counterculture movements and a perceived concern about harm through recreational use, and their consequent legal prohibition in the early 1970s. However, these drugs are now experiencing a renaissance in the field of psychiatry ...
Abstract Introduction Psychedelic use and interest in its therapeutic potential are rapidly increasing; yet its relationship with insomnia remains poorly understood. This study aims to estimate differences in insomnia severity by type of psychedelic consumed among a cohort of 18-to-35-year olds. Methods Data are from the Herbal Heart Study - Sleep Ancillary ...
Psychedelic-assisted therapy (PAT) has demonstrated substantial efficacy across a range of mental disorders. However, heterogeneity between patients confers differential responsiveness. This systematic review aims to explore factors which may predict therapeutic responses to PAT. A systematic search was performed from inception through to March 2024 and stud...
BackgroundWild mushroom foraging is common in the United States. Poisoning usually results from misidentification, though some "edible" mushrooms can also cause toxicity. Armillaria ("honey mushrooms") are widely foraged and generally considered edible, yet sporadic gastrointestinal illness has been reported. Their clinical effects remain poorly described. P...
The goal of this clinical trial is to systematically categorize potential prohedonic effects of psilocybin in patients with anhedonia in depression. The main questions it aims to answer are: Primary Objectives 1. Systematically categorize prohedonic effects (antianhedonic effects in patients with anhedonia in depression, increase in well-being in all partici...
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 ...
Production of the psychoactive compound psilocybin is a defining feature of the genus Psilocybe, commonly referred to as “psychedelic mushrooms”. However, Psilocybe fuscofulva is a striking exception within Psilocybe sensu stricto as it lacks the stereotypical blue bruising characteristic of the genus, and psilocybin has not been detected in the species.To i...
Humphry Osmond coined the term ‘psychedelic’ in 1956, conjoining ‘psyche’ for ‘soul’ and ‘delic’ from ‘dêlos’ for ‘to manifest’ or ‘illuminate.’ Soul-illumination is an adjective that describes a psychological state or process. However, Osmond’s intention was to use the adjective to name- not just a state- but a category of drug that can induce the subjectiv...
Psychedelic-assisted interventions are emerging as potential treatments for substance use disorders, including alcohol use disorder (AUD). While recent randomized controlled trials suggest efficacy for certain psychedelics and related compounds in treating AUD, the impact of naturalistic psychedelic use on problematic alcohol consumption remains underexplore...
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 ...
Conventional antidepressants show moderate efficacy in treating major depressive disorder. Psychedelic-assisted therapy holds promise, yet individual responses vary, underscoring the need for predictive tools to guide treatment selection. Here, we present graphTRIP (graph-based Treatment Response Interpretability and Prediction) - a geometric deep learning a...
Abstract Music is integral to Psilocybin-assisted psychotherapy (PAP), believed to enhance therapeutic outcomes by structuring experiences and facilitating emotional expression. However, the effects of conducting PAP without music are underexplored. This study examines the experiences of two breast cancer patients undergoing psilocybin therapy under Canada's...
Serotonin 5-HT2A receptors were one of the first serotonin receptors to be pharmacologically characterized. In mammals, they are expressed throughout the body in nearly every cell and tissue type, with the highest density in cortical layer V of the brain. They are involved in several aspects of normal physiological processes and behaviors and have been impli...
Few population-based studies have examined associations between psychedelic use and mental health outcomes. This work describes characteristics of exclusive psychedelic mushroom use (referred to as PM use), PMs in combination with other psychedelic substances (multi-psychedelic or MP) use, and non-psychedelic use and explores mental health ratings in non-cli...
Abstract Effective interventions for neuropsychiatric disorders may work by rebalancing the brain’s functional hierarchical organization. Here we directly investigated the effects of two different serotonergic pharmacological interventions on functional brain hierarchy in major depressive disorder in a two-arm double-blind phase II randomized controlled tria...
Aspects of the acute experience induced by the serotonergic psychedelic psilocybin predict symptomatic relief in multiple psychiatric disorders and improved well-being in healthy participants, but whether these therapeutic effects are immediate or are based on memories of the experience is unclear. To examine this, we co-administered psilocybin (25 mg) with ...
e22518 Background: Classic psychedelics (Peyote, Psilocybin, Mescaline, and LSD) are re-emerging in the oncology toolbox. Peyote is the oldest known psychedelic, yet underexplored in clinical research. Preclinical studies suggest its extract stimulates lymphocyte proliferation, kills tumor cells, and may regulate sleep. This study aims to estimate the preval...
Psilocybin, a naturally occurring, tryptamine alkaloid prodrug, is currently being investigated for the treatment of a range of psychiatric disorders. Preclinical reports suggest that the biological effects of psilocybin-containing mushroom extract or "full spectrum" (psychedelic) mushroom extract (PME), may differ from those of chemically synthesized psiloc...
