Psilocybin is a molecule with significant potential for the treatment of mental disorders such as depression, anxiety, post-traumatic stress disorder, and substance abuse. In this study, it was explored the extraction of psilocybin from Psilocybe cubensis mushrooms using a factorial design approach, along with the physicochemical and phytochemical characterization of the extracted material,...
Psilocybe cubensis mushrooms are typically not consumed for their nutritional value. The main reason people ingest these mushrooms is for their psychoactive effects. Recently, there has been growing interest in the potential therapeutic applications of psilocybin-containing mushrooms in a range of psychiatric conditions, including depression, anxiety disorders, obsessive-compulsive disorder,...
Psychedelic-assisted therapies have re-emerged as a subject of increasing scientific and clinical interest in psychiatry, particularly in the context of persistent treatment gaps for conditions such as treatment-resistant depression, post-traumatic stress disorder, and substance use disorders. Compounds, including psilocybin and 3,4-methylenedioxymethamphetamine, are being evaluated in...
Classical serotonergic psychedelics (e.g., LSD, psilocybin, DMT) alter perception and neuroplasticity primarily via 5-HT2A receptor activation and downstream Ca2+-dependent signaling cascades. Here we propose a speculative yet falsifiable pharmacological hypothesis that these drug-induced biochemical cascades might interface with quantum-mechanical processes in the brain. We focus on nuclear...
The Swiss Federal Office of Public Health provides case-by-case exemptions allowing physicians to provide psychedelic-assisted therapy (PAT) using psilocybin, lysergic acid diethylamide (LSD), or 3,4-methylenedioxy-N-methamphetamine (MDMA). The study provided an overview of PAT as currently provided in Switzerland under the regulatory framework of the Federal Office of Public Health (FOPH)....
Advanced Alzheimer's disease (AD) is generally regarded as a stage of irreversible functional decline. Psilocybin is known to transiently alter large-scale brain network dynamics and to induce plasticity-related mechanisms in preclinical models, yet clinical data in advanced dementia remain lacking. We report the case of an octogenarian Japanese-American woman with a 10-year history of...
Psychedelic-assisted psychotherapy (PAP) is emerging as a novel intervention for major psychiatric disorders, most notably major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). While psychotherapy is widely regarded as a core element of PAP its precise role remains poorly defined. This narrative review traces the development of PAP within contemporary Western psychiatry,...
Les psychédéliques classiques sont des substances connaissant un regain d’intérêt dans la recherche depuis le début du 21e siècle. En contexte clinique et naturaliste (récréatif ou à des fins de rituel), plusieurs études ont démontré que l’utilisation de ces substances pouvait contribuer à la réduction de la consommation d’alcool problématique. La présente étude vise à mieux comprendre les...
BACKGROUND: Psychedelics such as 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin are showing promising results in clinical trials for the treatment of mental health disorders, including post-traumatic stress disorder, addiction, and treatment-resistant depression. US Food and Drug Administration approval may be on the horizon. Yet, little is known about how these treatments will move...
The reported mixed findings suggest that the opioid system may exert a partial mediating effect of ketamine in TRD. However, given the inconsistent attenuation of ketamine's antidepressant effects by opioid receptor antagonists, the opioid system likely functions as a context-dependent modulator rather than a primary mediator, particularly at standard antidepressant doses.
