PurposeThis paper aims to examine evolving practices and discourses surrounding psilocybin mushrooms on an online drug forum. Situating use within hybrid digital and ecological contexts, it traces shifts in user engagement before and after the 2020 COVID-19 pandemic to contextualize localized realities of the contemporary psychedelic renaissance.Design/metho...
Background: Understanding the benefits of psychedelic-assisted therapy (PAT) will require scientific attention to the causal interaction between the therapeutic context and process. Measuring what actually happens during PAT in large-scale studies will be an essential component of this work. Objective: We aim to develop and preliminarily evaluate the feasibi...
This manuscript comprehensively reviews psilocybin-assisted therapy for major depressive disorder and treatment-resistant depression. It aims to synthesize current understanding regarding its mechanisms, efficacy, safety, costs, and accessibility, comparing it with conventional antidepressant and ketamine treatments. The methodology involved a narrative synt...
Human neuroimaging studies report that psychedelics induce serotonin-2A receptor-dependent changes in functional brain reorganization, presumably reflecting neuromodulation. However, these studies often overlook the potent vasoactive effects of serotonin. Here we identified psilocybin-induced alterations in hemodynamic response functions during human functio...
Abstract Background: Psychedelics can acutely induce mystical experiences and elevated positive mood, which may contribute to the potential benefits of psychedelic therapy. However, there remains limited understanding of the occurrence and importance of specific positive emotional experiences within psychedelic therapy. Therefore, we examined the effects of ...
This phase I trial evaluates the side effects of psilocybin and how well it works under supportive care conditions in cancer survivors living with demoralization and chronic pain. Cancer patients often experience demoralization, which is characterized by feelings of hopelessness, loss of meaning, and existential distress. Psilocybin psychotherapy, together w...
This Comment explores the legal, ethical, and regulatory challenges surrounding the use of psilocybin-assisted psychotherapy for terminally ill patients under the federal Right to Try (RTT) Act. While psychedelics like psilocybin are demonstrating extraordinary therapeutic potential, particularly in easing end-of-life psychological distress, patients remain ...
This study is an open-label, single-arm, proof-of-concept study, wherein treatment resistant bipolar depression (TRBD) participants will receive one 25 mg dose of oral psilocybin accompanied by preparatory, monitoring, and integration psychotherapy sessions (psilocybin-assisted psychotherapy, or PAP). Using fMRI (functional magnetic resonance imaging), the f...
Post-Traumatic Stress Disorder (PTSD) is a debilitating mental health condition that can occur after experiencing or witnessing a traumatic event. The impact of PTSD extends beyond the individual, affecting families, communities, and society as a whole. This study aims to investigate the potential of psilocybin as a treatment for PTSD. Psilocybin, after bein...
. It remains unclear how human brain network changes relate to subjective and lasting effects of psychedelics. Here we tracked individual-specific brain changes with longitudinal precision functional mapping (roughly 18 magnetic resonance imaging visits per participant). Healthy adults were tracked before, during and for 3 weeks after high-dose psilocybin (2...
Background: Depression is a major global health challenge, affecting over 300 million people worldwide. Current pharmacological and psychotherapeutic interventions have limited efficacy, underscoring the need for novel approaches. Emerging evidence suggests that peak emotional experiences characterized by awe, transcendence, and meaning hold promise for rapi...
Psychedelics hold therapeutic promise for mood disorders due to rapid, sustained results. Human neuroimaging studies have reported dramatic serotonin-2A receptor-(5-HT2AR)-dependent changes in functional brain reorganization that presumably reflect neuromodulation. However, the potent vasoactive effects of serotonin have been overlooked. We found psilocybin-...
1 Summary The relationship between the acute effects of psychedelics and their persisting neurobiological and psychological effects is poorly understood. Here, we tracked brain changes with longitudinal precision functional mapping in healthy adults before, during, and for up to 3 weeks after oral psilocybin and methylphenidate (17 MRI visits per participant...
Context: Measuring therapeutic connection during psilocybin-assisted therapy is essential to understand underlying mechanisms, inform training, and guide quality improvement. Purpose: To evaluate the feasibility of directly observing indicators of therapeutic connection during psilocybin administration encounters. Methods: We evaluated audio and video data f...
In this review paper, we delve into the potential applicability of psilocybin - a naturally synthesized psychedelic substance found within select species of fungi, as a prospective avenue for depression treatment. Depression, a widespread psychological malady affecting countless individuals across the globe, often proves stubborn against existing treatment m...
Introduction There is a growing and renewed interest in the use of hallucinogenic drugs in the treatment of psychiatric disorders, especially since the FDA approval of ketamine treatment for resistant depression. The response to hallucinogenic psychedelic substances (ayahuasca, psilocybin, LSD, ketamine) in the treatment of depression and addictions calls fo...
IntroductionMajor depressive disorder remains a prevalent world-wide health problem. Currently available antidepressant medications take weeks of dosing, do not produce antidepressant response in all patients, and have undesirable ancillary effects.Areas coveredThe present opinion piece focuses on the major inroads to the creation of new antidepressants. The...
RationaleKetamine and psilocybin belong to the rapid-acting antidepressants but they also produce psychotomimetic effects including timing distortion. It is currently debatable whether these are essential for their therapeutic actions. As depressed patients report that the "time is dragging," we hypothesized that ketamine and psilocybin-like compounds may pr...
