BackgroundAnorexia nervosa is a debilitating eating disorder with high mortality and chronicity rates owing to the paucity of effective existing treatments. Several clinical trials using psilocybin therapy have demonstrated therapeutic efficacy and safety in psychiatric conditions, including anorexia nervosa.AimsThis study aimed to further assess the safety,...
Primary Aim: In participants with OUD, to characterize adverse events associated with adding two psilocybin doses to a stable buprenorphine-naloxone formulation. Secondary Aim: To evaluate the effect of psilocybin treatment on the effectiveness of a buprenorphine-naloxone maintenance therapy. Secondary Aim: To evaluate the effect of concurrent buprenorphine-...
Major depressive disorder (MDD) and treatment-resistant depression (TRD) are prevalent and debilitating conditions. Over 50% of patients have inadequate response to first-line serotonergic antidepressants and are left with suboptimal treatment options. Rapid-acting and individually tailored treatments for MDD remain major unmet needs. This review discusses p...
INTRODUCTION: Psilocybin shows promise for treatment-resistant depression (TRD), but long-term data are limited. This study examined the antidepressant effect of one or two psilocybin doses with adjunct psychotherapy in TRD until twelve months. METHODS: This is a naturalistic follow-up of a phase 2b, randomized, active placebo-controlled trial, where partici...
The purpose of this review is to evaluate the possible benefits of using psilocybin(C12H17N2O4P), a naturally occurring psychoactive compound found in certain species of mushrooms, in the treatment of multiple forms of mental illness and substance abuse in either monotherapy or in conjunction with traditional psychiatric medications. The compound acts as a h...
Importance: Psilocybin has been proposed as a rapid-acting antidepressant (onset 6 weeks), but evidence from randomized clinical trials remains limited, particularly in the broader major depressive disorder (MDD) population. Objective: To assess short-term and long-term antidepressant effects of psilocybin therapy in patients with MDD. Design, Setting, and P...
This study is a 12-week (in addition to up to 30 days of screening) randomized, double-blind, placebo-controlled, parallel-group trial. The primary objective of this study is to assess the effectiveness, safety, and tolerability of single-dose psilocybin (25 mg)-assisted therapy in comparison to active placebo (1 mg micro-dose) psilocybin-assisted therapy in...
Depression and psychological distress are highly prevalent among patients with cancer and are associated with impaired quality of life, reduced treatment adherence, and poorer clinical outcomes. Standard pharmacological and psychosocial interventions often demonstrate limited efficacy or delayed onset of action in oncological and palliative settings. Psilocy...
Importance: Annual tobacco-related death estimates are 480 000 in the US and 8 million worldwide, surpassing mortality for other abused substances. Most smoking cessation interventions result in modest long-term success. Objective: To compare prolonged smoking abstinence rates in smokers receiving psilocybin plus cognitive behavioral therapy (CBT) with those...
Abstract Background: This case describes a substance-induced manic episode with psychotic features in which interaction with an AI (artificial intelligence) chatbot appeared to corroborate and reinforce the patient’s delusional thought content and to contradict medical advice. Excerpts from the patient’s interactions with the AI chatbot provide novel clinica...
Abstract Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. Although antibiotics effectively treat most cases, an estimated 10-20% of patients develop post-treatment Lyme disease (PTLD), a chronic syndrome marked by fatigue, pain, cognitive difficulties, mood disturbance, and r...
This study will examine the effect of a single high dose of psilocybin therapy (30 mg) versus a very low dose (1 mg) as an adjunctive therapy to individuals undergoing standard-of-care buprenorphine treatment for Opioid use disorder (OUD). Effects of adjunctive psilocybin will be determined for longitudinal outcomes of opioid abstinence, compliance with bupr...
Anhedonia, a core symptom of depression, is often resistant to conventional treatments and significantly impacts quality of life. This secondary analysis aimed to evaluate the effects of psilocybin-assisted psychotherapy (PAP) on anhedonia severity in individuals with treatment-resistant depression (TRD). Participants (n = 30) with TRD and a primary diagnosi...
Background: Psychedelic substances have been used for millennia in religious and healing contexts and have recently re-emerged as subjects of scientific interest due to advances in neuroscience and psychiatry. Research suggests that psychedelics may address limitations of conventional psychiatric treatments, particularly in disorders such as major depressive...
This is a double-blind, adaptive, 2-stage, multi-site, phase 2 randomized controlled clinical trial designed to evaluate effects of moderate and high dose psilocybin, relative to low-dose psilocybin control, in OUD patients who continue to use illicit opioids in spite of adherence to standard-of-care treatment with methadone. Up to 480 participations will be...
Background: Psilocybin has shown promise in neuropsychiatric disorders but presents a paradoxical relationship with seizures and epilepsy. Methods: A narrative review was conducted up to November 23, 2025. We conducted structured literature searches across PubMed/MEDLINE, Scopus, Web of Science. and Google Scholar using MeSH terms and keywords to identify st...
