Background: 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. Case presentation: We report the case of an oct...
The primary objective is to evaluate whether a single dose of psilocybin (25 mg), compared to placebo, can restore fronto-striatal reward circuit function and thereby improve anhedonia and emotional blunting in individuals with residual symptoms despite ongoing SSRI or SNRI treatment. This will be assessed using precision functional mapping (PFM), task-based...
Psilocin is a psychedelic indole alkaloid and one of the major human metabolites of its phosphorylated precursor, psilocybin. Psilocin binds to the serotonin receptor, 5-HT2A, and dose-dependently induces hallucinogenic effects stronger than psilocybin. As a result, psilocin has been a drug of interest in the analytical toxicology community for years. In viv...
The purpose of this study is to evaluate the efficacy of psilocybin on the symptom of anhedonia in individuals with treatment-resistant major depressive disorder.
PsiConnect is a large-scale neuroimaging study designed to investigate context-dependent neural and subjective effects of psilocybin using multimodal neuroimaging. It combines functional, structural, and diffusion-weighted MRI with EEG to examine brain activity in 62 participants before and after a 19 mg dose of psilocybin. The design includes resting-state ...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. There is interest to see if similar effects may be provided in those with obsessive compulsive disorder (OCD). The purpose of this study is to evaluate the safety, f...
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...
The goal of this randomized controlled trial is to evaluate the efficacy of psilocybin administered with Acceptance and Commitment Therapy (ACT) as an intervention to reduce post-traumatic stress disorder (PTSD) symptom burden in adult (aged 18-65) survivors of intimate partner violence (IPV). This trail will test the following 2 aims: AIM1: To compare the e...
Background: Social anxiety disorder is a chronic and disabling condition with limited response to standard therapies. Low-dose psilocybin may enhance the effectiveness of exposure-based treatments by modulating neural circuits associated with fear and avoidance. Virtual reality exposure therapy offers a controlled and individualized platform for intervention...
The study tries to improve our treatments for people who have obsessive-compulsive disorder (OCD) by testing psilocybin, a mind altering drug that changes activity in brain areas involved in OCD. 30 patients with moderate or more severe OCD who are not taking mind altering medications or street drugs will participate in a 12 week study. Participants will be ...
The purpose of this research study is to investigate the safety and feasibility of two (2) oral doses of psilocybin when combined with behavioral support for methamphetamine use disorder (MUD). Participants have a diagnosis of methamphetamine use disorder (MUD). Participants can expect to be actively engaged in the study for up to 26 weeks. The objective of ...
To evaluate the efficacy, safety, and durability of a single 25-mg dose of a proprietary, synthetic formulation of psilocybin with psychological support for reducing chronic suicidal ideation in a treatment-resistant population. ), and ≥2 prior antidepressant treatment failures received a single 25-mg dose of psilocybin administered within a structured prepa...
The goal of this clinical trial is to evaluate whether psilocybin therapy can effectively treat depression and psychological distress in adult patients with COPD, ALS, MS, or APD who have at least 6 months life expectancy. The main questions it aims to answer are: * Can psilocybin therapy safely reduce depressive symptoms compared to low-dose control? * Will...
Electroencephalographic (EEG) microstates provide a compact framework for characterizing the temporal organization of large-scale brain activity, yet their sensitivity to altered brain states remains insufficiently explored. In this study, we applied broadband and frequency-resolved EEG microstate analysis to resting-state EEG data from two publicly availabl...
Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of serotonin (5HT)2A receptor antagonists such as risper...
Importance: Cocaine use disorder is a serious public health problem and no medications have been proven effective for its treatment. Objective: To evaluate psilocybin in the treatment of cocaine use disorder. It was hypothesized that psilocybin, compared with placebo, would yield a higher percentage of cocaine abstinent days, a greater likelihood of complete...
Non-human models, including fish, are increasingly important for investigating how pharmacological agents such as hallucinogens influence behavior, physiology, and cellular processes. These models help to reveal underlying mechanisms and to support assessments of toxicological impact, efficacy, and safety. In this study, we used isogenic lineages of the amph...
This is a Phase 2, single-center study to explore the efficacy, safety, and tolerability of up to two 25-mg doses of psilocybin administered at an interval of 9 to 10 weeks in patients with MDD and cancer. This two-part study will administer a fixed dose (25 mg) of psilocybin in a double-blind, randomized, placebo-controlled portion (Dosing Session 1) and su...
