Selective outcome reporting and non-reporting in trials of psychedelic drugs for mental disorders
Introduction Selective reporting of outcome data (SOR) refers to trialists selecting results for publication based on the results of a subset of the initially measured outcomes. SOR for specific, potentially very profitable, treatments, particularly in key junctures such as in the period leading to or immediately preceding approval, has not been examined. Ob...

Could psilocin rescue chronic, stress-accelerated, transcriptional aging in brain?
Brain aging (BA) processes are complex, often affect multiple systems, and frequently lead to cognitive decline and increased susceptibility to insults. BA appears to be a primary risk for the development of many prominent neurodegenerative pathologies. The US Census Bureau predicts that the aging population (65+) will represent a greater proportion of the U...
A Phase II Randomized, Double-blind, Active Placebo-controlled Parallel Group Trial to Examine the Efficacy and Safety of Psilocybin in Treatment-resistant Major Depression
The study aims to investigate the safety and efficacy of oral psilocybin administered under supportive conditions in treatment-resistant major depression (TRD). The study is a bi-centric, prospective, randomized, active placebo-controlled study investigating the effects of 25 mg and 5 mg (p.o.) psilocybin versus placebo (100 mg nicotinamide) in a psychothera...
Comparative Efficacy of Hallucinogens in Treating Mood Disorders Through a Meta-Analysis of Symptom Reduction, Dosage, and Duration
Background: Hallucinogens including psilocybin, lysergic acid diethylamide (LSD), ketamine, N,N-dimethyltryptamine (DMT) (as ayahuasca), have re-emerged as potential rapid-acting treatments for mood disorders. We conducted a meta-analysis of placebo-controlled trials evaluating their efficacy in depression and anxiety disorders. Methods: A systematic review ...
Alternative therapy for neurological and psychiatric disorders using psilocybin
Introduction: In recent years, psilocybin has been explored as an alternative therapy for neurological and psychiatric disorders, such as depression, anxiety, post-traumatic stress disorder (PTSD), and substance dependence. Studies suggest that when administered under professional supervision, psilocybin can offer relief for patients with treatment-resistant...
Multidimensional Personality Changes Following Psilocybin-Assisted Therapy in Patients With Alcohol Use Disorder: Results From a Double-Blind, Placebo-Controlled Clinical Trial
OBJECTIVE: Evidence suggests that psilocybin-assisted therapy (PAT) leads to durable shifts in personality structure. However, such changes have yet to be characterized in disorders of addiction. In this secondary analysis from a randomized controlled trial, the authors examined the effect of PAT on personality dimensions in patients with alcohol use disorde...
Psilocybin-Assisted Group Psychotherapy + Mindfulness Based Stress Reduction (MBSR) for Frontline Healthcare Provider COVID-19 Related Depression and Burnout: A Randomized Clinical Trial
Objective This clinical trial sought to evaluate the safety and preliminary efficacy of psilocybin and MBSR for frontline healthcare providers with symptoms of depression and burnout related to the COVID-19 pandemic. Methods This was a randomized controlled trial that enrolled physicians and nurses with frontline clinical work during the COVID-19 pandemic an...

Psilocybin increases emotional empathy in patients with major depression
Empathy plays a crucial role in interpersonal relationships and mental health. It is decreased in a variety of psychiatric disorders including major depression. Psilocybin, a promising candidate for treating depression, has been shown to acutely increase emotional empathy in healthy volunteers. However, no study has investigated this effect and its relevance...

Enhanced visual contrast suppression during peak psilocybin effects: Psychophysical results from a pilot randomized controlled trial
In visual perception, an effect known as surround suppression occurs wherein the apparent contrast of a center stimulus is reduced when it is presented within a higher-contrast surrounding stimulus. Many key aspects of visual perception involve surround suppression, yet the neuromodulatory processes involved remain unclear. Psilocybin is a serotonergic psych...
