ABSTRACT Psychedelics such as psilocybin and lysergic acid diethylamide (LSD) exert hallucinogenic effects through stimulation of serotonin 5-HT2A receptors (5-HT2ARs) in the cerebral cortex. In recent years, numerous reports have demonstrated that psychedelics are effective in treating various psychiatric disorders such as major depressive disorder (MDD), t...
The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in...
There is growing interest in psychedelic compounds such as psilocybin, 3,4-metheylenedioxymethamphetamine (MDMA), lysergic acid diethylamide (LSD), and dimethyltryptamine (DMT) given emerging research on potential uses as treatments for a variety of health conditions. The United States Food and Drug Administration (FDA) has granted multiple “Breakthrough The...
The past decade has seen a huge increase in clinical research with psychedelic drugs and 3,4-methylenedioxymethamphetamine (MDMA), which have revealed great potential for treating mental health conditions. Given this progress in research, as well as the current unmet clinical need of millions of patients, in 2023, the Australian Therapeutic Goods Administrat...
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N-dimethyltryptamine, ayahuasca; non-hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g. ibogaine, ketamine and esketamine; and other atypicals e.g. dextrom...
Psychedelics have garnered great attention in recent years as treatments for major depressive disorder (MDD) and treatment-resistant depression because of their ability to alter consciousness and afflicted cognitive processes with lasting effects. We aimed to characterise how psychedelics are currently being investigated to treat substance use disorders (SUD...
PurposeMajor depressive disorder (MDD) is a heterogeneous, debilitating disorder. A distinct subgroup within the MDD spectrum is identified to have treatment-resistant depression (TRD). There is an impetus to find alternative treatments for TRD to reduce disease burden and improve quality of life. Psychedelics have been used in the treatment of various psych...
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...
This study is being conducted to evaluate how of 30 days of intermittently microdosed psilocybin affects mood, cognition, subjective well-being and structural/functional MRI results compared to a placebo. Investigators hypothesize that compared to placebo, 30 days of intermittently microdosed psilocybin will produce observable changes in mood, cognition, sub...
Treatment-resistant depression (TRD) remains a major clinical challenge and is typically defined as the persistence of depressive symptoms despite at least two adequate antidepressant trials. Individuals with TRD experience substantial morbidity, impaired functioning, and elevated suicide risk, highlighting the need for therapeutic strategies beyond incremen...
This scoping review aims to comprehensively map and synthesize the breadth of evidence from original research on the relationship between psilocybin and health, spanning clinical trials, epidemiological surveys, mechanistic experiments, and cross-sectional attitudinal studies. The review uses 145 references and builds its evidence map from 216 original studi...
The purpose of this multi-site randomized controlled trial is to evaluate the efficacy and risks of psilocybin for the treatment of depression in U.S. military Veterans with and without (±) concurrent posttraumatic stress disorder. Treatment-resistant depression (TRD) is a serious mental health problem in Veterans, frequently comorbid with post-traumatic str...
Limit: 5000 characters. 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 certain medications such as r...
PURPOSE: Expectations strongly shape participant experiences in clinical trials, contributing to placebo effects that complicate interpretation of outcomes. While quantitative tools exist to measure expectations, their subjective and multidimensional nature, especially for individuals with treatment-resistant depression (TRD), remains underexplored. This stu...
Patients with treatment-resistant depression who received psilocybin-assisted psychotherapy showed clinically meaningful improvement in depressive symptoms relative to placebo, a Phase 2b trial has found. However, the study did not show a significant effect on the primary outcome of treatment response 6 weeks after the first of two doses of psilocybin. Study...
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...
ABSTRACT Treatment-resistant depression (TRD) is characterized by chronic symptoms, impaired functioning, and limited response to conventional antidepressant therapy. Contemporary reviews have highlighted increasing interest in psilocybin-assisted therapy as a mechanistically novel approach for depressive disorders, grounded in early feasibility work demonst...
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.
