Interest in the use of serotonergic agonists such as psilocybin in treatment-resistant depression (TRD) has grown more quickly than the evidence on which to base a final opinion, as emphasized by McIntyre et al1 in their review. Psilocybin, once metabolized to psilocin, activates 5-HT2A receptors, enhancing GABA function in local circuits in the cortex and i...
Tryptamines, a class of 3-aminoethyl-indoles that activate the serotonin receptor, show potential for novel mental health treatments. The FDA has granted "breakthrough therapy designation" to psilocybin and MDMA for treatment-resistant depression, major depressive disorder, and post-traumatic stress disorder, sparking global research efforts. Various clinica...
Psychedelics as therapeutic agents have generated significant attention from clinicians and media sources in recent years. The authors provide an update to the psychiatric trainee on the evidence for psychedelics in the treatment of major depressive disorder and treatment-resistant depression. Many modern clinical trials of the classic, serotonergic psychede...
Background: Recent studies suggest that one to two administrations of psilocybin have acute antidepressant effects for people with major depressive disorder. These data on psilocybin have generated considerable enthusiasm, but little empirical attention has been paid to the therapy that adjoins psilocybin treatment (psychedelic-assisted therapy, or PAT). Mat...
Importance: Psilocybin shows promise as a treatment for major depressive disorder (MDD). Objective: To evaluate the magnitude, timing, and durability of antidepressant effects and safety of a single dose of psilocybin in patients with MDD. Design, Setting, and Participants: In this phase 2 trial conducted between December 2019 and June 2022 at 11 research si...
The pharmacological treatment of depression consists of taking antidepressant drugs for prolonged periods; its modest therapeutic effect can often be associated with significant adverse effects, while its discontinuation can lead to relapses. Psilocybin is today a novel and breakthrough therapy for major depression. It is a natural alkaloid in Psilocybe mush...
This perspective paper explores the choice of psychotherapy for psilocybin-assisted psychotherapy for treatment-resistant depression. There is evidence to support the use of some psychotherapies in treating 'treatment-resistant' depression, and emerging evidence for the efficacy of psilocybin. The next step which is the focus of this paper is to identify psy...
Introduction: The word “psychedelic” derives from the Greek language and can be loosely translated as “mind manifesting” which is to convey that these substances allow the mind to unleash its hidden potential. Psilocybin is considered to be a “classic psychedelic” and is most commonly found in the form of so-called “magic mushrooms”. Due to its unique proper...
OBJECTIVE: This study invited providers who care for patients with eating disorders to inform engagement, communication, and collaboration with psilocybin-assisted psychotherapy interventions. METHOD: Medical and mental health providers who treat patients with eating disorders were recruited via professional referral networks and participant driven sampling ...
The purpose of this study is to see if psilocybin, an investigational drug, is safe and well tolerated. Researchers also want to know if psilocybin can improve symptoms of depression. This study will see if psilocybin is safe and well tolerated by tracking changes in suicidal thoughts and behaviour, monitoring if any participants choose to stop participating...
This study is an open-label, single-arm, within-subjects design in individuals with mild-moderate Major Depressive Disorder (MDD). All participants will receive a single dose of 25mg of psilocybin in a therapeutic setting. In order to investigate the effects of length of time on SSRI therapy, 30 participants with varying lengths of time on SSRI therapy will ...
BACKGROUND: Randomised controlled trials (RCTs) of psilocybin have reported large antidepressant effects in adults with major depressive disorder and treatment-resistant depression (TRD). Given psilocybin's psychedelic effects, all published studies have included psychological support. These effects depend on serotonin 2A (5-HT2A) receptor activation, which ...
Mood disorders are recurrent/chronic diseases with variable clinical remission rates. Available antidepressants are not effective in all patients and often show a relevant response latency, with a range of adverse events, including weight gain and sexual dysfunction. Novel rapid agents were developed with the aim of overcoming at least in part these issues. ...
Major depressive disorder (MDD) is a chronic relapsing psychiatric disorder. Conventional antidepressants usually require several weeks of continuous administration to exert clinically significant therapeutic effects, while about two-thirds of the patients are prone to relapse of symptoms or are completely ineffective in antidepressant treatment. The recent ...
Abstract Psychoactive substances such as psilocybin and 3,4-methylenedioxy-methamphetamine (MDMA) are currently being investigated for a variety of psychiatric indications including major depressive disorder and post-traumatic stress disorder. It is critical that clinicians working in the mental health field understand the regulatory framework that balances ...
This article presents the case of a young woman in her mid-twenties with a history of depression since childhood. She lived with a mother who failed to take care of her. The patient cared for the emotional needs of the mother instead of the mother caring for the daughter's needs. Her father was mostly absent. Already around the age of thirteen, the patient w...

Psilocybin therapy is an emerging intervention for depression that may be at least as effective as standard first-line treatments i.e., Selective Serotonin Reuptake Inhibitors (SSRIs). Here we assess neural responses to emotional faces (fear, happy, and neutral) using Blood Oxygen-Level Dependent (BOLD) functional Magnetic Resonance Imaging (fMRI) in two gro...
Abstract Background Psilocybin Therapy (PT) is being increasingly studied as a psychiatric intervention. Personality relates to mental health and can be used to probe the nature of PT's therapeutic action. Methods In a phase 2, double-blind, randomized, active comparator controlled trial involving patients with moderate-to-severe major depressive disorder, w...
12021 Background: Up to 25% of people living with cancer have depression. Existing psychological interventions have limited efficacy in treating depression. Psilocybin, a 5-hydroytrptamintergic psychedelic, coupled with group therapy is safe and effective in ameliorating symptoms of depression (Agrawal et al, ASCO2022). Response to psilocybin treatment was o...
