The psychedelic psilocybin has gained popularity in recent years as a therapy for treatment-resistant depression and has been reported to reduce symptoms of depression and anxiety. Psilocybin's active metabolite, psilocin, possesses a binding affinity for serotonin receptors as well as for the serotonin transporter (5-HTT). We recently reported that in contr...
The purpose of this study is to determine the safety and feasibility of sequencing psilocybin therapy with a short-duration, aiTBS protocol (Stanford Accelerated Intelligent Neuromodulation Therapy, or SAINT) in individuals with treatment-resistant major depressive disorder. This will be a phase II 2x2 design (device and dose) clinical trial. 100 participant...
BACKGROUND: Cognitive difficulties within treatment-resistant unipolar and bipolar depression (TRD; TRBD) often do not improve with conventional pharmacotherapies. Psilocybin-assisted psychotherapy (PAP) has shown promise as a novel intervention for TRD; however, few studies have assessed its effects on cognition in this population. METHODS: This retrospecti...
Objective: To assess the safety and efficacy of a six-week microdosing regimen of psilocybin combined with short-term, experience-based psychotherapy in patients with treatment-resistant depression who have not responded to previous pharmacological or long-term psychological interventions. Hypothesis: Compared to baseline, the group that begins with psilocyb...
BackgroundOver the past ten years, several psychedelic compounds, including tryptamines like lysergic acid diethylamide/LSD, psilocybin, ayahuasca, and dimethyltryptamine/DMT, have been tested in clinical trials for a range of psychiatric conditions, such as anxiety and depression. While these compounds are relatively available for treatment, ketamine and it...
BackgroundResults from contemporary clinical trials of serotonergic psychedelic therapies have led to an increasing focus on their potential clinical use across mental disorders. However, studies examining mechanisms of clinical response to psychedelic therapy in psychiatric populations are limited. This review aimed to synthesize evidence from studies exami...
A meta-analysis comprising 17 randomized trials has found that rates of control group improvement in depression studies were lower in psilocybin trials than in studies of esketamine or a selective serotonin reuptake inhibitor (SSRI). The results suggest that psilocybin's overall efficacy in the treatment of depression might be overestimated.
Psilocybin, a serotonin receptor agonist in the brain, significantly and quickly improves depressive symptoms while inducing profound acute subjective effects. The benefit-risk ratio of psilocybin in treatment-resistant depression seems favorable, but needs to be confirmed. Moreover, the role of 5-HT2A receptors, involved in the psychedelic experience, on th...
Psilocybin, an indoleamine alkaloid derived from various fungal species, is the subject of renewed, rigorous investigation for its therapeutic potential in psychiatry. This compound, a prodrug for the active metabolite psilocin, functions primarily as a partial agonist at the serotonin 2A (5-HT2A) receptor. Its administration within a structured psychotherap...
This retrospective observational study examines the effects of psychedelic-assisted psychotherapy (PAP) with lysergic acid diethylamide (LSD) or psilocybin in patients with treatment-resistant depressive, anxiety, or addictive disorders. Data will be analyzed from patients treated at the University Hospitals of Geneva between June 2020 and April 2025 who obt...
The purpose for this study is to observe the real world experience of participants who are receiving psilocybin in the context of (alcoholism) Alcohol Use Disorder without intervening in the model of care. The study team will engage directly with the participants to examine the outcomes in participants who have been deemed eligible and appropriate to receive...
BackgroundPsilocybin-Assisted Psychotherapy (PAP) has gained increasing attention in recent years as a potential treatment for depression, particularly in cases resistant to conventional therapies. This article aims to assess the efficacy of PAP in adults with various forms of depression by conducting a comprehensive review of the available literature.Method...

BackgroundPsychedelics are emerging as promising treatments for major depressive disorder (MDD) and treatment-resistant depression (TRD). Functional magnetic resonance imaging (fMRI) offers a powerful tool to study neural mechanisms underlying therapeutic response.MethodsThis systematic review (PROSPERO #CRD42024557973) examined neuroimaging studies of psilo...
About one in three people with major depression respond poorly to standard antidepressant treatments. This kind of depression is called treatment-resistant depression, and it can lead to long-term disability, financial challenges, and a higher risk of suicide. Psilocybin-a compound found in certain mushrooms-has shown early promise as a new treatment for thi...
BackgroundSuicidal ideation, attempts, and deaths present a major and tragic public health concern. Recent trials of psilocybin therapy (PT) have shown promise in treating treatment-resistant depression and have found a reduction in suicidal ideation. Given the growth of PT research, there is a need to further understand its effect on suicidal ideation, atte...
