Psychedelics have re-emerged as promising treatments for mood disorders. The current model provides a moderate-to-high dose of a psychedelic agent (e.g., psilocybin) to reliably induce an altered state of consciousness. Unfortunately, the hallucinatory effects limit the treatment's potential scalability given patients' vulnerability and extensive monitoring costs, leading to growing interest in...
Objective To evaluate psilocybin's efficacy in reducing depressive and anxiety symptoms in cancer patients based on randomized controlled trials (RCTs). Methods This systematic review and network meta-analysis (NMA) followed PRISMA and Cochrane Handbook guidelines. PubMed, Embase and Cochrane Library data up to July 2024 were analyzed. Two RCTs met the inclusion criteria. Changes in Beck...
Psychological and existential distress is prevalent among patients with life-threatening cancer, significantly impacting their quality of life. Psilocybin-assisted therapy has shown promise in alleviating these symptoms. This systematic review aims to synthesize the evidence on the efficacy and safety of psilocybin in reducing cancer-related distress. We searched MEDLINE, APA PsycINFO, Cochrane...
Psilocybin, a naturally occurring psychedelic compound, has garnered renewed scientific interest for its potential in treating psychiatric and neurological disorders. This review systematically examines the latest research on psilocybin’s pharmacokinetics, pharmacodynamics, clinical efficacy, and safety profile. Emerging evidence supports its efficacy in conditions such as major depressive...
Abstract Background SAPAP3-knockout (SAPAP3-KO) mice develop excessive self-grooming behavior at 4-6 months of age, serving as a model for obsessive-compulsive disorder (OCD). Given that anxiety often precedes OCD diagnosis in humans, this study investigated whether juvenile SAPAP3-KO mice exhibit anxiety-like behaviors before developing the self-grooming phenotype, and whether such behaviors...

Abstract Mental disorders are a representative type of brain disorder, including anxiety, major depressive depression (MDD), and autism spectrum disorder (ASD), that are caused by multiple etiologies, including genetic heterogeneity, epigenetic dysregulation, and aberrant morphological and biochemical conditions. Psychedelic drugs such as psilocybin and lysergic acid diethylamide (LSD) have...
Psilocybin is a serotonergic psychedelic with therapeutic potential for several neuropsychiatric disorders, including depression and anxiety disorders. Serotonin transporter (5-HTT) knockout mice (KO) are a well-validated mouse model of anxiety/depression and are relevant to both chronic treatment with serotonin transporter reuptake inhibitors (SSRIs) and polymorphisms in the serotonin...
Abstract Rationale Psychedelic-assisted therapy is increasingly applied within mental health treatment. Objectives This study focused on factors moderating changes in the acute and long-term effects of an individual psilocybin-assisted program on depression, anxiety, PTSD and personality structures by including demographic factors, subjective experience and degree of mystical type experiences...

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 disorders. Objective: The aim of...
Abstract Fifty-one cancer patients with symptoms of depression and anxiety were enrolled in a randomized, double-blind, crossover trial using low-dose psilocybin (placebo) and high-dose psilocybin (intervention group) combined with psychotherapy with 5 weeks between dosing sessions and at 6-month follow-up. Participants in the intervention group had large decreases in clinician- and self-rated...
