Alcohol use disorder (AUD) is a highly prevalent disorder with limited therapeutic options. The central amygdala (CeA) is a critical brain region as dysregulation within the CeA and the corticotropin-releasing factor (CRF) system are associated with AUD pathology. CeA CRF1 receptors regulate alcohol drinking and have served as a therapeutic target in alcohol...

Background/importanceChronic pain affects many people globally, requiring alternative management strategies. Psilocybin is gaining attention for its potential in chronic pain management despite being classified as Schedule I.ObjectiveThis systematic review critically evaluates the evidence for psilocybin, a Schedule I substance, in the treatment of chronic p...
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...
Many neuropsychiatric conditions, including depression, involve synaptic loss and atrophy of the prefrontal cortex. The rapid regrowth of cortical neurons has been hypothesized to explain the rapid and enduring therapeutic effects of psychedelics and the dissociative anesthetic ketamine. However, safety concerns related to hallucinogenic/dissociative propert...
Psychedelic-assisted therapies are re-emerging as credible options in psychological care amid a high global burden of mental ill-health and limited response to first-line treatments. Once marginal, psychedelics are now part of mainstream research and policy debate, while remaining illegal or tightly restricted in many jurisdictions. Classic and atypical comp...
The primary aim is to determine the feasibility of enrolling and 15 women with chronic pelvic pain (CPP) that have failed one conventional for CPP to obtain preliminary safety data on a single administration of a moderate dose of pharmaceutical grade psilocybin (25 mg) in combination with psychotherapy sessions (two pre-dose preparatory and three post-dose i...
Chronic pain and mood disorders co-occur, exacerbate one another and share neurobiological mechanisms, but whether a single intervention could promptly alleviate both conditions remains unclear. Here, in two chronic pain models, we show that a single dose of psilocybin induces a rapid and sustained reversal of both mechanical allodynia and anxiodepression-li...
Serotonergic psychedelics have shown promise in clinical trials for treating an array of mental health disorders, including depression, anxiety, and post-traumatic stress disorder. Despite these findings, our understanding of how these drugs mechanistically exert their therapeutic effects remains incomplete. While researchers have regularly employed rodent p...
Major depressive disorder (MDD) is a complex and debilitating condition affecting approximately 280 million people worldwide. Its heterogeneous nature makes it difficult to establish clinical treatment guidelines that address individual differences in treatment response. As a result, many individuals experience treatment-resistant depression (TRD) failing to...
Anorexia nervosa (AN) is an eating disorder characterized by compulsive eating restrictions and cognitive inflexibility, which is linked to dysregulation within the cortico-striatal-thalamo cortical (CSTC) circuitry. Dysfunction within the dorsolateral prefrontal cortex and dorsal striatum has been implicated in habitual decision making and impaired cognitiv...
Introduction: Recently, there has been a significant increase in interest in the use of psychedelics for various psychiatric conditions. Psilocybin is receiving particular attention as a psychoactive substance with significant therapeutic potential. Recent research focuses on its possible benefits in the treatment of major depressive disorders (MDD) and anor...
Psychedelics are undergoing a clinical research renaissance, with compounds such as psilocybin advancing to Phase 3 trials for treatment-resistant depression and receiving fast-track or breakthrough designations from regulatory agencies. Despite this progress, the field lacks standardized terminology to guide clinical development, dosing, safety monitoring, ...
OBJECTIVE: Due to the boom in the use of certain psychedelics in different neuropsychiatric conditions, the objective was to synthesize the available information on the use of psilocybin (a psychedelic) in the population with autism spectrum disorder (ASD; a developmental neuropsychiatric condition). METHODS: Scoping review. Question framework: Population: p...
Importance Depression is a major cause of disability worldwide, motivating substantial interest in psilocybin as a potential treatment. Objective To conduct a systematic review and meta-analysis of psilocybin’s impact on depressive symptoms and provide a living open data resource. Data Sources PubMed, Embase, Scopus, Web of Science, and PsycINFO retrieved by...
Treatment resistant depression (TRD) is frequently encountered in clinical practice. The lack of response of the condition to conventional medications and augmentation strategies has spawned the search for novel treatment approaches. Psychedelic medications used in conjunction with intensive psychotherapy, so-called psychedelic-assisted psychotherapy (PAP), ...
Psilocybin, a compound found in Psilocybe mushrooms, is emerging as a promising treatment for neurodegenerative and psychiatric disorders, including major depressive disorder. Its potential therapeutic effects stem from promoting neuroprotection, neurogenesis, and neuroplasticity, key factors in brain health. Psilocybin could help combat mild neurodegenerati...
Depression, a common mental disorder, affects people at different stages of life.Classic antidepressant treatment is generally effective, however, it is prolonged.Nonetheless, numerous patients who undergo various classic antidepressant therapies still suffer from depression.Therefore, the search for novel medications is essential.In this review, we explore ...
