Despite being induced by a transient pharmacological exposure, psychedelic experiences can catalyze enduring psychological transformation, presenting a central challenge for understanding the mechanism of action of psychedelic medicines. To address this challenge, the Allostatic Reset Model (ARM) of psychedelic action is proposed, which conceptualizes psychedelic therapeutic effects as a...
The use of psychedelics in the treatment of psychopathologies has been expanding, highlighting Psychedelic-Assisted Psychotherapy (PAP) as a promising resource in mental health care. This systematic review investigates. This systematic review investigates whether and how cognitive-behavioral therapies are integrated with psychedelic substances—both classical and atypical—for the treatment of...

Major depressive disorder is highly prevalent and disabling, and many patients do not respond to standard therapies, resulting in treatment-resistant depression (TRD). Progress in TRD requires preclinical models with poor response to conventional treatments. The Wistar-Kyoto rat exposed to chronic mild stress (WKY/CMS) offers a robust paradigm: it shows limited responsiveness to standard...
CONTEXT: People living with serious illness frequently experience intense existential suffering related to awareness of finitude. Psychedelic-assisted therapies have been associated with reductions in death anxiety and existential distress, yet the experiential processes underlying transformations in the relationship with finitude remain insufficiently understood. OBJECTIVES: To synthesize...
Abstract Adolescent refractory mental health disorders are rising globally, contributing to long-term morbidity and substantial societal burden. Conventional psychotropic medications and psychotherapeutic approaches sometimes fail to provide adequate relief, necessitating an interest in novel investigational interventions. Classic psychedelic compounds—Psilocybin, Lysergic Acid Diethylamide...

Background/Objectives: Psilocybin has re-emerged as a promising intervention for neuropsychiatric disorders including major depressive disorder, treatment-resistant depression, anxiety associated with life-threatening illness, obsessive compulsive disorder, and substance use disorders. However, conventional randomized controlled trials (RCTs)-the current gold standard in evidence-based...
Major depressive disorder is a highly prevalent psychiatric condition that can affect individuals across the lifespan, yet its pathophysiology remains incompletely understood. Classical hypotheses, informed by preclinical and clinical studies, emphasized dysregulated monoaminergic neurotransmission and guided the development of widely prescribed antidepressants, including selective serotonin...
Psilocybin, chemically known as (4-phosphoryloxy-N, N-dimethyltryptamine, 4-PODMT), is derived from the psychoactive mushroom genus, Psilocybe. Of the four active metabolites, psilocin readily enters systemic circulation. The psychoactive effects of psilocin are thought to arise through partial agonist effects at the 5-HT2A receptor. Psychedelic drugs, including psilocybin, are having a...
INTRODUCTION: After decades of regulatory marginalization, psychedelic compounds have reemerged as promising therapeutic tools in psychiatry, driven by unmet clinical needs in treatment-resistant mental disorders and by growing evidence of rapid and sustained effects on mood, cognition, and behavior. AREAS COVERED: This narrative review critically examined the current clinical and regulatory...
While the limitations of existing treatment options have spurred investigations into the applicability of psychedelic therapies for chronic and treatment-resistant psychological disorders, there remain significant unresolved issues pertaining to how these treatments should be regulated and the implementation of an ethical framework for their widespread delivery in practice. Research...
