Eating disorders (ED) are a group of potentially severe mental disorders characterized by abnormal energy balance, cognitive dysfunction, and emotional distress. Cognitive inflexibility is a major challenge to successful ED treatment and dysregulated serotonergic function has been implicated in this symptomatic dimension. Moreover, there are few effective tr...
Classic psychedelics, lysergic acid diethylamide, psilocybin, mescaline and N,N-dimethyltryptamine, are potent psychoactive substances that have been studied for their physiological and psychological effects. However, our understanding of the potential interactions and outcomes of using these substances are used in combination with other psychoactive drugs i...
The recent publication in the Journal of Affective Disorders titled "Increased low-frequency brain responses to music after psilocybin therapy for depression" identified significant region-of-interest based effects of treatment in the task scans. In this letter to the editor, I am hoping to raise methodological concerns with regards to the ANOVA ROI analysis...
This Special Issue of Neuropharmacology on psychedelics provides a timely and comprehensive update on progress following the previous Neuropharmacology Special Issue "Psychedelics: New Doors, Altered Perceptions". Remarkable advances have been made in basic and clinical research on psychedelics in the five years since 2018. It is partly based on the seminar ...
Clinical trials of pharmacological approaches targeting the core features of autism have failed. This is despite evidence from preclinical studies, genetics, post-mortem studies and correlational analyses linking peripheral and central markers of multiple candidate neurochemical systems to brain function in autism. Whilst this has in part been explained by t...
Depression is the most commonly experienced mood state over the life span in individuals with bipolar disorder (BD) and is the primary driver of functional impairment and suicidality in BD. Despite this, there are few effective treatments for BD depression, with only a handful of atypical anti-psychotics and inconsistent evidence for traditional mood stabili...
Objective: To synthesize the neurobiological basis of brain-resetting effects of psilocybin and identify neuroimaging correlates of psilocybin response in depressed patients.Data Sources: MEDLINE(R), Embase, APA PsycINFO, Cochrane, and CINAHL were systematically searched on June 3, 2022, with no date restrictions using the following string: (psilocybin) AND ...
Psilocybin, a naturally occurring hallucinogenic component of magic mushrooms, has significant psychoactive effects in both humans and rodents. But the underlying mechanisms are not fully understood. Blood-oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is a useful tool in many preclinical and clinical trials to investigate ps...
The primary objective of the RECAP Study Program is to investigate the role played by conscious experience in the antidepressant effects of the psychedelic agent psilocybin. This pilot dosing study (PILOT RECAP) is designed to determine the optimal dose of midazolam that allows a psychedelic experience to occur while inducing amnesia for the experience. This...
Successful therapy of mental disorders is very important in view of the high level of suffering of those affected. Since established pharmaceutical and psychotherapeutic approaches do not lead to the desired improvement in all cases, complementary or alternative treatment methods are intensively researched. Psilocybin-assisted psychotherapy seems particularl...
Fungi produce diverse metabolites that can have antimicrobial, antifungal, antifeedant, or psychoactive properties. Among these metabolites are the tryptamine-derived compounds psilocybin, its precursors, and natural derivatives (collectively referred to as psiloids), which have played significant roles in human society and culture. The high allocation of ni...
Chronic pain is a leading cause of disability, reduced productivity, healthcare seeking behavior, and a contributor to opioid overdose in the United States. For many people, pain can be satisfactorily managed by existing medicines and comprehensive psychosocial treatments. For others, available treatments are either ineffective or not acceptable, due to side...
AbstractDemoralization as cancer-related mental health needs to be understood and addressed by clinical staff. This review systematically examined the characteristics and outcomes of interventions for demoralization in patients with cancer. Seven databases-PubMed, PsycINFO, Cinahl, Embase, Web of Science, Medline, and Cochrane Library Databases of Systematic...
Psychedelic substances are under investigation in several drug development programs. Controlled clinical trials are providing evidence for safe and effective use of psychedelic therapies for treating mental health conditions. With the anticipated FDA approval of MDMA-assisted therapy for posttraumatic stress disorder in 2023 and psilocybin therapy for depres...
Major depressive disorder presents a substantial global health burden, and at least 30-40% of patients exhibit treatment resistance to antidepressants. Ketamine, an NMDA receptor antagonist, is used as an anesthetic agent. In 2019, the U.S. Food and Drug Administration (FDA) approved esketamine (the S-enantiomer of ketamine) as a therapeutic agent for treatm...
There is increasing interest in exploring the therapeutic potential of psychedelics in treatment-resistant depression (TRD). Classic psychedelics (such as psilocybin, LSD, ayahuasca/DMT), and atypical psychedelics (such as ketamine) have been studied in TRD. The evidence for the classic psychedelics TRD is limited at the present time; early studies however s...
