Introduction: Treatment-outcome expectancies are an individual’s beliefs about how a medical or psychological intervention will affect them and others. These response expectancies represent serious potential confounds to clinical trials of psychedelic-assisted therapies for a variety of conditions because of difficulties associated with blinding psychedelic ...
One of the most important developments in psychopharmacology in the past decade has been the emergence of novel treatments for mood disorders, such as psilocybin for treatment-resistant depression. Psilocybin is most commonly found in different species of mushroom; however, the literature on mushroom and fungus extracts with potential antidepressant activity...
Psilocybin is gaining popularity as research shows potential benefits to those with anxiety, depression, and other mental health conditions. Individuals with risk factors for psychosis are typically excluded from such studies, limiting the empiric research of the risks and benefits in vulnerable populations. In the real-world setting, many individuals who se...
Recent interest in the potential therapeutic effects of psychedelics has led to investigations into their influence on molecular signaling pathways within the brain. Integrated review and analysis of different studies in this field. A systematic search was conducted across international databases including Embase, Scopus, Web of Science, and PubMed from ince...
BACKGROUND: Psilocybin offers new hope for treating mood disorders due to its rapid and sustained antidepressant effects, as standard medications require weeks or months to exert their effects. However, the mechanisms underlying this action of psilocybin have not been identified. AIMS: To investigate whether psilocybin has rapid and sustained antidepressant-...
BACKGROUND: There is growing evidence for the therapeutic effects of the psychedelic drug psilocybin for major depression. However, due to the lack of safety data on combining psilocybin with selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) and concerns that there may be a negative interaction on effica...
A single 25-mg dose of psilocybin resulted in improvement in depressive symptoms in all 15 participants in an open-label nonrandomized trial enrolling adults with bipolar II disorder. Twelve of the 15 participants met response and remission criteria at the study's 12-week endpoint.
Psychedelics are a class of hallucinogenic drugs. They have been explored particularly for treatment-resistant psychiatric illnesses. In recent years, advances in psychopharmacology have benefited thousands of patients with some type of mental disorder. Preliminary evidence has shown that psilocybin has shown promise in the treatment of psychiatric disorders...
Whereas findings from case reports and cross-sectional studies suggest that naturalistic psychedelic use may be associated with unusual visual experiences that occur after the acute pharmacological effects have subsided, such findings need to be replicated in longitudinal studies to better understand potential cause-and-effect relationships. To investigate l...
Background: Psychedelics are receiving growing interest among clinical researchers for their effects on mood and cognition. Psilocybin is one of the most widely studied classic psychedelics which has shown good safety and clinical benefit for major depression and substance use disorders. Athletes frequently sustain concussions and often experience myriad sym...
BACKGROUND: Research with the Psychedelic Experience Questionnaire/Scale (PES) focuses on questions relating to mystical experience (Mystical Experience Questionnaire (MEQ)). The psychometric potential of the non-MEQ items of the PES remains largely unexplored. AIMS: We investigated whether the PES also yields subscales besides the MEQ30 subscales. METHODS: ...
A single 25-mg dose of psilocybin administered with psychological support led to significant and sustained improvement in depressive symptoms compared with placebo in a Phase 2 study of patients with major depressive disorder. A higher number of adverse events occurred in the psilocybin group, but no serious treatment-emergent adverse events were reported. S...
BACKGROUND: In clinical studies, psychedelics including psilocybin and D-lysergic acid diethylamide (LSD) demonstrate rapid and persistent antidepressant effects. Since the effective treatment with psychedelics is usually provided with psychotherapy, it is debatable whether their prolonged efficacy can be observed in infrahuman species. Preclinical reports o...
Introduction: The classic psychedelic psilocybin has attracted special interest across clinical and non-clinical settings as a potential tool for mental health. However, despite increasing attention to challenging psychedelic experiences, few studies have explored the relevance of emotionally painful, shame-related processes with psychedelic use. Methods: Th...
Ongoing antidepressant treatment is believed to alter the psychedelic effect of psilocybin, so most psilocybin trials have required withdrawal from antidepressants before enrollment. There has been recent evidence, however, that administration of a selective serotonin reuptake inhibitor (SSRI) does not significantly alter the acute subjective effects of psil...
