This work utilized fMRI to assess the influence of the psychedelics, Psilocybin, a serotonergic agonist, and Salvinorin-A, a kappa-opioid receptor (KOR) agonist, on functional connectivity (FC) in non-human primates. We used a seed-based FC analysis, probing regions of interest associated with psychedelic hallucinogens. Our findings highlight the overlapping...
Abstract Effective interventions for neuropsychiatric disorders may work by rebalancing the brain’s functional hierarchical organization. Here we directly investigated the effects of two different serotonergic pharmacological interventions on functional brain hierarchy in major depressive disorder in a two-arm double-blind phase II randomized controlled tria...
This article discusses evidence that offers insights into the effects of psilocybin on the brain and its potential role in alleviating the symptoms of some neuropsychiatric conditions.
The goal of this study is to assess the effectiveness of psilocybin for the treatment of Major Depressive Disorder and potential therapeutic mechanisms. Enrolled participants will receive a single active dose of psilocybin, or a dose considered high enough to treat depression, administered orally with accompanying psychological support.
Post-Traumatic Stress Disorder (PTSD) is a debilitating mental health condition that can occur after experiencing or witnessing a traumatic event. The impact of PTSD extends beyond the individual, affecting families, communities, and society as a whole. This study aims to investigate the potential of psilocybin as a treatment for PTSD. Psilocybin, after bein...
Abstract Recent clinical trials have found that the serotonergic psychedelic psilocybin effectively alleviates anxiodepressive symptoms in patients with life-threatening illnesses when given in a supportive environment. These outcomes prompted Canada to establish legal pathways for therapeutic access to psilocybin, coupled with psychological support. Despite...
Psilocybin has reemerged as a promising treatment for difficult-to-treat depression (DTD). Although there is limited evidence regarding interactions between psilocybin and other psychotropic drugs, clinical trials require that patients discontinue their antidepressants before study entry to isolate the benefits of psilocybin and to minimize the risk of adver...
In the past few years, psilocybin, a psychedelic compound found in "magic mushrooms" (psilocybin mushrooms), has undergone decriminalization in numerous cities across the US and has been legalized in Oregon and Colorado. Proponents of psilocybin decriminalization have emphasized its therapeutic potential in treating mental health disorders. Furthermore, psil...
BACKGROUND: Major depressive disorder (MDD) is a leading cause of disability worldwide across domains of health and cognition, affecting overall quality of life. Approximately one third of individuals with depression do not fully respond to treatments (e.g., conventional antidepressants, psychotherapy) and alternative strategies are needed. Recent early phas...
Background: Chronic pain is a leading cause of disability worldwide. Fibromyalgia is a particularly debilitating form of widespread chronic pain. Fibromyalgia remains poorly understood, and treatment options are limited or moderately effective at best. Here, we present a protocol for a mechanistic study investigating the effects of psychedelic-assisted-thera...
Key Clinical Message: Long-COVID syndrome lacks effective holistic treatment options. We present a case of a 41-year-old fully vaccinated female with Long-COVID syndrome who obtained significant symptomatic relief after self-medicating with psilocybin and MDMA. Abstract: Long-COVID, a syndrome persisting after the acute phase of coronavirus disease 2019 (COV...
Serotonergic psychedelics hold promise as a treatment modality for various psychiatric disorders and are currently applied in psychedelic-assisted psychotherapy. We investigated the learning effects of the serotonin receptor agonist psilocybin in a probabilistic cue-reward task with emotional cues in the form of neutral or fearful faces, presented either con...
For a new clinical trial testing a group retreat-based format of psilocybin-assisted therapy, our research team created an initial set of practice guidelines that aimed to describe facilitator use of touch in a way that is ethical, supportive, and minimizes harm. In our first three retreats, however, we had two unexpected experiences with touch that led us t...
Several phase II studies have demonstrated that psilocybin-assisted therapy shows therapeutic potential across a spectrum of neuropsychiatric conditions, including major depressive disorder (MDD). However, the mechanisms underlying its often persisting beneficial effects remain unclear. Observational research suggests that improvements in psychological flexi...
To the Editor According to the study protocol, the recently published study by Aaronson et al1 was carried out “to assess effectiveness of 25 mg of psilocybin in [15] patients with treatment-resistant type 2 bipolar depression.” We see 3 concerns.
Psilocybin ist ein Indolalkaloid aus der Gruppe der Tryptamine und wird zur Behandlung behandlungsresistenter Depressionen (TRD) untersucht. Da die Einnahme von Antidepressiva die psychedelische Wirkung von Psilocybin potenziell verändern kann, werden diese vor Studienbeginn regelhaft ausgeschlichen. Goodwin et al. dagegen wollten prüfen, ob Psilocybin eine ...
In this study, for the first time, we explored a dataset of functional magnetic resonance images collected during focused attention and open monitoring meditation before and after a five-day psilocybin-assisted meditation retreat using a recently established approach, based on the Mapper algorithm from topological data analysis. After generating subject-spec...
