Alcohol use disorder is a psychiatric condition characterized by excessive alcohol consumption. The drugs that are used to treat it often fail to prevent relapse. At the same time, psilocybin is increasingly being investigated for the treatment of various substance use disorder. This review aims to evaluate the results of the most recent clinical trials asse...

In recent years psychedelics have gained popularity and potential promise in the field of mental health, but for patients diagnosed with bipolar disorder (BD), fears of emerging manic or psychotic symptoms have caused investigators to exclude them from psychedelic research. In this observational study, we explore the motivations, expectations, and personalit...

Psychedelic research is progressing at breakneck speed and is creating new challenges for drug developers, regulatory authorities, and legislators. Most "classic" psychedelics undergoing clinical investigation are C-I controlled drugs with perceived high potential for abuse and no medical use.

BackgroundThe treatment of major depressive disorder (MDD) with available antidepressant drugs is characterized by considerable ineffectiveness. Classical psychedelics such as psilocybin and N,N-dimethyltryptamine (DMT), which act primarily as 5-hydroxytryptamine 2A (5-HT2A) receptor agonists, have shown preliminary efficacy for inducing long-term remission ...

Depression is primarily treated with selective serotonin reuptake inhibitors (SSRIs), which are limited by delayed onset of effects and low rates of remission. Recent studies showed that serotonergic psychedelics such as psilocybin can reduce depressive symptoms both rapidly and enduringly. Such effects have been associated with the activation of the seroton...

Human neuroimaging studies report that psychedelics induce serotonin-2A receptor-dependent changes in functional brain reorganization, presumably reflecting neuromodulation. However, these studies often overlook the potent vasoactive effects of serotonin. Here we identified psilocybin-induced alterations in hemodynamic response functions during human functio...

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...

Abstract Psychedelics such as psilocybin have been linked to enhanced neuroplasticity and symptom relief in affective disorders, but the neurobiological mechanisms and impact of environmen-tal context remain unclear. Here, we tested whether a single dose of psilocybin alters synap-tic density in healthy individuals and whether setting-dependent subjective ex...

Psilocybin and lisuride are 5-HT2A receptor agonists, but only psilocybin elicits the head twitch response (HTR) in rodents, a behavior commonly used as a proxy for hallucinogenic activity.
