Psychedelics may influence personality traits, but longitudinal evidence on first-time use outside clinical settings remains limited. We followed 102 first-time psychedelic users and 1066 never-users over one year among Berlin university students. Personality was assessed with the Big Five Inventory at baseline and follow-up. Linear mixed-effects models showed small relative increases in...
Psilocybin shows promise for treatment-resistant depression (TRD), but long-term data are limited. This study examined the antidepressant effect of one or two psilocybin doses with adjunct psychotherapy in TRD until twelve months. This is a naturalistic follow-up of a phase 2b, randomized, active placebo-controlled trial, where participants were randomized to receive two drug administrations...
Psychedelic-assisted therapy (PAT) has demonstrated substantial efficacy across a range of mental disorders. However, heterogeneity between patients confers differential responsiveness. This systematic review aims to explore factors which may predict therapeutic responses to PAT. A systematic search was performed from inception through to March 2024 and studies that assessed predictors of...
Importance: Psilocybin shows promise in treating depression, although limitations of previous research warrant further research. Objective: To investigate the efficacy and safety of oral psilocybin, 25 mg, with adjunct psychotherapy in treatment-resistant depression (TRD). Design, Setting, and Participants: This was a 2-center, triple-blinded (investigator, participant, rater), phase 2b, active...

Psychedelic substances have gained recognition for their therapeutic potential, but they also present challenges, with individuals occasionally experiencing distressing episodes referred to as challenging experiences or, in the recreational setting, “bad trips”. Trial therapists and physicians, but also healthcare professionals in emergency rooms, need a comprehensive strategy to effectively...
Introduction: Serotonergic psychedelics, serotonin 2A receptor agonists such as psilocybin that can result in substantially altered states of consciousness, are used in recreational and research settings. The safety of psychedelic experiences in research settings is supported by controlled physical environments, presence of clinical and medical staff to address emergent issues, screening for...

Dabei sind viele ethische Fragen aufgekommen, die noch nicht ausreichend untersucht und beantwortet wurden. Ziel Dieser Beitrag gibt einen Überblick zum Stand der klinischen...
Dreams are still an enigma of human cognition, studied extensively in psychoanalysis and neuroscience. According to the Freudian dream theory and Solms' modifications of the unconscious derived from it, the fundamental task of meeting our emotional needs is guided by the principle of homeostasis. Our innate value system generates conscious feelings of pleasure and unpleasure, resulting in the...
Psychedelics such as psilocybin have recently gained remarkable interest in both the specialist literature and the lay press because studies suggest that these substances may have great therapeutic potential in various psychiatric disorders, including major depression. However, clinical trials with psychedelic drugs pose particular methodological challenges to researchers, some of which differ...
Purpose of Review: The use of psychedelics in a therapeutical setting has been reported for the treatment of various diagnoses in recent years. However, as psychedelic substances are still commonly known for their ( illicit) recreational use, it may seem counterintuitive to use psychedelic therapy to treat substance use disorders. This review aims to discuss how psychedelics can promote and...
The efficacy of psychedelic-assisted therapies for mental disorders has been attributed to the lasting change from experiential avoidance to acceptance that these treatments appear to facilitate. This article presents a conceptual model that specifies potential psychological mechanisms underlying such change, and that shows substantial parallels between psychedelic therapy and cognitive...
