High ventilation breathwork (HVB) is increasingly used in psychotherapeutic and contemplative contexts to induce altered states of consciousness (ASC), yet its neurobiological mechanisms remain poorly understood. Thirty experienced HVB practitioners (mean age 44.97 ± 11.80 years) underwent perfusion and resting-state fMRI to assess acute cerebrovascular and post-acute network changes. Cerebral...

Treatment-resistant depression (TRD) remains a major clinical challenge, with highly variable responses to ketamine. Immune activation characterizes a subset of patients with TRD. The kynurenine pathway (KP), which integrates immunometabolic signals with glutamatergic neurotransmission, may provide candidate biomarkers to inform personalized treatment. We investigated whether KP metabolites and...

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 therapy is commonly understood as a form of psychotherapy. However, despite promising results from clinical trials, scientific progress has been hindered by a lack of theoretical integration between the fields of psychedelic and psychotherapy research. This article seeks to bridge this divide by outlining a transtheoretical understanding of psychedelic-occasioned psychological...

Novel antidepressive substances are challenging the explanations for the mechanisms of action of traditional psychopharmacology. What could be the shared effects of various antidepressants and in this context what role do extrapharmacological factors, such as the body and environment, play? The available literature on clinical and preclinical data for assumed combined active factors of...

Clinical studies with psilocybin in combination with psychotherapy show promising results for the treatment of various mental disorders; however, there still exists a lack of knowledge, rejection and prejudice towards this new form of therapy among doctors, psychotherapists and patients. The aim of this study was to gain a representative impression, as far as possible, of the level of...

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...

Treatment with psilocybin differs fundamentally from classic psychopharmacotherapy. Its potentially transdiagnostic, rapid, and sustainable efficacy and its positive effect on further dimensions of mental health beyond the patient's symptoms and psychopathology imply that it may have diseasemodifying and salutogenic mechanisms of action. Psychotherapy accompanied by the administration of...

Background: Therapeutic and salutogenic effects of psychedelic drugs have been attributed to psychotherapeutic or psychotherapy-like processes that can unfold during the acute psychedelic experience and beyond. Currently, there are no psychometric instruments available to comprehensively assess psychotherapeutic processes (as conceptualized by empirical psychotherapy research) in the context of...

Psychedelic drugs including psilocybin and LSD are undergoing clinical trials for a range of psychiatric and neurological conditions, and have particularly shown substantial promise in phase 2 studies of depression. In this article we outline key knowledge gaps that may be imperative for a successful implementation of psychedelic drugs as medicines as identified by members of the European...

Neuroinflammatory processes in depression are associated with treatment resistance to conventional antidepressants. Ketamine is an effective new therapeutic option for treatment-resistant depression (TRD). Its well-established immunomodulatory properties are hypothesized to mediate its antidepressant effect. In this context, higher levels of inflammation may predict a better treatment response....

Treatment of psychiatric disorders with psychedelic substances represents one of the most promising current treatment approaches in psychiatry. Since its inception in the 1950s, therapy with psychedelics has been conceptualised as psychedelic-assisted psychotherapy-ie, a form of psychotherapy that uses the profound biological effects of this class of substances as a catalyst for changing...

Psychedelics, such as psilocybin represent one of the most promising current therapeutic approaches in psychiatry. Psychedelics seem to have not only potent antidepressant effects. Do they also work particularly quickly, i.e. within one day? The available literature on clinical studies of psychedelics in depressive syndromes is presented both from the period up to the prohibition of these...

Abstract Serotonergic psychedelics such as psilocybin, lysergic acid diethylamide (LSD), or dimethyltryptamine (DMT), as well as psychoactive drugs that trigger phenomenologically- related experiences like 3,4-methylenedioxymethamphetamine (MDMA) and ketamine, belong to the most promising treatment approaches in contemporary psychiatry. Psychedelic-assisted psychotherapy is not only a new...

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...
