In the contemporary landscape of psychiatric medicine, critical advancements have been noted in the utilization of psychoactive substances such as hallucinogens, 3,4-methylenedioxymethamphetamine (MDMA), and ketamine for the treatment of severe mental health disorders. This review provides a detailed evaluation of these substances, focusing on their mechanis...
Rationale: N-methyl-D-aspartate receptor-mediated dissociatives and serotonergic hallucinogens are being increasingly used in therapeutic interventions that involve nonordinary states of consciousness and may represent a unique mental health paradigm wherein pharmacologically induced experiences are conducive to psychological well-being. Objective: The aim o...
Depression astonishingly can be stopped instantly by electrotherapies or through some psychedelics like psilocybin. In explaining this, the traditional approaches to their antidepressant effects via "reset" models and orthosteric serotonin receptors has neglected the only serotonin channel 5HT3, which e.g. has emerged as being helpful for the neurotrophic tr...
ObjectiveThis article provides an intercultural transdisciplinary perspective on the Indigenous roots of the resurging field of psychedelic science in the management of substance use disorders (SUDs). Ritual uses of entheogens (i.e., psychedelics of natural origin) are elaborate technologies for navigating, containing, and therapeutically directing non-ordin...
With the discovery of the antidepressive effects of ketamine and the increasing withdrawal of the pharmaceutical industry from the development of new psychotropic drugs, the psychiatric research into the clinical application of hallucinogens in psychiatry has literally blossomed in the last two decades. Promising results for various treatment approaches with...
Depression is a serious psychiatric disorder with a high incidence of morbidity and mortality and psilocybin with psychotherapy has emerged as a promising potential in the treatment of depressive disorders. A review of psilocybin use in patients with depressive disorders is presented.A search was conducted investigating the use of psilocybin in patients with...
Alcohol is a harmful drug, and reducing its consumption is a significant challenge for users. Furthermore, alcohol dependence is often treatment-resistant, and no completely effective treatment model is available for chemical dependence. Classic psychedelics, such as LSD, psilocybin, and ayahuasca have been used in different clinical and pre-clinical trials,...
ObjectiveTo evaluate the comparative effectiveness and acceptability of oral monotherapy using psychedelics and escitalopram in patients with depressive symptoms, considering the potential for overestimated effectiveness due to unsuccessful blinding.DesignSystematic review and Bayesian network meta-analysis.Data sourcesMedline, Cochrane Central Register of C...
Existential distress is commonly experienced by patients diagnosed with a life-threatening illness. This condition has been shown to adversely impact quality of life and is correlated with increased suicidal ideation and requests for hastened death. While palliative care teams are experienced in treating depression and anxiety, existential distress is a dist...
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...
BackgroundPsychedelic drugs have been of interest in medicine since the early 1950s. There has recently been a resurgence of interest in psychedelics.AimsThe objective of this study is to determine the extent of the available literature on psilocybin for medical indications including the designs used, study characteristics, indications studied, doses, and au...
For decades, psychedelics have been investigated for the treatment of psychiatric disorders. Specifically, evidence suggests that psychedelics may have therapeutic potential for the treatment of alcohol use disorder. Several studies with classic psychedelics, including LSD and psilocybin, show promising results, with psychedelics decreasing alcohol drinking ...
Psychedelics are currently undergoing a scientific renaissance, with modern studies investigating therapeutic efficacy of psychedelic-assisted therapy in a range of psychiatric conditions. In particular, psilocybin-assisted therapy (PAT) has been suggested to have positive effects on patients suffering from depression and psychiatric distress associated with...
Obsessive-compulsive disorder (OCD) is a chronic mental disease that affects approximately 2% of the population. Obsessions and compulsions are troublesome for patients and may disturb their everyday activities. The pathogenesis of this disease is still not fully elucidated, but dysfunctions of serotonin-, dopamine- and glutamate-mediated neurotransmission t...
Mental health disorders and substance use disorders (SUDs) in particular, contribute greatly to the global burden of disease. Psychedelics, including entactogens and dissociative substances, are currently being explored for the treatment of SUDs, yet with less empirical clinical evidence than for other mental health disorders, such as depression or post-trau...
ObjectivesDespite advancements in policies governing psychedelic substances globally, our understanding of real-world psychedelic use and its variations across international jurisdictions remains limited. We implemented the Global Psychedelic Survey (GPS) to capture information about psychedelic consumer characteristics, access, and usage patterns around the...
The extent of changes in functional connectivity (FC) within functional networks as a common feature across hallucinogenic drug classes is under-explored. This work utilized fMRI to assess the dissociative hallucinogens Psilocybin, a classical serotonergic psychedelic, and Salvinorin-A, a kappa-opioid receptor (KOR) agonist, on resting-state FC in nonhuman p...
Background Hallucinogens attract research as alternatives to the commonly used medications to treat major depressive and anxiety disorders. Aims Assess hallucinogens’ efficacy for managing depressive and anxiety symptoms and evaluate their safety profiles. Method In five databases, we searched for randomized controlled trials of hallucinogens targeting depre...
There is an increasing demand for effective treatments for depression, particularly for individuals grappling with treatment-resistant depression. Over recent years, a surge of interest has focused on exploring the safety and efficacy of psilocybin as a potential treatment for depression. However, preliminary findings from phase 2 studies have been inconclus...
