Towards mapping neuro-behavioral heterogeneity of psychedelic neurobiology in humans Flora Moujaes, Katrin H. Preller, Jie Lisa Ji, John D. Murray, Lucie Berkovitch, Franz X. Vollenweider, Alan Anticevic Biological Psychiatry, 2023 doi : 10.1016/j.biopsych.2022.10.021 ABSTRACT Precision psychiatry aims to identify markers of inter-individual variability that allow predicting the right treatment for each patient. However, bridging the gap between molecular-level manipulations and neural systems-level functional alterations remains an unsolved problem in psychiatry. After decades of low success rates in pharmaceutical R&D for psychiatric drugs, multiple studies now point to the potential of psychedelics as a promising fast-acting and long-lasting treatment for some psychiatric symptoms. Yet, given the highly [...]

Weissman ACS Pharmacology & Translational Science, 2021, 4, (2), 436-451 Doi : 10.1021/acsptsci.1c00024 Abstract Use of classic psychedelics (e.g., psilocybin, ayahuasca, lysergic acid diethylamide) is increasing and psychedelic therapy is receiving growing attention as a novel mental health intervention. Suicidality remains a potential safety concern associated with classic psychedelics and is, concurrently, a mental health concern that psychedelic therapy may show promise in targeting. Accordingly, further understanding of the relationship between classic psychedelics and suicidality is needed. Therefore, we conducted a systematic review [...]

Doi : 10.1007/s00213-021-06049-6 Abstract Rationale : A broad reassessment of the potential benefits of psychedelic drugs has led to the initiation of multiple major clinical trials in an effort to advance their status to become FDA-approved medications, as well as local legislative efforts to legalize or decriminalize their use. Objectives : To use recently published data to assess potential risks and benefits of psychedelic drugs as therapeutics, as well as to synthesize what is currently known in order [...]

Doi : 10.1016/j.cell.2020.03.020 After a legally mandated, decades-long global arrest of research on psychedelic drugs, investiga- tion of psychedelics in the context of psychiatric disorders is yielding exciting results. Outcomes of neuroscience and clinical research into 5-Hydroxytryptamine 2A (5-HT2A) receptor agonists, such as psilocybin, show promise for addressing a range of serious disorders, including depression and addiction. Introduction—Why the Psychedelic Revolution in Psychiatry? Research leading to the discovery of new pharmacological treatments for psychiat- ric disorders has been painfully slow. With a few exceptions, including the use of orexin [...]

Mertens, Michael Koslowski, Felix Betzler, Gerhard Gründer and Henrik Jungaberle Frontiers in Psychiatry, February 2020 | Volume 11 | Article 5, 1-13. doi : 10.3389/fpsyt.2020.00005 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 behavioral therapy: We propose that in the carefully controlled [...]

Galvão-Coelho; Daniel Perkins Current Opinion in Psychiatry, 2022, 35, (1), 22-29. doi : 10.1097/YCO.0000000000000759 https://www.medscape.com/viewarticle/964245 Abstract and Introduction Abstract Purpose of Review: Despite advances in treatment modalities for mood disorders over recent decades, further therapeutic options are still required. Increased research is occurring, with the pursuit of psychedelic-based pharmacotherapies for a range of mood disorders and other conditions. Recent Findings: Serotonergic psychedelics have been found to modulate brain networks underlying various psychiatric disorders, as well promoting neurogenesis and neuroplasticity. Randomized placebo-controlled trials have found psilocybin with psychological support effective at [...]

O’Shaughnessy , Ilana Berlowitz, Robin Rodd, Zoltán Sarnyai and Frances Quirk Therapeutic Advances in Psychopharmacology, 2021, Vol. 11, 1–18 DOI : 10.1177/2045125320986634 Abstract Aims : The therapeutic use of psychedelics is regaining scientific momentum, but similarly psychoactive ethnobotanical substances have a long history of medical (and other) uses in indigenous contexts. Here we aimed to evaluate patient outcomes in a residential addiction treatment center that employs a novel combination of Western and traditional Amazonian methods. Methods : The study was observational, with repeated measures applied throughout treatment. All tests were administered in [...]

DOI : 10.1177/0269881120936486 Abstract Background : Ayahuasca is a traditional Amazon brew and its potential antidepressant properties have recently been explored in scientific settings. We conducted a double-blind placebo-controlled trial of ayahuasca with treatment-resistant depression patients (n = 28) and healthy controls (n = 45). Aims : We are evaluating the blood inflammatory biomarkers: C-reactive protein and [...]

Scientific interest in the therapeutic effects of classical psychedelics has increased in the past two decades. The psychological effects of these substances outside the period of acute intoxication have not been fully characterized. This study aimed to: (1) quantify the effects of psilocybin, ayahuasca, and lysergic acid diethylamide (LSD) on psychological outcomes in the post-acute period; (2) test moderators of these effects; and (3) evaluate [...]

Ayahuasca : Uses, Phytochemical and Biological Activities Edgar Antonio Estrella‑Parra · Julio Cesar Almanza‑Pérez · Francisco Javier Alarcón‑Aguilar Natural Products and Bioprospecting, 2019, 9, 251–265 doi : 10.1007/s13659-019-0210-5 Abstract Ayahuasca (caapi, yajé), is a psychoactive brew from the Amazon Basin region of South America traditionally considered a “master plant.” It is prepared as a decoction from Banisteriopsis caapi and Psychotria viridis, which it is thought that it stimulates creative thinking and visual creativity. Native healers of the Orinoco and Amazon basins have used traditionally ayahuasca as a healing tool for multiple purposes, particularly to treat psychological disorders in the patients, with some beneficial effects experimentally [...]
