Methods In a phase 2, double-blind, randomized, controlled trial involving patients with long-standing, moderate-to-severe major depressive disorder, we compared psilocybin with escitalopram, a selective serotonin-reuptake inhibitor, over a 6-week period. Patients were assigned in a 1:1 ratio to receive [...]

Psilocybin for treatment-resistant depression : fMRI-measured brain mechanisms, Robin L. Carhart-Harris et al., 2017

Psilocybin for treatment-resistant depression : fMRI-measured brain mechanisms Robin L Carhart-Harris, Leor Roseman, Mark Bolstridge, Lysia Demetriou, J Nienke Pannekoek, Matthew B Wall, Mark Tanner, Mendel Kaelen, John McGonigle, Kevin Murphy, Robert Leech, H Valerie Curran & David J Nutt Nature, Scientific Reports, 2017, 7, 13187 |1-11 Doi : 10.1038/s41598-017-13282-7   Abstract Psilocybin with psychological support is showing promise as a treatment model in psychiatry but its therapeutic mechanisms are poorly understood. Here, cerebral blood flow (CBF) and blood oxygen-level dependent (BOLD) resting-state functional connectivity (RSFC) were measured with functional magnetic resonance imaging (fMRI) before and after treatment with psilocybin (serotonin agonist) for treatment-resistant depression (TRD).

Psilocybin Delivers ‘Remarkable’ Relief in Severe Depression, Batya Swift Yasgur, Medscape.com, 2020

Psilocybin Delivers 'Remarkable' Relief in Severe Depression Batya Swift Yasgur, MA, LSW Medscape Medical News, November 05, 2020   Psilocybin, the psychedelic compound in "magic mushrooms," rapidly improves symptoms and produces remission in as little as two sessions for patients with major depression, new research suggests. Results of a small randomized trial showed that treatment with psilocybin was associated with a greater than 50% reduction in depressive symptoms in 67% of study participants. In addition, 71% showed improvement at 4-week follow-up, with more than 50% achieving remission. "The finding that the majority of people whom we treated showed efficacy was quite a remarkable and gratifying finding [...]

Psilocybin Matches SSRI for Moderate-to-Severe Depression in Phase 2 Study, Sarah Edmonds, 2021

Psilocybin Matches SSRI for Moderate-to-Severe Depression in Phase 2 Study Sarah Edmonds Medscape Medical News, April 14, 2021   The psychedelic drug psilocybin performed just as well as a widely used antidepressant in easing the symptoms of major depression, and outperformed the selective serotonin reuptake inhibitor (SSRI) on a range of secondary measures, results of a small-scale phase 2 study show. In a 6-week trial that included 59 patients with moderate-to-severe depression, there was no significant difference between the impact of high-dose psilocybin on the study's primary yardstick — the 16-item Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16) — and that of selective serotonin reuptake [...]

‘Magic Mushrooms’ Effective for Severe Depression, Batya Swift Yasgur, medscape.com, 2017

'Magic Mushrooms' Effective for Severe Depression Batya Swift Yasgur, MA, LSW Medscape Medical News © 2017 October 20, 2017   Psilocybin, the psychoactive compound in “magic mushrooms,” is a promising intervention for patients with treatment-resistant depression (TRD) and appears to offer a rapid, sustained effect, new research shows. Investigators led by David Nutt, MD, PhD, professor of neuropsychopharmacology, Imperial College, London, United Kingdom, collected pre- and posttreatment fMRI data on the use of psilocybin in 19 patients with severe major depression who had failed to respond to conventional treatments. The patients experience dramatic improvements in depressive symptoms 1 day following treatment; close to half met criteria for full response at 5 [...]

Marginalisation, stigmatisation et abandon du LSD en médecine, Zoë Dubus, 2019

Marginalisation, stigmatisation et abandon du LSD en médecine Zoë Dubus Histoire, médecine et santé, 2019, 15, 87-105 Doi : 10.4000/hms.2168 https://journals.openedition.org/hms/2168 Abstracts Après avoir été l’une des substances pharmacologiques les plus étudiées des années 1950-1970, le LSD, puissant psychédélique ayant de nombreuses indications thérapeutiques, est abandonné par la communauté scientifique internationale au début des années 1970. Si des facteurs externes à la médecine ont eu un impact sur le déclin de ce médicament, il est également nécessaire de s’interroger sur les causes internes de ce rejet. Pour ce faire, une littérature anglo-saxonne émerge ces dernières années dans le champ des psychedelic studies, que nous enrichissons ici par une [...]
