Nous retracerons l’histoire de la découverte des champignons divinatoires du Mexique et des recherches thérapeutiques qu’elle a suscitées, depuis les années 1950, avec les observations ethnographiques et les collectes des époux Wasson, jusqu’à la « renaissance psychédélique », qui caractérise ces deux dernières décennies marquées par le regain d’intérêt porté à ces substances [...]

The experimental effects of psilocybin on symptoms of anxiety and depression : A meta-analysis Simon B. Goldberg, Brian T. Pace, Christopher R. Nicholas, Charles L. Raison, Paul R. Hutson Psychiatry Research, 2020, 284,  112749 Doi : 10.1016/j.psychres.2020.112749   A B S T R A C T The current meta-analysis examined the effects of psilocybin in combination with behavioral interventions on anxiety and depression in samples with elevated symptoms. Across four studies (one uncontrolled; three randomized, placebo-controlled; N = 117), within-group pre-post and pre-follow-up effects on anxiety and depression were large (Hedges’ gs=1.16 to 1.47) and statistically significant. Across three placebo-controlled studies, pre-post placebo-controlled effects were also [...]

Post-acute psychological effects of classical serotonergic psychedelics : a systematic review and meta-analysis, Simon B. Goldberg et al, 2020,

Post-acute psychological effects of classical serotonergic psychedelics: a systematic review and meta-analysis Simon B. Goldberg, Benjamin Shechet, Christopher R. Nicholas, Chi Wing Ng, Geetanjali Deole, Zhuofan Chen and Charles L. Raison Psychological Medicine, 2020, 1–12. doi : 10.1017/S003329172000389X   Abstract Background. 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 [...]

Development of Ketamine Administration as a Treatment for Chronic PTSD, Abigail B. Collins et al., 2020

Development of Ketamine Administration as a Treatment for Chronic PTSD Abigail B. Collins, BS; Sarah B. Rutter, MA; and Adriana Feder, MD Psychiatric Annals, 2020, 50, (2), 68-76. doi : 10.3928/00485713-20200109-01   ABSTRACT Posttraumatic stress disorder (PTSD) is a highly prevalent, chronic, and dis-abling condition for which currently available pharmacotherapies are insuf-ficiently effective. Ketamine, which is a glutamate N-methyl-D-aspartate (NMDA) receptor antagonist, has emerged as a promising and rapid-act-ing novel treatment intervention for this disorder. Findings from a proof-of-concept, randomized, controlled cross-over study of single-dose intravenous ketamine administration (compared to single-dose midazolam) in patients with chronic PTSD suggest that ketamine is associated with rapid improvement in [...]

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

Psilocybin Delivers 'Remarkable' Relief in Severe Depression Batya Swift Yasgur, MA, LSW Medscape.com, 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 and really sets the [...]

Effects of Psilocybin-Assisted Therapy on Major Depressive Disorder. A Randomized Clinical Trial Alan K. Davis, PhD; Frederick S. Barrett, PhD; Darrick G. May, MD; Mary P. Cosimano, MSW; Nathan D. Sepeda, BS; Matthew W. Johnson, PhD; Patrick H. Finan, PhD; Roland R. Griffiths, PhD JAMA Psychiatry, 2020, E1-E9. doi : 10.1001/jamapsychiatry.2020.3285   IMPORTANCE : Major depressive disorder (MDD) is a substantial public health burden, but current treatments have limited effectiveness and adherence. Recent evidence suggests that 1 or 2 administrations of psilocybin with psychological support produces antidepressant effects in patients with cancer and in those with treatment-resistant depression. OBJECTIVE : To investigate the effect of psilocybin [...]

Psychedelics as a Treatment for Alzheimer’s Disease Dementia, Simon Andrew Vann Jones and Allison O’Kelly, 2020

Psychedelics as a Treatment for Alzheimer’s Disease Dementia Simon Andrew Vann Jones and Allison O’Kelly Cornwall Partnership NHS Foundation Trust, Liskeard, United Kingdom Frontiers in Synaptic Neuroscience, August 2020 | Volume 12 | Article 34 doi : 10.3389/fnsyn.2020.00034   Currently, there are no disease-modifying treatments for Alzheimer’s disease (AD) or any other dementia subtype. The renaissance in psychedelic research in recent years, in particular studies involving psilocybin and lysergic acid diethylamide (LSD), coupled with anecdotal reports of cognitive benefits from micro-dosing, suggests that they may have a therapeutic role in a range of psychiatric and neurological conditions due to their potential to stimulate neurogenesis, provoke neuroplastic [...]
