François-Olivier GAGNON-HÉBERT – Chercheur Postdoctoral/ Université de Moncton, Canada La Lettre du RESPADD, 2019, 36, 4-5 https://www.respadd.org/lettre-n36-octobre-2019/ Il semble y avoir une véritable résurgence du cannabis dans les débats publics à l’échelle internationale depuis quelques années.

Lire la suitePsilocybin-Assisted Therapy : A Review of a Novel Treatment for Psychiatric Disorders Kelan Thomas, Pharm.D., M.S., Benjamin Malcolm, Pharm.D., M.P.H., and Dan Lastra, B.S. Journal of Psychoactive Drugs, 2017 Doi : 10.1080/02791072.2017.1320734 Abstract Recent research suggests that functional connectivity changes may be involved in the pathophysiology of psychiatric disorders. Hyperconnectivity in the default mode network has been associated with psycho-pathology, but psychedelic serotonin agonists like psilocybin may profoundly disrupt these dysfunctional neural network circuits and provide a novel treatment for psychiatric disorders. We have reviewed the current literature to investigate the efficacy and safety of psilocybin-assisted therapy for the treatment of psychiatric disorders. There were [...]
