Ketamine for Depression Faces Its Biggest Test Yet John Watson https://www.medscape.com/viewarticle/910994?nlid=129178_425&src=WNL_mdplsfeat_190409_mscpedit_psyc&uac=292598PZ&spon=12&impID=1932155&faf=1 April 04, 2019 One of the more unexpected stories from this past decade of psychiatric research has been the journey of ketamine from illicit drug to a promising therapy for treatment-resistant depression. Yet, even as its reputation has been burnished by accounts of patients experiencing dramatic responses to short-term therapy, ketamine was noticeably lacking in large-scale trials necessary to shift it further still, from an experimental treatment to an established intervention. In 2017, investigators sought to address this gap by initiating the ELEctroconvulsive therapy (ECT) vs. Ketamine in patients with Treatment-resistant Depression (ELEKT-D) trial.[1] Sponsored by [...]

However, for some experts, this excitement only serves to heighten concerns about the many unknowns and potential long-term side effects of the drug, which began its long history as an anesthetic. Here, at the Anxiety and Depression Association of American (ADAA) 2019 Conference, experts debated the drug's merits and potential pitfalls. "These are exciting times and I think ketamine has opened a new era," Carlos [...]

Abstract : LSD is one of the most potent psychoactive agents known, producing dramatic alterations of consciousness after submilligram (≥20 g) oral doses. Following the accidental discovery of its potent psychoactive effects in 1943, it was supplied by Sandoz Laboratories as an experimental drug that might be useful as an adjunct for psychotherapy, or to give psychiatrists insight into the mental processes in their patients. The finding of serotonin in the mammalian brain in 1953, and its structural resemblance to LSD, quickly led [...]

DOI 10.3917/psyt.233.0125 https://www.cairn.info/revue-psychotropes-2017-3-page-125.htm Résumé : L’utilisation thérapeutique des substances psychédéliques a été concomitante de la découverte du LSD et de la Mescaline après la Seconde Guerre mondiale. Ces utilisations thérapeutiques concernaient, à l’origine, essentiellement « l’accompagnement » des psychothérapies (thérapies psycholytiques), le traitement des addictions (alcool, puis opiacés) et, du fait de leurs capacités anxiolytiques et antidépressives, la prise en charge des troubles psychologiques post-traumatiques, les dépressions résistantes, les pathologies obsessionnelles et psychosomatiques (douleurs, migraines…) et l’accompagnement des fins [...]

Lire la suitePsilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer : A randomized double-blind trial GRIFFITHS R.R., JOHNSON M.W., CARDUCCI M.A., UMBRICHT A., RICHARDS W.A., RICHARDS B.D., COSIMANO M.P., KLINEDINST M.A. Journal of Psychopharmacology, 2016, 30, 12, 1181–1197. DOI: 10.1177/0269881116675513 jop.sagepub.com Abstract Cancer patients often develop chronic, clinically significant symptoms of depression and anxiety. Previous studies suggest that psilocybin may decrease depression and anxiety in cancer patients. The effects of psilocybin were studied in 51 cancer patients with life-threatening diagnoses and symptoms of depression and/or anxiety. This randomized, double-blind, cross-over trial investigated the effects of a very low (placebo-like) dose [...]

Doi : 10.1177/0269881117748902 journals.sagepub.com/home/jop Abstract Rationale : Previous research suggests that classical psychedelic compounds can induce lasting changes in personality traits, attitudes and beliefs in both healthy subjects and patient populations. Aim : Here we sought to investigate the effects of psilocybin on nature relatedness and libertarian authoritarian political perspective in patients with treatment-resistant depression (TRD). Methods : This open-label pilot study with a mixed-model design studied the effects of psilocybin on measures of nature relatedness and libertarian– authoritarian political perspective in patients with [...]
