Troubles anxieux : le CBD peut soulager les symptômes Kalapa Clinic, Barcelone, Espagne By Gesa|30/06/2020   La peur est une réaction naturelle à certaines situations et à certains événements. Elle remplit à la fois une fonction d’avertissement et de protection. Lors d’un trouble anxieux, cependant, elle développe une dynamique propre qui est très stressante pour les personnes concernées. Diverses études et rapports d’expérience indiquent que le cannabinoïde non-psychoactif cannabidiol (CBD) peut soulager leurs symptômes. En Allemagne, le trouble anxieux est la maladie mentale la plus courante, devançant même la dépression. Environ 12 millions de personnes sont touchées, les femmes plus souvent que les hommes (1).

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 [...]
