Diverses études et rapports d’expérience indiquent que le cannabinoïde non-psychoactif cannabidiol (CBD) peut soulager leurs symptômes.

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.
