Future Directions for Clinical Psychedelic Research : The Relaxed Symptom Network, Evan Lewis-Healey et al., 2021

Future Directions for Clinical Psychedelic Research : The Relaxed Symptom Network Evan Lewis-Healey, Ruben Laukkonen , Michiel van Elk Pre-Print, May 2021 Doi : 10.31234/osf.io/q3ymd Abstract Recent clinical trials have demonstrated that psilocybin may have strong antidepressant effects, and may be effective in the treatment of depressive disorders when embedded in a psychotherapeutic protocol (psychedelic-assisted psychotherapy; PAP). There are now dozens of registered and ongoing clinical trials that intend to test for the efficacy of psilocybin within a psychotherapeutic protocol. Despite promising results, the mechanism(s) that may be responsible for the antidepressant effects of PAP are still hotly contested. In this paper, we provide a [...]

Cannabidiol as a Therapeutic Alternative for Post-traumatic Stress Disorder : From Bench Research to Confirmation in Human Trials Rafael M. Bitencourt and Reinaldo N. Takahashi Frontiers in Neuroscience, 2018, 12, 502, 1-10. Doi : 10.3389/fnins.2018.00502   Post-traumatic stress disorder (PTSD) is characterized by poor adaptation to a traumatic experience. This disorder affects approximately 10% of people at some point in life. Current pharmacological therapies for PTSD have been shown to be inefficient and produce considerable side effects. Since the discovery of the involvement of the endocannabinoid (eCB) system in emotional memory processing, pharmacological manipulation of eCB signaling has become a therapeutic possibility for the treatment of [...]
