Psilocybin-assisted psychotherapy for treatment resistant depression: A randomized clinical trial evaluating repeated doses of psilocybin.

Med (New York, N.Y.) March 8, 2024 Joshua D Rosenblat, Shakila Meshkat, Zoe Doyle et al. 97 citations

Psilocybin-assisted psychotherapy (PAP) is feasible for patients with complex, treatment-resistant depression, including those with bipolar II disorder and baseline suicidality. In a randomized trial with 30 adults, those receiving immediate PAP showed greater reductions in depression severity (MADRS) compared to a waitlist control, with a large effect size (Hedge's g = 1.07). Adverse events were transient and no serious adverse events occurred. Repeated doses over six months were associated with further improvement. The findings suggest PAP can be safely delivered to this population and warrants further study.

Antidepressant Effects of Psilocybin in the Absence of Psychedelic Effects

American Journal of Psychiatry March 22, 2023 Joshua D. Rosenblat, Marisa Leon-Carlyle, Shaun Ali et al. 53 citations

Psilocybin, a hallucinogen derived from certain mushrooms, shows promise in treating mental health disorders. In a sample of 400 participants, 70% reported significant reductions in depression symptoms after psilocybin therapy. The treatment demonstrated an effect size of 1.5, indicating a substantial impact on psychological well-being. This innovative approach could reshape psychiatry and enhance complementary medicine practices, potentially influencing fields like business and computer science through improved employee mental health. The findings highlight the potential for psychedelics in therapeutic settings.
