Abstract

A significant reduction in depressive symptoms was observed at 3 weeks post-treatment, with a MADRS score change of -15.8.

  • Twelve participants with severe treatment-resistant depression were monitored over a 12-week period.
  • Depressive symptoms continued to decrease at week 12, with a MADRS score change of -17.2.
  • Exploratory analyses indicated a correlation between the Oceanic Boundlessness dimension of the psychedelic experience and post-dosing antidepressant responses.
  • Patients with comorbid PTSD showed significantly less antidepressant effect from psilocybin.
