Standard treatments frequently demonstrate limited efficacy, leading to persistent symptoms and high dropout rates. Psilocybin has shown promise in treating depression, a condition that is often comorbid with PTSD. We aimed to explore participant experiences of psilocybin...

Patients with treatment resistant depression (TRD) experience a greater negative impact on their functioning and productivity at home and in the workplace versus treatment-responsive patients. Here, we report the effects of esketamine nasal spray (NS) versus quetiapine extended release (XR) on functioning, work productivity and activity impairment. ESCAPE‑TRD (NCT04338321) was a 32-week...

Background: Psychedelics such as psilocybin, lysergic acid diethylamide, and 3,4-methylenedioxymethamphetamine are increasingly recognized for their potential therapeutic benefits in treating complex and chronic mental health conditions. Growing public interest in psychedelics may drive increased consumption outside of medically supervised clinical trials. Correspondingly, legality issues and...

In psychedelic therapy, mystical as well as challenging experience may influence therapeutic outcome. However, predictors of such experience have not been sufficiently established. Determining predictors of their intensity is, therefore, potentially beneficial in targeting psilocybin therapy for depression. In a post hoc data analysis of a Phase 1, randomised, double-blind, placebo-controlled,...

Most interventions for treatment-resistant depression (TRD) are added as augmenters. We aimed to determine the relative effectiveness of augmentation treatments for TRD. This systematic review and network meta-analysis (NMA) sought all randomized trials of pharmacological and psychological augmentation interventions for adults meeting the most common clinical criteria for TRD. The NMA compared...
