Psilocybin Therapy for Treatment Resistant Depression: Prediction of Clinical Outcome by Natural Language ProcessingThis article of a language model (NLP, BART) finds that the audio from psychological support sessions (in the COMP360 trial for treatment-resistant depression, n=90 at 12 weeks) can predict clinical outcomes with high (85%) accuracy. The implications of this research signal that audio recordings can be used to predict who will respond to treatment and possibly aid in helping identify who would need more support.
Patient perspectives and experiences with psilocybin treatment for treatment-resistant depression: a qualitative study
This qualitative study (n=11) explores the experiences of treatment-resistant depression (TRD) patients undergoing a double-blind, randomized clinical trial with a single session of oral psilocybin treatment (1, 10, or 25 mg). Three major themes emerged: trust-building and expectation management challenges, navigating the experience, and the need for a more comprehensive treatment. Subthemes included distrust in mental healthcare, managing expectations, profound experiences during the session, and a desire for multiple psilocybin sessions. Insights from patients' perspectives suggest strategies for optimizing psilocybin treatment for TRD, such as individualized preparation, trust-building, additional sessions, and personalized therapy approaches.
The Impact of Antidepressant Discontinuation Prior to Treatment with Psilocybin for Treatment-Resistant Depression
This post hoc analysis (n=233) of a Phase II RCT investigates the impact of recent antidepressant discontinuation (n=156) on the efficacy of psilocybin in treating treatment-resistant depression (TRD). The study compares outcomes between participants who discontinued antidepressants during screening and those who entered the trial free of these medications, finding no significant relationship between antidepressant discontinuation and worsening depression severity or compromised psilocybin treatment efficacy.
