Probably not a fit

Patients with psychosis, severe head trauma, or significant somatic diseases may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The BrainDrugs-D study focuses on patients with major depressive disorder (MDD) by utilizing multimodal neuroimaging techniques alongside self-report measures and clinical data to identify subtypes of MDD and predict treatment responses. Participants will undergo a thorough phenotyping process before receiving a standardized treatment package that includes cognitive-behavioral therapy and medication management. The study aims to recruit 800 patients and will follow them in nationwide health registries to assess treatment outcomes in a naturalistic setting.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatment strategies for individuals suffering from major depressive disorder.

How similar studies have gone: Other studies utilizing neuroimaging to predict treatment response in depression have shown promise, indicating that this approach is both relevant and potentially impactful.
