What this trial studies

This clinical trial investigates the effectiveness of individualized intermittent Theta Burst Stimulation (iTBS) for patients with treatment-resistant depression (TRD). It involves a randomized, double-blinded design with three treatment arms: fully individualized iTBS, targeted iTBS, and standard iTBS. Over 20 sessions in four weeks, the study will assess changes in brain connectivity and clinical depression severity using EEG and standardized rating scales. The goal is to determine if the individualized approach leads to better outcomes compared to standard treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 with a diagnosis of major depressive disorder who have not responded to at least one antidepressant medication.

Not a fit: Patients with active psychotic symptoms, neurological disorders, or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from treatment-resistant depression.

How similar studies have performed: Other studies have shown promise with similar approaches to individualized brain stimulation, suggesting potential for success in this trial.
