What this trial studies

This study aims to create personalized brain signatures for individuals experiencing negative emotions such as rumination, major depressive disorder, and anxiety. Participants will undergo a series of MRI scans and assessments to identify their unique negative affect patterns. Following this, they will receive tailored repetitive transcranial magnetic stimulation (rTMS) sessions designed to disrupt these negative patterns. The study involves multiple visits, including behavioral tasks and assessments to evaluate the effectiveness of the stimulation protocols.

Who should consider this trial

Good fit: Ideal candidates are right-handed adults aged 18-65 with a PHQ-9 score of 10 or higher, indicating moderate to severe depression.

Not a fit: Patients with bipolar disorder, schizophrenia, or those who cannot tolerate TMS or MRI scans may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective treatments for individuals suffering from depression and anxiety by personalizing brain stimulation techniques.

How similar studies have performed: While the use of rTMS has been explored in other studies, this personalized approach using fMRI to tailor stimulation protocols is relatively novel.
