What this trial studies

This clinical trial investigates the effectiveness of intermittent theta-burst transcranial magnetic stimulation (iTBS-TMS) applied to the inferior parietal lobule in patients diagnosed with major depressive episode or borderline personality disorder who exhibit suicidal thoughts and behaviors. The study aims to identify the brain circuit properties associated with suicidal risk and to determine biological predictors of response to the treatment. Participants will receive either active or sham stimulation while their brain activity is monitored through neuroimaging techniques.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-65 diagnosed with major depressive episode or borderline personality disorder who are experiencing suicidal thoughts and behaviors.

Not a fit: Patients with neurological conditions, severe psychopathology not suitable for treatment, or those with contraindications for MRI scanning may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce suicide risk in patients suffering from major depressive episode or borderline personality disorder.

How similar studies have performed: Other studies have shown promise with similar brain stimulation techniques, suggesting potential for success in this novel application.
