What this trial studies

This study investigates the impact of repetitive Transcranial Magnetic Stimulation (rTMS) on chronic pain symptoms in individuals with Major Depressive Disorder (MDD). A total of 54 participants will undergo 30 treatments of rTMS, alongside various assessments including surveys, blood draws, MRIs, and electroencephalograms. The study aims to understand the neuro-immune interactions that contribute to both chronic pain and depression, particularly in treatment-resistant cases. All participants will receive active treatment, with no control group involved.

Who should consider this trial

Good fit: Ideal candidates are right-handed adults aged 18-75 with moderate Major Depressive Disorder and chronic pain who have not responded to multiple antidepressant treatments.

Not a fit: Patients who do not have a confirmed diagnosis of Major Depressive Disorder or chronic pain, or who have not failed multiple treatment trials, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel therapeutic approach for alleviating chronic pain in patients suffering from Major Depressive Disorder.

How similar studies have performed: Other studies have shown promising results with rTMS for depression, but this specific approach targeting chronic pain in MDD is relatively novel.
