What this trial studies

This clinical trial investigates the effects of theta burst stimulation on patients diagnosed with Gambling Disorder. In a randomized double-blind placebo-controlled design, 40 participants will receive either active or sham transcranial magnetic stimulation (TMS) to the pre-supplementary motor area (pre-SMA) over two weeks. The study aims to explore the neural mechanisms underlying gambling behavior by combining TMS with multimodal structural and functional MRI, as well as behavioral assessments. The goal is to identify changes in brain connectivity that correlate with clinical improvements in inhibitory control and symptom severity.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with a DSM-5 diagnosis of Gambling Disorder.

Not a fit: Patients with significant psychiatric comorbidities or a history of severe mental disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance inhibitory control and reduce gambling impulses in affected individuals.

How similar studies have performed: Previous studies using TMS for various psychiatric conditions have shown promising results, suggesting potential efficacy for this novel application in Gambling Disorder.
