What this trial studies

This study is testing a novel treatment called image-guided, robot navigated transcranial magnetic stimulation (IR-TMS) to help individuals with alcohol use disorder (AUD) reduce their drinking. Participants will be randomly assigned to one of three treatment groups, each targeting different areas of the brain based on personalized fMRI connectivity maps. The treatment involves multiple sessions of IR-TMS, along with brain scans and assessments of drinking behavior and mental health. The goal is to evaluate the effectiveness and durability of this innovative approach compared to traditional therapies.

Who should consider this trial

Good fit: Ideal candidates are individuals with moderate to severe alcohol use disorder who have experienced heavy drinking episodes.

Not a fit: Patients with other substance use disorders, severe psychiatric conditions, or those currently undergoing AUD treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new, effective option for individuals struggling with alcohol use disorder.

How similar studies have performed: While this approach is innovative, similar studies using transcranial magnetic stimulation have shown promise in treating various conditions, suggesting potential for success.
