Treatment options for gambling disorder (GD) remain limited, with no pharmacotherapy proven effective. As of date, cognitive behavioral therapy (CBT) is the preferred therapy for GD, but the improvements often require months to show, highlighting the need for a more comprehensive therapy. Repetitive transcranial magnetic stimulation (rTMS) is a promising treatment modality in alleviating craving. Studies have shown potential benefit of combining both CBT and rTMS in substance addiction, but not in GD. Thus, this study aims to determine the feasibility and efficacy of rTMS and CBT combination therapy in the management of GD in Indonesia.
