High‐intensity transcranial alternating current stimulation for gambling disorder comorbidities with alcohol use disorders: A case report

Abstract Background and Objectives Gambling and alcohol use disorders are highly comorbid. We investigated the safety and efficacy of high‐intensity transcranial alternating current stimulation (HI‐tACS) for this dual diagnosis. Methods This case report presents a 33‐year‐old female with GD‐AUD who received HI‐tACS (15 mA, 77.5 Hz, 20 sessions). Results Posttreatment, inhibitory control improved. At the 3‐month follow‐up, the patient maintained complete abstinence from both gambling and alcohol. The intervention was well‐tolerated. Discussion and Conclusions HI‐tACS is a safe, efficacious potential treatment for GD‐AUD comorbidity. Scientific Significance This first application of HI‐tACS for GD‐AUD comorbidity provides preliminary evidence, warranting larger controlled trials.
