Clinical Trial Summary

The investigators assume that transcranial Alternating Current Stimulation (tACS) could improve gambling disorder patients' executive-control function by adjusting the synchronization patterns and enhancing the functional connectivity of the prefrontal-ventral striatum pathway. This study intends to test the effect of tACS treatment. Three-month follow-up assessment will be conducted to test the changing of the executive-control function and its mechanism.


Clinical Trial Description

Gambling disorder is become a major social and public health problem in China. Executive-control dysfunction is the main symptom of behavioral addiction like gambling disorder. Previous studies have demonstrated the relationship between cognitive dysfunction and prefrontal-ventral striatum pathway. Studies have shown that abnormal phase synchronization and phase-amplitude coupling (PAC) induced the impairment of cognition, and transcranial Alternating Current Stimulation (tACS) could improve executive-control function by adjusting the abnormal synchronization. However, it has not been verified among gambling disorder patients. The investigators assume that tACS could improve gambling disorder patients' executive-control function by adjusting the synchronization patterns and enhancing the functional connectivity of the prefrontal-ventral striatum pathway. This study intends to test the effect of tACS treatment. Three-month follow-up assessment will be conducted to test the changing of the executive-control function and its mechanism. This study will provide a practical and theoretical basis for developing a novel treatment for gambling disorder. ;
