Brief Summary: The investigators assume that tACS could improve amphetamine and alcohol dependent patients' executive-control function by adjusting the synchronization patterns and enhancing the functional connectivity of the prefrontal-ventral striatum pathway. A random controlled trial will be used to test the effect of θ-tACS treatment. Three months follow-up assessment will be conducted to test the changing of executive-control function and its mechanism.
Detailed Description: Substance abuse has become a major social and public health problem in China, especially for amphetamine abuse and alcohol abuse. Executive-control dysfunction is the main symptom for substance dependents. 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 cognitive, and tACS could improve executive-control function by adjusting the abnormal synchronization. But it has not been verified among MA or alcohol patients. The investigators assume that tACS could improve MA and alcohol dependent patients' executive-control function by adjusting the synchronization patterns and enhancing the functional connectivity of the prefrontal-ventral striatum pathway. A random controlled trial will be used to test the effect of θ-tACS treatment. Three months follow-up assessment will be conducted to test the changing of executive-control function and its mechanism. This study will provide a practical and theoretical basis for developing a novel treatment for substance dependents.
