مروری برمطالعه اثربخشی تحریک فراجمجه ای مغز با جریان مستقیم (tDCS) در اختلالات مصرف مواد

Objective: Transcranial direct current stimulation (tDCS) has recently applied as a technique in the domain of drug use disorders. In this paper, we reviewed the articles and studies carried out in this field in order to examine the issues pertaining to the methodology, its application, and its effectiveness in the area of drug use disorders. Method: The number of 24 papers was selected out of 60 available papers. Among them, 22 studies had examined the effect of tDCS prefrontal cortex and 3 studies had investigated the effectiveness of tDCS in reducing drug use craving. Results: It is not still possible to argue for the effectiveness of tDCS as a very effective treatment for reducing drug use craving. Conclusion: Small sample sizes, different protocols, duration of the study, and lack of any follow-ups were among the main limitation of these studies; however, it can be used as a complementary treatment.
