Themesocorticolimbic dopaminergic reward system seems to play a crucial role in inducing depression andanxiety in methamphetamine users. High-frequency repetitive transcranial magnetic stimulation (rTMS) hasbeen shown to alter dopaminergic neurotransmission considering the acute rewarding and reinforcing effectsin the subcortical structure. The aim of this study was to investigate the efficacy of rTMS in reducingdepression and anxiety symptoms in methamphetamine users.Methods: In a single-subject method with concurrent multiple baseline designs, in 2017, in Iran, eightmethamphetamine users were included, which compared 15 days of active versus placebo stimulation andcontrol group. Two subjects received rTMS on the right dorsolateral prefrontal cortex (DLPFC) and twosubjects received rTMS on the left DLPFC. We carried out the measurement using the Beck Anxiety Inventory(BAI) and Beck Depression Inventory (BDI) before, during, and after 15 and 30 days of the procedure.Findings: Right and left DLPFC stimulation significantly reduced depression and anxiety, but the reductionof depression and anxiety by the right DLPFC stimulation was noticeable in this study.Conclusion: High-frequency rTMS is useful for the treatment of depression and anxiety in methamphetamineusers}, keywords = {Transcranial magnetic stimulation,depression,Anxiety,Methamphetamine}, url = {https://ahj.kmu.ac.ir/article_91553.html}, eprint = {https://ahj.kmu.ac.ir/article_91553_783a04c13b82b26f66fa6bfecdcd8fbf.pdf} }
