Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation technique that has been assessed in a growing number of studies for its therapeutic potential in treating addiction. This review paper offers an overview on the current state of clinical research in treating drug addiction with rTMS. Because of the limited research in this area, all studies (including case reports) that evaluated the therapeutic use of rTMS in nicotine, alcohol, or illicit drug addiction were included in this review. Papers published prior to December 2012 were found through an NCBI PubMed search. A total of eleven studies were identified that met review criteria. There is nascent evidence that rTMS could be effective in reducing cocaine craving and nicotine and alcohol craving and consumption and might represent a potential therapeutic tool for treating addiction. Further studies are needed to identify the optimal parameters of stimulation for the most effective treatment of drug addiction, to improve our comprehension of the treatment neurophysiological effects, and to conduct rigorous, controlled efficacy studies with adequate power. 1. Introduction Psychoactive drugs act on the central nervous system and recurring drug intoxication can result in addiction, a complex disease process of the brain which can be treated [1]. Addiction can be described as a persistent state in which there is reduced capacity to control compulsive drug-seeking, regardless of whether it involves risk of negative consequences [2, 3]. It is often a devastating and chronically relapsing disorder with social, psychological, and physical consequences. Drug addiction incurs enormous medical, economic, and social costs. The currently available treatment options for addiction remain somewhat limited and long-term success rates are modest [4]. Brain stimulation allows modulation of activity in specific brain regions. Recently, nonsurgical brain stimulation techniques have been utilized in examining the effects of drug administration on cortical activity in order to further explore the effects of repeated drug use on cortical excitability. Furthermore, several novel studies have begun to assess brain stimulation as a potential treatment for reducing addictive behaviours [5].
