تأثیر تحریک مکرر مغناطیسی از روی جمجمه (rTMS) بر میزان ولع مصرف مواد معتادان مصرف کننده مت آمفتامین (MA)

Background and purpose: Met amphetamine is a very strong stimulant which intensively influences the central nervous system. Many researches have established the significance of experiencing consumption desire in addiction. This study aimed at assessing the effect of repeated magnetic stimulus from skull (rTMS) on decrease of desire of drug abuse in addicts to metamphetamine (MA). Materials and methods: In this study, a semi-experimental design with a 'pretest'- 'posttest' control group was used. The samples included 20 subjects with the desire to abuse MA in spring and summer of 2011. Based on available sampling method the cases were placed under the stimulus of repeated transcranial magnetic stimulation (rTMS) on pre forehead of right hemisphere (frequency of 10 Hrz) and left hemisphere (frequency of 1 Hrz) for 20 sessions (30 minutes). The subjects were evaluated using the desire for drug questionnaire (DDQ) before initiating treatment, by the end of 20th session and 1.5 month after treatment. The data was then analyzed using covariance analysis in SPSS. Results: rTMS significantly decreased the desire to abuse drug in addicts to MA which continued until 1.5 month after treatment. Conclusion: Findings showed the effective influence of rTMS on reducing the desire for drug abuse, so it is suggested as a useful approach for treatment programs of drug abusers.
