ABSTRACT

Objective:To explore the effect of repeated high-frequency transcranial magnetic stimulation over the left dorsolateral prefrontal cortex (DLPFC) on the severity and symptoms of Internet addiction.Methods:Fifty college students with different degrees of Internet addiction were randomly divided into a treatment group and a control group, each of 25. In addition to psycho-behavioral therapy, the treatment group was given 10Hz rTMS over the left DLPFC for 40 days, while the control group was given sham stimulation. Before the experiment and after 4 and 8 weeks of treatment, both groups were evaluated using the Internet Addiction Diagnostic Scale (IAT), Barratt Impulsiveness Scale (BIS-11) and a visual analogue scale (VAS).Results:After 4 weeks the average total BIS-11 score, attention factor score and VAS score of the treatment group were significantly better than the control group′s averages and better than before the treatment. After 8 weeks of treatment, the average IAT scores, BIS-11 scores on each item and VAS scores of the treatment group had decreased significantly more and were still significantly better than the control group′s averages.Conclusion:High frequency rTMS can safely and effectively relieve the symptoms of Internet addiction, at least among college students.
