The Effectiveness of tDCS on Internet Game Addiction

Randomized Double-blind Clinical Trial to Evaluate the Effectiveness of Transcranial Direct Current Stimulation (tDCS) on Internet Game Addiction

In this study, the investigators aimed to investigate the effect of transcranial direct current stimulation (tDCS) on clinical status of Internet game addiction. The clinical status of Internet game addiction includes severity of addiction symptom, subjective craving for gaming, response inhibition and cue reactivity. The investigators hypothesized that real stimulation with tDCS on the dorsolateral prefrontal cortex will have higher effectiveness on severity of addiction symptom, subjective craving for gaming, response inhibition and cue reactivity rather than sham stimulation with tDCS.

Inclusion Criteria:
