Overview
Brief Summary
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.

Time Frame: 25 week
The Y-IAT is rated on a five-point scale. Total scores for all 20 items range from 20 to 100.
Secondary Outcomes
- Direction error and successful stop ratio in the Stop signal task(baseline, 5 weeks, 25 weeks)
- Barratt impulsiveness scale-11(baseline, 5 weeks, 25 weeks)
- Anti-saccade error rate in the attentional bias task(baseline, 5 weeks, 25 weeks)
- Late positive potential in the cue reactivity event-related potential(baseline, 5 weeks, 25 weeks)
- Visual analogue scale(baseline, 1 week, 5 weeks, 25 weeks)
