Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Participants Investigators

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

tDCS with real stimulation

A total of 25 patients will be allocated into active comparator with real stimulation with tDCS.

Group Type ACTIVE_COMPARATOR

tDCS with real stimulation

Intervention Type DEVICE

tDCS is a non-invasive brain stimulation. Real stimulation includes 2mA current for 20 minutes per session. Two sessions a day for 5 consecutive days (Total: 10 sessions) will be applied.

tDCS with sham stimulation

A total of 25 patients will be allocated into sham comparator with sham stimulation with tDCS.

Group Type SHAM_COMPARATOR

tDCS with sham stimulation

Intervention Type DEVICE

Sham stimulation includes 0mA current for 20 minutes per session. Two sessions a day for 5 consecutive days (Total: 10 sessions) will be applied.
