Summary

This study tests whether a mild electrical current applied to the scalp (tDCS) can reduce the urge to play internet games in people with pathological gaming disorder. Fifty participants will receive either real or fake stimulation over five sessions. Researchers will measure changes in gaming behavior and impulsivity four weeks after treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS)
What this could lead to
If it works, this could point toward a non-drug treatment for internet gaming addiction, helping people regain control over their gaming habits.
What could go wrong
This is a small, early pilot study with only 50 participants, so results may not apply widely. The effect may be small or temporary, and the treatment requires multiple sessions.
