The P300 component was notably enhanced in IGD during cue exposure, indicating new EEG markers for diagnosis.
Analysis of 25 IGD, 22 recreational gamers, and 18 healthy controls produced an AUC greater than 0.8 for distinguishing IGD with machine learning.
tDCS targeting the P300 component led to significantly lower craving levels in IGD, maintaining effects up to four weeks post-intervention.
The findings highlight the potential of EEG markers and tDCS as effective tools for diagnosing and treating internet gaming disorder.
