Risk classification of internet gaming disorder based on neurobiological subtyping from impulsivity-linked resting-state functional connectivity: a longitudinal design study

Impulsivity-related RSFC identified a youth subtype at elevated risk for developing IGD. This high-risk subtype showed a higher future IGD conversion rate, greater subsequent increases in IGD severity, and a baseline orbitofrontal-occipital connectivity imbalance. These findings suggest that an orbitofrontal-occipital circuit imbalance may serve as a potential marker for identifying IGD risk in youth.
