This article highlights current research on gaming disorder (GD), focusing primarily on neuropsychological features. Advances in digital technology have made gaming more accessible, realistic, and competitive than ever before, leading to a rise in GD prevalence. Pathological gaming is frequently associated with poor inhibitory processing, decision-making, self-control, as well as exaggerated automatic, attentional, and emotional processing of gaming-related cues. Many of the core cognitive features of GD, including executive function (EF) dysfunction, associated deficits in cognitive flexibility, empathy, and social skills, are also observed in other addictions as well as seemingly unrelated psychiatric disorders such as autism spectrum disorder. Accordingly, recent brain-imaging studies of these disorders have repeatedly reported abnormal EF concomitant with altered activity in frontal regions subserving reward processing and self-control. These neuropsychological features may provide important clues to GD pathogenesis and improved clinical intervention.
