OBJECTIVES The aim of this study was to evaluate the altered brain structure and functional connectivity (FC) among subjects with Internet gaming disorder (IGD). METHODS We recruited 30 males with IGD and 30 controls and evaluated their gray matter density (GMD) and FC using resting fMRI. The severities of IGD, gaming urge, and impulsivity were also assessed. RESULTS The results demonstrated that the subjects with IGD had a higher impulsivity and a greater severity of IGD. The subjects with… CONTINUE READING
