Internet Gaming Disorder

초록

Internet games are receiving considerable attention due to their multifaceted nature including recreational applications, improved graphics, early clinical applications, and concerns regarding clinical side effects due to excessive play. This chapter reviews the results of functional and structural brain changes, neurophysiological responses, and biogenetic traits in individuals with Internet gaming disorder (IGD). IGD and substance addiction appear to share common activated brain regions including corticostriatal tracts in response to game or substance cues. In addition, neurophysiological responses such as poor error processing as well as association with dopamine and serotonin have been observed in both impulse control disorder and behavioral addictions. However, the use of inconsistent diagnostic criteria across studies, variable demographic characteristics, high rates of psychiatric comorbidity, and uncertain courses of disease require further research. © 2016 Elsevier Inc.
