Purpose of Review
This narrative review is aimed at summarizing the scientific evidence suggesting that the core psychological and neurobiological mechanisms underlying substance use disorders and gambling disorder are also involved in gaming disorder.
Theoretical models that aim to explain the development and maintenance of gaming disorder focus on cue reactivity and craving as well as on reduced inhibitory control processes and dysfunctional decision-making as core processes underlying symptoms of gaming disorder. The empirical evidence, including studies and meta-analyses with patients with gaming disorder and both nongamers and recreational gamers as control subjects, emphasizes the relevance of these theoretically argued core processes in gaming disorder.
Scientific evidence suggests that the core mechanisms underlying substance use disorders and gambling disorder are also involved in gaming disorder. Inclusion of gaming disorder in ICD-11 as a disorder due to addictive behaviors, along with gambling disorder, is justified.
