Abstract
Internet Gaming Disorder (IGD) is a potential mental disorder currently included in the
third section of the latest (fifth) edition of the Diagnostic and Statistical Manual for Mental
Disorders (DSM-5) as a condition that requires additional research to be included in the
main manual. Although research efforts in the area have increased, there is a continuing
debate about the respective criteria to use as well as the status of the condition as mental
health concern. Rather than using diagnostic criteria which are based on subjective
symptom experience, the National Institute of Mental Health advocates the use of
Research Domain Criteria (RDoC) which may support classifying mental disorders based
on dimensions of observable behavior and neurobiological measures because mental
disorders are viewed as biological disorders that involve brain circuits that implicate
specific domains of cognition, emotion, and behavior. Consequently, IGD should be
classified on its underlying neurobiology, as well as its subjective symptom experience.
Therefore, the aim of this paper is to review the neurobiological correlates involved in
IGD based on the current literature base. Altogether, 853 studies on the neurobiological
correlates were identified on ProQuest (in the following scholarly databases: ProQuest
Psychology Journals, PsycARTICLES, PsycINFO, Applied Social Sciences Index and
Abstracts, and ERIC) and on MEDLINE, with the application of the exclusion criteria
resulting in reviewing a total of 27 studies, using fMRI, rsfMRI, VBM, PET, and EEG
methods. The results indicate there are significant neurobiological differences between
healthy controls and individuals with IGD. The included studies suggest that compared to
healthy controls, gaming addicts have poorer response-inhibition and emotion regulation,
impaired prefrontal cortex (PFC) functioning and cognitive control, poorer working
memory and decision-making capabilities, decreased visual and auditory functioning,
and a deficiency in their neuronal reward system, similar to those found in individuals
with substance-related addictions. This suggests both substance-related addictions
and behavioral addictions share common predisposing factors and may be part of an
addiction syndrome. Future research should focus on replicating the reported findings
in different cultural contexts, in support of a neurobiological basis of classifying IGD and
related disorders.
