“…For example, Choi et al . found that individuals with an Internet addiction show decreased beta and increased gamma absolute power values 46 , which indicates that the functionality of the DMN may be altered in patients with Internet addictions.…”

The present study compared neural connectivity and the level of phasic synchronization between neural populations in patients with Internet gaming disorder (IGD), patients with alcohol use disorder (AUD), and healthy controls (HCs) using resting-state electroencephalography (EEG) coherence analyses. For this study, 92 adult males were categorized into three groups: IGD (n = 30), AUD (n = 30), and HC (n = 32). The IGD group exhibited increased intrahemispheric gamma (30–40 Hz) coherence compared to the AUD and HC groups regardless of psychological features (e.g., depression, anxiety, and impulsivity) and right fronto-central gamma coherence positively predicted the scores of the Internet addiction test in all groups. In contrast, the AUD group showed marginal tendency of increased intrahemispheric theta (4–8 Hz) coherence relative to the HC group and this was dependent on the psychological features. The present findings indicate that patients with IGD and AUD exhibit different neurophysiological patterns of brain connectivity and that an increase in the fast phasic synchrony of gamma coherence might be a core neurophysiological feature of IGD.

“…59 Furthermore, an electroencephalogram study found higher impulsiveness in young adults who are Internet addicts. 60 It would not be surprising if Internet-addicted adolescents were found to have a different personality profile than others, with lower extraversion and higher neuroticism and psychoticism. 61 Behavioral and emotional problems are more common in adolescents who are addicted to Internet use than in their peers.…”

Internet addiction has become a serious behavioral health problem in Asia. However, there are no up-to-date country comparisons. The Asian Adolescent Risk Behavior Survey (AARBS) screens and compares the prevalence of Internet behaviors and addiction in adolescents in six Asian countries. A total of 5,366 adolescents aged 12-18 years were recruited from six Asian countries: China, Hong Kong, Japan, South Korea, Malaysia, and the Philippines. Participants completed a structured questionnaire on their Internet use in the 2012-2013 school year. Internet addiction was assessed using the Internet Addiction Test (IAT) and the Revised Chen Internet Addiction Scale (CIAS-R). The variations in Internet behaviors and addiction across countries were examined. The overall prevalence of smartphone ownership is 62%, ranging from 41% in China to 84% in South Korea. Moreover, participation in online gaming ranges from 11% in China to 39% in Japan. Hong Kong has the highest number of adolescents reporting daily or above Internet use (68%). Internet addiction is highest in the Philippines, according to both the IAT (5%) and the CIAS-R (21%). Internet addictive behavior is common among adolescents in Asian countries. Problematic Internet use is prevalent and characterized by risky cyberbehaviors.

“…Previous research has shown that patients with IGD demonstrated dysfunctional brain electrical activities during the resting-state. Specifically decreased beta power and increased gamma power during the resting-state were found in patients with IGD compared with healthy controls, and these brain changes were related to impulsivity (Choi et al, 2013). Thus, investigation of the brains of patients with IGD during the resting-state may increase our understanding of the intrinsic brain changes underlying the cognitive dysfunction observed in IGD.…”
