김동일(Dongill Kim),이덕종(Deokjong Lee),김진경(Jin Kyoung Kim),성고은(Goeun Seong),정영철(Young-Chul Jung) 한국중독정신의학회 2017 중독정신의학 Vol.21 No.2
Objectives : Young adults with internet addiction and smartphone addiction have a high prevalence of psychiatric comorbidity ; however, the possible differences between digital devices-desktop PC vs. smartphone-are still under debate. Methods : Participants were 148 young male adults (mean age=23.8±2.3 years). They were divided into the following four groups: General user group, Internet addiction group, Smartphone addiction group, and Dual addiction group. In order to assess the difference between devices, internet addiction severity was evaluated only based on the activity using desktop personal computers. The comorbid psychopathology-depression, anxiety, alcohol use-related symptoms, adult ADHD symtpoms (i.e., inattention, hyperactivity, impulsivity), childhood ADHD symptoms -was assessed by using self-report scales. Results : On comparing the prevalence of comorbid psychopathology among the four groups, 66.9% of patients in the Internet addiction group, 41.7% of patients in the Smartphone addiction group, and 59.6% of patients in the Dual addiction group had at least one comorbid psychopathology. Compared to the smartphone addiction group, the internet addiction group showed higher levels of comorbid depression and adult ADHD psychopathology. Internet addiction severity correlated with childhood ADHD, depression and anxiety. In contrast, smartphone addiction severity correlated with childhood ADHD and anxiety. Conclusion : Our results showed that internet addiction and smartphone addiction have different comorbid psychopathologies

인터넷 게임장애 및 알코올 사용장애 환자의 하두정소엽 회백질 부피 변화
최항녕(Hangnyoung Choi),정영철(Young-Chul Jung),이덕종(Deokjong Lee) 한국중독정신의학회 2020 중독정신의학 Vol.24 No.2
Objectives : The purpose of the present study was to conduct a comparison of structural brain alterations between people with Internet gaming disorder (IGD) and alcohol use disorder (AUD) in young males. Methods : Twenty-four young males with IGD, 22 young males with AUD, and 30 healthy control (HC) subjects participated in this study. We applied voxel-based morphometric analysis with diffeomorphic anatomical registration using an exponentiated Lie algebra algorithm. A whole-brain analysis was conducted to investigate the locations of gray matter volume differences between the groups. Results : Both the Individuals with IGD and AUD had significantly smaller gray matter volume in the left inferior parietal lobe than the healthy controls (IGD<HC, p=0.005; AUD<HC, p<0.001). There was no significant difference in gray matter volume in the inferior parietal lobule between the IGD and AUD groups. Conclusion : We demonstrated that IGD and AUD shared structural abnormalities in the inferior parietal lobule. The inferior parietal lobule is involved in the integration between top-down and bottom-up control. The volume of the gray matter in the inferior parietal lobule is known to be highly influenced by genetic factors. The results of this study suggest susceptibility shared between people with IGD and those with AUD.
