Comparison of QEEG Findings between Adolescents with Attention Deficit Hyperactivity Disorder (ADHD) without Comorbidity and ADHD Comorbid with Internet Gaming Disorder.

Internet gaming disorder (IGD) is often comorbid with attention deficit hyperactivity disorder (ADHD). In this study, we compared the neurobiological differences between ADHD comorbid with IGD (ADHD+IGD group) and ADHD without comorbidity (ADHD-only group) by analyzing quantitative electroencephalogram (QEEG) findings. We recruited 16 male ADHD+IGD, 15 male ADHD-only adolescent patients, and 15 male healthy controls (HC group). Participants were assessed using Young's Internet Addiction Scale and ADHD Rating Scale. Relative power and inter- and intra-hemispheric coherences of brain waves were measured using a digital electroencephalography (EEG) system. Compared to the ADHD-only group, the ADHD+IGD group showed lower relative delta power and greater relative beta power in temporal regions. The relative theta power in frontal regions were higher in ADHD-only group compared to HC group. Inter-hemispheric coherence values for the theta band between F3–F4 and C3–C4 electrodes were higher in ADHD-only group compared to HC group. Intra-hemispheric coherence values for the delta, theta, alpha, and beta bands between P4–O2 electrodes and intra-hemispheric coherence values for the theta band between Fz–Cz and T4–T6 electrodes were higher in ADHD+IGD group compared to ADHD-only group. Adolescents who show greater vulnerability to ADHD seem to continuously play Internet games to unconsciously enhance attentional ability. In turn, relative beta power in attention deficit in ADHD+IGD group may become similar to that in HC group. Repetitive activation of brain reward and working memory systems during continuous gaming may result in an increase in neuronal connectivity within the parieto-occipital and temporal regions for the ADHD+IGD group.

Factors associated with Internet addiction: Cross-sectional study of Turkish adolescents.

The aim of this study was to investigate the prevalence of Internet addiction (IA), and the relationship between sociodemographic characteristics, depression, anxiety, attention-deficit-hyperactivity disorder (ADHD) symptoms and IA in adolescents. This was a cross-sectional school-based study with a representative sample of 468 students aged 12-17 years at the first trimester of the 2013-2014 academic year. The students were assessed using Young's Internet Addiction Scale, Children's Depression Inventory, Beck Anxiety Inventory, Conners' Parent Rating Scale, Conners' Teacher Rating Scale, Hollingshead-Redlich Scale, and the information form including characteristics of Internet use and socioeconomic status (SES). The relationship between these factors and Internet use was examined. Approximately 1.6% of students were identified as having IA, whereas 16.2% had possible IA. There were significant correlations between IA and depression, anxiety, attention disorder and hyperactivity symptoms in adolescents. Smoking was also related to IA. There was no significant relationship between IA and age, sex, body mass index, school type, and SES. Depression, anxiety, ADHD and smoking addiction are associated with PIU in adolescent students. Preventive public health policies targeting the psychological wellbeing of young people are needed.

Treatment of Internet Addiction with Anxiety Disorders: Treatment Protocol and Preliminary Before-After Results Involving Pharmacotherapy and Modified Cognitive Behavioral Therapy.

BackgroundThe growth of the Internet has led to significant change and has become an integral part of modern life. It has made life easier and provided innumerous benefits; however, excessive use has brought about the potential for addiction, leading to severe impairments in social, academic, financial, psychological, and work domains. Individuals addicted to the Internet usually have comorbid psychiatric disorders. Panic disorder (PD) and generalized anxiety disorder (GAD) are prevalent mental disorders, involving a great deal of damage in the patient’s life.ObjectiveThis open trial study describes a treatment protocol among 39 patients with anxiety disorders and Internet addiction (IA) involving pharmacotherapy and modified cognitive behavioral therapy (CBT).MethodsOf the 39 patients, 25 were diagnosed with PD and 14 with GAD, in addition to Internet addiction. At screening, patients responded to the MINI 5.0, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Clinical Global Impressions Scale, and the Young Internet Addiction Scale. At that time, IA was observed taking into consideration the IAT scale (cutoff score above 50), while anxiety disorders were diagnosed by a psychiatrist. Patients were forwarded for pharmacotherapy and a modified CBT protocol. Psychotherapy was conducted individually, once a week, over a period of 10 weeks, and results suggest that the treatment was effective for anxiety and Internet addiction.ResultsBefore treatment, anxiety levels suggested severe anxiety, with an average score of 34.26 (SD 6.13); however, after treatment the mean score was 15.03 (SD 3.88) (P<.001). A significant improvement in mean Internet addiction scores was observed, from 67.67 (SD 7.69) before treatment, showing problematic internet use, to 37.56 (SD 9.32) after treatment (P<.001), indicating medium Internet use. With respect to the relationship between IA and anxiety, the correlation between scores was .724.ConclusionsThis study is the first research into IA treatment of a Brazilian population. The improvement was remarkable due to the complete engagement of patients in therapy, which contributed to the success of the treatment from a behavioral perspective, and gave patients the confidence to continue to manage Internet use in their lives.

The effects of a virtual reality treatment program for online gaming addiction

Background and objectiveNeuroimaging studies have demonstrated dysfunction in the brain reward circuit in individuals with online gaming addiction (OGA). We hypothesized that virtual reality therapy (VRT) for OGA would improve the functional connectivity (FC) of the cortico-striatal-limbic circuit by stimulating the limbic system. MethodsTwenty-four adults with OGA were randomly assigned to a cognitive behavior therapy (CBT) group or VRT group. Before and after the four-week treatment period, the severity of OGA was evaluated with Young's Internet Addiction Scale (YIAS). Using functional magnetic resonance imaging, the amplitude of low-frequency fluctuation (ALFF) and FC from the posterior cingulate cortex (PCC) seed to other brain areas were evaluated. Twelve casual game users were also recruited and underwent only baseline assessment. ResultsAfter treatment, both CBT and VRT groups showed reductions in YIAS scores. At baseline, the OGA group showed a smaller ALFF within the right middle frontal gyrus and reduced FC in the cortico-striatal-limbic circuit. In the VRT group, connectivity from the PCC seed to the left middle frontal and bilateral temporal lobe increased after VRT. ConclusionVRT seemed to reduce the severity of OGA, showing effects similar to CBT, and enhanced the balance of the cortico-striatal-limbic circuit.

성인 인터넷 중독과 일주기 리듬의 연관성

Background and Objectives: Internet addiction is an increasing problem in Korea. The previous studies in this area have targeted adolescents and young adults. This study was conducted to examine the risk of internet addiction in Korean adults and the effect of internet addiction on circadian rhythm. Materials and Methods: For this study, 508 subjects were chosen through population proportional sampling to represent the adult population in Korea, 325 of whom were included based on the Alcohol Use Disorder Identification Test-Korea (Audit-K), Zung's Self-Rating Depression Scale (SDS), drug use in the past year, and suicide attempts. In these subjects, sociodemographic factors including age, gender, and residential area were analyzed, and Young's Internet Addiction Scale (IAS), Morningness-Eveningness Questionnaire (MEQ), and an online survey examining sleep onset time on weekdays and weekends, wake-up time, and caffeinated drink intake were executed. Results: Of the 325 subjects, 136 (41.8%) belonged to a high-risk internet addiction group (), and 189 (58.2%) belonged to a normal group (IAS ) in the high-risk group (p = 0.024), who also showed a high proportion of caffeinated drink intake (p

Brain connectivity and psychiatric comorbidity in adolescents with Internet gaming disorder.

Prolonged Internet video game play may have multiple and complex effects on human cognition and brain development in both negative and positive ways. There is not currently a consensus on the principle effects of video game play neither on brain development nor on the relationship to psychiatric comorbidity. In this study, 78 adolescents with Internet gaming disorder (IGD) and 73 comparison subjects without IGD, including subgroups with no other psychiatric comorbid disease, with major depressive disorder and with attention deficit hyperactivity disorder (ADHD), were included in a 3 T resting state functional magnetic resonance imaging analysis. The severity of Internet gaming disorder, depression, anxiety and ADHD symptoms were assessed with the Young Internet Addiction Scale, the Beck Depression Inventory, the Beck Anxiety Inventory and the Korean ADHD rating scales, respectively. Patients with IGD showed an increased functional correlation between seven pairs of regions, all satisfying q < 0.05 False discovery rates in light of multiple statistical tests: left frontal eye field to dorsal anterior cingulate, left frontal eye field to right anterior insula, left dorsolateral prefrontal cortex (DLPFC) to left temporoparietal junction (TPJ), right DLPFC to right TPJ, right auditory cortex to right motor cortex, right auditory cortex to supplementary motor area and right auditory cortex to dorsal anterior cingulate. These findings may represent a training effect of extended game play and suggest a risk or predisposition in game players for over-connectivity of the default mode and executive control networks that may relate to psychiatric comorbidity.

SY20-4 * VIRTUAL REALITY THERAPY FOR INTERNET GAMING DISORDER

Introduction. Studies using functional magnetic resonance imaging (fMRI) have demonstrated dysfunction in the cortico-limbic circuit in individuals with Internet gaming disorder (IGD). We hypothesized that virtual reality therapy (VRT) for IGD would improve the functional connectivity of the cortico-limbic circuit. Methods. In the Chung-Ang University Hospital, 24 adults with IGD and 12 casual game users were recruited. IGD group was randomly assigned into the cognitive behavior therapy (CBT) group (N = 12) and VRT group (N = 12). The severity of IGD was evaluated with the Young's Internet Addiction Scale (YIAS) before and after the treatment period. Using resting-state fMRI, functional connectivity from posterior cingulate (PCC) seed to other brain areas was investigated. Results. During the treatment period, both CBT and VRT groups showed significant reductions on the YIAS scores. At baseline, IGD group showed a reduced connectivity in cortico-striatal-limbic circuit. In the CBT group, the connectivity from PCC seed to bilateral lenticular nucleus and cerebellum increased during 8-session CBT. In the VRT group, the connectivity from PCC seed to left thalamus-frontal lobe-cerebellum increased during 8-session VRT. Conclusion. Treatment of IGD using VRT seemed to improve the severity of IGD, which showed similar effectiveness to CBT, and enhance the balance of the cortico-striatal-limbic circuit.

Proton magnetic resonance spectroscopy (MRS) in on-line game addiction

Recent brain imaging studies suggested that both the frontal and temporal cortices are important candidate areas for mediating the symptoms of internet addiction. We hypothesized that deficits of prefrontal and temporal cortical function in patients with on-line game addiction (PGA) would be reflected in decreased levels of N-acetyl aspartate (NAA) and cytosolic, choline containing compound (Cho). Seventy three young PGA and 38 age and sex matched healthy control subjects were recruited in the study. Structural MR and 1H MRS data were acquired using a 3.0 T MRI scanner. Voxels were sequentially placed in right frontal cortex and right medial temporal cortices. In the right frontal cortex, the levels of NAA in PGA were lower than those in healthy controls. In the medial temporal cortex, the levels of Cho in PGA participants were lower than those observed in healthy controls. The Young Internet Addiction Scale (YIAS) scores and perseverative responses in PGA were negatively correlated with the level of NAA in right frontal cortex. The Beck Depressive Inventory (BDI) scores in the PGA cohort were negatively correlated with Cho levels in the right temporal lobe. To the best of our knowledge, this is the first MRS study of individuals with on-line game addiction. Although, the subjects with on-line game addiction in the current study were free from psychiatric co-morbidity, patients with on-line game addiction appear to share characteristics with ADHD and MDD in terms of neurochemical changes in frontal and temporal cortices.

Association Between Internet Use and Sleep Problems in Adolescents.

Sleep problems are commonly encountered in adolescents. It has been shown that electronic media have a negative influence on the sleep quality and daytime functioning in adolescents. This study aims to investigate the association between internet use and sleep problems in adolescents. A total of 1212 adolescents were recruited to the study. Self-report study questionnaire included two main parts: Young's Internet Addiction Scale (IAS) and a semi-structured inquiry on sleep habits/problems. Of the study sample, 16% (n=198) reported their sleep quality as bad or very bad. One-fourth of the sample reported using internet everyday and 27% of them reported spending more than one hour when online. The mean IAS total score was 35.56±13.87. Adolescents with a higher IAS score reported getting to bed later in the night, needing more time to fall asleep and having an increased number of awakenings in the night than the adolescents with lower IAS score (p=.001). They were also found to have higher frequencies of several sleep problems including difficulty in initiating and sustaining sleep, difficulty in waking up and feelings of sleepiness in day. In addition, sleep quality of them was worse when compared to the adolescents with a lower IAS score (p=.001). Problematic sleep habits and sleep problems were found to be more frequent in adolescents with a higher IAS total score. Health care providers must be aware of the possible negative impact of excessive and uncontrolled internet use on adolescents' sleep habits.

Poster #S60 WHITE MATTER ALTERATIONS AND STRUCTURAL CONNECTIVITY IN FIRST-EPISODE ANTIPSYCHOTIC-NAIVE SCHIZOPHRENIA PATIENTS

Online game addiction (OGA) has attracted greater attention as a serious public mental health issue. However, there are only a few brain magnetic resonance imaging studies on brain structure about OGA. In the current study, we used voxel-based morphometry (VBM) analysis and tract-based spatial statistics (TBSS) to investigate the microstructural changes in OGA and assessed the relationship between these morphology changes and the Young's Internet Addiction Scale (YIAS) scores within the OGA group. Compared with healthy subjects, OGA individuals showed significant gray matter atrophy in the right orbitofrontal cortex, bilateral insula, and right supplementary motor area. According to TBSS analysis, OGA subjects had significantly reduced FA in the right genu of corpus callosum, bilateral frontal lobe white matter, and right external capsule. Gray matter volumes (GMV) of the right orbitofrontal cortex, bilateral insula and FA values of the right external capsule were significantly positively correlated with the YIAS scores in the OGA subjects. Our findings suggested that microstructure abnormalities of gray and white matter were present in OGA subjects. This finding may provide more insights into the understanding of the underlying neural mechanisms of OGA.

Prevalence and patterns of psychiatric disorders in referred adolescents with Internet addiction

To investigate prevalence and patterns of psychiatric disorders in young subjects with Internet addiction (IA). Subjects were taken from a sample of patients, aged 10-18 years old, referred to Istanbul Medical Faculty, Child and Adolescent Psychiatry Department due to a variety of behavioral and emotional problems alongside problematic Internet use. Inclusion criteria included IQ ≥70 and score ≥80 on Young's Internet Addiction Scale (YIAS). Psychiatric comorbidity was assessed using the Turkish version of the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version. Subjects were 45 boys (75%) and 15 girls (25%) with an age range of 10-18 years old (mean age, 13.38 ± 1.79 years). A total of 60% (n = 36) had been using Internet for ≥5 years. Mean hours/week spent on the Internet was 53.7 (range, 30-105 h) and the average YIAS score was 85. All subjects (100%) had at least one and 88.3% (n = 53) had at least two comorbid psychiatric disorders. The frequency of diagnostic groups were as follows: behavioral disorder, n = 52 (86.7%); anxiety disorder, n = 43 (71.7%); mood disorder, n = 23 (38.3%); elimination disorder, n = 16 (26.7%); tic disorder, n = 10 (16.7%); and substance use disorder, n = 4 (6.7%). The most common psychiatric disorders were attention-deficit hyperactivity disorder (n = 53; 83.3%), social phobia (n = 21; 35.0%) and major depressive disorder (n = 18; 30.0%). High rates of psychiatric comorbidity, particularly behavioral, anxiety and mood disorders were found in young subjects with IA. Because the presence of psychiatric disorders may affect the management /prognosis of IA, assessment should include that for other psychiatric disorders.

Gray matter and white matter abnormalities in online game addiction

Online game addiction (OGA) has attracted greater attention as a serious public mental health issue. However, there are only a few brain magnetic resonance imaging studies on brain structure about OGA. In the current study, we used voxel-based morphometry (VBM) analysis and tract-based spatial statistics (TBSS) to investigate the microstructural changes in OGA and assessed the relationship between these morphology changes and the Young's Internet Addiction Scale (YIAS) scores within the OGA group. Compared with healthy subjects, OGA individuals showed significant gray matter atrophy in the right orbitofrontal cortex, bilateral insula, and right supplementary motor area. According to TBSS analysis, OGA subjects had significantly reduced FA in the right genu of corpus callosum, bilateral frontal lobe white matter, and right external capsule. Gray matter volumes (GMV) of the right orbitofrontal cortex, bilateral insula and FA values of the right external capsule were significantly positively correlated with the YIAS scores in the OGA subjects. Our findings suggested that microstructure abnormalities of gray and white matter were present in OGA subjects. This finding may provide more insights into the understanding of the underlying neural mechanisms of OGA.

Combined cognitive behavioral therapy and bupropion for the treatment of problematic on-line game play in adolescents with major depressive disorder

The purpose of the current study was to evaluate the efficacy of cognitive behavioral therapy (CBT) in combination with bupropion for treatment of problematic on-line game play in adolescents with co-morbid major depressive disorder. Sixty-five depressed adolescents with excessive on-line game play were randomly assigned to a CBT group (CBT-Med group (N=32)) or a clinical control group (Med group (N=33)). Measures of severity of internet use, depressive symptoms, anxiety symptoms, life satisfaction and school adaptation were assessed at baseline, after the 8week intervention, and at the end of a 4week follow-up post-treatment period. Young Internet Addiction Scale scores in the CBT-Med group were reduced compared to those of the Med group, but there was no significant difference in the change of depression scores between two groups. The mean anxiety scores in the CBT-Med group did not change while those in the Med group were increased. The mean life satisfaction scores in the CBT-Med group were increased compared to those of the Med group. CBT in combination with bupropion may be effective for the treatment of depressed adolescents with on-line game addiction, particularly in reducing on-line game play and anxiety, as well as in improving life satisfaction.

Abnormal White Matter Integrity in Adolescents with Internet Addiction Disorder: A Tract-Based Spatial Statistics Study

BackgroundInternet addiction disorder (IAD) is currently becoming a serious mental health issue around the globe. Previous studies regarding IAD were mainly focused on associated psychological examinations. However, there are few studies on brain structure and function about IAD. In this study, we used diffusion tensor imaging (DTI) to investigate white matter integrity in adolescents with IAD.Methodology/Principal FindingsSeventeen IAD subjects and sixteen healthy controls without IAD participated in this study. Whole brain voxel-wise analysis of fractional anisotropy (FA) was performed by tract-based spatial statistics (TBSS) to localize abnormal white matter regions between groups. TBSS demonstrated that IAD had significantly lower FA than controls throughout the brain, including the orbito-frontal white matter, corpus callosum, cingulum, inferior fronto-occipital fasciculus, and corona radiation, internal and external capsules, while exhibiting no areas of higher FA. Volume-of-interest (VOI) analysis was used to detect changes of diffusivity indices in the regions showing FA abnormalities. In most VOIs, FA reductions were caused by an increase in radial diffusivity while no changes in axial diffusivity. Correlation analysis was performed to assess the relationship between FA and behavioral measures within the IAD group. Significantly negative correlations were found between FA values in the left genu of the corpus callosum and the Screen for Child Anxiety Related Emotional Disorders, and between FA values in the left external capsule and the Young's Internet addiction scale.ConclusionsOur findings suggest that IAD demonstrated widespread reductions of FA in major white matter pathways and such abnormal white matter structure may be linked to some behavioral impairments. In addition, white matter integrity may serve as a potential new treatment target and FA may be as a qualified biomarker to understand the underlying neural mechanisms of injury or to assess the effectiveness of specific early interventions in IAD.

Relationship of childhood physical abuse and internet addiction disorder in adolescence: the mediating role of self-esteem

To find out whether the effects of childhood physical abuse on internet addiction disorder in adolescence could be mediated by self-esteem. 3798 high school students selected from 76 classes in Grade One and Grade Two, were asked to fill in the anonymous questionnaire, which including the demographic characteristics of students, Young's Internet Addiction Scale, Parent-Child Conflict Tactics Scales and Rosenberg's Self-Esteem Scale. Childhood physical abuse could directly predict less self-esteem and internet addiction disorder (r = -0.108, P < 0.01, r = 0.057, P < 0.01) and had significant indirect effects on internet addiction disorder which could be mediated through self-esteem (a = -0.703, standardized b = -0.104, z = 5.052, P < 0.001). Self-esteem had mediated 22.5% of the childhood physical abuse cases on their internet addiction disorders during the period of adolescence. Self-esteem could partially mediate the relationship between childhood physical abuse and internet addiction disorder. The mediating roles of self-esteem suggested that salient leverage points could make a change through empowerment training, self-esteem group training on self-esteem enhancement in the stage of adolescence.

P-303 - Internet addiction disorder among adolescent students

Background The Internet addiction disorder(IAD) is conceptualized by an individuals inability to control his or her use of the internet which causes marked distress &/functional impairment. Aim It was a cross-sectional study with aimed to find out the proportion of IAD among adolescent students & association of age,sex, educational level with addiction as well as relation of Internet addiction(IA) to different internet related activities & to determine severity of addiction. Methods The study was conducted purposively from 5 schools & 7 colleges of Dhaka City of Bangladesh from January to June 2011.In total of 797 students(438 were male, 359 were female, mean age:16.47 ± 1.21 years) of grade IX,X & XII were recruited. A self-administered questionnaire & Young's Internet addiction scale were applied. Results Among 797 students,161(20.20%) were found as IAD. Out of 797 respondents,40.15% were school (Grade IX & X) & 59.85% were college students(Grade XII).IA were identified more among elderly adolescent(16–18 years) students(22.6%) & male students were more addicted(24.4%) than female students(15%).There was no relation found between educational level & IA. Association between information seeking behavior(p Conclusion This study demonstrated that IA presents among Bangladeshi urban adolescent students. It will create awareness among teachers, parents, policy maker & students about this addiction.

Bupropion sustained release treatment decreases craving for video games and cue-induced brain activity in patients with internet video game addiction.

Bupropion has been used in the treatment of patients with substance dependence based on its weak inhibition of dopamine and norepinephrine reuptake. We hypothesized that 6 weeks of bupropion sustained release (SR) treatment would decrease craving for Internet game play as well as video game cue-induced brain activity in patients with Internet video game addiction (IAG). Eleven subjects who met criteria for IAG, playing StarCraft (>30 hr/week), and eight healthy comparison subjects (HC) who had experience playing StarCraft (<3 days/week and <1 hr/day). At baseline and at the end of 6 weeks of bupropion SR treatment, brain activity in response to StarCraft cue presentation was assessed using 1.5 Tesla functional MRI. In addition, symptoms of depression, craving for playing the game, and the severity of Internet addiction were evaluated by Beck Depression Inventory, self-report of craving on a 7-point visual analogue scale, and Young's Internet Addiction Scale, respectively. In response to game cues, IAG showed higher brain activation in left occipital lobe cuneus, left dorsolateral prefrontal cortex, and left parahippocampal gyrus than HC. After a 6 week period of bupropion SR, craving for Internet video game play, total game play time, and cue-induced brain activity in dorsolateral prefrontal cortex were decreased in the IAG. We suggest that bupropion SR may change craving and brain activity in ways that are similar to those observed in individuals with substance abuse or dependence.

Bupropion in the treatment of problematic online game play in patients with major depressive disorder

As one of the problematic behaviors in patients with major depressive disorder (MDD), excessive online game play (EOP) has been reported in a number of recent studies. Bupropion has been evaluated as a potential treatment for MDD and substance dependence. We hypothesized that bupropion treatment would reduce the severity of EOP as well as depressive symptoms. Fifty male subjects with comorbid EOP and MDD were randomly assigned to bupropion + education for internet use (EDU) or placebo + EDU groups. The current study consisted in a 12-week, prospective, randomized, double-blind clinical trial, including an eight-week active treatment phase and a four-week post treatment follow-up period. During the active treatment period, Young Internet Addiction Scale (YIAS) scores and the mean time of online game playing in the bupropion group were greatly reduced compared with those of the placebo group. The Beck Depression Inventory (BDI) scores in the bupropion group were also greatly reduced compared with those of the placebo group. During the four-week post-treatment follow-up period, bupropion-associated reductions in online game play persisted, while depressive symptoms recurred. Conclusively, bupropion may improve depressive mood as well as reduce the severity of EOP in patients with comorbid MDD and online game addiction.

P.7.c.004 Changes in parental depressive mood and quality of life following treatment of ADHD children

A number of studies about attention-deficit/hyperactivity disorder (ADHD) and Internet video game play have examined the prefrontal cortex and dopaminergic system. Stimulants such as methylphenidate (MPH), given to treat ADHD, and video game play have been found to increase synaptic dopamine. We hypothesized that MPH treatment would reduce Internet use in subjects with co-occurring ADHD and Internet video game addictions.Sixty-two children (52 males and 10 females), drug-naive, diagnosed with ADHD, and Internet video game players, participated in this study. At the beginning of the study and after 8 weeks of treatment with Concerta (OROS methylphenidate HCl, Seoul, Korea), participants were assessed with Young's Internet Addiction Scale, Korean version (YIAS-K), Korean DuPaul's ADHD Rating Scale, and the Visual Continuous Performance Test. Their Internet usage time was also recorded.After 8 weeks of treatment, the YIAS-K scores and Internet usage times were significantly reduced. The changes in the YIAS-K scores between the baseline and 8-week assessments were positively correlated with the changes in total and inattention scores from the Korean DuPaul's ADHD Rating Scale, as well as omission errors from the Visual Continuous Performance Test. There was also a significant difference in the number of omission errors among non–Internet-addicted, mildly Internet addicted, and severely Internet addicted participants.We suggest that Internet video game playing might be a means of self-medication for children with ADHD. In addition, we cautiously suggest that MPH might be evaluated as a potential treatment of Internet addiction.
