Characteristics of attention deficit of attention-deficit hyperactivity disorder(ADHD) were investigated by administering six computerized attention tests of Vienna Test System and four neuropsychological tests to children aged 6-12, with ADHD(n=21) and age-matched normal control children(n=22). The findings indicated that ADHD children show lower level of vigilance, more decline of performance in vigilance task on time, and impaired preparedness to response. They also have selective attention deficit on monitoring tasks, but did not have sustained attention deficit compared with normal control children. On the tasks wich overload their information processing capacity, ADHD children show more impulsive response pattern than normal control children. The performance of ADHD was worse than control on the neuropsychological tests sensitive to frontal lobe dysfunction. The presense 'These' attention deficits supports the theory that the defect of ADHD is due to the dysfunction of more than one brain region, including brain stem reticular formation and frontal lobe.

The purpose of this study was to examine the reliability and validity of attention deficit disorder evaluation scale-school version(ADDES-SV). Between October 1996 and November 1996, ADDES-SV was administered to 263 elementary school students in the second grade and between Jun 1996 and October 1996, 28 attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.88, that of impulsivity was 0.80, that of hyperactivity was 0.83 and total score was 0.83. In the reliability test by internal consistancy, the Cronbach $\alpha$ coefficient was significantly high and that of inattention was 0.98, that of impulsivity was 0.87, that of hyperactivity was 0.87(p<0.05). The half-sprit reliability coefficient by first-second half method showed high correlation and that of inattention was part 1: 0.96, part 2: 0.96 impulsivity was part 1: 0.95, part 2: 0.93, hyperactivity was part 1: 0.92, part 2: 0.94(p<0.05). Inter-rater reliability by pearson correlation coefficient was significantly high and that of inattention was 0.92, that of impulsivity was 0.87, that of hyperactivity was 0.89 and total score was 0.89. The concurrent validity between ADDES-SV and CAP scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.79 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in ADDES-SV was 94.6%. In this point of view, ADDES-SV scale showed high reliability and validity in applying to Korean subjects and was proved to be the useful screening test tool for attention deficit hyperactivity disorder research.

Objectives : The aim of this study was to investigate Korean Wechsler Intelligence profiles and specific abilities related to attention problem of children with attention-deficit hyperactivity disorder (ADHD). Methods : The Korean Wechsler Intelligence Scale for Children-fourth edition (K-WISC-IV) and Advanced Test of Attention (ATA) were administered to 91 children and adolescents (age $8.5{\pm}2.6$ years, 73 boys) with ADHD. Pearson correlation and independent t-tests were used. Results : The means of Working Memory Index (WMI) and Processing Speed Index (PSI) showed a score of low average in K-WISC-IV. WMI scores for the K-WISC-IV showed clinically significant correlations with omission errors, commission errors, and response time variability on auditory ATA. PSI scores also showed significant correlations with response time and variability on visual ATA. In addition, significantly lower digit span backward scores were observed in hyperactive-impulsive/combined subtypes compared to inattentive subtype (t=3.60, p<.001). Conclusion : Children with ADHD showed significantly lower scores in WMI and PSI which were clinically correlated with ATA scores, and hyperactive-impulsive/combined subtypes showed poorer working memory functions in WMI. Follow-up studies are proposed.

Objectives: This study aimed to evaluate the efficacy of the attention-deficit/hyperactivity disorder (ADHD)-After School Checklist (ASK) by comparing the results of the Comprehensive Attention Test (CAT) and Clinical Global Impression-Severity (CGI-S) Scale and then by calculating the area under the receiver operating characteristic (ROC) curve. Methods: We performed correlation analyses on the ASK and CAT results and then the ASK and CGI-S results. We created a ROC curve and evaluated performance on the ASK as a diagnostic tool. We then analyzed the test results of 1348 subjects (male 56.8%), including 1201 subjects in the general population and 147 ADHD subjects, aged 6-15 years, from kindergarten to middle school in Seoul and Gyeonggi province, South Korea. Results: According to the correlation analyses, ASK scores and the Attention Quotient (AQ) of CAT scores showed a significant correlation of -0.20--0.29 (p<0.05). The t-test between ADHD scores and CGI-S also showed a significant correlation (t=-2.55, p<0.05). The area under the ROC curve was calculated as 0.81, indicating good efficacy of the ASK, and the cut-off score was calculated as 15.5. Conclusion: The ASK can be used as a valid tool not only to evaluate functional impairment of ADHD children and adolescents but also to screen ADHD.

Objective : This study was designed to find the latest intervention trends in treatment of children with attention deficit hyperactivity disorder (ADHD) in South Korea. Methods : Studies on ADHD published in Korean journals from January 2004 to December 2018 were reviewed. The databases used were DBpia, Google Scholar, RISS, and KISS. The search terms were "attention deficit hyperactivity," "child," and "intervention." A total of 14 studies were selected. The results of this study were as follows: Patient, Intervention, Comparison, Outcome. Results : The level of evidence was the highest in the single subject study of level IV, and the methodological quality was the most common study. The interventional metronome (IM) intervention was the most frequently used, and the evaluation tools used in the measurement were the Long Form Assessment of the Interactive Metronome and the Korean Behavior Child Checklist. The Korean ADHD interventions showed statistically significant improvement in concentration, hyperactivity, task performance, excessive language use, and timing. Conclusions : Various types of interventions were provided for children with ADHD in South Korea. The interventions showed positive effects, and provided basic data for evidence-based implementation in clinical practice. In the future, a model study should be conducted, to establish an effective service delivery system, as well as ongoing research on children with ADHD.

Objectives : Attention-deficit hyperactivity disorder(ADHD) is characterized by significant impairments in executive functions, with a prevalence of approximately 3-5% of all children worldwide. The goal of this study was to examine the relationship between executive functions and electrophysiological activities in children and adolescents with ADHD. Methods : In 31 patients with ADHD, resting-state EEG was recorded, and Comprehensive Attention Test(CAT), Stroop Color-Word Inference Test(Stroop CWIT), Trail Making Test(TMT), and Wisconsin Card Sorting Test(CST) were administered. Korean version of the ADHD Rating Scale(K-ARS) was assessed. Results : Alpha and beta power positively correlated with the Attention Quotient(AQ), while delta power negatively correlated with AQ from CAT. In the Stroop CWIT, decreased delta power and increased beta power were related to higher performance. Power of the alpha band increased with higher TMT performance. Moreover, delta power negatively correlated with good performance on the CST, while alpha and high gamma band showed a positive correlation. Correlation with the parent-rating of ADHD symptoms showed a negative correlation between alpha power and higher scores on the K-ARS. Conclusions : These findings indicate that relative power in higher frequency bands of EEG is related to the higher executive function in children and adolescents with ADHD, while the association with the relative power in lower frequency bands of EEG seem to be vice versa. Furthermore, the findings suggest that QEEG may be a useful adjunctive tool in assessing patients with ADHD.

Recently attention deficit of children has caused various social problems. Those children who has symptoms like ADHD (Attention Deficit/Hyperactivity Disorder) has to be provided with methods which can enhance their attention level in a child-friendly way such as 3D games. This paper shows a research on how to measure the level of attention for attention deficit children using their favorite 3D games. Firstly, we speculated on the methods about attention measurement used in the medical area. And then we searched measurement variables which can effectively evaluate the level of attention during a game play time. Secondly, we have conducted experiment whether there exists difference about the value of the measurement variables between the two groups, normal children group and attention deficit children group. Those variables are omission error, commission error, average response time, and standard deviation of response time. Though our experiment has only been limited to visual attention level, four measurement variables revealed mutual differences.

Attention-deficit/hyperactivity disorder(ADHD) is one of the most common childhood-onset psychlatric disorders. It is distinguished by symptoms of inattention, hyperactivity, and impulsivity. ADHD may be accompanied by learning disabilities, depression, anxiety, conduct disorder, and oppositional defiant disorder. The etiology of ADHD is unknown, and the disorder may have several different causes. Individual with ADHD present in childhood and may continue to show symptoms as they enter adolescence and adult life. Public interest in ADHD has increased along with debate in the media concerning the diagnostic process and treatment strategies. The purpose of this study is oriental medical approach to ADHD. This study was progressed for oriental diagnosis and treatment for ADHD. In oriental medicine, the reason of ADHD was deficiency of the kidney, hyperactivity of the liver(腎虛肝亢), deficiency of the heart and the spleen(心脾不足), heart disturbed by phlegm and heat(痰熱擾心). The method of medical treatment was nourishing the kidney and checking exuberance of yang(滋腎潛陽), relieving mental stress and promoting wisdom(寧神益智), nourishing the heart and strengthening the spleen(養心健脾), tranquilzation(安神定志). removing heat-phlegm(淸熱化痰), inducing resuscitation and tranquilzation(開窮安神). The prescription was commonly used as Liuwei Dihuang Wan jiajian(六味地黃丸加減), Guipi Tang he Ganmai Dazao Tang jiajian(歸脾湯合甘麥大棗湯加減), Huanglian Wendan Tang jiawei(溫黃連溫膽湯加味). It should help primary care providers in their assessment of a common child health problem.

Authors report a case of separation anxiety disorder, which developed as a side effect during haloperidol treatment of Tourette syndrome(TS). In this case, 14 years old boy developed attention deficit symptoms during his infancy. At 4th grade of primary school, he developed vocal tic, motor tic, and coprolalia. With 5mg/day of haloperidol treatment his symptoms of TS were subsided. During the treatment, he developed features of separation anxiety disorder, including dependence, pleading, clinging, and sadness. Symptoms of attention deficit and separation anxiety disorder were improved by 25mg/day of imipramine treatment. During haloperidol treatment of TS, careful observation may be needed whether separation anxiety disorder-like symptom develops.

Objectives Internet gaming disorder (IGD) is associated with attention deficit/hyperactivity disorder (ADHD) or depression etc. We tried to examine the mediating effects of depression in the relationship between ADHD and IGD. Methods This study was conducted on 2000 people who participated in on-line survey among 14-39 year-old men and women in 2017. And we clarified the relationship among IGD, ADHD, and depression and tested the mediation model. The mean and standard deviation of the main variables were calculated and correlation analysis was performed to confirm the relationship among the main variables. In order to test the mediating effect of depression on the relationship between ADHD and IGD, the structural equation model was implemented using AMOS 21 (IBM). Results There were significant correlations among the variables; IGD, ADHD and depression. Depression had a mediating effect 0.23 (95% confidence interval : 0.17-0.28) in the relationship between IGD and ADHD. Conclusions This study showed that depression can mediate ADHD and IGD. Therefore, the evaluation and management of depression and ADHD should be included in the diagnosis and treatment of IGD.
