Attention Deficit Hyperactivity Disorder (ADHD) is one of the most general childhood problems occurs locally and internationally, but the causes of ADHD are not cleared yet. Therefore, this study tried to examine some parts of the causes of ADHD closely, and finally contribute to the medical treatment of ADHD and its precautionary measures, by measuring and comparing concentration of minerals in hairs of the patients of ADHD and their control group's children. which can analyze the relevance to ADHD and the mineral content in human bodies, and mutual relations between toxic minerals and essential minerals in human bodies. After collection of hairs from 200 children(5 to 7-year-old, boys: 159 girls:41) diagnosed as ADHD by medical specialists based on the standard of DSM-IV diagnosis and their control group's 177 children(boys: 138 girls:39), the mineral concentration of samples was measured through ICP-MS and compared. And correlations between toxic minerals and essential minerals in human bodies among patients group was analyzed. All the toxic minerals(Pb, Hg, Al, Cd, As) of hairs analyzed in the study showed more higher range of concentration in patients group in comparison with their control group. Among them, the concentration of Pb(3.27 $\pm$ 3.82 ppm) and As(0.16 $\pm$ 0.15 ppm) in patients group were significantly high compared to their control group. And in this study Pb among toxic minerals showed negative correlation with Zn(r = -0.43), Mg(r = -0.15) among essential minerals. Cd among toxic minerals showed negative correlation with Zn(r = -0.20) among essential minerals. As among toxic minerals showed negative correlation with Ca(r = -0.14) among essential minerals.

This study was performed in order to investigate the relationship between attention deficit hyperactivity disorder (ADHD), dietary habit and caffeine intake in upper-grade elementary school children. The total number of the study subjects was 237 students (111 boys and 126 girls), where 30 students (12.7%) were diagnosed as ADHD. The dietary habit score of the ADHD group was significantly lower than that of the normal group. In particular, the ADHD group had lower dietary scores in consuming daily breakfast, diverse foods, fruit and milk than those in the normal group. Meanwhile, the daily intake frequency of instant noodle (ramyeon) was significantly higher in the ADHD group than that in the normal group. The mean caffeine intake of the students was 42.95 mg and the proportion of students consuming more than the ADI (acceptable daily intake) was 11.8%. The caffeine intake of ADHD group (63.63 mg) tended to be higher than that of the normal group (39.95 mg); however, it was not significantly different. The ADHD score of the students was negatively related with the dietary habit score (r = -0.279, p < 0.01) but positively related with caffeine intake (r = 0.164, p < 0.05). The dietary habit score had a negative relationship with caffeine intake (r = -0.180, p < 0.01) and a positive relationship with height (r = 0.195, p < 0.01). Caffeine intake had a negative relationship with the height of the students (r = -0.171, p < 0.05). In conclusion, ADHD in children was related to poor dietary habit and high caffeine intake.

Purpose: Attention deficit hyperactivity disorder (ADHD) is a common disorder in school-aged children. Patients with restless legs syndrome (RLS) often present with ADHD symptoms and vice versa. This study was the first to attempt to identify the prevalence of RLS and sleep problems in children with ADHD in Korea. Methods: Patients diagnosed with ADHD were asked to complete a sleep questionnaire. The sleep questionnaire included items to help identify the presence of four typical symptoms that are used as diagnostic criteria for RLS. Results: A total of 56 patients, including 51 boys and 5 girls (mean age, 10.7 years old) participated. Of these, 24 complained of pain, discomfort, or an unpleasant sensation in the legs. Based on the RLS diagnostic criteria, 2 patients were diagnosed with definite RLS and 4 with probable RLS. There were no significant differences in age, medication dosage, or neuropsychological test scores between the patients with and without RLS symptoms. Conclusion: Approximately 42.9% of patients with ADHD presented with RLS symptoms and 7.1% of these were diagnosed with RLS. Patients with ADHD also experienced various other sleep disorders. Thus, appropriate assessment and treatment for sleep disorders in patients with ADHD is essential.

Objectives : The aim of the present study was to examine whether anxiety and depression of children and mothers were associated with the children's medically unexplained somatic symptoms in attention-deficit/hyperactivity disorder(ADHD). Methods : 83 clinic-referred boys with ADHD and 52 boys without ADHD were included in this study. The frequency of the medically unexplained somatic symptoms, such as general-ache, headache, nausea, eye problems, skin problems, abdominal pain, vomiting was evaluated using the somatic symptom domain of the Child Behavior Checklist(CBCL). Children's anxiety and depression were evaluated using Kovacs Children's Depression Inventory(CDI) and Spielberger's State-Trait Anxiety Inventory(STAI) for children. Maternal anxiety and depression were measured by Spielberger's State-Trait Anxiety Inventory(STAI) and Beck's Depression Inventory(BDI). Stepwise linear regression analysis was used to examine the hypothesis. Results : Score of maternal state anxiety affects the T score of the somatic symptom domain in CBCL significantly(adjusted $R^2$=0.057 ; p=0.026). Conclusion : The frequency of medically unexplained somatic symptom of children perceived by mothers was associated with the high level of maternal state anxiety in ADHD. Frequent maternal report of the children's somatic symptom may be a warrant for the evaluation and management of the maternal state anxiety in ADHD.

Objectives : The aim of this study was to investigate whether and how the symptoms of adult attention deficit hyperactivity disorder (ADHD) affect the stress and depressive symptoms in Korean soldiers. Methods : Data were collected on 131 subjects through self-report using the Korean Adult Attention-Deficit/Hyperactivity Disorder Scale (K-AADHDS), Center for Epidemiological Studies Depression Scale (CES-D), Korean Wender Utah Rating Scale (K-WURS), and the Brief Encounter Psychosocial Instrument (BEPSI-K). Student t-tests, Pearson Correlation, Logistic regression, and Path analysis were performed. Results : The scores related to adult ADHD symptoms on the K-AADHDS and K-WURS were correlated with stress scores on the BEPSI-K (r=0.529, p<0.001 and r=0.484, p<0.001) and with depressive symptoms on the CES-D (r=0.686, p<0.001 and r=0.628, p<0.001). Scores related to adult ADHD on the K-AADHDS were the most significant risk factors for stress (O.R=1.198, 95% CI=1.104-1.299), and depressive symptoms (O.R=1.306, p95% CI=1.112-1.534). Path analysis on depressive symptoms showed that adult ADHD symptoms affected stress and depressive symptoms. Conclusion : The results suggest that it may be important to consider the evaluation and treatment of adult ADHD in soldiers. Prospective studies with larger numbers of subjects are warranted to further explore the relevance of the present results.

Purpose: In this study differences in behavioral problems between children at risk for Attention Deficit Hyperactive Disorder (ADHD) and normally developing children were identified. Further, relationships between parental stress, depression, and child behavioral problems according to ADHD symptoms were explored. Methods: Participants were 222 elementary school children and their parents. The ADHD risk group was determined by the Korean-ADHD Rating Scale. Data were collected using the Korean-ADHD Rating Scale, Korean version of Child Behavior CheckList (K-CBCL), Parenting Stress Index, and Beck Depression Inventory. Data were analyzed using t-test, Pearson correlation coefficients, and regression analysis. Results: 1) The ADHD risk group showed higher levels of behavioral problems, parenting stress, and maternal depression than the normal group. 2) There were significant relationships between ADHD scores and parenting stress (r=.66), maternal depression (r=.35), internal behavioral problems (r=.47), and external problems (r=.55), but, ADHD risk scores were negatively correlated with social competence (r=-.40). 3) The regression analysis revealed that ADHD levels affected the child's internal behavioral problems, mediated by maternal depression ($\beta$=.29, p<.001). Conclusion: The study results show that higher risk scores for ADHD indicate a significant effect for behavioral problems. Also, parenting stress and depression influence child's behavioral problems. These results suggest that identification of children at risk for ADHD and development of parental education programs would contribute to the prevention of behavioral problems and aggravation of the ADHD symptoms.

Introduction : Attention-deficit hyperactivity disorder (ADHD) was a newly coined term for a disease that existed prior to its naming in the mid 20th century. The issue about whether ADHD is a new disorder or merely a new name for an existing disorder is still controversial. The authors tried to find the clues to the answer for this question through reviewing historical documents for traces of ADHD. Contents : We could find literatures and medical records that contain possible ADHD symptoms. In particular, in 1845, Heinrich Hoffmann's 'fidgety Philip' or 'Johnny Look-in-the-air' nearly satisfies today's criteria for ADHD. Methylphenidate was approved as a promising chemical for inattention in 1957 before the establishment of the concept of ADHD. In 1968, ADHD was first officially introduced as "Hyperactivity Reaction of Childhood" by DSM-II. In 1980, DSM-III, 'Attention Deficit Disorder (ADD)' was adopted as an official diagnostic term and changed to 'ADHD' since the creation of DSM-III-R in 1987. Conclusion : As stated above, ADHD has existed since long ago and became familiar via an advanced diagnostic system and therapeutic options.

Objectives: The aim of the current study is to test for the association of DRD4 exon III VNTR polymorphism with attention-deficit hyperactivity disorder(ADHD) in Korean children population. Methods: 113 Korean children with ADHD, 102 parents, and 133 control subjects participated with the current study. The distribution of genotypes and alleles of DRD4 exon III VNTR in children with ADHD was compared with that in control subjects. In addition, 69 children with ADHD and their parents were analyzed using the transmission disequilibrium test(TDT). Results: We could not find any significant differences in the distribution of genotypes and alleles at DRD4 exon III VNTR polymorphism between children with ADHD and control subjects. In addition, there was no preferential transmission of long allele of DRD4 exon III VNTR polymorphism. Conclusion: These results suggest that DRD4 is not associated with ADHD in Korean children population.

Purpose: The purpose of this study was to use meta-analysis to examine recent domestic articles related to attention deficit hyperactivity disorder (ADHD) in school-age children. Methods: After reviewing 213 articles published between 1990 and 2009 from and cited in RISS, KISS, and DBpia, the researchers identified 24 studies with 440 research variables that had appropriate data for methodological study. SPSS 17.0 program was used. The outcome variables were divided into five types: Inattention, hyperactive impulsive, intrinsic, extrinsic, and academic ability variables. Results: Effects size of overall core symptoms was 0.47 which is moderate level in terms of Cohen criteria and effects size of overall negative variables related ADHD was 0.27 which is small level. The most dominant variable related to ADHD was obtained from hyperactive-impulsive (0.70). Also academic ability (0.45), inattention (0.37), and intrinsic variables (0.29) had a small effect whereas extrinsic variables (0.13) had little effect on descriptive ADHD study. Conclusion: The results reveal that ADHD core symptoms have moderate effect size and peripheral negative variables related ADHD have small effect size. To improve the reliability of the meta-analysis results by minimizing publication bias, more intervention studies using appropriate study designs should be done.
