Objectives : Children with attention-deficit hyperactivity disorder (ADHD) have been shown to display more inhibitory deficits and executive function deficits. This study investigated the treatment effects of neurofeedback (NF) training on executive function by comparing the results of neuropsychological tests of the trained children at pre- and post-training. Methods : Fifteen children with ADHD, aged 6 to 14 years, participated in the study. The NF treatment consisted of slow cortical potential (SCP) training and these sessions took place once a week. The ADHD children performed 20 sessions of NF training within 6 months. Pre-training and post-training assessments encompassed Continuous Performance Test (CPT), Stroop Test, Children's Color Trails Test I&II (CCTT) and Wisconsin Card Sorting Test (WCST). Results : Patients receiving NF training showed significant improvement in visual commission error and standard deviation of auditory response time on CPT ; and total errors on WCST. But there was no significant improvement in the Stroop test and CCTT. Conclusion : SCP training using NF improves the self-regulatory capacities and impulsivity in ADHD patient, especially impulsivity in visual stimulation tasks. This study showed evidence of clinical efficacy of NF on executive function in ADHD.

Purpose: The aim of this study was to identify the effects of a newly developed instructional coaching program regarding Attention Deficit Hyperactivity Disorder (ADHD) for teachers. Methods: Seventy teachers participated in this study involving a nonequivalent control group and a pretest-posttest design. The instructional coaching program consisted of eight 60-minute sessions. The program was developed through a theoretical development program involving six steps. To evaluate the effects of the program, data were collected through self-report questionnaires including the Knowledge Scale of Attention Deficit Disorder, Attitude Scale of Primary School Teachers Experiencing Students with ADHD, Practice Scale of Educational Intervention Activity, and the Korean ADHD Rating Scale. Data were analyzed with an independent t test, a chi-square test, and an ANCOVA using SPSS WIN version 20. Results: The intervention program consisted of 3 sectors, 8 subjects, and 24 content items. The experimental group showed a significant improvement in attitudes toward ADHD (F=22.83, p<.001). In addition, teacher's knowledge regarding ADHD (F=7.16, p=.010) and the implementation of instructional interventions (F=4.29, p=.043) improved. Further, teachers reported a reduction in children's ADHD-related behavior (F=4.34, p=.041). Results showed that the coaching program made a positive contribution to teaching skills and understanding of school-age children with ADHD. Conclusion: The instructional coaching program was well structured and significantly improved not only teachers'attitudes, knowledge, and teaching skills but also the behavior of children with ADHD in class. Therefore, the program is recommended as a means of facilitating teaching and managing children with ADHD in class.

Objectives : Attention-deficit hyperactivity disorder (ADHD) and Asperger's disorder (AD) in children are associated with attentional problems, impulsivity, hyperactivity, and difficulties with social interactions. Pharmacological treatment may alleviate symptoms of ADHD, but seldom solves difficulties with social interactions. Social skills training (SST) may assist in improving their social interactions. We examined the effects of SST on children's social competences, general behavior, and ADHD symptoms. Methods : Thirty four children, aged 7 to 12 years, participated in the cognitive behavioral SST program once a week at the outpatient division of child-adolescent psychiatry. SST was composed of 24 sessions (ninety minutes) for 6 months. Twenty-five children were diagnosed with ADHD, and 9 children were diagnosed with AD. Parents of the children rated Korea-Child Behavior Checklist (K-CBCL), Conner's rating scales, Korean-ADHD Rating Scale (K-ARS), Social Skill Rating System (SSRS), and Matson's Social Skill Rating Scale as an evaluation of the treatment effect, before the first session and after the final session of the training. Results : The ADHD group showed significantly increased scores of social and social competence of CBCL and SSRS. Further, scores of externalizing problems of CBCL, CRS, and ARS were significantly decreased. The Asperger's group showed significantly increased scores of social competence of CBCL, SSRS, and MESS. There was a significant difference of the improvement in CBCL's school and total behavior problem score, CRS between drug change group and no drug change group. Conclusion : The result of this study suggests that SST is effective in improving social skills for children with ADHD and AD. In addition, SST has shown its effectiveness in treating attentional problems for children with ADHD. To prove objective usefulness of SST, further studies with a more structured design and long-term duration along with a sufficient number of AD participants will be necessary.

Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by hyperactivity, inattention, and impulsiveness. Current estimates suggest that 4-12% of school age children are affected by ADHD, which hampers proper social relationship and achievements in school. Even though the exact etiology of the disorder is still in the middle of active investigation, the availability of pharmacological treatments for the disorder suggest that at least the symptoms of ADHD are manageable. To develop drugs with higher efficacy and fewer side effects, it is essential to have appropriate animal models for in vivo drug screening processes. Good animal models can also provide the chances to improve our understanding of the disease processes as well as the underlying etiology of the disorder. In this review, we summarized current animal models used for ADHD research and discussed the point of concerns about using specific animal models.

Attention deficit hyperactivity disorder(ADHD) is one of the most common childhood-onset psychiatric disorders. It is distinguished by symptoms of hyperactivity, inattention, and impulsivity. The etiology of ADHD is unknown, and the disorder may several different causes. The pharmacotherapy most widely used for ADHD occasionally gives rise to ill effects. The studys of ADHD were approached from the viewpoint of medicine and pedagogics, but it is rare from the viewpoint of the Korean Medicine. So, we searched for the studies on ADHD of Chinese Traditional Medicine(TCM) in last eight years(1995-2002). In TCM, ADHD was placed under the category of 'wind(風)-one of the five pathogenic factors', 'insomnia(失眠)', 'forgetfulness(健忘)' and 'restlessness(躁動)', etc. Jang and Bu(the internal organs; 臟腑) related with the differentiations of syndrome about ADHD were liver(肝), heart(心), spleen(脾), kidney(腎) and gallbladder(膽). Among them, liver(肝), kidney(腎) and spleen(脾) were important. The herbal medicines used in ADHD had the effects of spirit-calming(安神), orifices-opening(開竅), Eumyang-balance(陰陽平衡). And acupuncture therapy, ear-acupuncture therapy and dietary treatment, etc. were used in the treatment of ADHD. We expect that this review about ADHD in TCM help the clinical study of ADHD in Korean Medicine.

Objectives: This study investigated quality of life in Korean juvenile inmates with attention-deficit/hyperactivity disorder (ADHD) and the impact of behavioral and emotional problems on quality of life. Methods: In total, 200 inmates were evaluated using the Korean version of the Mini-International Neuropsychiatric Interview (K-MINI) and the Korean version of the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime (K-SADS-PL-K). We extracted the inmates with ADHD and evaluated their quality of life, behavioral problems, and emotional problems with the Pediatric Quality of Life Inventory (PedsQL) and the Korean Youth Self Report (K-YSR) scale. Descriptive statistics, Pearson correlation analysis, and multiple regression analysis were conducted. Results: Among the 200 total inmates, 68 were diagnosed with ADHD by the K-SADS-PL-K. Most of the correlations between PedsQL scores and K-YSR items were significant. Multiple regression analysis showed that PedsQL could be predicted by affective problems (among the DSM-oriented scales of the K-YSR) and attention problems (among the syndrome scales of the K-YSR). Conclusion: Our results demonstrate that, among juvenile inmates with ADHD, quality of life was negatively correlated with most behavioral and emotional problems. Meanwhile, the significant influence of affective and attention problems on inmates' quality of life suggests the necessity of comprehensive treatments for this group.

Objectives The objectives of this study is to investigate the characteristics of Attention-deficit/hyperactivity disorder (ADHD) pattern identification based on the survey of frequencies of symptoms and signs according to the pediatricians and psychiatrists in Korean Medicine. Methods Eleven pediatricians and fourteen psychiatrists participated in this study. 38 symptoms and signs of 4 ADHD pattern identifications (Kidney yin deficiency and liver yang ascendant hyperactivity 腎虛肝亢, Dual deficiencies in the heart and spleen 心脾兩虛, Phlegm-fire harassing the heart 痰火擾心, Spleen weakness and liver energy preponderance 脾虛肝旺) were used to evaluate the frequencies of ADHD. The differences in frequencies of symptoms and signs amongst ADHD pattern identifications, and the correlations between them were analyzed. Results There were significant differences in the frequencies of symptoms and signs between each pattern identification. Dual Deficiencies in the Heart and Spleen 心脾兩虛 is negatively related with hyperactivity and impulsivity, and positively related with inattention. Phlegm-fire Harassing the Heart 痰火擾心 is positively related with hyperactivity and impulsivity, and negatively related with inattention. Conclusions The results of the characteristics of ADHD pattern identifications from the survey analysis could be used in the clinical practices of ADHD as well as to improve the ADHD pattern identification questionnaire.

Objectives : Cognitive dysfunction, including inattention, is often observed in patients with depression. Inattentive symptoms in patients with depression is similar to those among attention deficit/hyperactivity disorder (ADHD) patients. It is important to diagnose the two diseases accurately, because the treatment varies depending on the cause of inattention. This study aimed to investigate the coexistence rate of ADHD and the correlation between ADHD symptoms and depression in patients with depression. Methods : Participants in this study were 158 outpatients presenting with depression, who visited the psychiatric department from March 2015 to July 2018. Participants divided into a depression and a non-depression group according to the Korean version of the Center for Epidemiological Studies-Depression Scale (CES-D) score and were administered the following : a sociodemographic variables form (age, sex, academic background, occupation), the self-reporting test for adult ADHD (Adult Attention Deficit/Hyperactivity Disorder self-report scale-V 1.1; ASRS V1.1), and the Korean version of the Connors adult ADHD rating scale (K-CAARS). Descriptive statistical analysis, crossover analysis, t-tests, and Pearson's correlation coefficient were conducted on the data. Results : The coexistence rate of adult ADHD symptom was as high as 36.7% in patients with depression (p<0.001). In K-CAARS, the depression group (Inattention=1.80, Hyperactivity=1.92, Impulsivity=1.56, Self-concept=2.06) showed higher average scores on ADHD symptoms than the non-depressive group (Inattention=1.28, Hyperactivity=1.25, Impulsivity=1.09, Self-concept=1.42, p<0.001). Conclusions : This study confirmed that ADHD symptoms coexist in the depression group. When evaluating the symptoms of patients who complain of depression, it is suggested that they should be accurately diagnosed and appropriately treated with interest to the coexistence of ADHD symptoms and the possibility for ADHD diagnosis.

Objective: Many drug or non-drug therapies are reported to be effective in reducing the severity of attention deficit/hyperactivity disorder (ADHD). The aim of this study was to assess the effect of color and pattern on the severity of ADHD in young ADHD patients. Method: We randomly assigned 30 children into two groups and had them participate in 15-minute block play sessions once in a week. The experimental group used blocks with green (3G, Munsell color system) circle patterns on them, while the control group played with plain white blocks. We also provided a set of playing cards with the corresponding patterns. This trial continued for 4 weeks and 29 children (96.7%) completed. The primary outcome measurement was the ADHD rating scale-IV and was evaluated on every visit. Results: After the trial, ADHD score decreased in both groups but not significantly ($34.4{\pm}8.0$ to $30.0{\pm}4.3$; $34.0{\pm}6.0$ to $30.3{\pm}3.2$). However, there were significant differences in 4 items of ADHD rating scale between the two groups. These consisted of 3 inattention (Q3, Q7, Q15) and 1 hyperactivity-impulsivity (Q12) items and the reduction between the first and final visits was significant (p=0.0240, p=0.0498, p=0.0237 and p=0.0012 respectively). Conclusion: Repeated exposure to a green circle pattern might not influence the total score of ADHD rating scale but reduced 3 inattention items and 1 hyperactivity-impulsivity significantly in children with ADHD. Proper visual stimuli are partially helpful for pediatric ADHD.

This study investigated the correlation between consumption of sugar intake by fifth grade students in primary schools and development of Attention Deficit Hyperactivity Disorder (ADHD). A total of 107 students participated, and eight boys and one girl (8.4% of the total) categorized as high risk for ADHD according to diagnostic criteria. There were significant differences in the occupations and drinking habits of the respondents' fathers between the normal group and risk group. In a comparison of students' nutrition intake status with daily nutrition intake standards for Koreans, students consumed twice as much protein as the recommended level, whereas their calcium intake was only 60% of the recommended DRI (dietary reference intake). Regarding intake volume of vitamin C, the normal group posted 143.9% of the recommended DRI, whereas the risk group showed only 65.5% of the recommended DRI. In terms of simple sugar intake from snacks, students in the normal group consumed 58.4 g while the risk group consumed 50.2 g. These levels constituted 12.5% of their total daily volume of sugar intake from snacks, which is higher than the 10% standard recommended by the WHO. In conclusion, children who consumed less sugar from fruit snacks or whose vitamin C intake was less than RI was at increased risks for ADHD (P < 0.05). However, no significant association was observed between total volume of simple sugar intake from snacks and ADHD development.
