Attention-deficit hyperactivity disorder (ADHD) is a common, childhood-onset, neuropsychiatric disorder with an estimated prevalence of 2-7.6% in Korean children. Although the etiology of ADHD is not well understood, evidence from genetic factor and environmental factor studies suggests that ADHD results from a gene environmental interaction. In the current study, we reviewed the evidence for and clinical implications of the hypothetical roles of organophosphate pesticides, organochlorine pesticides, polychlorinated biphenyls, phthalate, bisphenol, polyfluoroalkyl chemicals, polycyclic aromatic hydrocarbons, mercury, lead, arsenic, cadmium, manganese, tobacco, alcohol as harmful risk factors in the development of ADHD.

In this paper, we propose that college counselors be more knowledgable of adult ADHD symptoms and develop better understandings of subtypes of the disorder. The findings in this study show that college students with different subtypes of ADHD symptoms experience different types of psychological maladjustment as well as different levels of psychological distress. Specifically, combined-type trait group show the highest levels of each of subscale of SCL-90-R among the other groups (i.e., normal, predominant inattentive subtype, hyperactive-impulsive type). Furthermore, combined typed trait group show significantly higher levels of animosity and paranoid ideation than the others. Therefore, college counselors need to provide effective interventions addressing intense emotion and cognitive distortion among college students with ADHD combined symptoms.

Background : The objective of this study was to evaluate the diagnostic efficiency of the Comprehensive Attention Test (CAT) by comparing the results of the continuous performance test (CPT) and the CAT in children and adolescents with attention-deficit hyperactivity disorder (ADHD). Method : A total of 110 children and adolescents with ADHD (mean age : 11.2${\pm}$2.9 years, 76 boys) and 36 children and adolescents without ADHD (mean age : 12.0${\pm}$2.7 years, 25 boys) completed the CAT. We compared the specificity and sensitivity of the CPT and CAT at two different cut-off points via the McNemar test. The areas under the receiver operating characteristic curves (AUC) between the two groups were compared using Medcalc software. Results : The sensitivity and specificity of the CPT were .419 and .806, respectively. The sensitivity of the CAT was .827, which was significantly higher than that of the CPT (p<.001), and the specificity of CAT is .444, which was significantly lower than that of CPT (p<.001). The AUC of the CPT and CAT was .664 and .692, respectively, and there were no significant difference between the two groups on the paired comparison (p=.513). Conclusions : The results of this study suggest that the CAT has moderate specificity and high sensitivity. The CAT can be used as a useful tool to evaluate the neuropsychological function of children and adolescents with ADHD.

Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in childhood. This disorder, in addition to its main symptoms, creates significant difficulties in education, social performance, and personal relationships. Given the importance of rehabilitation for these patients to combat the above issues, the use of virtual reality (VR) technology is helpful. The aim of this study was to highlight the opportunities for VR in the rehabilitation of children with ADHD. This narrative review was conducted by searching for articles in scientific databases and e-Journals, using keywords including VR, children, and ADHD. Various studies have shown that VR capabilities in the rehabilitation of children with ADHD include providing flexibility in accordance with the patients' requirements; removing distractions and creating an effective and safe environment away from real-life dangers; saving time and money; increasing patients' incentives based on their interests; providing suitable tools to perform different behavioral tests and increase ecological validity; facilitating better understanding of individuals' cognitive deficits and improving them; helping therapists with accurate diagnosis, assessment, and rehabilitation; and improving working memory, executive function, and cognitive processes such as attention in these children. Rehabilitation of children with ADHD is based on behavior and physical patterns and is thus suitable for VR interventions. This technology, by simulating and providing a virtual environment for diagnosis, training, monitoring, assessment and treatment, is effective in providing optimal rehabilitation of children with ADHD.

갑상선호르몬 내성증후군(GRTH)과 주의력 결핍-과잉행동장애(ADHD)의 관계는 최근에 매우 연구가 활발히 진행되면서, ADHD환아에서 갑상선 검사를 기본검사로 시행할 것인가 여부가 또한 논란이 되고 있다. 저자는 ADHD 환아뿐 아니라 발달장애 환아에서도 GRTH가 발견될 수 있다는 사항에 주목하여 이들 환자들에서 갑상선 검사를 시행하여 이상 유무를 조사하고, 뚜렷한 이상소견을 보이는 환아들의 임상 양상을 밝혀 앞으로 이들의 가계 연구 및 유전자 연구의 시작을 해보고자 하였다. 총 51명에서 검사가 시행되었고, 이중 T3, T4가 모두 정상범위를 벗어나며, TSH가 정상 혹은 증가된 증례가 모두 11명이었다. 그들의 임상 특성과 진단등을 살펴보고, 앞으로의 방향에 대해 토의하였다.

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 this study was to determine whether children with Tourette disorder (TD) have functional impairment and executive dysfunction in comparison to children with attention-deficit hyperactivity disorder (ADHD) and non-affected controls. Methods : From January 2006 to December 2013, 45 children and adolescents with TD and 50 children and adolescents with ADHD diagnosed at the Soonchunhyang University Bucheon Hospital and 50 non-affected controls were enrolled in this study. Functional impairment of the subjects was assessed using the Child and Adolescents Functioning Impairment Scale (CAFIS), parent and teacher versions. In addition, neuropsychological tests including Stroop color-word Test, Finger windows Test (FWT), and Digit span were administered. Outcomes were compared across the TD, ADHD, and non-affected controls. Results : No difference in CAFIS-parent and CAFIS-teacher results was observed between children with TD and non-affected controls, whereas, children with ADHD showed more impairments relative to non-affected controls in the CAFIS-parent. According to the Stroop color-word Test, FWT, and Digit span, executive function in children with TD did not differ from non-affected controls. Children with ADHD had poorer performance in measures of the Stroop color-word Test compared to children with TD. Conclusion : Children and adolescents with TD but not ADHD were not significantly different from non-affected controls on most measures of functional impairment and executive function. These findings suggest that an education program and intervention for children with TD would be important to reducing the stigma of TD.

Objectives: Previous studies have reported that internet addiction (IA) is associated with attention-deficit/hyperactivity disorder (ADHD) consistently. However, in terms of gender, there are controversial findings. We aimed to investigate the relation between IA and self-acknowledged ADHD traits among female college students in Japan. Methods: The study questionnaire consisted of questions about demographics, Adult ADHD Self-Report Scale-V1.1 Part A (ADHD screener) and Young's Internet Addiction Test (IAT). When four or more items are more frequent than the cut-off on ADHD screener, the subject was categorized into students with a positive ADHD screen. We defined students with total IAT score of 70 and higher as IA. Results: A total number of respondents was 369 (mean age: $19.0{\pm}0.7years$). Seventy-seven subjects were screened positive on ADHD screener (20.9%). Students with a positive ADHD screen scored significantly higher on the IAT ($54.2{\pm}14.2$ vs. $42.5{\pm}11.3$). The rates of IA in students with and without a positive ADHD screen were 18.2% and 1.0%, respectively. Conclusion: Results of this study demonstrated the relation between IA and self-evaluated ADHD traits among female college students in Japan. Appropriate education for students on how to use the internet properly will be necessary to prevent IA.

Attention deficit hyperactivity disorder (ADHD) is characterized by inattention, impulsivity, and hyperactivity. Given high incidence of ADHD, many children with ADHD is likely to present for anesthesia. This case report suggests intramuscular premedication as an alternative method for anesthetic induction. A 9-year-old male patient with ADHD was transferred for dental treatment under general anesthesia. The patient refused to go into dental clinic office. Oral midazolam was given to the patient, however, he was resistant to take midazolam via oral route. Instead, we administer midazolam and ketamine via intramuscular route. After less than 10 miniutes, the patient became drowsy and was transferred to dental chair. Intravenous access and mask inhalation was possible. The patient received dental treatment under general anesthesia and recovered in a non-complicated way. In this case, intramuscular sedation with midazolam and ketamine was used as a premedication in highly uncoopearive patient refused to take oral sedative medication.
