Purpose: This study translated the developmental coordination disorder questionnaire'07 (DCDQ'07) into Korean and investigated the psychometric properties of the Korean DCDQ (DCDQ-K) using validation processes. Methods: The subjects were 300 parents with typically developing children aged 5-15 years (162 girls and 138 boys, mean age 9.24 years, SD 2.59) across the country. To develop the Korean DCDQ, a forward-backward-original author feedback-panel meeting-pilot study with parents was done. The internal consistency, test-retest reliability performed two weeks apart, content validity, discriminative validity, convergent validity, and constructive validity were examined with the pre-version of the DCDQ-K. Results: Approximately 15.33% of the subjects were probably shown DCD using DCDQ-K. Significant differences in age and province were observed in the DCDQ-K total score. The reliabilities and validities were good in the DCDQ-K. Conclusion: The DCDQ-K is a reasonable screening tool for DCD children.

Objectives : The purpose of this study was to investigate the effectiveness of a day-hospital treatment program designed to help development of children with pervasive developmental disorder (PDD) and mental retardation (MR). Methods : Retrospective review of the charts of 32 children (28 with PDD, 4 with MR), who participated in a day-hospital treatment program of Seoul Metropolitan Eunpyeong Hospital, from October 2008 to February 2012, was conducted. Development level of each patient was evaluated according to the Psycho-Educational Profile-Revised (PEP-R), Social Maturity Scale (SMS), and Childhood Autism Rating Scale (CARS). Evaluation was done at two points, before participation and after 1 year participation. Results : Children who participated in the day-hospital treatment program showed significant improvement in all categories of PEP-R, SMS, and CARS. Conclusion : Day-hospital treatment program is effective for helping development of children with PDD and MR.

Objectives : The purpose of this study was to examine the prenatal, perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD), compared to unaffected siblings (SIB), and typically developing children (TC). Methods : Subjects with ADHD, their SIB, and TC were recruited from the child psychiatry outpatient clinic of the Asan Medical Center Children's Hospital. The parents of the children completed questionnaires on perinatal and developmental risk factors. Results : Fifty-eight subjects with ADHD (41 boys, $7.7{\pm}1.3years$), 21 SIB (8 boys, $8.2{\pm}1.8years$), and 22 TC (8 boys, $8.5{\pm}2.1years$) were included. The ADHD group showed higher rates of maternal stress during pregnancy than the SIB group (p=.002), and the ADHD group showed higher rates of familial psychiatric history than the TC (odds ratio, 8.76 ; 95% confidence interval, 1.69 to 45.45). Conclusion : These findings suggest that among perinatal and developmental factors, maternal stress during pregnancy contribute to the development of ADHD. Future prospective studies will be needed in order to determine the causal relationship between perinatal risk factors and development of ADHD.

Objectives:The objective of this study was to examine the perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD) diagnosed with a structured interview among Korean children. Methods:The current study included 924 children (6-15 years) recruited from schools in five Korean cities or a child psychiatry outpatient clinic of Seoul National University Children's Hospital. The parents of the children completed the structured diagnostic interview for attention-deficit hyperactivity disorder, as well as questionnaires on perinatal and developmental risk factors. Results:Preterm delivery, severe maternal stress during pregnancy, change in primary care taker during the first three years, postpartum depression, and delayed first sentence showed a significant association with ADHD diagnosis. Conclusion:These findings suggest that perinatal and developmental factors contribute to development of ADHD in Korean children. Conduct of future research using a prospective design is needed in order to identify the causal relationship between observed risk factors and development of ADHD.

Objectives: Among the many intervention programs for children with autism spectrum disorder (ASD), the Early Start Denver Model (ESDM) is one of the few approaches that has succeeded in demonstrating clinical efficacy in randomized control trials. Here, we investigate the clinical efficacy of ESDM intervention in young children with ASD in a community setting within Japan. Methods: All subjects were children with ASD who received ESDM intervention during the study period. Each ESDM session lasted 75 min and occurred once per week for at least 12 weeks. The outcome measures consisted of the Kyoto Scale of Psychological Development (K-test), Aberrant Behavior Checklist-Japanese version (ABC-J), and the Clinical Global Impression-Severity scale (CGI-S). Results: Twenty-seven subjects (29.4±6.4 months old) received ESDM intervention that lasted for 8.0±2.6 months on average. The score on Language and Social developmental quotient on the K-test increased significantly after the intervention. The total scores on the ABC-J and CGI-S significantly decreased after completion of the ESDM intervention. Conclusion: Our results suggest that ESDM intervention could reduce the severity of distinct clinical features of ASD, such as impairments in social interaction and communication assessed by the K-test, and maladaptive behavior rated by the ABC-J and CGI-S. We believe that the ESDM adapted to each institution might become one of the standard options for children with ASD in Japan.

CCCTC-binding factor (CTCF) is a transcriptional regulator that binds to a complex DNA motif in various orientations and plays a crucial role in regulating gene expression, chromatin restructuring, and developmental processes. Mutations in the CTCF are associated with neurodevelopmental disorders. Here we report the first Korean case with a de novo heterozygous variant in the CTCF (c.1025G>A; p.Arg342His). She showed global developmental delay, failure to thrive, and dysmorphic face, which are phenotypes consistent with previous reports in the autosomal dominant intellectual developmental disorder 21 (MIM 615502). She also showed clinical features not previously reported, such as antral web and tracheobronchomalacia. Our case follows suit and expands understanding of this rare disorder by reporting common features and, on the other hand, unreported concomitant congenital anomalies.

본 논문은 주의산만이나 과잉운동을 주소로 대학병원 정신과에 내원한 5세에서 13세 사이의 환아들을 대상으로 인구학적 특성과 주진단 및 공존질병에 대해서 조사하였고, 그 중에서 주의력결핍 과잉운동장애(ADHD)로 진단 받은 환아들의 인구학적 및 임상적 특성을 조사하였으며, 공존질병이 있는 집단과 ADHD만 있는 집단을 비교 분석하였다. 또한 ADHD군과 외향적장애군 및 내향적장애군 등 세집단간의 임상특성과 심리검사상의 차이를 알아보았다. 주진단은 ADHD가 가장 많았고. 불안장애, 정신지체, 우울증, 반항장애, 발달성언어장애 등의 순이었다. 두 가지 이상의 진단이 내려진 경우가 48.9% 이었고, 부진단으로는 유뇨증, 품행장애, 발달성언어장애 등이 있었다. 주진단을 ADHD로 받은 환아들에서 공존질병이 있는 경우가 55.3%에 달했고. 공존질병은 특수발달장애, 품행장애, 반항장애, 불안장애 등의 순이었다. 순수 ADHD군에 비해서 공존질병 수반군에서는 동작성 지능검사와 연속과제수행검사에서 저조한 수행을 보였다. 외향적장애군은 ADHD군에 비해 지능검사의 상식 소검사 및 같은 그림찾기 검사와 연속과제수행검사에서 수행의 저하를 보였다. 내향적장애군은 ADHD군에 비해 교사 평정척도 점수가 낮았고, 아동행동조사표의 소통불능요인이 높았으며 연속과제수행검사에서는 카드 오류수가 낮았다. 본 연구의 결과를 볼 때 주의산만이나 과잉운동이 주증상으로 나타날 경우 각종 평가 및 신경심리검사도구를 광범위하게 사용하여 ADHD 외에도 외향적 및 내향적장애군 등 다양한 질환을 감별하여야 하며, ADHD 진단을 내리는 경우에도 수반된 공존질병의 유무를 확인하여 이를 치료계획에 반영하여야 할 것으로 생각된다.

The Guarantee of Rights and Support for Persons with Developmental Disabilities Act was enacted and revised in 2014. However, national measures for persons with developmental disabilities remain insufficient. In the film, "Grown Up," director Hyeyoung Jang filmed the daily life of her sister, who has developmental disabilities. She raised not only the issue of institutionalization in people with developmental disabilities in Korea but also the issue of a lack of policies that would be essential to them and their family members. In the future, I hope that as experts, child and adolescent psychiatrists in Korea will pay more attention to the lives of people with developmental disabilities outside the clinic and propose policies to help them and their family members.

Deep learning (DL) is a kind of machine learning technique that uses artificial intelligence to identify the characteristics of given data and efficiently analyze large amounts of information to perform tasks such as classification and prediction. In the field of neuroimaging of neurodevelopmental disorders, various biomarkers for diagnosis, classification, prognosis prediction, and treatment response prediction have been examined; however, they have not been efficiently combined to produce meaningful results. DL can be applied to overcome these limitations and produce clinically helpful results. Here, we review studies that combine neurodevelopmental disorder neuroimaging and DL techniques to explore the strengths, limitations, and future directions of this research area.
