Objectives: Oppositional defiant disorder (ODD) is often comorbid with other psychiatric disorders in childhood. This study aimed to investigate comorbid psychiatric symptoms and associated factors in elementary school children with symptoms of ODD. Methods: The participants consisted of 205 mother-offspring pairs. Psychiatric symptoms were measured using the Diagnostic Predictive Scales and Korean Child Behavior Checklist. Psychiatric comorbid symptoms were compared between children with ODD symptom and those without ODD symptom. Multivariate logistic regression analysis was used to estimate the odds ratio of psychiatric symptom on ODD. Results: ODD group had a significant association with internalizing and externalizing problem (p=0.001, p<0.001, respectively). ODD group were more comorbid with anxiety disorder, depressive disorder, attention-deficit/hyperactivity disorder, and conduct disorder. Among psychiatric disorder, generalized anxiety disorder (GAD) (adjusted odds ratio [AOR]=18.620, p<0.001) and conduct disorder (AOR=9.529, p=0.014) were associated with ODD symptom. Conclusion: These findings suggest that children with ODD symptom had significantly higher rates of comorbid psychiatric symptoms. And GAD and conduct disorder are related to ODD symptom.

Electroencephalography (EEG) measures neural activation due to various cognitive processes. EEG and event-related potentials (ERPs) are widely used in studies investigating psychopathology and neural substrates of psychiatric diseases in children and adolescents. The present study aimed to review recent ERP studies in child and adolescent psychiatry. ERPs are non-invasive methods for studying synaptic functions in the brain. ERP might be a candidate biomarker in child-adolescent psychiatry, considering its ability to reflect cognitive and behavioral functions in humans. For the EEG study of psychiatric diseases in children and adolescents, several ERP components have been used, such as mismatch negativity, P300, error-related negativity (ERN), and reward positivity (RewP). Regarding executive functions and inhibition in patients with attention-deficit/hyperactivity disorder (ADHD), P300 latency, and ERN were significantly different in patients with ADHD compared to those in the healthy population. ERN showed meaningful changes in patients with anxiety disorders, such as generalized anxiety disorder, separation anxiety disorder, and obsessive-compulsive disorder. Patients with depression showed significantly attenuated RewP compared to the healthy population, which was related to the symptoms of anhedonia.

Objectives: This study aimed to examine the trend in diagnostic prevalence of psychiatric disorders in children and adolescents. Methods: Individuals aged 0-18 years were included in the study based on the National Health Insurance Claims Data. To investigate the trends in diagnosis and diagnostic prevalence of psychiatric disorders reflecting the decrease in the birth rate, data were analyzed from 2010 as a reference year to 2015. Results: The number of patients diagnosed with psychiatric disorder decreased annually, from 23,412 on 2010 to 18,821 on 2015. The most common disorder was hyperkinetic disorder in male and depressive episode in female. Although there was no significant change in overall diagnostic prevalence rate of psychiatric disorders, age groups <10 years and some disorders had significant changes in prevalence rate. This study classified the diagnostic prevalence by age into two unique patterns: group in which the diagnosis rate increases with age and group in which the diagnosis rate peaks at a certain age and then decreases. Conclusion: Diagnostic prevalence of psychiatric disorders was different according to age and sex. These patterns should be reflected in the formulation of policies related to mental health and in medical practice for pediatric patients. It is urgent to identify how these patterns change in young adults.

The purpose of this review is to examine the clinical use of functional near-infrared spectroscopy (fNIRS) in children and adolescents with psychiatric disorders. Many studies have been conducted using objective evaluation tools for psychiatric evaluation, such as predicting psychiatric symptoms and treatment responses. Compared to other tools, fNIRS has the advantage of being a noninvasive, inexpensive, and portable method and can be used with patients in the awake state. This study mainly focused on its use in patients with attention-deficit/hyperactivity disorder and autism spectrum disorder. We hope that research involving fNIRS will be actively conducted in various diseases in the future.

Objectives: The prevalence of psychiatric disorders among young adults is different from that among younger or older age groups because of biological and environmental changes. The purpose of this study was to analyze the diagnostic distribution of psychiatric disorders in 19-30-year-old Koreans based on their age and gender using data from the Korean National Health Insurance Service (NHIS). Methods: From the 2011 medical claims sample data of NHIS of 1,375,842 people, we extracted the data of 221,038 people aged 19-30 years, including 106,232 (48.1%) men and 114,806 (51.9%) women. We evaluated the overall changes in the diagnostic distribution of psychiatric disorders over a 3-year period. Results: The diagnostic frequency in women was 13,627 (59.0%), which was significantly higher than that in men. "Other anxiety disorders" was the most common psychiatric disorder in both genders, followed by depressive episodes, somatoform disorders, "other neurotic disorders," and nonorganic sleep disorders. In men, attention-deficit/hyperactivity disorder or intellectual disabilities were not among the top 10 disorders. In women, no significant changes in major psychiatric disorders were seen over the 3-year period. Conclusion: These results reveal the trends of diagnostic distribution of mental illnesses depending on the development, particularly in young adulthood. It is necessary to identify whether such trends are due to biological or environmental factors, aging processes, or complex influences.

Objectives : The aim of this study was to examine the relationship between internet game addiction and psychiatric symptoms. Methods : A total of 447 adolescents who were recruited from a child and adolescent psychiatric clinic of university hospital completed a self-report questionnaire consisting of Korean Internet Addiction Self-scale (K-scale), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Korean-Attention-Deficit Hyperactivity Disorder Rating Scale (K-ARS), and Adolescent Happiness Index (AHI). They were classified into three internet user groups, non-addicted group (below or equal to 94), potential risk group (95 to 107) and high risk group (above or equal to 108) according to K-scale total score. Results : Significant mean differences in BDI, BAI, K-ARS, and AHI scores were observed among the three groups. The BDI, BAI and K-ARS scores showed positive correlation with K-score. The AHI score showed negative correlation with K-score. Conclusion : Findings of this study suggest that depression, anxiety, inattention, hyperactivity/impulsivity, and happiness are associated with internet game addiction.

본 연구에서는 여러 소아정신과 장애를 보이는 아동들의 모(母)의 MMPI 프로파일 유형을 비교, 분석함으로써 모(母)의 성격 특성이나 심리적 문제와 아동의 정신과적인 장애간의 관계를 알아보고자 하였다. 서울대학 병원 소아정신과를 방문한 아동들을 그들이 보이는 문제 행동의 유형에 따라 내면화중상 집단(n=35), 외현화증상 집단(n=35), 발달 장애 집단(n=21)으로 분류한 후, 이러한 임상 집단의 모(母)들과 정상 아동 집단의 모(母)들(n=20)이 본 연구의 피험자로 사용되었다. 4집단의 모(母)들의 MMPI결과를 5가지 프로파일 유형(정상, 우울증, 불안 장애, 신체화 장애, 성격장애)으로 분류하여 아동의 진단과 틀의 MMPI 프로파일 유형간의 관계를 알아본 결과, 아동의 진단과 모(母)의 MMPI프로파일 유형간에 유의미한 관계가 있었다. 정상 아동들의 모(母)는 대부분 정상 프로파일을 보인 반면, 임상 집단의 모(母)들은 아동의 진단과는 관계없이 통계적으로 유의미한 수준에서 우울증을 시사하는 프로파일을 많이 보였고, 외현화증상 집단의 모(母)들이 내면화 증상 집단의 모(母)보다 더 불안 장애 프로파일을 많이 보였다. 이러한 결과는 아동의 정신과적인 문제와 모(母)의 심리적 장애간에 관련이 있음을 시사하는 것으로, 아동과 모(母)의 부정적인 상호작용이 서로의 심리적인 적응에 해로운 영항을 주었을 가능성이 논의되었고, 정신병리에 대한 연구에서 부모가 아동의 적응에 미치는 영향뿐만 아니라 아동의 문제가 모(母)의 심리적 적응에 미치는 특별한 영향도 살펴볼 필요가 있음이 시사되었다.

Present study reviewed various standardized neuropsychological assessment methods for children that are widely used in Korean child-psychiatric clinic settings to evaluate neurological problems, especially soft neurological signs that could not be identified by neurological techniques like CT, MRI. The characteristics of those neuropsychological test responses in children with psychiatric disorders that neurological factors are thought to play more important role than psychological factors in their etiology were examined. It is more important and required to establish the developmental norms for interpreting the results of neuropsychological tests and for identifying the signs of brain damage in case of children than adults. There are many difficulties in diagnosing brain dysfunction and conducting research for neurological problems in psychiatric disordered children due to lack of the standardized Korean version of neuropsyhological test for children, Therefore, several issues on developing the Korean version of neuropsyhological tests for children were discussed.

Many neurologic disorders manifest as psychiatric symptoms. Anti-N-Methyl-D-Aspartate (NMDA) receptor encephalitis is an autoimmune disease of the brain characterized by numerous neurological and psychiatric features. Despite being rare, its prevalence is rapidly increasing and early management is critical in ensuring successful and sustainable recovery. Therefore, the illness should be considered as a differential diagnosis when clinically assessing patients. This report presents a case of a female child who was hospitalized for acute psychiatric manifestations, which was later confirmed as anti-NMDA receptor encephalitis. She recovered relatively successfully after combined neurological and psychiatric treatment. This report provides information on the clinical course of early onset anti-NMDA receptor encephalitis, including treatment strategy and prognosis.
