본 연구는 약물의 작용기전이 각기 다른 methylphenidate와 imipramine을 투여하여 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애(過剩運動障碍)(attention deficit-hyperactivity disorder : ADHD)아동에서 부모와 교사의 평정척도(平定尺度)로 행동변화를 그리고 신경심리학적검사(神經心理學的檢査)로 주의력(注意力)과 인지기능(認知機能)을 측정하여 두 약물이주는 영향이 행동영역(行動領域)과 인지기능(認知機能)에서 어떻게 다르게 나타나는 지를 비교검토해 본 것이다. 저자들은 미국정신의학회 정신질환 진단기준편람 개정3판(DSM-III-R)에 의거하여 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애(過剩運動障碍)로 진단받은 생후 만 5년 6개월부터 12년 1개월사이의 남아 30명을 대상으로 이들의 임상적${\cdot}$의학적 특성을 조사하고, 지능검사를 포함한 신경심리학적검사(神經心理學的檢査)를 시행한 뒤, 부모(父母) 및 교사용(敎師用) 평정척도(評定尺度)로 이들의 행동을 평가하였다. 그리고 평가된 아동을 무작위로 15명씩 두 집단으로 나누어 각각 methylphenidate($0.5{\sim}0.6mg/kg)$와 imipramine(25${\sim}100mg$)을 경구투여(經口投與)하고, 투여 1개월후 및 2개월후에 각 1회씩 다시 부모와 교사들에게 같은 평정척도(評定尺度)로 이들의 행동을 평가시키고 아울러 지능검사(知能檢査)를 제외한 모든 신경심리학적검사(神經心理學的檢査)를 시행하였다. 그 결과를 보면 imipramine을 투여받은 아동들은 투여 1개월후 아동행동조사표(兒童行動調査表)(CBCL)의 외상성(外商性)과 과잉행동(過剩行動)${\cdot}$사회적위축요인(社會的萎縮要因)에서 호전을, 그리고 2개월후에는 학교상황질간지(學校狀況質間紙), 코너스씨(氏) 단축형 교사평정척도(短縮形 敎師平定尺度)(CATRS) 및 연속과제수행(連續課題遂行)(CPT)에서 호전을 보였다. 반면 methylphenidate를 투여받은 아동들은 투여 1개월후 부터 부모가 평가하는 코너스씨(氏) 단축형 부모평정척도(短縮形 父母平定尺度)(CAPRS), 아동행동조사표(兒童行動調査表) 및 연속과제수행(連續課題遂行)에서 호전을 보였고, 투여 2개월후에서도 같은 양상의 호전을 보였으며, 또한 아동행동조사표(兒童行動調査表)에서 외향성(外向性)은 물론 소통불능(疏通不能)${\cdot}$사회적위축(社會的萎縮)${\cdot}$과잉행동(過剩行動)${\cdot}$공격성(攻擊性)${\cdot}$비행요인(非行要因)에서도 호전양상을 보였다. 이와같은 결과는 이 두 약물이 모두 주의력(注意力)과 인지기능(認知機能)을 증진시키기는 하였으나, 보다 뚜렷한 변화는 methylphenidate 투여후에 볼 수 있었다. 특히 methylphenidate투여후 연속과제수행(連續課題遂行)에서 민감도(敏感度)와 반응오류수(反應誤謬數)의 호전이 있었으나 반응기준(反應基準)에는 변화가 없었다는 소견, 그리고 단기기억수행(短期記憶遂行)에서의 호전과 '같은 그림 찾기' 검사의 오류수(誤謬數)에서 변화가 없었다는 소견은 methylphenidate가 훈기요인(勳機要因)의 호전에 의한 이차적인 변화에 의한 것이 아니라 주의집중력(注意集中力)에 직접적으로 효과를 나타내는 것으로 해석할 수 있었다. 또한 이같은 소견으로 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애환아(過剩運動障碍患兒)에서의 충동성(衝動性)은 이 장애의 중심증상이 아니거나, 이들 약물투여에 의해 호전되지 않거나, 호전의 측정에 문제가 있을 수도 있겠다. 마지막으로 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애(過剩運動障碍)에서 과잉행동(過剩行動)과 주의력결핍(注意力缺乏)이 서로 다른 신경전달체계(神經傳達體系)를 통해서 나타날 가능성에 대해서도 논의하였다.

Objective: This study aims to recognize the risk of current traffic systems and to investigate a method to decrease risk by doing exercise using an elastic-band and cognitive rehabilitation. Background: The existing traffic system usually focuses on the ordinary citizens, which may not be appropriate to the elderly. It may affect the cognition and walking speed of the elderly. This study tries to examine whether cognition and muscle training is appropriate to improve their vulnerability. Therefore this study will provide human ergonomics - based basic data in relation to the elderly to identify the risk of current signal system and to mitigate the risk. Method: A total of 30 elderly participants were divided into two groups: experimental and control groups. Experimental group (n=15) was trained to strengthen their muscles and to promote cognition, whereas control group (n=15) was not. The training was conducted twice a week for three weeks. To strengthen muscles, a yellow colored elastic-band was used, and a computer program for cognitive rehabilitation was used to develop cognition. In the experimental group, there were significant differences between pre and post exercises However, the control group didn't show any significant difference. The increase in cognition and walking speed was found in the experimental group, whereas there were no differences in the control group. Statistically there was no significant difference between the two groups. Results: The results of this study show that the exercise program using the elastic-band gave a positive effect on gait training thanks to the development of muscle power and balance. Conclusion: This study did not show any statistical difference or significant differences between the two groups, since time was restricted, we believe. Application: The results of the walking speed will help to prevent traffic collision.

Objectives: The aim of this study was to develop the computerized Comprehensive Learning Test-Reading (CLT-R) to evaluate the cognitive processes and achievements related to their basic reading ability and identify dyslexia in children and adolescents in South Korea. We also obtained the normative data and evaluated the reliability and validity of the test. Methods: We developed the CLT-R, including the word attack/nonword decoding, paragraph reading, sound blending, nonword repetition, rapid automatized naming, letter-sound matching, visual attention, orthography awareness, and digit span tests, for the purpose of diagnosing dyslexia. We investigated the reliability and validity of the tests and gathered the normative data from 399 subjects (male 48.9%), aged 5-14 years, from the last grade in kindergarten to middle school, dwelling in Seoul and Gyeonggi Province, South Korea. Results: No statistical differences were observed between the means of the tests and retests of the CAT. The mean of the correlation coefficient of the test-retest scores was 0.85. According to the construct validity test calculated by principal constant analysis using the oblique rotation method, 4 factors explained 70.0% of the cumulative variances. In addition, the normative data were obtained for all of the CLT-R subtests. Conclusion: The computerized CLT-R can be used as a reliable and valid tool to evaluate the reading achievement and reading related cognitive process in Korean children and adolescents in schools, clinics, and research institutes.

Background: Parkinson's disease is movement disorder due to dopaminergic deficiency. It has been noted that cognitive dysfunction also presented on Parkinson's disease patients. But, it is not clear whether such a cognitive dysfunction was a dopaminergic dysfunction or cholinergic dysfunction. Using linear and non-linear analyses, we analysed the effect of cognitive and motor symptom on EEG change. Methods: EEGs were recorded from patients with Parkinson's disease and essential tremor, and normal controls during rest. We calculated the power spectrum, correlation dimension and Lyapunov exponent by using 'Complexity'program. The power spectrum, correlation dimension, and Lyapunov exponent were compared between Parkinson's disease patients and essential tremor patients. Results: Theta power was increased in Parkinson's disease patient group. Correlation dimension was increased in Parkinson's disease patients. Positive correlation was noted between MMSE and correlation dimension, and negative correlation was noted between MMSE and Lyapunov exponent. Lyapunov exponent was decreased in Parkinson's disease patient. Conclusions: We conclude that the state of Parkinson's disease patient is characterized by increased correlation dimension and decreased Lyapunov exponent.

Depression is a major mood disorder. Abnormal expression of glial glutamate transporter-1 (GLT-1) is associated with depression. Schisantherin B (STB) is one bioactive of lignans isolated from Schisandra chinensis (Turcz.) Baill which has been commonly used as a traditional herbal medicine for thousands of years. This paper was designed to investigate the effects of STB on depressive mice induced by forced swimming test (FST). Additionally, we also assessed the impairment of FST on cognitive function in mice with different ages. FST and open field test (OFT) were used for assessing depressive symptoms, and Y-maze was used for evaluating cognition processes. Our study showed that STB acting as an antidepressant, which increased GLT-1 levels by promoting PI3K/AKT/mTOR pathway. Although the damage is reversible, short-term learning and memory impairment caused by FST test is more serious in the aged mice, and STB also exerts cognition improvement ability in the meanwhile. Our findings suggested that STB might be a promising therapeutic agent of depression by regulating the GLT-1 restoration as well as activating PI3K/AKT/mTOR pathway.

Objectives: The purpose of this overview was to summarize the evidence regarding the effectiveness of Cognitive Behavioral Therapy (CBT) for sleep disorders through systematic reviews (SRs) and meta-analyses (MAs). Methods: An overview of systematic review was conducted according to the study protocol (reviewregistry1320). A comprehensive literature search was performed using three databases (Pubmed, Cochrane Central Register of Controlled Trials, and Web of Science) and three Korean databases (KoreaMed, KMbase, and ScienceON). Final studies were selected by three authors according to inclusion and exclusion criteria, and data needed for analysis were extracted by a pre-planned extraction framework. Methodological quality of systematic review was assessed using the 'Assessment of multiple systematic reviews 2 (AMSTAR2)'. Results: Fourteen SRs and MAs were included, of which eleven SRs were performed MAs. Twelve studies studied insomnia among sleep disorders, and the rest are nightmares and sleep disturbances with PTSD. Ten studies reported the effect of CBT on sleep disorders measured by insomnia severity index (ISI) and sleep onset latency (SOL), and all reported a significant improvement effect. Eight studies reported the effect of CBT on sleep disorders measured by wake time after sleep onset (WASO), and seven studies reported a significant improvement effect. The methodological quality of the studies evaluated with AMSTAR 2 was mainly low or very low because of omission of protocol registration and excluded study list. Conclusions: Practical guidelines and studies show that CBT is effective for sleep disorders, but access to CBT needs to be improved.

Objectives : It has been shown that early intervention is crucial for favorable outcome in patients with schizophrenia. However, development of biomarkers for predicting prognosis of psychotic disorder still requires more research. In this study, we aimed to investigate whether baseline mismatch negativity (MMN) predict prognosis in patients with first episode psychosis (FEP). Methods : Twenty-four patients with FEP and matched healthy controls (HCs) were examined with MMN at baseline, and their clinical status were re-assessed after 1 year. Repeated-measures analysis of variance was performed to compare baseline MMN between the two groups. Multiple regression analysis was used to identify factors predicting prognosis in FEP patients during the follow-up period. Results : MMN amplitudes at baseline were significantly reduced in patients with FEP compared to healthy controls. In the multiple regression analysis, baseline MMN amplitude significantly predicted later improvement of performances on digit span and delayed recall of California Verbal Learning Test. However, baseline MMN did not predicted improvement of clinical symptoms. Conclusion : These results indicate that MMN may be a possible predictor of improvement in cognitive functioning in patients with FEP. Future study with larger sample and longer follow-up period would be needed to confirm the findings of the current study.

연구목적 : Alexithymia(감정표현불능증)는 내면적 감정을 올바로 인식하거나 언어적으로 표현하기 어려운 상태를 뜻하는 용어이다. 최근에는 말로 표현하는데 장애가 있는 것만이 아니라 인지과정에서의 결함도 강조하고 있다. 그리고 감정은 신체증상과 전반적인 건강상태에 영향을 준다는 점에서 정신신체연구에 매우 중심적인 역할을 하고 있다. 이에 본 연구는 신체형 장애 환자와 정신신체장애의 하나로 알려져 있는 당뇨병 환자를 대상으로 alexithymia의 척도를 비교하고 이 환자들에서의 정신병리와 성격특성을 알아 보고자하였다. 방법 : 본 연구는 만 18세 이상의 신체형장애 환자 20명, 당뇨병 환자 20명 그리고 정상 대조군 20명을 대상으로 세 군의 alexithymia의 정도, 정신병리 및 성격특성을 알아보기 위하여 각각 Toronto Alexithymia Scale(TAS), 한국판 Symptoms Check List 9G-R(SCL-90-R) 및 Sixteen Personality Factor Questionnaire(16-PF)를 이용하여 세 군간의 차이를 분석하고 TAS와 SCL-90-R 및 TAS와 16-PF와의 상관관계를 분석하였다. 결과 : 1) TAS에 따른 세 군간의 비교에서는 신체형장애 환자군이 당뇨병 환자군과 정상 대조군보다 유의하게 높은 수치를 나타냈다. 2) SCV90-R에 의한 비교에서는 신체화증상과 불안증상 척도에서 신체형장애 환자군이 당뇨병 환자군과 정상 대조군보다 유의하게 높게 나타났다. 강박증상, 우울증상, 공포증상 및 정신증상 척도에서는 선체형장애 환자군이 정상 대조군보다 유의하게 높게 나타났다. 전체지표 중 전체심도지수는 신체형장애 환자군과 당뇨병 환자군이 정상 대조군보다 높았고, 표출증상심도지수는 신체형장애 환자군과 당뇨병 환자군이 정상 대조군보다 높았으며 표출증상합계에서는 신체형장애 환자군이 정상 대조군보다 유의하게 높은 결과를 보였다. 3) 16-PF에 의한 비교에서는 지능요인에서만 정상 대조군이 신체형장애 환자군보다 높게 나타났고 다른 요인에서는 차이가 없었다. 4) TAS와 SCL-90-R과의 상관관계분석에서는 신체형장애 환자군에서 표출증상심도지수를 제외한 모든 척도에서 정적 상관관계를 보였다. 그러나 다른 두 군에서는 유의한 상관관계를 보이지 않았다. 5) TAS와 16-PF와의 상관관계분석에서는 모든 대상군에서 유의한 상관관계를 보이지 않았다. 결론 : 신체형장애 환자군이 당뇨병 환자군이나 정상 대조군에 비하여 높은 alexithymia 척도와 많은 정신병리를 보였다. 그리고 신체형 환자군에서의 높은 alexithymia 척도는 정신병리와 유의한 정적 상관관계를 보이고 있었다. 당뇨병환자들은 정상 대조군과 유의한 차이를 보이지 않았다. 그러므로 신체형장애 환자들에게는 감정을 표현하고 그들의 정신병리를 완화하거나 해소할 수 있는 치료적 접근이 도움이 되겠고, 당뇨병환자들에게는 우선적으로 신체질환의 상태를 호전시킬 수 있는 치료가 더욱 필요로 하겠다.
