Objectives : Delirium of hospitalized patients is common and it is significantly associated with increased mortality rate. Misdiagnosis rates of delirium are reported in a range of 36.7 to 63% in clinical setting. We aimed to identify the clinical features and symptomatic characteristics associated with misdiagnosis of delirium. Methods : Subjects were 256 inpatients who were referred for psychiatric consultation and diagnosed with delirium by a psychiatrist at a university hospital between January 1 and June 30, 2012. Clinical data were obtained with retrospective chart review. Patients were divided into misdiagnosed group and correct diagnosed group, after reviewing the reason which were described in the consultation request form. Results : Sixty nine(27%) subjects of the 256 patients were referred for other reasons(mood, substance, anxiety, dementia etc.) than "delirium/confusion" by clinician(misdiagnosed group). In misdiagnosed group, use of antipsychotics was more common. There were no differences between the two groups in age, gender, and department of referring clinician. Fluctuation score of DRS-R-98 was higher in the correct diagnosed group. Conclusions : In this study, the risk of misdiagnosis was higher when the patients have taken antipsychotics or less symptom fluctuation. Careful clinical attention is needed for diagnosis for delirium in these patients.

Objective: This study aimed to investigate the pattern of psychiatric consultation-liaison in a new general hospital over a 5-year period. Method: Retrospective chart review was conducted for psychiatric consultations performed from May 2004 to December 2008 in a new general hospital in Hwasun, Korea. Results: A total of 1,852 patients who were referred to the Department of Psychiatry for consultation were included in the analysis. The main reasons for psychiatric consultation were changes in mental status(20.5%), depression(16.8%), insomnia(12.8%), and anxiety(7.9%). Psychiatric consultations were conducted with diagnoses of delirium(39.7%), depressive disorder(28.2%), adjustment disorder(7.9%), and anxiety disorder(4.1%). Patients with delirium were significantly older than were those with other psychiatric diagnoses(p<0.001). Delirium was more common in male patients than in female patients(47.1% vs. 29.9%, respectively), and depression was more common in female patients than in male patients(48.3% vs. 33.9%, respectively)(p<0.001). Delirium was more common in patients who underwent surgical operation than those who did not(p=0.010). Conclusion: Delirium was the most common diagnosis for psychiatric consultation followed by depression in a university hospital. Delirium was more prevalent in men than in women, while depression was more common in women.

실어증 감별진단검사법은 실어증환자들의 진단, 치료계획의 설정, 치료 효과 및 예후의 판정 등을 위하여 사용된다. 그러나 아직 우리나라에는 우리에게 알맞은 실어증 감별진단 검사법이 개발되지 않았으므로 본 연구에서는 정신문화 및 언어구조면에서 우리나라와 유사성이 가장 높다고 생각되는 일본에서 널리 사용되고 있는 실어증 감별진단검사법(노인총합 연구소판)을 우리나라의 정신문화 및 언어상의 특성을 고려하여 번역 보완환 다음 한국어판 실어증 감별진단검사법을 시안(I)을 실어증 환자군과 정상 대조군에 적용하여 그 가치를 평가하고자 하였다.

This study assessed psychiatrically referred 5-to 13-year-old children who presented inattention or hyperactivity as chief complaints. Demographic characteristics, primary diagnosis, and comorbid psychiatric conditions of them were identified, and they were assessed using questionnaires and neuropsychological tests. Primary diagnoses included ADHD, anxiety disorder, mental retardation, depression, oppositional defiant disorder, developmental language disorder and others. functional enuresis, conduct disorder, and developmental language disorder were among the secondarily diagnosed disorders. In patients diagnosed as ADHD, overall comorbidity rate was 55.3%. The disorders that frequently co-occured with ADHD were specific developmental disorder, conduct disorder, oppositional defiant disorder, anxiety disorder and other. ADHD groups with or without comorbidity differed in performance IQ and CPT scores. ADHD group differed from externalizing disorders group in the information subscore of IQ, MFFT, and CPT scores, and differed in teachers rating scales, the uncommunication factor of CBCL, and CPT card error compared with internalizing disorders group. The authors concluded that inattentive or hyperactive children should be assessed using various instruments to differentiate other disorders and to identify possible presence of comorbid conditions.

Until recently, the etiology of schizophrenia was generally attributed to abnormalities in dopaminergic neurotransmission. Specifically, an excess of dopaminergic activity in the mesolimbic system has been postulated to produce the positive symptoms, while decreased dopaminergic activity in the mesocortical system has been suggested to cause negative symptoms. Accordingly, we performed an association study of schizophrenia with TH gene. Three hundred and seventy four biologically unrelated schizophrenic patients meeting DSM-III-R criteria from Kangnam St. Mary's Hospital affiliated with Catholic university of Korea were recruited for our study. The 393 healthy controls were volunteers for DNA library of Kangnam St. Mary's Hospital without personal or family history of psychiatric and neurologic illness. DNA was extracted from peripheral mononuclear cells and polymorphic region was amplified by polymerase chain reaction. TH intron 1 VNTR polymorphism was typed by silver staining. The allele distributions of TH gene were not different between schizophrenics and controls. However, the frequency of allele A was significantly higher in positive group than that of negative group of schizophrenics. These findings suggest that poitive schizophrenia may be associated with allele A of TH gene.

A psychogenic seizure is a disorder which is occasionally met by neurologists and psychiatrists. The most important thing that clinicians should do is differential diagnosis with true epileptic seizures. Especially psychiatrists are expected to be able to diagnose psychogenic seizures through a thorough history taking and an observation of clinical features to some degree before the confirmatory diagnoses. We experienced a case of 11-year-old girl with psychogenic seizure which was characterized by obvious psychological and environmental stress, clinical features, and good outcome by prompt a loboratoy examination and psychiatric intervention. To diagnose and treat childhood psychogenic seizures, we suggest that it is very important to examine the familial background and take a thorough history, and perform psychoeducational intervention in addition to electroencephalogram.

This review is a clinical and research update of recent literature related to childhood onset schizophrenia (with an onset of psychosis by age 12). Childhood onset schizophrenia(COS) is a rare disorder, but that may represent a more homogeneous patient population in which to search for risk or etiologic factors of schizophrenia. These overview data show that COS shares the same clinical and neurobiological features as later onset forms of the disorder. Compared with later onset schizophrenia, however, this subgroup of patients appear to have more severe premorbid neurodevelopmental abnormalities, more cytogenic abnormalies, poor outcome, and potentially greater family histories of schizophrenia and associated spectrum disorders. Future studies of this subgroup may provide important clues as to the genetic basis for schizophrenia and how gene products influence certain feature of the disease, such as age of onset and mode of inheritance.

해마다 정신 질환의 발병률은 높아지지만, 이를 위한 진단과 치료의 한계는 현재까지도 해결되지 않고 있다. 디지털 치료제(DTx)는 이러한 한계를 극복할 수 있는 새로운 해결법으로 화두되고 있다. 본 연구는 객관적인 ADHD 진단을 위한 Hippo T&C의 디지털 치료 솔루션인 AttnKare-D를 제안한다. AttnKare-D는 정신 질환의 진단 및 통계 편람(DSM-5)에 따라 통제된 환경에서 데이터를 정량화함으로써 진단을 객관화한다. 또한, ADHD의 세부적 증상에 대한 상세한 보고서를 만듦으로써, 넓은 분류보다는 특정한 증상들에 집중하여 치료를 개인화한다. 적절한 샘플 사이즈에 낮은 오류율을 보이므로 임상 환경에서 AttnKare-D는 긍정적인 가능성을 보여준다.

현대인에게 있어서 피할 수 없는 스트레스. 이 스트레스로 인해 현대인들은 신체적인 건강뿐만 아니라 우울증 등의 정신건강까지 위협을 받고 있으나 정신과라는 좋지 않은 인식으로 인해 정신건강은 제대로 치료되지 못하고 있는 실정이다. 하지만 양극성 장애(조울증)를 앓고 있다면 이야기가 좀 달라져야 한다.
