The clinical efficacy of serotonin reuptake inhibitors such as clomipramine in the treatment of obsessive compulsive disorder(OCD) has fueled interest in the neurobiological basis of this illness. OCD is responsive exclucively to potent serotonin reuptake inhibitors clomipramine, fluoxetine, fluvoxamine, sertraline, and paroxetine and this point forms the important evidence supporting a cental role for serotonin in the pathogenesis of the disorder. Other serotonergic medications such as lithium, buspirone, trazodone, or fenfluramine may be useful as adjuvant treatments in treatmentrefractory OCD and adjuvant antipsychotics are useful in tic disorders, personality disorders, and psychotic disorders. This paper reviews results of treatment studies, investigations of biological markers, and neuroendocrine challenges and implications for the role of serotonin in pathophysiology and treatment of OCD.

In the International Classification of Sleep Disorders(ICSD), REM sleep behavior disorder(RBD) and nightmares are classified as 'parasomnias usually associated with REM sleep'. RBD can be defined as the intermittent absence of REM sleep EMG atonia and the appearance of the elaborate motor activity associated with dream mentation. Bilateral pontine tegmental lesions in cats induce RBD-like behavior, but in human cases, more than 60% are idiopathic. Polysomnograpy shows characteristic findings in REM sleep and treatment with clonazepam is highly effective. With nightmares as long, frightening dream decreasing with age, their persistence or apperance in adults is related with certain drugs, trauma, personality and psychotic episode. Psychotherapy, behavior techniques or medication is used for treatment, but all of nightmares do not require treatment.

목적 : 소아 청소년 정신과 환자에서 비전형 항정신병약물인 risperidone에 대한 효과 및 안전성에 대한 자료를 얻고자 하였다. 방법 : 2001년 1월에서 2002년 6월까지 서울대병원 소아 청소년 정신과 병동에 입원한 환자 중 risperidone이 사용되었던 5.4세에서 17.3세 사이의 환자 31명(남 18, 여 : 13)을 대상으로 후향적인 진료기록지 검토를 시행하였다. 결과 : Risperidone이 사용된 주된 정신과 진단은 정신분열병 및 기타 정신증, 정신병적 증상이 동반된 I형 양극성 장애, 뚜렛장애, 자폐스펙트럼 질환, 혼합형 표현성 및 수용성 언어장애, 주의력결핍 과잉행동장애 및 품행장애, 강박장애 등이었으며 이 중 12명에서 정신지체가 동반되었다. Risperidone사용의 주된 목표 증상은 정신병적 증상(n=13, $41.9\%$), 공격성, 충동성, 과잉행동, 상동증 등과 같은 행동 증상(n=10, $32.3\%$), 만성적이고 심한 틱 증상 (n=8, $25.8\%$)이었다. Risperidone의 효과는 risperidone의 목표 증상에 대한 CGI(Clinical Global Improvement)로 평가되었는데 $67.7\%$에서 중등도 이상의 호전을 보였고 평균 7.5개월 동안 치료효과가 유지되었다. Risperidone의 평균 하루 사용량은 $0.05{\pm}0.1mg/kg$이었으며, 정신병적증상군이 0.07mg/kg로 다른 두 증상군(0.04mg/kg)에 비해 의미 있게 높았다. 부작용으로는 체중증가(n=23)가 가장 흔하였으며 그 외 추체외로계 증상(n=15), 자율신경계증상(n=6), 진정작용(n=5), 고프로락틴혈증(n=2) 등 다양한 부작용이 보고되었다. 그러나 부작용으로 인해 약물을 변경한 경우는 없었으며 외래 마지막 방문 시 $90\%$에서 risperidone을 유지하고 있어 약물내약성은 비교적 우수한 것으로 평가되었다. 결론 : 비전형 항정신병 약물인 risperidone은 정신병적 증상, 공격성, 충동성, 과잉행동, 상동행동을 포함하는 행동증상, 만성적이고 심각한 틱증상 등 다양한 소아 청소년 정신병리의 치료에 비교적 안전하고 효과적인 약물이 될 수 있을 것으로 평가된다. 향후 risepridone의 효과 및 안전성에 대한 보다 장기적이고 체계적인 연구가 필요할 것이다.

To examine the double-faced thymoleptic(antidepressant and antimanic) effects of risperidone in mood disorders, this article reviews the psychotropic-induced mania, thymoleptic effects of antipsychotics, therapeutic effects of risperidone and risperidone(RIS)-induced mania(RIM) in mood disorders, risk factors of RIM, possible neurochemical mechanism of these thymoleptic effects, pathophysiological and clinical significance of thymoleptic effects, and suggestive clinical guideline of RIS in mood disorders. RIS appeared effective for bipolar disorder at a lower dose than that recommended for schizophrenia, especially in the cases of maintenance of mood stabilizers, and gradual titration from low doses. Manic induction/exacerbation can occur by chance during RIS treatment in mood disorders, schizoaffective disorders, and schizophrenias. The possible risk factors for RIM are refractory mood disorder, especially in bipolar I disorder with poor initial response ; refractory schizoaffective disorders, especially in bipolar type with poor initial response ; refractory chronic schizophrenias, especially with initial responses ; psychotic features ; higher initial doses ; rapid titration ; combined therapy with antidepressants in refractory depression ; and RIS monotherapy in mania/hypomania. RIS is a drug that preferentially block 5-HT2 receptors. The effects of low dose are due mainly to the blockade of 5-HT2 receptors. There are more gradual increase in D2 blockade with increasing dose and this D2 blocking properties become apparent at higher doses. This may be related to a modulation of dopaminergic transmission by 5-HT2 antagonism at lower doses with the direct action of RIS on DA receptors coming into play at higher dose. The serotonergic antagonistic effect may be important for its effects on depressive symptoms. This, together with adequate blo-ckade of D2 receptors, may not necessarily lead to destabilization of mood disorder, but rather to more therapeutic effects. Therefore, this dose-receptor affinity relationship with both antidepressant and antimanic effects according to treatment duration can explain a continuum of antidepressant effect, antimanic effect, behavioral stimulation, and manic/hypomanic induction/exacerbation. It was the recognition of a useful psychiatric side effects by a thoughtful observer with fertile minds that led to their ultimate utilization as psychotropic drugs, i.e., phenothiazine, MAOI, TCA, and lithium. And, in vivo pharmacological challenge by novel psychotropics, as a neurochemical probe, with more specific actions is a useful tool to select pharmacologically homogeneous subgroup of the same phenotypical(clinical) condition, to further study the unknown underlying pathogenesis of various mental illnesses. Finally, RIS may be a useful alternative or adjunctive drug for patients with mood disorders without psychotic features or refractory to treatment with standard antipsychotic drugs. The more conservative doses(tirated slowly from 1-3 mg/d) of RIS, and maintenance of mood stabilizer in the cases with risk factors of RIM are recommended in mood disorder.

Reactive disorder is a group of diagnosis with a definitely known etiology and whose etiological factor is essential to the diagnosis. In DSM system, such reactive disorders are listed as adjustment disorder, acute stress disorder, brief psychotic disorder with marked stressor and posttraumatic stress disorder (PTSD). However, a growing number of individuals is suffering from a prolonged feeling of embitterment after exceptional negative life events and this condition could be diagnosed neither PTSD nor adjustment disorder nor depressive disorder in the context of DSM-IV diagnostic system. This clinical condition can be described as 'posttraumatic embitterment disorder' (PTED). PTED is a reactive disorder triggered by exceptional, though normal negative life events such as conflict in the workplace, unemployment, death of a relative, divorce, severe illness, or experience of loss or separation. The common feature of such events is that they are experienced as unjust, as a personal insult, accompanied by psychological violation of basic beliefs and values. The central psychopathological response pattern in PTED is a prolonged feeling of embitterment. In particular, the core emotion of embitterment can lead to the rejection of treatment. Therefore, "wisdom therapy" as a new treatment approach specifically designed for PTED has been developed. It is assumed that many patients suffering from PTED are often misunderstood and misdiagnosed. This review would help to introduce PTED into the clinical field in psychiatry.

Prader-Willi syndrome (PWS) is a quite rare multi-systemic genetic disorder strongly associated with psychiatric illness in adults, especially psychosis. This report presents a 16-year-old female with PWS and symptoms of brief psychotic disorder with a complete resolution of symptoms under aripiprazole medication. However, an exacerbation occurred after aripiprazole reduction. Apart from a weight gain of about 2 kg over the course of two years, no adverse effects could be found. This first report on the use of aripiprazole in a subject with PWS and psychosis suggests that aripiprazole might be a promising treatment approach in this distinct group of patients.

Objectives Despite the growing research interest in the role of immunological markers in schizophrenia, a few studies, with conflicting results, have focused on the association between high sensitivity C-reactive protein (hs-CRP) levels and clinical characteristics in schizophrenia. The aim of the present study was to examine the association of serum hs-CRP with psychopathology in schizophrenia. Methods Fifty-five inpatients with schizophrenia or schizoaffective disorder were enrolled. Serum levels of hs-CRP were measured, and each patient was assessed with the Korean version of the Positive and Negative Syndrome Scale (PANSS). Results In correlation analysis of hs-CRP with PANSS subscales, positive subscale score has significant positive correlation (r = 0.271, p = 0.046). In independent t-test analysis, subjects with hs-CRP > 0.3 mg/dL (elevated CRP group, n = 43) had significantly higher PANSS positive subscale score (t = -3.273, df = 24.107, p = 0.003) than those with hs-CRP ${\leq}$ 0.3 mg/dL (normal CRP group, n = 12). Conclusions Elevated serum levels of high sensitivity C-reactive protein in schizophrenia are associated with the severity of psychotic symptoms.

Objectives:This study was to compare verbal memory ability among patients with schizophrenia, bipolar manic patients and unipolar depressive patients, and to understand their charicteristics of memory process. Methods:All subjects were hospitalized patients and had been interviewed by using the Structured Clinical Interview for DSM-IV(SCID). Schizophrenic patients(N=40), bipolar manic patients(N=17), and unipolar depressive patients(N=20) were assessed with K-AVLT for verbal memory and with K-WAIS for verbal IQ. Three groups were compared regarding total immediate recall, delayed recall, delayed recognition, learning curve, memory retention, and retrieval efficiency under controlled verbal IQ. Multiple regression analysis was performed to find which clinical factors have an influence on verbal memory ability. Results:In MANCOVA, differences of verbal memory test scores among the groups were statistically significant(F=1.800, p<.05). In post hoc analysis, Patients with schizophrenia and bipolar mania showed poorer performance in immediate recall, delayed recall, delayed recognition, retrieval efficiency than unipolar depres- sive patients. And schizophrenics performed poorly in delayed recall, delayed recognition, retrieval efficiency than nonpsychotic affective disorder group, but no difference in total immediate recall, delayed recall, delayed recognition, retrieval efficiency between the schizophrenic group and the psychotic affective group. Conclusions:These results partially confirm previous reports of verbal memory ability among major psychiatric disorders. Our results showed that psychotic symptoms were related with verbal memory, and longer duration of illness was related with poorer performance in schizophrenia and unipolar depression.
