목 적：중추신경계 질환의 병발 여부에 따라 렘수면 행동 장애 환자들을 두 군으로 나눈 후, 인구학적 특성, 임상양상, 수면 변인들을 비교하여 차이점과 특성을 관찰하고자 하였다. 방법：서울대학교병원에서 야간수면다원검사를 통해 렘수면 행동장애로 확진받은 81명을 대상으로 하였다. 의무기록과 수면다원검사 소견을 후향적으로 조사하였고 필요한 경우 전화문진을 통해 자료를 보완하였다. 중추신경계 질환력과 뇌 자기공명검사 소견을 근거로 전체 대상을 중추신경계 질환을 동반한 병발성 렘수면 행동장애군과 그렇지 않은 특발성 렘수면 행동장애군으로 이분하였다. 그 후 두 군 사이의 인구학적 특성, 임상양상, 수면 변인을 비교분석하였다. 결 과：전체 대상군 81명 중 남자는 64명, 여자는 17명이었다. 그리고 전체 대상중에 21명(25.9%)에서 중추신경계 질환이 동반되어 병발성 렘수면 행동장애군으로, 나머지 60명(74.1%)에서 그렇지 않아 특발성 렘수면 행동장애군으로 분류하였다. 동반된 중추신경계 질환은 파킨슨병(11명), 올리브뇌교소뇌위축(olivopontocerebellar atrophy)(3명), 다발신경계위축증(multiple system atrophy)(2명), 파킨슨병을 동반하지 않은 치매(2명), 뇌경색(1명), 뇌교부종(1명), 뇌종양(1명)이었다. 전체 대상에서 수면장애가 병발된 경우는 74.1%로서 주기성 사지운동증과 폐쇄성무호흡증이었다. 주기성 사지운동증(사지운동 지수>5)과 폐쇄성 수면무호흡증(호흡장애지수>5)의 유병율이 병발성 렘수면 행동장애군에서 유의하게 높았다(각각 p<0.001, p=0.0042, Fisher 검증). 심한 정도를 나타내는 주기성 사지운동지수와 호흡장애지수도 병발성 렘수면 행동장애군에서 유의하게 높았다(각각 p<0.001, p=0.017, 독립 t-test). 수면변인 중 서파수면분율과 수면효율은 병발성 렘수면 행동장애군에서 유의하게 낮았다(각각 p<0.001, p=0.017, 독립 t-test). 고 찰：렘수면 행동장애 환자의 25%에서 중추신경계 질환이 동반되어 있음을 확인하였다. 중추신경계 질환이 동반된 렘수면 행동장애에서는 주기성 사지운동증과 폐쇄성 수면 무호흡증 같은 다른 수면장애가 더 흔하게 병발하였고 그 정도 역시 더 심하게 나타났다. 수면구조에서도 특발성 렘수면 행동장애에 비해 서파수면과 수면효율이 모두 더 감소하는 소견을 보였다.

The use of alcohol is associated with the development and worsening of sleep disorder. Alcohol is generally known to have a sedative effect, but it has an arousal or sedative effect depending on the timing and drinking dose and directly affects REM sleep physiology. Alcohol acts on the central nervous system (CNS) to interfere with the sleep-wake cycle and to affect sleep-related hormone secretion. In addition, the ingestion of alcohol pre-sleep is associated with deterioration and development of sleep related breathing disorders (SBD). The increase in resistance of the upper respiratory tract and the decrease in sensitivity of the CNS respiratory center and the respiratory muscles are major mechanisms of alcohol-induced SBD, and result in snoring or apnea in healthy men or aggravating apnea in patients with OSA. Sleep-related restless leg syndrome and circadian rhythm disorders are common in alcohol use disorder patients. This review provides an assessment of scientific studies that investigated on the impact of alcohol ingestion on nocturnal sleep physiology and sleep disorders.

Mood disorder is a medical illness resulting from the disorder of CNS neurotransmission and its principal therapeutic tool is pharmacotherapy. Psychotherapeutic drugs for mood disorder have some clinical limitations which are due to no or partial response, decreased compliance for drug by the side effects, and delayed therapeutic effects. So, general hope of all clinicians that mood diorder will respond to a single psychotherapeutic agent may be the exception rather than the rule. Recently, combined drug treatments have become increasingly popular to overcome the clinical limitations of individual agent in mood disorder. Combined treatments are usually used for augmenting or initiating rapidly the effect of drug, and for treating different target symptoms or drug side effects. When combined treatments being tried, knowledge of the action mechanism, pharmacokinetics, and pharmacodynamics is crucial to cope with the possible adverse reactions of drugs.

기능성 위장관 장애(functional gastrointestinal disorder, FGID)의 생물학적 병태생리는 아직 명확하지 않은 실정이나 최근에 뇌-장관 축(brain-gut axis, BGA) 모델이 각광받고 있다. BGA 모델은 중추신경계(CNS)와 장관신경계(ENS)가 신경계, 신경내분비계, 신경면역계 등으로 밀접하게 연계되어 양방향성으로 항상성을 유지한다는 이론이다. 또한 BGA는 FGID에 대한 항우울제 효과의 이론적 근거를 제공한다. 저자들은 세로토닌 노르에프네프린 재흡수 차단제인 duloxetine이 목 이물감, 우울감을 보이는 환자와 상부 위장관 팽만감, 건강염려증적 불안을 보이는 환자에서 위장관 증상 및 정신의학적 증상에 효과적이었음을 경험하였다. 이에 두 증례보고를 통하여 BGA에 대해서 간략히 검토하고 duloxetine의 효과를 BGA의 측면에서 고찰하였다. 이 두 증례에서 duloxetine의 장관에서 뇌로의 영향(bottom-up regulation)으로는 세로토닌 수용체, 노르에피네프린 수용체 그리고 부신피질자극호르몬방출인자(CRF) 길항효과를 통해서 내장과민성(visceral hypersensitivity) 및 정신의학적 증상을 호전시키고, 뇌에서 장관으로의 영향(top-down regulation)으로는 우울과 불안을 호전시킴으로 위장관 증상에 영향을 미친 것으로 추정해 볼 수 있다.

A prevalence study was carried out on 847 CMD patients who had visited the Department of Oral Medicine in Pusan National University from 1990 to 1993. To obtain the same type of information, all subjects were interviewed and examined clinically using a standardized examination form, The ratio of women to men was about 3:1 and all subjects were divided into acute and chronic groups on the basis of 6 months of duration. Diagnostic groups consisted of muscle disorder, joint disorder and muscle-joint disorder. As related to gender, duration and diagnosis subjective and objective symptoms in CMD were studied. The obtained results were as follows : 1. Muscle-joint disorder had the highest percent, followed by muscle disorder and joint disorder. 2. The most common reasons for CMD treatment were pain, joint noise and limited opening, while headache and neckache were relatively often reported as associated symptoms and dizziness, ringing in the ears also reported as secondary CNS excitatory effects. 3. Pain was more ofter seen in women, acute group and muscle-related disorder groups (p<0.05, p<0.01). Noise was significantly frequent in chronic group and joint-related groups (p<0.01). 4. Analysis of contributing factors presented that macrotrauma was found frequently in men (p<0.05), and that muscle-related groups were more related to stress than joint disorder grop (p<0.05). 5. Hard end feel was seen significantly often in joint-related disorder group (p<0.05). On the other hand, soft end feel was frequent in muscle disorder. 6. Reciprocal clicks and crepitation increased with chronicity. Subjects with joint-related disorder groups significantly often reported all kinds of noises (p<0.01). 7. Tender muscles and joints were more often reported in women and chronic group. Whereas muscle-related disorder groups revealed significantly more tender muscles (p<0.01). joint-related disorder groups presented significantly more tender joints (p<0.01).

Autonomic dysfunction occurs frequently in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). Patients with either condition may present with autonomic symptoms such as bladder, sexual, cardiovascular, thermoregulatory, and gastrointestinal dysfunction, and fatigue, but autonomic symptoms that affect quality of life are underrecognized in clinical practice. The immunopathogenesis of MS has been considered to be associated with autonomic dysfunction. Applying appropriate treatment strategies for autonomic dysfunction is important to improve the quality of life of patients. Here we review autonomic dysfunction and how this is managed in patients with MS and NMOSD.

Inflammatory or immune-mediated demyelinating central nervous system (CNS) syndromes include a broad spectrum of clinical phenotype and different overlapping diseases. Antibodies against myelin oligodendrocyte glycoprotein (MOG-Ab) have been found in some cases of these demyelinating diseases, particularly in children. MOG-Ab is associated with a wider clinical phenotype not limited to neuromyelitis optica spectrum disorder, with most patients presenting with optic neuritis, acute disseminated encephalomyelitis (ADEM) or ADEM-like encephalitis with brain demyelinating lesions, and/or myelitis. Using specific cell-based assays, MOG-Ab is becoming a potential biomarker of inflammatory demyelinating disorders of the CNS. A humoral immune reaction against MOG was recently found in monophasic diseases and recurrent/multiphasic clinical progression, particularly in pediatric patients. This review summarizes the data regarding MOG-Ab as an impending biological marker for discriminating between these diverse demyelinating CNS diseases and discusses recent developments, clinical applications, and findings regarding the immunopathogenesis of MOG-Ab-associated disorders.

Sweet's syndrome also known as acute neutrophilic dermatosis is a multisystem inflammatory disorder characterized by fever, malaise, leukocytosis, and skin lesions. Sweet's syndrome affects multiple organs though only rarely does it affect the central nervous system (CNS) when it does it is called Neuro-Sweet disease (NSD). We report on a case study of a biopsy-proven NSD in a 50 year old man. Serial magnetic resonance imaging (MRI) showed repeated CNS involvement of Sweet's syndrome after a respiratory tract infection preceded it. On the MRI, T2 hyperintense lesions occurred at multiple sites and disappeared after steroid therapy.

Much of the recent increase in research on nicotinic ligands has been motivated by a growing body of evidence that nicotinic cholinergic pharmacology plays a role in disorder associated with deficits of cognitive function in humans. The importance of developing novel nicotinic ligands as potential therapeutics is emphasized by studies with nicotine itself that have demonstrated many useful CNS and cognitive effects in various disorders such as dementia.
