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.

렘수면 행동장애는 렘수면에서 과도한 근전도 활동과 관련된 불쾌한 꿈과 격렬한 행동이 특징인 사건수면이다. 이는 특발성으로 나타날 수 있고, 다른 신경학적 또는 의학적 상태에 이차적으로 나타날 수 있는 등 여러 이질적인 기저 질환이 있을 수 있다. 특발성으로 나타나는 렘수면 행동장애는 대부분 시누클레인 병증으로 인한 신경퇴행성 질환이 나타날 가능성을 의미하므로, 정확한 진단이 예후를 예측하는데 중요하다. 렘수면 행동장애의 진단을 위해서는 수면다원검사에서 나타나는 무긴장증이 없는 렘수면이 필수적이다. 노인 환자에서 수면 중 꿈을 꾸면서 행동을 보이는 질환으로는 폐쇄성 수면 무호흡증, 외상 관련 수면 장애, 수면 중 격렬한 주기적인 다리 운동 등이 알려져 있다. 렘수면 행동장애를 모방할 수 있는 다른 수면장애가 동반되어 나타날 수 있음을 고려하여 신중한 병력 청취와 수면다원검사 등을 이용하여 수면장애의 감별 진단 및 치료가 중요하겠다.

The authors report a case of REM sleep behavior disorder which occurred in a 69-year-old business man. He began experiencing episodic "acting out" behavior of his dream at the age of 66. The episodes tended to be associated with dream contents, mainly being chased or threatened. Before that, his sleep was relatively quiet despite occasional nightmares, midsleep arousal, and shallowness. Injuries resulted from leaping out of bed, jumping onto furnitures, and grabbing and biting the spouse's arm. Most recent dream-incurred laceration of chin required 5 sutures. Medical and psychiatric history revealed no significant findings except that he had been overanxious all his life within himself with others' reputation of himself as pleasant and easy-going. A nocturnal polysomnogram showed repeatedly intermittent increase of chin and/or leg muscle tones during otherwise characteristic REM sleep period. The overnight video recording revealed head lifting and limb movements during REM sleep periods. Brain MRI and EEG were normal. Job-related stress was presumed to be an etiological possibility. Clonazepam 0.25-0.5mg nightly almost completely relieved the symptoms.

목 적: 렘수면 행동장애는 기존 역학 연구에서 큰 관심을 받지 못했다. 본 연구는 유력 렘수면 행동장애의 유병률과 임상 양상에 대해 살펴보고자 하였다. 방 법: 오산시에 거주중인 60세 이상 노인 14,050명 중 1,588명이 임의추출을 통해 표본 집단으로 선정되었고 이들을 대상으로 렘수면 행동장애 선별 설문지로 선별검사를 시행했다. 선별 설문지 점수가 5 이상인 집단은 수면의학 전문가가 직접 개별 면담평가를 시행했다. 결 과: 14,050명의 모집단 중 886명이 1차 선별평가를 마쳤다. 선별검사 설문지 점수가 5 이상인 145명 중 123명이 2차 진단평가를 받았다. 이중 11명이 유력 렘수면 행동장애로 진단되었고 유병률은 1.5%(95% CI=0.70-2.30%)로 나왔다. 우울과 인지기능 저하의 빈도가 유력 렘수면 행동장애 진단군에서 그렇지 않은 군에 비해 유의미하게 증가되었다. 결 론: 유력 렘수면 행동장애는 노년층에서 드물지 않은 질환이지만 이에 대한 인식은 부족한 실정이다. 유력 렘수면 행동장애의 평가와 치료에 대한 관심이 더욱 요구된다.

The change of sleep pattern is one of the most often altered normal physiological functions in elderly people. Besides normal change of sleep, insomnia and sleep apnea syndrome (SAS) are (one of) the main complaints. In addition, parasomnia is also frequent in this age group. Several parasomnias frequently found in the elderly are reviewed. Periodic limb movements in sleep (PLMS), restless legs syndrome (RLS), and REM sleep behavior disorder are the most frequent parasomnias in old age. Most parasomnias could be diagnosed by polysomnography, and be treated easily. Therefore, early and precise diagnosis and management for parasomnia in aging people are needed.

목 적 : 기면병과 렘수면 행동장애(RBD)에서 모두 신경 퇴행적 과정이 존재할 가능성과 함께 두 질환의 증상 사이에 공통점이 있다는 제안이 많이 있었다. 이 연구는 두 렘수면 관련 질환에서 스펙트럼 분석방법을 적용하여 렘수면 뇌파의 미세 차이에 관해 살펴 보고자 하였다. 방 법 : 기면병과 RBD 각 군에서 9명씩 성비를 맞추어 분석 대상자를 선정하였다. 각각의 분석대상자의 세 개의 렘수면 주기에서 각각 연속된 세 수면단위를 골라 한 사람당 9개의 수면단위에 대해 스펙트럼 분석을 실시하였다. 결 과 : 델타파 영역에서는 그 비율이 기면병군에서 RBD군보다 유의하게 높았다(p<0.01). 알파파(p=0.02)와 베타 2영역($20{\sim}50\;Hz$)에서는 RBD군에서 기면병보다 비율이 유의하게 높았다(p<0.01). 서파수면은 기면병에서 많았으나 양군간에 렘수면 분율의 차이는 없었다(p=0.93). 결 론 : 기면병의 렘수면에서 RBD에 비해 델타파의 비율이 높은 양상은 수면촉진기전이 기면병에서 좀 더 우세하게 작용하는 것을 반영하는 것이다.

Polysomnography is used to diagnose many types of sleep disorders including sleep apnea, periodic limb movement disorder, REM sleep behavior disorder, parasomnias, and narcolepsy. It is a comprehensive recording of the biophysiological changes that occur during sleep. The polysomnography monitors many body functions parameters including EEG, EOG, EMG, ECG, respiratory airflow, respiratory effort, and pulse oximetry during sleep. Multiple Sleep Latency Test (MSLT) is performed for diagnosing narcolepsy and excessive daytime sleepiness. It is usually to be done after an overnight polysomnography. The test consists of four or five 20-minute nap opportunities that are scheduled two hours apart.

Objectives: This study was performed to review the research trends in treatment for REM sleep behavior disorder (RBD) in Traditional Chinese Medicine (TCM) and Kampo in Japan. Methods: We searched articles in CNKI (China National Knowledge Infrastructure) under the key words, "RBD", and Chinese words related with it in Traditional Chinese Medicine, Traditional Chinese Medicinal Herbs and Combination of Traditional Chinese Medicine With Western Medicine' field, and also in CiNii (Citation Information by NII); we also searched articles in Kampo Square in Japan under the key words, "RBD" and Japanese words related with it. We found 10 papers, and then selected 6 of them except the non-clinical and unrelated studies. We then analyzed their way of diagnosis, treatments, study type and etc.. Results: 6 studies were divided into 4 case reports, one control study, and one literature review study. All of the studies reported that Herbal medicine for RBD was effective as much as Western medicine like clonazepam and paroxetine. However, the quality and the quantity of these clinical studies were not enough. Conclusions: It seems that the researches for RBD have gradually been performed in TCM and Kampo. We hope that our study can activate/push forward clinical research for this disorder in Korean traditional medicine.

Periodic limb movements during sleep (PLMS) are prevalent in various sleep disorders, such as restless legs syndrome (RLS), periodic limb movements disorder, obstructive sleep apnea (OSA), REM sleep behavior disorder (RBD), and narcolepsy. PLMS has been hypothesized to be related to the decline of dopaminergic transmission. In RLS, PLMS is suggested to be related to iron deficiency and symptom severity. PLMD is a rare sleep disorder, and the role of PLMS in PLMD has not been clearly investigated yet. PLMS in OSA, which remain after proper PAP therapy, may need further management. The clinical relevance of PLMS in RBD and narcolepsy have not been investigated thoroughly and need further studies. Whether PLMS are to be considered as a mere symptom of individual sleep disorders or not can be elucidated through studies investigating the efficacy of therapeutic approaches to reduce PLMS in various sleep disorders.

Sleep changes substantially with age. There is a phase advance in the circadian sleep cycle and increased waking after sleep onset. The elderly people wake more frequently during the night and experience fragmented sleep and excessive daytime sleepiness. The prevalence of sleep disorders increases with age, and the composition of sleep disorders in the elderly differs from that in the young. The most frequently encountered sleep disorders are psychophysiologic insomnia, sleep disturbance due to dementia, sleeprelated respiratory disorder, restless legs syndrome and periodic limb movement disorder, and REM sleep behavior disorder. To treat the elderly sleep problem appropriately, it is important to know how sleep pattern changes as we age and to understand the cause of sleep-related symptoms. This article will review the sleep physiology and common sleep disorders in the elderly.
