Rapid eye movement (REM) sleep behavior disorder (RBD) is frequently observed in patients with Parkinson's disease (PD). Accurate diagnosis is essential for managing this condition. Furthermore, the emergence of idiopathic RBD in later life can represent a premotor feature, heralding the development of PD. Reliable, accurate methods for identifying RBD may offer a window for early intervention. This study sought to identify whether the RBD screening questionnaire (RBDSQ) and three questionnaires focused on dream enactment were able to correctly identify patients with REM without atonia (RWA), the neurophysiological hallmark of RBD. Forty‐six patients with PD underwent neurological and sleep assessment in addition to completing the RBDSQ, the RBD single question (RBD1Q), and the Mayo Sleep Questionnaire (MSQ). The REM atonia index was derived for all participants as an objective measure of RWA. Patients identified to be RBD positive on the RBDSQ did not show increased RWA on polysomnography (80% sensitivity and 55% specificity). However, patients positive for RBD on questionnaires specific to dream enactment correctly identified higher degrees of RWA and improved the diagnostic accuracy of these questionnaires. This study suggests that the RBDSQ does not accurately identify RWA, essential for diagnosing RBD in PD. Furthermore, the results suggest that self‐report measures of RBD need to focus questions on dream enactment behavior to better identify RWA and RBD. Further studies are needed to develop accurate determination and quantification of RWA in RBD to improve management of patients with PD in the future. © 2014 International Parkinson and Movement Disorder Society 相似文献

目的研究伴与不伴快动眼睡眠行为障碍(rapid eye movement sleep behavior disorder,RBD)的帕金森病(Parkinson disease,PD)患者的震颤特征及多巴反应性。方法根据2014年国际睡眠障碍分类第三版RBD的临床最低诊断标准,本研究采用RBD筛查问卷(RBD screening questionnaire,RBDSQ)量表来诊断临床很可能RBD(clinically probable RBD,cpRBD),将PD患者分为伴有cpRBD的PD(PD+cpRBD)与不伴有cpRBD的PD(PD-cpRBD)两组。对入组患者进行一般资料的收集,采用修订的H-Y分级、统一帕金森评分量表3.0版运动检查部分(UPDRS-Ⅲ)、MDS-UPDRS震颤量表对患者的运动功能进行评估,并且分别对两组患者首发侧肢体姿势性震颤、动作性震颤及静止性震颤的幅度进行评分,比较两组患者一般资料及震颤特征的差异性。对所有患者行急性左旋多巴冲击试验,将两组患者UPDRS-Ⅲ及MDS-UPDRS震颤量表评分最大改善率进行比较。结果共纳入42例伴有震颤的PD患者,PD+cpRBD组19例,PD-cpRBD组共23例,两组患者在性别、年龄、发病年龄、病程、关期UPDRS-Ⅲ评分及H-Y分级方面均无明显差异(P0.05)。与PD-cpRBD组相比,PD+cpRBD组关期震颤评分明显增高(t=2.379,P=0.022),震颤症状由首发侧肢体进展至对侧肢体的时间短(u=-2.133,P=0.033),首发侧肢体静止性震颤幅度大(u=-2.956,P=0.003),动作性震颤幅度大(u=-2.657,P=0.008)。口服左旋多巴/苄丝肼(200/50 mg)后,PD-cpRBD组的UPDRS-Ⅲ及震颤评分最大改善率均明显高于PD+cpRBD组(UPDRS-Ⅲ最大改善率u=-3.134,P=0.002;震颤评分最大改善率t=-3.189,P=0.003)。结论本研究表明,伴有cpRBD的PD患者震颤程度相对较重,以静止性震颤和动作性震颤为主,由首发侧肢体进展至对侧肢体的时间相对较短,对左旋多巴的反应性较差。 相似文献

Objective
Rapid eye movement (REM) sleep behavior disorder (RBD) is a risk factor for dementia in Parkinson disease (PD) patients. The objectives of our study were to prospectively evaluate the frequency of RBD in a sample of treatment-naïve, newly diagnosed PD patients and compare sleep characteristics and cognition in RBD and non-RBD groups.Methods
Fifty-seven newly diagnosed PD patients were consecutively recruited in a university medical center. All patients underwent two overnight polysomnography (PSG) sessions and were diagnosed with RBD according to the International Classification of Sleep Disorders, Second Revision criteria. Daytime sleepiness was measured in a multiple sleep latency test (MSLT). Cognition was assessed in a standard neuropsychologic examination.Results
Seventeen PD patients (30%) met the criteria for RBD. The RBD patients and non-RBD patients did not significantly differ in mean age, gender ratio, disease duration, motor symptom subtype and severity, total sleep time, percentage of REM sleep, apnea–hypopnea index, mean oxygen saturation, and importantly cognitive performance. However, non-RBD patients had a significantly shorter mean daytime sleep latency than RBD patients (15 vs 18 min, respectively; P = .014).Conclusion
A high frequency of RBD was found in our sample of 57 newly diagnosed PD patients. At this stage in the disease, RBD was not found to be associated with other sleep disorders or cognitive decline. Follow-up is needed to assess the risk for developing dementia in early-stage PD patients with RBD. 相似文献8.

ObjectiveRapid eye movement sleep behavior disorder (RBD) is a common sleep disturbance in patients with neurodegenerative disorders. We aimed to compare sleep parameters among the different types of RBD patients.MethodsA total of 122 patients with dream enactment behavior were screened. Of these, 92 patients who were diagnosed with RBD by polysomnography were included in this study. Enrolled patients with RBD were classified into four groups based on the following diagnoses: idiopathic RBD (iRBD); RBD with Parkinson disease (PD-RBD); multiple system atrophy (MSA) with RBD (MSA-RBD); and dementia with Lewy bodies (DLB) with RBD (DLB-RBD). Various clinical and polysomnographic parameters were compared.ResultsAmong the 92 patients with RBD, 35 had iRBD, 25 had PD-RBD, 17 had MSA-RBD, and 15 had DLB-RBD. The mean apnea−hypopnea index of atypical parkinsonism with RBD (AP-RBD) group was 16.2 ± 17.7 events/h (MSA-RBD, 14.0 ± 16.6; DLB-RBD, 18.8 ± 19.1), which was significantly higher than the other groups (p < 0.05). The proportion of patients with 100% supine sleep in the AP-RBD group (44%) was higher than that in the iRBD group (14%; p = 0.030). The proportion of OSA with 100% supine sleep position was significantly higher in the MSA-RBD and DLB-RBD groups than in the iRBD group (p = 0.042 and p = 0.029, respectively).ConclusionOur study demonstrated that patients in the MSA-RBD and DLB-RBD groups had a tendency to sleeping in the supine position and a higher vulnerability to OSA compared to other RBD groups. Further cohort studies are needed to evaluate the influence of these factors on the development of parkinsonism. 相似文献

BackgroundRapid eye movement sleep behavior disorder (RBD) is common in Parkinson disease (PD).ObjectivesTo determine the frequency of clinically probable RBD (cpRBD) in young-onset (21 to ⩽40 years; YOPD) and older-onset PD (>40 years; OOPD) and characterize its pattern.MethodsA total of 156 patients with PD (YOPD-51, OOPD-105) were clinically examined and the presence of RBD was diagnosed using the minimal criteria for diagnosis of RBD (International Classification of Sleep Disorders, ICSD-1). RBD screening questionnaire based on the minimal criteria was used. The bed-partners were also interviewed with Mayo sleep questionnaire. Other scales included Unified Parkinson Disease Rating Scale part III (UPDRS III), Hoehn & Yahr stage, Mini Mental Status Examination, Pittsburgh Sleep Quality Index, Parkinson Disease Sleep Scale, Epworth Sleep Scale, Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale.ResultscpRBD was diagnosed in 30 (19.2%) patients, majority being OOPD rather than YOPD (86.7% vs 13.3%; P = 0.01). The frequency of RBD was significantly higher (P = 0.016) in OOPD (24.8%) compared to those with YOPD (7.8%). Most often (72.4%) RBD occurred after the onset of parkinsonian symptoms. RBD was independently associated with higher global PSQI scores, total ESS scores and total PDSS scores after adjusting for the effects of age, gender, Hoehn & Yahr stage and duration of illness.ConclusionsPatients with RBD were older with later-onset motor symptoms, a more advanced stage, poorer sleep quality, and more frequent daytime sleepiness. Older-onset PD had a higher frequency of RBD than young-onset PD. 相似文献

Objective
We aimed to compare rhythmic masticatory muscle activity typical of sleep bruxism and oromandibular myoclonus (OMM) during rapid eye movement (REM) sleep in patients with idiopathic REM sleep behavior disorder (iRBD) and in Parkinson disease (PD) patients with RBD (PD-RBD).Methods
Sleep polygraphic data were collected from 9 age-matched controls and 28 patients (mean ± standard error of the mean, 66.0 ± 1.7 y) with a clinical and sleep laboratory diagnosis of RBD. Patients were divided into two groups: 13 patients with iRBD and 15 patients with PD-RBD. Rhythmic masticatory muscle activity, a marker of sleep bruxism, and OMM were scored blind to subject’s diagnosis from jaw electromyographic recordings during sleep.Results
The rhythmic masticatory muscle activity index was significantly higher during REM sleep in iRBD subjects compared to controls (P < .01) and was significantly higher during non-REM (NREM) sleep in both subject groups compared to controls (P ? .03). A positive sleep laboratory diagnosis of sleep bruxism was made in 25% of all patients. In iRBD, patients had more OMM during REM sleep than controls (2.4 times higher; P = .01).Conclusion
In the presence of a high frequency of rhythmic masticatory muscle activity during REM sleep, RBD may be suspected and further neurologic assessment is recommended. 相似文献12.
Rapid eye movement sleep behavior disorder (RBD) is common in Parkinson’s disease (PD). Little information exists about RBD in women with PD. The aim of this study was to determine the clinical expression of RBD in women with PD and note any differences in women with PD with and without RBD. One hundred fifty-six patients with PD were recruited. There were 37 women with PD and probable RBD was diagnosed using the RBD Screening Questionnaire. Other scales included Pittsburgh Sleep Quality Index, Parkinson’s Disease Sleep Scale, Epworth Sleep Scale, Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale. Probable RBD was diagnosed in 10 women with PD (27%). Most often (70%) RBD occurred after the onset of parkinsonian symptoms. Women with probable RBD were older, had shorter duration of PD symptoms, lower tremor score, and higher axial signs score. They had insomnia (80% versus non-probable RBD patients 44%, p = 0.019), and poor sleep quality with excessive daytime sleepiness. Anxiety and depression were common in women with probable RBD. Episodes were brief and confined to vocalization and simple limb movements. No injury to self or bed partners was noted. Women with PD have fewer fights and less aggressive dream enacting behaviour than men, but suffer from significant disturbed sleep, and levels of anxiety and depression. 相似文献

Background: MAPT haplotypes are associated with PD, but their association with rapid eye movement sleep behavior disorder is unclear. Objective: To study the role of MAPT variants in rapid eye movement sleep behavior disorder. Methods: Two cohorts were included: (A) PD (n = 600), rapid eye movement sleep behavior disorder (n = 613) patients, and controls (n = 981); (B) dementia with Lewy bodies patients with rapid eye movement sleep behavior disorder (n = 271) and controls (n = 950). MAPT‐associated variants and the entire coding sequence of MAPT were analyzed. Age‐, sex‐, and ethnicity‐adjusted analyses were performed to examine the association between MAPT, PD, and rapid eye movement sleep behavior disorder. Results: MAPT‐H2 variants were associated with PD (odds ratios: 0.62‐0.65; P = 0.010‐0.019), but not with rapid eye movement sleep behavior disorder. In PD, the H1 haplotype odds ratio was 1.60 (95% confidence interval: 1.12‐2.28; P = 0.009), and the H2 odds ratio was 0.68 (95% confidence interval: 0.48‐0.96; P = 0.03). The H2/H1 haplotypes were not associated with rapid eye movement sleep behavior disorder. Conclusions: Our results confirm the protective effect of the MAPT‐H2 haplotype in PD, and define its components. Furthermore, our results suggest that MAPT does not play a major role in rapid eye movement sleep behavior disorder, emphasizing different genetic background than in PD in this locus. © 2018 International Parkinson and Movement Disorder Society 相似文献

快速眼动睡眠期行为障碍系指快速眼动睡眠期肌肉失弛缓,并出现梦境(通常是暴力梦境)相关肢体运动(梦境演绎行为)。其人群发病率为0.38%~2.01%,在神经变性病尤其是α-突触核蛋白病患者中的发病率明显增加。快速眼动睡眠期行为障碍可早于α-突触核蛋白病数十年出现,因此可以作为预测神经变性病的早期标记。本文拟就近年来关于快速眼动睡眠期行为障碍发病机制及其与神经变性病之间的关系进行简要综述。 相似文献

INTRODUCTION: REM sleep behavior disorder (RBD) is a parasomnia characterized by a loss of atonia and an increased phasic muscle activity during REM sleep. Idiopathic RBD frequently herald an alpha-synucleinopathy, including such as Parkinson's disease (PD) and dementia with Lewy Body (DLB). Pathological changes in the anterior olfactory nucleus and olfactory loss occur very early in the course of PD and DLB. The aim of the study was to assess olfactory function in a large group of idiopathic RBD patients. METHODS: Fifty-four consecutive polysomnographically-confirmed iRBD patients (44 men, 10 women; mean age: 69.2+/-8.3 years; mean Unified Parkinson's Disease Rating Scale Part III (UPDRS-III) score: 4.9+/-4.3) and 54 age and gender-matched control subjects underwent the Brief University of Pennsylvania Smell Identification Test (B-SIT). RESULTS: A marked olfactory impairment was observed in the RBD group (mean B-SIT score: 7.1+/-2.5 versus 9.4+/-1.8; p < 0.0001), with 33 (61.1%) RBD patients versus 9 (16.6%) controls showing abnormal olfactory function (p < 0.0001). No correlation was found between the degree of olfactory loss and either duration of RBD symptoms or UPDRS-III score. Deficit in recognize paint thinner odorant showed the highest positive predictive value (0.95) for identifying idiopathic RBD. CONCLUSIONS: The olfactory deficit found in most idiopathic RBD patients shares similarities with that described in PD and may be a sign of a widespread neurodegenerative process. Its detection may help in identifying subjects at higher risk of developing an alpha-synucleinopathy-mediated neurodegeneration. 相似文献

IntroductionThe relationship between ICD and RBD is still not yet understood and the results from the current literature are contradictory in PD. We aimed to explore the association between rapid eye movement (REM) sleep behavior disorder (RBD) and impulse control disorder in Parkinson's disease.MethodsNinety-eight non-demented patients with Parkinson's disease underwent one night of video-polysomnography recording. The diagnosis of RBD was established according to clinical and polysomnographic criteria. Impulse control disorders were determined by a gold standard, semi-structured diagnostic interview.ResultsHalf of the patients (n = 49) reported clinical history of RBD while polysomnographic diagnosis of RBD was confirmed in 31.6% of the patients (n = 31). At least one impulse control disorder was identified in 21.4% of patients, 22.6% with RBD and 20.9% without. Logistic regression controlling for potential confounders indicated that both clinical RBD (OR = 0.34, 95% CI = 0.07–1.48, P = 0.15) and polysomnographic confirmed RBD diagnoses (OR = 0.1.28, 95% CI = 0.31–5.33, P = 0.34) were not associated with impulse control disorder.ConclusionIn Parkinson's disease, REM Sleep Behavior Disorder is not associated with impulse control disorder. The results of our study do not support the notion that PSG-confirmed RBD and ICD share a common pathophysiology. 相似文献

REM sleep behavior disorder (RBD) is commonly associated with Parkinson disease (PD), but it is unclear whether this association has implications for disease manifestations. We evaluated 36 PD patients for the presence of RBD by polysomnography. Patients underwent an extensive evaluation by a movement disorders specialist blinded to polysomnography results. Severity of motor manifestations, autonomic, visual, psychiatric, and olfactory dysfunctions and quality of life (QOL) were assessed, and compared using regression analysis that adjusted for disease duration, age and sex. Severity of motor manifestations did not differ between groups. However, the presence of RBD in PD was strongly associated with symptoms and signs of orthostatic hypotension (systolic blood pressure lying to standing = ?25.7 ± 13.0 mmHg vs. ?4.9 ±14.1, P < 0.001); and orthostatic symptom prevalence = 71% vs. 27%, P = 0.0076). There was no association between RBD and other autonomic symptoms. Color vision was worse in patients with RBD, but olfactory dysfunction did not differ between groups. The prevalence of depression, hallucinations, paranoia, and impulse disorders did not differ between groups. Emotional functioning and general health QOL measures were lower in those with RBD, but there were no differences between groups on disease‐specific indices or on measures of overall physical QOL. These findings suggest that the pathophysiology of RBD and nonmotor manifestations of PD, particularly autonomic dysfunction, are linked. © 2008 Movement Disorder Society 相似文献
