Sleep problems in early infants tend to be persistent and prominent in preschool and school-aged children. Chronic sleep disorders, especially in young children may lead to neurobehavioral problems and psycho-cognitive impairment. Sleep difficulties may be the result of underlying medical conditions, （breathing disorders） or psychological problems. Research studies have shown the association between sleep disorders and day time cognitive impairment, behavioral problems, poor school performance and inattention in children. Appropriate diagnosis and early management of sleep disorders in children lead to improvement of neurocognitive function and behavioral problems in these children.展开更多

However, voxel-based morphological studies evaluating structural abnormalities in the brains of iRBD patients are relatively rare. This study aimed to explore cerebral structural alterations using magnetic resonance imaging and to determine their association with clinical parameters in iRBD patients. Brain structural T1-weighted MRI scans were acquired from 19 polysomnogram-confirmed iRBD patients(male:female 16:3; mean age 66.6 ± 7.0 years) and 20 age-matched healthy controls(male:female 5:15; mean age 63.7 ± 5.9 years). Gray matter volume(GMV) data were analyzed based on Statistical Parametric Mapping 8, using a voxel-based morphometry method and two-sample t-test and multiple regression analysis. Compared with controls, iRBD patients had increased GMV in the middle temporal gyrus and cerebellar posterior lobe, but decreased GMV in the Rolandic operculum, postcentral gyrus, insular lobe, cingulate gyrus, precuneus, rectus gyrus, and superior frontal gyrus. iRBD duration was positively correlated with GMV in the precuneus, cuneus, superior parietal gyrus, postcentral gyrus, posterior cingulate gyrus, hippocampus, lingual gyrus, middle occipital gyrus, middle temporal gyrus, and cerebellum posterior lobe. Furthermore, phasic chin electromyographic activity was positively correlated with GMV in the hippocampus, precuneus, fusiform gyrus, precentral gyrus, superior frontal gyrus, cuneus, inferior parietal lobule, angular gyrus, superior parietal gyrus, paracentral lobule, and cerebellar posterior lobe. There were no significant negative correlations of brain GMV with disease duration or electromyographic activity in iRBD patients. These findings expand the spectrum of known gray matter modifications in iRBD patients and provide evidence of a correlation between brain dysfunction and clinical manifestations in such patients. The protocol was approved by the Ethics Committee of Huashan Hospital(approval No. KY2013-336) on January 6, 2014. This trial was registered in the ISRCTN registry(ISRCTN18238599).展开更多

The association between these two conditions has been contradictory. The aim of this study is to analyze the association between these two non-motor symptoms. Methods: Consecutive subjects with Parkinson’s disease attending the Movement Disorders Outpatient Clinic were included. The presence of ICDs was assessed using the Questionnaire for Impulse Control Disorders Rating Scale. RBD was diagnosed by an overnight, single night polysomnography. Results: Fifty-five consecutive subjects with Parkinson’s disease were included. The prevalence of ICDs and related behaviors was 23.6% (ICD in 14.5% and related behaviors in 9.1%). RBD was diagnosed in 47.2% of the patients. No differences were found in the frequency of ICDs and related behaviors when comparing subjects with and without RBD (23% versus 24.1%, p = 0.926, respectively). Conclusion: No association between the presence of RBD and the frequency of ICDs in subjects with Parkinson’s disease was found.展开更多

文摘目的快速眼动睡眠行为障碍(rapid eye movement sleep behavior disorder,RBD)是帕金森病(Parkinson's disease,PD)常见的非运动症状且是重要预后因素。本研究通过静息态功能磁共振成像,利用度中心度(degreecentrality,DC)和低频振幅(amplitudes of low-frequency fluctuation,ALFF)分析PD伴RBD和不伴有RBD患者组以及健康对照组三组间DC值和ALFF值,探索PD伴RBD患者脑功能活动特征及RBD特异性脑区,探究RBD发生的病理机制。材料与方法招募20例伴有RBD的PD患者(PD-RBD组)、40例无RBD的PD患者(PD-nonRBD组)和44例年龄性别匹配的健康对照(健康对照组),三组被试均接受磁共振扫描。利用静息态数据计算DC值和ALFF值,探测脑功能特征。结果方差分析结果显示三组间DC值主效应脑区为右侧中央前回、颞上回、小脑、额中回(P<0.05,FDR校正);ALFF值主效应脑区为左侧海马旁回、楔叶、舌回(P<0.05,FDR校正)。进一步分析发现相比于PD-nonRBD组,PD-RBD患者表现为右侧额中回DC值升高(t=4.02;P=0.007,FDR校正);左侧楔前叶DC值降低(t=5.30;P=0.009,FDR校正)。相比于健康对照组,PD-RBD患者表现为左侧额上回、小脑、右侧颞上回、左侧颞中回、额中回的DC值升高(P<0.05,FDR校正);左侧中央前回、颞上回和颞中回的DC值降低(P<0.05,FDR校正);右侧楔叶ALFF值降低(P<0.05,FDR校正)。结论PD-RBD在DC和ALFF上有独特的影像学特征,特别是右侧额中回、左侧楔前叶的功能异常可能与PD患者RBD的发生密切相关。
