However, ICSD-2 criteria did not suggest validated diagnostic criteria and previous studies had no consistency with value ranged 10-20% of REM sleep without atonia (RSWA) in polysomnography (PSG). We investigated standard value about RSWA of Korean RBD patients. Methods: Thirty one patients diagnosed with RBD and 31 normal ageand sex-matched controls were selected. All RBD patients and normal controls were studied using PSG from 2007 to 2012. ICSD-2 criteria was used to select RBD patients and RSWA. We defined RSWA as increasing amplitude by 4 times that of baseline EMG and occupying at least 50% of each epoch or five 3 second mini-epochs. Results: PSG findings showed increased N1 sleep, periodic leg movement index and decreased N2 sleep in RBD patients compared to normal controls. Mean RSWA was 19.21% [±9.93, standard deviation (SD)], with a range of 5.21-38.22% in RBD patients, whereas the mean RSWA in normal control was 0.43% (±0.74, SD) with a range of 0-2.3%. Conclusions: We quantitatively figured out the characteristics of PSG and RSWA in Korean RBD patients. The outcome shows definite differences between RBD patients and normal controls. This study suggest that we may diagnose RBD who have RSWA over 5% of the REM sleep periods.

Light emitting diode (LED) light is becoming recognized as one of the most promising general sources of illumination. We conducted spectral power analysis of electroencephalograms (EEGs) obtained during resting and cognitive task activities to identify the effects on human arousal and cognitive performance under LED light compared with conventional fluorescent light. Methods: Thirteen healthy, right-handed students participated in the present study. Each subject took part in two experimental sessions, one under fluorescent and one under LED lighting conditions. The experimental measurements consisted of a resting state EEG, an event-related potential (ERP) during a visual working memory (VWM) task, and a questionnaire about subjective feelings regarding the lighting conditions. The EEG power spectra, the amplitude and latency of the P300 ERP component, the behavioral responses for the VWM task, and the questionnaire data were compared for the two lighting conditions. Results: The EEG spectral power showed no difference between the LED and fluorescent lighting conditions. The amplitude of the P300 component decreased significantly with increasing numbers of items, while there were no differences between the two lighting conditions. Additionally, behavioral responses and subjective feelings were the same under the two lighting conditions. Conclusions: Our study suggests that there are no significant differences between LED light and fluorescent light on the human arousal state and VWM.

However, it’s debatable which affects their QOL more, disturbing pain or poor sleep quality. We investigated the factors that influence the QOL in patients with RLS, and compared the results to those of patients with chronic osteoarthritis (OA) who were having similar physical discomfort. Methods: This is a prospective case-control study comparing the QOL of 153 RLS patients with those of 153 OA patients. To evaluate the degree of physical discomfort, the QOL and the quality of sleep, all subjects completed various questionnaires, which included the SF-36, the Visual Analogue Scale for pain, Korean versions of the Pittsburg Sleep Quality Index and the Epworth Sleepiness Scale, and the insomnia severity index. We used the χ-test, t-test, analysis of covariance, Pearson’s correlation, multiple stepwise regression methods for analysis. Results: The QOL in patients with RLS was higher than those with OA, though pain severity (physical discomfort) was similar in both groups. However, the quality of sleep in RLS patients was poorer than those with OA. Through multiple stepwise regression analysis, we can recognize that the most important factor affecting the QOL in RLS patients was the severity of their physical symptoms. Conclusions: We found the quality of sleep had less of an influence on the QOL than the physical discomfort of the patients with RLS.

Methods: We enrolled the consecutive 53 patients with untreated RBD confirmed by ICSD-2 criteria. All patients showed typical sleep related injurious or disruptive behavior on history and REM sleep without atonia was revealed in polysomnography (PSG). Results: Male (n=38) to female (n=15) ratio was 2.53 : 1. Mean age of RBD onset and age of diagnosis was 58.9 yrs and 62.9 yrs, respectively. The age of diagnosis was not different but the age of onset was younger in female. Twenty two (41.5%) showed sleep-related injury to self or bed partner in history. Twenty seven (50.9%) showed dream acting out using proximal muscle in PSG. Among them, 12 (44.4%) could recall their dream. Two patients with RBD met the diagnostic criteria of Parkinson’s disease. Nine patients who underwent the University of Pennsylvania Smell Identification test in any reason showed anosomia (n=1) or hyposomia (n=8). PSG showed increased N1, normal N2, decreased N3 and preserved REM sleep. Twentytwo (41.5%) patients could be diagnosed with obstructive sleep apnea (OSA). Conclusions: We identified 53 patients with RBD confirmed with both clinical history and polysomnography. This study shows a higher proportion of female cases, and less association with neurodegenerative disease than earlier reports. OSA prevalence in RBD seems to be higher in this study compared with general population.
