It is frequently used for its mood and performance enhancing effects. The daily caffeine intake of Korean university students and North American adults are approximately 120 mg and 200 mg, respectively. Caffeine increases vigilance and diminishes sleepiness, and administration of these doses stimulates attention and restores performance degraded by factors such as fatigue and boredom. Central stimulating effects of caffeine have been evaluated by quantitative electroencephalography (qEEG) analysis. Although many studies have used qEEG analysis, inconsistencies still remain regarding the effects of caffeine on electroencephalography (EEG) spectral powers. These inconsistencies could be attributed to experimental differences between studies. Many studies have been conducted to clarify the effects of various parameters, such as, dose-dependency, eyes open or closed, and vigilance control. However, recording duration for qEEG analysis has not been well considered. According to multiple sleep latency test (MSLT) studies, sleep latency in normal adults during the day is around 15 min. Considering that the duration of the EEG recordings are generally 10–30 min, sleep can occur during recording and thus EEG rhythms can change. Accordingly, the selection of a part from a recording for qEEG analysis can affect the outcome of studies on the effects of caffeine on EEG spectral powers. In contrast to subjective questionnaires or neuropsychological tests, qEEG analysis has the advantage of being able to provide objective descriptions of temporal changes. Therefore, we examined the effect of caffeine effect on temporal change by qEEG by dividing the recording period into two segments and by comparing the qEEG parameters of","PeriodicalId":243131,"journal":{"name":"Journal of Korean Sleep Research Society","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128382660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, RBD may also occur in acute or subacute conditions involving the central nervous system, for example structural lesions, encephalitis, Guillain-Barre syndrome, drug and alcohol withdrawal. Three patients developed RBD after acute inflammatory encephalitis, which lasted for 3 months to 1 year. They talked, moved and walked nightly while asleep. During night polysomnography, there were REM sleep without atonia and abnormally increased REM sleep as 37–87% of total sleep. The RBD improved with clonazepam and there was no recurrence at 1 year follow-up. The global encephalitis could be responsible for the RBD and destruction of sleep architecture.

Although dopamine agonists improve RLS sensory symptoms and periodic leg movements during sleep, there was no study regarding the effects of dopamine agonist on cognition in patients with RLS. Methods: Sixteen drug-naive RLS patients were enrolled. They underwent sleep questionnaires, Beck Depression Inventory, and neuropsychological evaluation, consisting of Rey Complex Figure Test and recognition trial (RCFT), Korean-California Verbal Learning Test, Controlled Oral Word Association Test (COWAT) before and after treatment with pramipexole (PMP). PMP was administered over a period of 12 weeks every night 1 h before bedtime. Paired Student’s t-test and Spearman’s correlation analysis were used for analyses. Results: After treatment with PMP, the International RLS Severity Scale score was significantly decreased. Sleep quality and depression also significantly improved after the treatment. RCFT immediate recall, COWAT phoneme word frequency, and digit symbol coding scores significantly improved compared to those before the treatment (17.72±7.84 vs. 20.13±7.33, p=0.05; 36.50±12.62 vs. 41.50±12.58, p=0.03; 68.19±21.11 vs. 73.81±21.11, p=0.02, respectively). There were no significant correlations between changes in clinical variables and in cognitive functions before and after the treatment. Conclusions: This study suggests that treatment with PMP in RLS patients improves not only RLS sensory symptoms, but also cognitive functions.

Several studies showed that sleep quality impacts on cognitive function, psychiatric symptoms, and quality of life. The purpose of this study is to evaluate the interrelations of quality of sleep, depressive symptoms, and quality of life in idiopathic Parkinson’s disease (IPD). Methods: We enrolled 69 patients with IPD who had visited our clinic. IPD was diagnosed by UK Parkinson’s Disease Society brain bank clinical diagnostic criteria. We assessed by Pittsburgh Sleep Quality Index (PSQI), Korean Mini-Mental State Examination, Clinical Dementia Rating, Geriatric Depression Scale (GDS), and 36-item Short-Form Health Survey (SF-36). Results: Poor sleep quality was defined by PSQI score 6 or above. Therefore, 36 patients (52.2%) of subjects had poor sleep quality. There were no significant differences in the demographics. The patients with poor sleep quali ty showed more cognitive dysfunction and depressive symptoms than those with good sleep quality. The PSQI scores significantly correlated with GDS and SF-36 scores. Also, quality of sleep exerted negative ef fect on quality of life and quality of life exerted negative effect on depressive symptoms. Conclusions: This study showed that there were significant interrelations among quality of sleep, depressive symptoms, and quality of life.

Our object is to compare the general feature and sleep apnea characteristics between OSA with and without mixed breathing pattern. Methods: Total 244 patients who were diagnosed as OSA [apnea-hypopnea index (AHI) ≥5 /h] were studied retrospectively. Mixed breathing pattern was defined as mixed apnea index plus central apnea index (MCAI) with ≥5 /h (Mix-OSA). OSA without mixed breathing pattern (Non-mix-OSA) was defined with MCAI with <5 /h. Central sleep apnea syndrome was excluded. We investigated differences of the distribution and shifting of apnea index across sleep stage, position and sleep time between Mix-OSA and Non-mix-OSA group. Results: The prevalence of Mix-OSA was 42 of 244 OSA patients (17.2%). There were no significant differences in demographics except higher AHI in Mix-OSA group. Mix-OSA showed a significant increment of MCAI and hypopnea index during non rapid eye movement sleep while Non-mix-OSA showed increased obstructive apnea index (OAI) in rapid eye movement sleep period. In both groups, supine body position was related to high OAI. There were no meaningful differences in sleep apnea according to the timing of sleep in both groups. Conclusions: OSA patients with mixed breathing pattern had more severe OSA than Non-mix-OSA. There were some significant differences in sleep apnea characteristics between OSA with and without mixed breathing pattern. However, their clinical significance still remains unclear.
