There are a multitude of sleep-wake disturbances that worsen the patient’s quality of life, insomnia and excessive daytime sleepiness being two of the most frequent complaints. The aim of this review is to highlight the most relevant clinical trials conducted during the last 5 years, focusing on the problematic of insomnia and daytime sleepiness correlated with Parkinson’s Disease and its treatment. Three electronic databases (Pubmed, Science Direct and Google Scholar) were searched during March and April 2020 for articles on this topic, finally selecting 21 most relevant articles that we have included in this review. Interesting aspects regarding correlation between sleep-wake disorders and Parkinson’s disease were found, showing that non-motor symptoms may be independent of the disease itself. We discussed the most recent advances in treatment opportunities and the adverse effects, with insomnia and daytime sleepiness among the most common complaints. Besides newly developed pharmacological therapy, consisting in mostly dopaminergic agonists or levodopa adjuvant drugs. Other possibly effective therapies on sleep-wake disorders such as deep brain stimulation, dietary changes, bright light therapy and alternative medicine protocols are also reviewed. Insomnia and excessive daytime sleepiness are common complaints in Parkinson’s disease patients, being either self-standing non-motor symptoms or adverse effects of the antiparkinsonian medication, diminishing patient’s quality of life. The effervescence of research on this topic shows promising results, with new clinical trials still to come in the near future.展开更多

Therefore, early detection of EDS is critical in disease management. We examined the association between Epworth Sleepiness Scale （ESS） and multiple sleep latency test （MSLT） and diagnostic accuracy of ESS in assessing EDS in OSAHS patients. Methods The ESS, MSLT and overnight polysomnography were administered to 107 Chinese patients to assess EDS and its correlations with polysomnographic parameters. The diagnostic accuracy of ESS in classifying EDS （mean sleep latency （MSL） 〈10 minutes） was evaluated by calculating the area under ROC curve. Results As the severity of OSAHS increased, MSL decreased with increase in ESS score. Conversely, patients with worsening EDS （shorter MSL） were characterized by advanced nocturnal hypoxaemia and sleep disruption compared to those with normal MSL, suggesting EDS is associated with more severe OSAHS. There was a negative correlation between ESS score and MSL and both moderately correlated with some polysomnographic nocturnal hypoxaemic parameters. The area under ROC curve of ESS for identifying EDS was 0.80 （95% CI： 0.71 to 0.88） and ESS score 〉12 provided the best predictive value with a sensitivity of 80% and specificity of 69%. Conclusion The ESS score moderately correlates with MSL and our ROC study supports ESS as a screening strategy for assessing EDS in OSAHS.展开更多

This review summarized recent studies on the epidemiology, etiology, clinical implications, associated features, and evaluation of EDS in PD. The efficacy of pharmacologic and non-pharmacologic treatments for EDS in PD was also reviewed.Data Sources：English language articles indexed in PubMed and Cochrane databases and Chinese-language papers indexed in Wanfang and National Knowledge Infrastructure databases that were published between January 1987 and November 2017 were located using the following search terms： ＂sleepiness＂ , ＂sleep and Parkinson’s disease＂ , and ＂Parkinson’s disease and treatment＂ .Study Selection：Original research articles and critical reviews related to EDS in PD were selected.Results：EDS is a major health hazard and is associated with many motor and nonmotor symptoms of PD. Its causes are multifactorial. There are few specific guidelines for the treatment of EDS in PD. It is first necessary to identify and treat any possible factors causing EDS. Recent studies showed that some nonpharmacologic （i.e., cognitive behavioral therapy, light therapy, and repetitive transcranial magnetic stimulation） and pharmacologic （i.e., modafinil, methylphenidate, caffeine, istradefylline, sodium oxybate, and atomoxetine） treatments may be effective in treating EDS in PD.Conclusions：EDS is common in the PD population and can have an immensely negative impact on quality of life. Its causes are multifactorial, which complicates its treatment. Further investigations are required to determine the safety and efficacy of potential therapies and to develop novel treatment approaches for EDS in PD.展开更多

Methods: According to the methodology, 154 students participated in the research, attending from the first to the sixth year of the course. The Pittsburg Sleep Quality Index questionnaire and the Epworth sleepiness scale were applied. Descriptive statistics techniques were applied and demonstrated in the form of tables and graphs. The comparison of variables was carried out using statistical tests. Results: The results showed that most students do not sleep very well. It was observed that 68.83% of a total of 106 students are bad sleepers. Conclusion: It is concluded that medical students sleep a low number of hours by period, which could interfere in impairment of attention, learning and memory formation, interfering in academic performance. On the other hand, they showed greater daytime sleepiness compared to the general population.展开更多

Mandibular advancement devices (MAD) are proven to be efficient in treating mild to moderate sleep apnea and snoring. We examined patients who had been treated in Community Dental Care with a titrable Herbst-type MAD. The aim of the study was to evaluate the quality of sleep based on self report. Methods: A questionnaire was mailed to patients (n = 184) who had received treatment for OSA or snoring between 2007 and2010 inthe Helsinki Health Centre Oral Care Unit. The patients were referred to the clinic for primary treatment, or because another treatment modality had failed. Results: Of the respondents (n = 142, 78.4%), OSA had been diagnosed in 74%, while the MAD was applied for snoring to the remaining. Among all respondents, 78.4% had worn the MAD at least three nights per week. With the MAD in situ, sleep was felt significantly less disrupted (p < 0.001) and more restorative (p < 0.001), and snoring was markedly reduced (p < 0.001). Daytime tiredness was also markedly less frequent (p < 0.001). Conclusions: Treatment with a MAD improved perceived sleep quality and awoke alertness in mild and moderate OSA patients and in snorers. This study supports such treatment to be initiated and monitored in community dental care.展开更多
