Filter by:The Epworth Sleepiness Scale (ESS) is undoubtedly the most commonly used tool in daily clinical practice to assess daytime sleepiness in patients of all ages by means of a self-administered questionnaire. In elderly subjects, the clinician is often confronted with difficulties in accurately estimating the ESS score and measuring subjective daytime sleepiness. Indeed, according to Onen et al, the ESS tends to underestimate the prevalence of sleep disorders in the geriatric population, mainly due to non-response to problematic items, namely: - Item 3: Sitting, inactive in a public place (cinema, theater, meeting) - Item 8: In a car that has been stopped for a few minutes. In order to overcome this problem, Janine Gronewold's German team has developed and begun work on the validation of an alternative version of the ESS, the ESS-ALT, adapted to the population of interest, in German. The aim of the present work is to adapt the ESS-ALT in French, then to study its correlation with sleep data recorded by nocturnal polysomnography, and among the secondary objectives, to correlate it with sleep latency during iterative sleep latency tests, in order to propose to the clinician a simple, reproducible tool, allowing to measure daytime sleepiness in elderly subjects.
Excessive daytime sleepiness which still remains after an effective treatment with nocturnal ventilotherapy or with other specific treatments (positional therapy, oro-mandibular devices) in patients with obstructive sleep apnea syndrome has a prevalence of 55% of treated cases, representing a notable theme of clinical and research interest. In recent years there have been several studies on the use of wakefulness-promoting drugs generally prescribed in patients with narcolepsy, in this disorder with promising results. Right in consideration of the forthcoming approval of these drugs, it is important to find biomarkers able to predict which patients will develop daytime sleepiness resistant to ventilatory treatment. Several studies have highlighted the association between obstructive sleep apnea syndrome and the increase of cerebral amyloid beta deposits, concluding that apnoic disorder can be considered a risk factor for the development of cognitive impairment and Alzheimer';s disease. In this scenario, it would be useful to identify biological markers able to underline which clinical phenotypes of sleep apnea syndrome are more associated with residual excessive daytime sleepiness and/or cognitive impairment. In recent years several kits for the assay of biomarkers of neurodegeneration have been developed not only in CSF, but also in human serum. Among them, the most important are light chain neurofilaments (NFL), amyloid isoforms 40 and 42 (Ab40 and Ab42). Other biomarkers found in neurodegenerative diseases associated with excessive daytime sleepiness are orexin A (OXA) and histamine (HA). In this view, the aim of this study is to evaluate the role of biomarkers of neurodegeneration in characterizing disease severity and response to treatment of obstructive sleep apnea syndrome with residual excessive daytime sleepiness.
This research aims to develop a better understanding and clinical knowledge of the effects of a plant-based diet on postprandial sleepiness.
Estimating that people sleep on average up to two hours less over the last decades, sleepiness and fatigue need to be considered as significant societal problems of the modern world. Jurisdiction is precise on how to deal with overtired offenders since they were not allowed to use machines or vehicles in the first place, similar to drunk individuals or consumers of illicit drugs. In contrast to alcohol or illicit drug use, however, there are no quick roadside or workplace tests as objective (analytical) biomarkers for sleepiness. Investigators hypothesize that increasing sleep drive or impaired wakefulness can be assessed by qualitative or quantitative fluctuations of certain metabolites in biological specimens, e.g., accumulation or decrease of endogenous substances related to sleep debt. Thus, this sleep study provides the necessary biological samples of either sleep-deprived, sleep-restricted, or control subjects, which are then analysed for appropriate metabolite biomarkers utilizing an untargeted metabolomics approach. In addition to established impairment tests, a state of the art driving simulator will be employed to objectively measure driving performance under all study conditions. Participants will also rate their subjective sleepiness using validated questionnaires.
Poor sleep is closely related to circadian misalignment; shift workers often experience shift work disorder characterized by excessive sleepiness and recurrent shift work schedules-associated insomnia. This study aims to examine the effects of a program of chronobiology-guided lifestyle interventions (CGLI) on insomnia severity, cognitive performance (psychomotor vigilance and processing speed), and sleepiness in female nurses undertaking rotating-shift work.
The purpose of this study is to examine the effect of long-term carbohydrate periodization protocols on sleep architecture, sleep quality, daytime sleepiness, physical performance, body composition, gut microbiome, and miRNA in healthy trained individuals.
The primary objective of this study is to assess the long-term safety and effectiveness of pitolisant in patients with idiopathic hypersomnia (IH) who completed the Double-Blind Randomized Withdrawal Phase of study HBS-101-CL-010.
As children pass through puberty the timing of their sleep-wake cycle shifts and they experience a strong urge to stay up and awaken late. High school typically starts early in the morning and a significant percentage of normal adolescents arrive at school each day with an insufficient amount of sleep, which can take a substantial toll on their academic performance. As the primary reason for insufficient sleep is a naturally occurring propensity to stay up later in the evening it seems plausible that bright light treatment (BLT) at the appropriate time may phase advance biological clocks and potentially reverse this problem. Hence, the investigators are testing the hypothesis that consistent morning use of a light emitting diode (LED) BLT device (LiteBook Edge™) by healthy adolescents will shift the phase of their sleep wake cycle and enable them to receive an increased amount of sleep during the school week and perform better on tests of attention and academic performance and evidence signs of improved alertness. Alternatively, BLT could potentially enhance alertness through other mechanisms, such as a direct arousing effect, without exerting a discernible effect on circadian phase or sleep duration.
The objective of this study is to demonstrate the efficacy and safety of pitolisant versus placebo during 12 weeks of the Double Blind period, to treat the Excessive Daytime Sleepiness (EDS) in patients with Obstructive Sleep Apnea (OSA) not tolerating or refusing the nasal Continuous Positive Airway Pressure (nCPAP) therapy or treated by nCPAP but still complaining of EDS.
Excessive diurnal sleepiness is characterized by an incapacity to stay awake, in favour of sleep occurrence. This sleepiness might be secondary to a sleep disorder; when it is not the case, it is primary hypersomnia (including narcolepsy and idiopathic hypersomnia). To date, objective measures of sleepiness can only be achieved in laboratory. Subjective techniques as scales and questionnaires are highly sensitive to inter-individual differences and cannot constitute a reliable diagnosis tool of sleepiness. Recent studies suggested that some salivary biomarkers are sensitive to sleep characteristics and thus, may allow the objective and easy evaluation of sleepiness. The objective of the study is to explore the usability of salivary biomarkers (a-amylase and oxalate) as a new non-invasive technique to evaluate sleepiness and to diagnose primary hypersomnia in children. The hypothesis of this study is that there will be a modification of salivary biomarkers concentrations with the variations of diurnal sleepiness.
