The growing embrace of patient-centered outcomes research (PCOR) in sleep medicine is a significant step forward for the field. In engaging and incorporating the unique perspectives of people with sleep disorders, PCOR enhances the relevance of findings and facilitates the uptake of research into practice. While centering research design around what matters most to people with sleep disorders is critical, research communication must be similarly people-centered. One approach is using "people-centered language" in both professional and public communications...

Study Objectives: Obstructive sleep apnea (OSA) is a common sleep disorder. Actually, literature lacks studies examining sleep, cognition, and Alzheimer's Disease (AD) cerebrospinal-fluid biomarkers in OSA patients. Therefore, we firstly studied cognitive performances, polysomnographic sleep, and CSF β-amyloid, tau proteins and lactate levels in patients affected by subjective cognitive impairment (SCI) divided in three groups: OSA patients (showing an Apnea-Hypopnea Index - AHI ≥15/h), controls (showing an AHI<15/h), and patients treating OSA by continuous positive airway pressure (CPAP)...

Obstructive Sleep Apnea (OSA) is a sleep disorder highly prevalent in the general population. Cardiorespiratory Phase Synchronization (CRPS) is a form of non-linear interaction between respiratory and cardiovascular systems that was found to be reduced in severe OSA patients. The Hilbert Transform (HT) method was the recommended choice for estimating the respiratory phase in CRPS studies. But we have noticed that HT provides a phase that is aligned to the transition between the exhalation and the inhalation parts of different breathing cycles, instead of being aligned to the breathing onsets...

This paper presents a method for the detection of wakeful state, rapid eye movement sleep (REM), light sleep (N1&N2) and deep sleep (N3&N4) based on cardiorespiratory parameters. Experiments were conducted with data of 625 subjects without sleep-disordered breathing selected from the SHHS dataset. Compared to previous studies, our method considers results of neighboring epochs classification and epoch position over record time. The method demonstrates Cohen's kappa of 0.57 ± 0.13 and the accuracy of 71.4 ± 8...

Polygoni Multiflori Caulis is a traditional Chinese medicine that has been used for a long time to treat sleep disorders. However, the multiple chemical composition analysis has not been reported. In this study, a simple, rapid and effective ultra high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry method was established to characterize the components of Polygoni Multiflori Caulis. In addition, a chemical comparative analysis was performed with Polygoni Multiflori Radix, another traditional Chinese medicine from the same plant, through multivariate statistical analysis and semi-quantitative analysis to screen the difference in chemical ingredients between these two herbal medicines from same medicinal plant...

The role of dopamine in sleep-wake regulation is associated as a wakefulness-promoting agent. For the clinical treatment of excessive daytime sleepiness, drugs have been commonly used to increase dopamine release. However, sleep disorders or lack of sleep is related to several dopamine-related disorders. The effects of dopaminergic agents, nevertheless, are mediated by two families of dopamine receptors, D1 and D2-like receptors; the first family increases adenylyl cyclase activity and the second inhibits adenylyl cyclase...

We used a remotely monitored non-contact biosensor (SleepMinder™) to measure breathing during sleep (SDB) in a prospective study of 91 patients with stable class II to IV heart failure (HF). The device algorithm measures a surrogate of the traditional apnoea/hypopnoea index (AHI) measured in polysomnographic sleep studies. Data was transmitted daily to a central monitoring centre and analysed in consecutive 2-week blocks. A total of 37 465 nights over 3-24 months was analysed. An AHI of >15/h was considered clinically significant...

BACKGROUND: Both Parkinson's disease (PD) and multiple system atrophy (MSA) have associated sleep disorders related to the underlying neurodegenerative pathology. Clinically, MSA with predominant parkinsonism (MSA-P) resembles PD in the manifestation of prominent parkinsonism. Whether the amount of rapid eye movement (REM) sleep without atonia could be a potential marker for differentiating MSA-P from PD has not been thoroughly investigated. This study aimed to examine whether sleep parameters could provide a method for differentiating MSA-P from PD...

Sleep spindles and K-complexes are among the most prominent micro-events observed in electroencephalographic (EEG) recordings during sleep. These EEG microstructures are thought to be hallmarks of sleep-related cognitive processes. Although tedious and time-consuming, their identification and quantification is important for sleep studies in both healthy subjects and patients with sleep disorders. Therefore, procedures for automatic detection of spindles and K-complexes could provide valuable assistance to researchers and clinicians in the field...

Elissaios Karageorgiou, Keith A Vossel
This perspective binds emerging evidence on the bidirectional relationship between Alzheimer's disease (AD) and sleep disorders through a model of brain rhythm attractor breakdown. This approach explains behavioral-cognitive changes in AD across the sleep-wake cycle and supports a causal association between early brainstem tau pathology and subsequent cortical amyloid-β accumulation. Specifically, early tau dysregulation within brainstem-hypothalamic nuclei leads to breakdown of sleep-wake attractor networks, with patients displaying an attenuated range of behavioral and electrophysiological activity patterns, a "twilight zone" of constant activity between deep rest and full alertness...
