Relationship of Epileptic Seizures to Sleep Stage and Sleep Depth [PDF]
Sleep, 2002 Interictal epileptiform discharges (IEDs) are facilitated by NREM stages 3 and 4 sleep and as sleep is deepening. To determine whether sleep influences seizures in a similar way to IEDs, we examined seizure rates in various stages of sleep in epilepsy patients undergoing overnight video-EEG-polysomnography (VPSG).Cross-sectional study.Neurology ...

U-Sleep: resilient high-frequency sleep staging [PDF]
npj Digital Medicine, 2021 AbstractSleep disorders affect a large portion of the global population and are strong predictors of morbidity and all-cause mortality. Sleep staging segments a period of sleep into a sequence of phases providing the basis for most clinical decisions in sleep medicine.

Sleep CLIP: A Multimodal Sleep Staging Model Based on Sleep Signals and Sleep Staging Labels
Sensors, 2023 Since the release of the contrastive language-image pre-training (CLIP) model designed by the OpenAI team, it has been applied in several fields owing to its high accuracy. Sleep staging is an important method of diagnosing sleep disorders, and the completion of sleep staging tasks with high accuracy has always remained the main goal of sleep staging ...

Sleep Position and Sleep Stages: Evidence of Their Independence [PDF]
Sleep, 1998 Recently we conducted a first ontogenetic study of sleep positions in the human, which involved five groups of 10 subjects (5 males, 5 females) from each of the following age categories: 3-5 years, 8-12 years, 18-24 years, 35-45 years, 65-80 years. They slept for 4 consecutive nights in the laboratory. Sleep positions were recorded during 2 nights with

A Taxonomic Analysis of Sleep Stages [PDF]
Sleep, 2006 To study the structure of human sleep at the level of sleep stages. We applied taxonomic statistics to detect significant configurations (types) of different physiologic variables and their relationship to sleep stages. DESIGN AND STATISTICS: Polygraphic sleep recordings from 32 subjects (normal sleepers as well as patients with insomnia, sleep apnea ...

The Future of Sleep Staging, Revisited
Nature and Science of Sleep, 2023 In 1996, I published a paper entitled "The Future of Sleep Staging". At this time, paper and ink records were the standard way of recording sleep records. Computerised systems had only recently become commercially available. The original article was a response to those initial computer-based systems, pointing out the potential limitations of the ...

The Effects of Sleep Posture and Sleep Stage on Apnea Frequency [PDF]
Sleep, 1991 The Apnea Plus Hypopnea Index (A + HI) of 60 male positional sleep apneics was analyzed by sleep stage to determine if positional differences are limited to NREM sleep. Differences in apnea severity by sleep position were found to persist in REM sleep and to be of equal extent to those differences found in NREM sleep, despite the fact that there is ...

Sleep Stage Determines the ExpressionPattern of Sleep Apneas
Internal Medicine, 2007 We report on an obese man with sleep stage-dependent apnea. His type of apnea was predominantly central during non-rapid eye movement (NREM) sleep, while it was obstructive during rapid eye movement (REM) sleep. We found significantly more and more severe apneas during REM sleep compared to NREM sleep.

A Convolutional Network for the Classification of Sleep Stages [PDF]
XoveTIC Congress 2018, 2018 Trátase dun resumo estendido da ponencia [Abstract] The classification of sleep stages is a crucial task in the context of sleep medicine. It involves the analysis of multiple signals thus being tedious and complex. Even for a trained physician scoring a whole night sleep study can take several hours.

Sleep stage dynamics in young patients with sleep bruxism [PDF]
Sleep, 2019 AbstractStudy ObjectivesWe hypothesized that sleep stage dynamics are different in patients with sleep bruxism (SB) and that these changes are associated with the occurrence of rhythmic masticatory muscle activity (RMMA).MethodsFifteen healthy controls and 15 patients with SB underwent overnight polysomnography.
