Objectif L’index d’apnees-hypopnees (IAH) determine par la polygraphie ventilatoire (PV) dans le SAS est sous-estime car la PV surestime la duree du sommeil et ne tient pas compte des hypopnees non desaturantes mais suivies d’un micro-eveil, d’ou des erreurs de determination de severite du SAHOS. Une etude anterieure a montre une difference de severite entre PV et polysomnographie (PSG) mais pas entre la PV associee a l’analyse automatique d’une voie EEG (PV + ) et PSG. Le but a ete d’etudier l’...

Objectif La somnolence diurne excessive (SDE) est un symptome frequent chez certains patients avec trouble deficit de l’attention hyperactivite (TDAH). L’objectif de cette etude est d’explorer chez des patients avec TDAH, l’evolution de la SDE en condition controlee, et d’evaluer si la SDE est liee a une alteration de la pression homeostatique du sommeil. Methodes Huit patients adultes avec TDAH et somnolents (sans traitement psychostimulants) et 7 sujets controles apparies en âge, sexe et chron...

A bidirectional detrimental relationship between sleep alteration and Alzheimer9s disease (AD) has been reported in cognitively normal older adults. Here, we tested whether a similar association could be detected in young adults, decades before typical AD symptom onset. We investigated associations between sleep endophenotypes and genome-wide Polygenic Risk Scores (PRS) for AD in 363 young men (22.1 +/- 2.7y) devoid of sleep and cognitive disorders. AD PRS was associated with higher slow wave en...

Sleep studies face new challenges in terms of data, objectives and metrics. This requires reappraising the adequacy of existing analysis methods, including scoring methods. Visual and automatic sleep scoring of healthy individuals were compared in terms of reliability (i.e., accuracy and stability) to find a scoring method capable of giving access to the actual data variability without adding exogenous variability. A first dataset (DS1, four recordings) scored by six experts plus an autoscoring ...

Abstract Cortical excitability depends on sleep-wake regulation, is central to cognition, and has been implicated in age-related cognitive decline. The dynamics of cortical excitability during prolonged wakefulness in aging are unknown, however. Here, we repeatedly probed cortical excitability of the frontal cortex using transcranial magnetic stimulation and electroencephalography in 13 young and 12 older healthy participants during sleep deprivation. Although overall cortical excitability did n...
