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’...

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 Study Objectives New challenges in sleep science require to describe fine grain phenomena or to deal with large datasets. Beside the human resource challenge of scoring huge datasets, the inter- and intra-expert variability may also reduce the sensitivity of such studies. Searching for a way to disentangle the variability induced by the scoring method from the actual variability in the data, visual and automatic sleep scorings of healthy individuals were examined. Methods A first datase...

Objective Recent studies suggest that sleep disorders or modifications of sleep stages or EEG waveform precede over the years the onset of clinical signs of pathological cognitive impairment (e.g., Alzheimer's disease). The aim of this study is to identify biomarkers based on EEG power values and spindles characteristics during sleep that occur early in mild cognitive impairment in older adults. Methods This study is a case-control cross-sectional study and one-year follow-up of the cases. Patie...

Objectif Notre objectif est d’identifier les marqueurs precoces bases sur les troubles du sommeil et/ou les deficits neuropsychologiques associes a l’apparition de plaintes isolees de memoire ou de troubles cognitifs legers lies au vieillissement. Methodes Des patients ayant des plaintes isolees de memoire ou des troubles cognitifs legers ont ete recrutes au sein de la cohorte MEMENTO suivie par le CMRR de Bordeaux, et apparies avec des temoins n’ayant aucune plainte mnesique. La macro-architect...
