Recognition memory performance reflects two distinct memory processes: a conscious process of recollection, which allows remembering specific details of a previous event, and familiarity, which emerges in the absence of any conscious information about the context in which the event occurred. Slow wave sleep (SWS) and rapid eye movement (REM) sleep are(More)
BACKGROUND AND PURPOSE Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for stroke. Impairment of cerebral autoregulation may play a potential role in the pre-disposition to stroke of OSAS patients. In this study, we aimed to assess dynamic cerebral autoregulation (DCA) during wakefulness in OSAS patients and a group of matched(More)
Between 1990 and 1995, 369 patients were investigated for obstructive sleep apnea syndrome (OSAS) by polysomnography. Among them, 248 patients with a mean Apnea-Hyponea index (AHI) of 37.7 per hour were treated by nasal continuous positive airway pressure (n-CPAP). Mean follow up was 39.5 +/- 20.4 months. In this group, 23 patients (9.2%) refused nCPAP(More)
BACKGROUND Sleep disorders differ widely in the heterogeneous older adult population. Older adults can be classified into three groups based upon their overall level of disability: healthy, dependent, and frail. Frailty is an emerging concept that denotes older persons at increased risk for poor outcomes. OBJECTIVE The aim of this consensus review is to(More)
This study evaluated episodic memory, with an emphasis on the recollection of spatial and temporal contexts, in 28 patients suffering from obstructive sleep apnea syndrome and 29 healthy controls. Recollection was assessed by means of the R/K paradigm and the process-dissociation procedure. Attentional abilities were also evaluated. A polysomnographic(More)
Nocturnal oximetry can show nocturnal oxygen desaturation. This examination was proposed as an investigation for the early detection of the sleep apnoea syndrome (SAS). We have compared the results of nocturnal oximetry and polysomnography in 329 consecutive patients seen in the department of thoracic medicine for the early detection of the SAS between June(More)
INTRODUCTION Continuous positive airway pressure (CPAP) is ineffective in some patients with obstructive sleep apnoea syndrome (OSAS) and some patients do not tolerate it. This study evaluated the outcomes of maxillo-mandibular advancement in OSAS patients without morbid obesity or severe maxillo-mandibular deformity who had first been treated with CPAP for(More)
