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)
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)
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)
Multiple system atrophy is an atypical parkinsonism characterized by severe motor disabilities that are poorly levodopa responsive. Most patients develop rapid eye movement sleep behaviour disorder. Because parkinsonism is absent during rapid eye movement sleep behaviour disorder in patients with Parkinson's disease, we studied the movements of patients(More)
Obstructive sleep apnea syndrome (OSAS) is a sleep-related breathing disorder characterized by repetitive episodes of airflow cessation, resulting in brief arousals and intermittent hypoxemia. OSAS is associated with a number of adverse health consequences, and cognitive difficulties. The overall pattern of cognitive impairment in OSAS is complex, and(More)
Patients with obstructive sleep apnoea syndrome exhibit memory deficit. The present study looked at whether this deficit is related to impaired memory monitoring and/or memory control. Here 25 patients and 26 healthy controls performed a paired-associate learning task. After participants had made a judgement of learning for each pair and performed an(More)
We assessed decision making in 20 patients newly diagnosed with obstructive sleep apnoea (OSA) and 20 healthy controls with the Iowa Gambling Task (IGT), which evaluates the ability to learn to sacrifice immediate rewards in favour of long-term gains. A standard neuropsychological battery was administered. Switching scores tended to be lower in patients.(More)
This study assessed metamemory and its role in actual episodic memory performance in 26 patients with obstructive sleep apnea syndrome and 27 healthy controls. Metamemory knowledge and memory beliefs were assessed using the Metamemory Inventory in Adulthood. Episodic memory performance was investigated with the Remember/Know paradigm. Subjective sleepiness(More)
