End of OSLER Test Sessions in XXXX do not Correspond to True Sleep Onset: Results from an Exploratory Study.

@entity1 @entity25 @entity191
The aim of the present study was to evaluate the correlation between the end of an Oxford sleep resistance (OSLER) test session and a neurophysiological marker of sleep onset in @entity191 ( @entity191 ) @entity1 . Single center study was conducted in @entity191 @entity1 with excessive @entity25 [ @entity25 scale (ESS) >9]. The OSLER test was conducted with a concomitant electroencephalography (EEG), electromyography (mentalis), right and left electroculogram, and video monitoring. Neurophysiological (NP) sleep onset was defined according to AASM criteria (2005). Five @entity191 @entity1 with mean ESS of 14 (10-16) were included. OSLER test duration was shorter than 40   min in all @entity1 (mean duration 20   min and 39   s). No @entity1 fulfilled neurophysiological criteria to sleep onset at the time of OSLER test termination. In 13 OSLER sessions that ended before 40   min, eight had microsleeps in the last 30   s before the end of the test. NP monitoring showed signs of @entity25 in all @entity1 . In @entity191 @entity1 , the early termination of an OSLER test session may not correspond to NP criteria of sleep onset. However, in all @entity191 @entity1 with abnormal OSLER results, there were EEG signs of @entity25 , which do not exclude the potential utility of OSLER test to evaluate the risk of falling asleep.
