People with narcolepsy consistently report diminished memory function attributable to the disorder, however, objective evaluations of memory performance in this clinical group remain inconclusive. Previous evaluations of these subjective experiences have been primarily anecdotal with subjects required to provide global assessments of their memory function.(More)
The aim of the present study was to investigate whether eye lid movements (ELMs) were temporally related to the activity of other skeletal musculature and to proposed analogues of ponto-geniculo-occipital (PGO) waves during human sleep. Electroencephalogram (EEG), laryngeal-masseter electromyogram (EMG), electrooculgram (EOG), peri-orbital integrated(More)
Sleep inertia, the performance impairment that occurs immediately after awakening, has not been studied previously in relation to decision-making performance. Twelve subjects were monitored in the sleep laboratory for one night and twice awoken by a fire alarm (slow wave sleep, SWS and REM sleep). Decision making was measured over 10 3-min trials using the(More)
The prevalence of forced sex and its contribution to sleep difficulties among young Australian women aged 24-30 years (n=9,061) was examined using data from the 2003 Australian Longitudinal Study of Women's Health. The lifetime prevalence of reported forced sex was 8.7%. Significantly higher levels of recurrent sleep difficulties, prescription sleep(More)
This review brings together several different strands of research: (i) The sleep arousal literature pertaining to auditory arousal thresholds (AAT), (ii) studies on factors affecting responsiveness to auditory signals during sleep, (iii) literature on responsiveness to smoke detector alarms during sleep and (iv) research on fire fatality statistics and(More)
OBJECTIVES (i) To expose 'normal sleepers' to a 32-h sleep deprivation protocol and evaluate the impact of this deprivation on a complex performance task i.e. the paced auditory serial addition test (PASAT). (ii) To compare these sleep deprivation performance findings with historical data on the impact of sleepiness secondary to narcolepsy on PASAT(More)
The aim of this study was to determine whether wrist actigraphy could be used to assess the daytime effects of stimulant medication in the treatment of narcolepsy. Nine subjects with narcolepsy/cataplexy (medicated and unmedicated) were compared with matched control subjects. Data were collected over 4 days in the subjects' home. It was found that the(More)
How arousal thresholds vary with different sounds is a critical issue for emergency awakenings, especially as sleepers are dying in fires despite having a working smoke alarm. Previous research shows that the current high-pitched (3000+ Hz) smoke alarm signal is significantly less effective than an alternative signal, the 520 Hz square wave, in all(More)
