Previous attempts to investigate the relationship between sleepiness and performance for subjects with narcolepsy have been limited by both the ability of narcoleptic subjects to contain their sleepiness for brief testing periods and the potential lack of sensitivity of routine performance tasks to sleepiness induced changes. The present study developed a(More)
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)
OBJECTIVES The study sought to (i) assess psychosocial adjustment, disruption due to symptoms, and medication problems in narcolepsy, (ii) determine how these variables changed with gender, age and medication status, and (iii) compare narcolepsy adjustment with three other illness groups. BACKGROUND Psychosocial adjustment to an illness can be(More)
Ageing is associated with a decrease in the quality of night-time sleep with 30% of aged persons experiencing chronic insomnia. Treatment of insomnia typically involves the use of hypnotic medications and these have been associated with a range of negative outcomes in this population cohort. The development of age-related insomnia has been linked, in part,(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)
Childhood sexual abuse (CSA) is the form of sexual victimization most correlated with sexual dysfunction in adulthood (Atkeson, Calhoun, Resick, & Ellis, 1994; Sarwer & Durlak, 1996; Laumann, Paik, & Rosen, 1999). The goal of this study was to address the sexual ramifications of unresolved CSA and consider the effectiveness of vasoactive pharmacotherapy,(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)
Eighteen patients with idiopathic hypersomnia (IH) were compared with 50 patients with the narcoleptic syndrome of cataplexy and daytime sleepiness (NLS) using self report questionnaires and a diary of sleep/wake patterns. The IH group reported more consolidated nocturnal sleep, a lower propensity to nap, greater refreshment after naps, and a greater(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)
