Excessive daytime sleepiness has significant impact on neurological function, and has societal implications. Sleepiness is a common feature of many neurological conditions. A careful history will often reveal one of many common causes of excessive daytime sleepiness and suggest appropriate treatment. Neurophysiological testing can provide objective assessment. Behavioural management is an impor...

Abstract Background Wildland firefighting requires continuous attention while exposed to long working hours and sub-optimal sleep. These stressors may induce a state of cognitive fatigue, which poses risk worker safety due impaired judgment reduced awareness. Methods The current study employs within-subject, observational design examine the effect sleep schedule characteristics on variables rel...

UNLABELLED Falling asleep while driving accounts for a considerable proportion of vehicle accidents under monotonous driving conditions. Many of these accidents are related to work--for example, drivers of lorries, goods vehicles, and company cars. Time of day (circadian) effects are profound, with sleepiness being particularly evident during night shift work, and driving home afterwards. Circa...

BACKGROUND Although continuous positive airway pressure (CPAP) has become the standard of care in the treatment of obstructive sleep apnea (OSA), 2 systematic reviews have questioned its utility. Since the publication of these reviews, several randomized controlled trials have been reported. We, therefore, performed a meta-analysis to assess the effect of CPAP on subjective and objective sleepi...

Narcolepsy is an increasingly recognized sleep disorder characterized by excessive daytime sleepiness, symptoms of dissociated/abnormal rapid eye movement (REM) sleep, disrupted nocturnal sleep, and cataplexy. Although daytime sleepiness is the most disabling symptom, signi!cantly disrupted sleep at night results in a similar amount of sleep over 24 hours compared to controls. Many of the hallm...

Background: The non-image forming system, which conveys light information to circadian and sleep centers in the brain, is optimized to respond to short wavelengths of light (blue). Exposure to white light with reduced blue content can cause lower than expected circadian and sleep responses. These findings, however, come from controlled laboratory conditions that may not be entirely accurate whe...

introduction: epilepsy is a complex pervasive neurobehavioral and social condition accompanied by a wide range of comorbid conditions that can adversely affect the quality of life of patients. sleep complaints are common among patients with epilepsy. the aim of this study was to assess the prevalence of subjective sleep disturbances and its effects on sleep quality in epileptic patients.  metho...

We herein describe four cases of patients with Parkinson's disease who were treated with istradefylline (ISD) in the evening and had severe daytime sleepiness. The time to onset of sleepiness varied between 2 weeks to 3 months. All patients recovered after changing the timing of the ISD dosage from evening to morning. ISD is an A2A receptor antagonist with a caffeine-like arousal effect that ma...

A field-usable sleepiness tester could reduce sleepiness related accidents. 15 subjects' postural steadiness was measured with a Nintendo(®) Wii Fit balance board every hour for 24 h. Body sway was quantified with complexity index, CI, and the correlation between CI and alertness predicted by a three-process model of sleepiness was calculated. The CI group average was 8.9 ± 1.3 for alert and 7....
