Aircrew were studied before and after flying one of two routes: San Francisco (SFO) to London (LHR) or SFO to Tokyo (NRT). After an adaptation night, sleep and daytime sleepiness were objectively measured in SFO and during the first layover (L/O) of the target trip. Baseline sleep was slightly shorter than normally reported for similar age subjects and, for several reasons, is not an ideal basi...

OBJECTIVE To compare the effects of 800 mg of valerian with a placebo on sleep quality and symptom severity in people with restless legs syndrome (RLS). METHODS A prospective, triple-blinded, randomized, placebo-controlled, parallel design was used to compare the efficacy of valerian with placebo on sleep quality and symptom severity in patients with RLS. Thirty-seven participants were random...

Poor sleep quality and daytime somnolence is reported to be associated with cardiovascular events, road traffic accident, poor academic performance and psychological distress. Some studies documented that it is prevalent in most populations but its frequency among medical students has not been documented in Malaysia. This is a self-administered questionnaire survey of medical students from Inte...

OBJECTIVES The aim of this study is to assess the sleep quality and sleep disorders (prevalence of obstructive sleep apnea and sleepiness) among occupational drivers in Iran and to determine which demographic factors and occupational habits are linked to road traffic accidents. MATERIAL AND METHODS In this analytic cross-sectional study 556 occupational road drivers from Shahroud city (in the...

OBJECTIVES To assess the therapeutic efficacy of modafinil in the treatment of increased daytime sleepiness in patients with Parkinson's disease (PD). DESIGN Double-blind, randomized, placebo-controlled crossover study with two 2-week treatment blocks, separated by a 2-week washout phase. SETTING Tertiary Parkinson's disease care center and sleep laboratory at university hospital neurology ...

BACKGROUND AND PURPOSE Obstructive sleep apnea (OSA) is seldom considered in the diagnostic investigation in the poststroke period although it is a stroke risk factor and has adverse prognostic implications after stroke. One reason might be that widely used clinical criteria for detection of OSA in the general community are not applicable in patients with stroke. We hypothesized that patients w...

BACKGROUND Many patients on maintenance dialysis experience significant sleepiness and fatigue. However, the influence of the hemodialysis (HD) day and circadian rhythms on patients' symptoms have not been well characterized. We sought to use ecological momentary assessment to evaluate day-to-day and diurnal variability of fatigue, sleepiness, exhaustion and related symptoms in thrice-weekly ma...

Sleepiness is a major risk factor in traffic- and occupational accidents. While sleepiness is a persistent concern, there is no convenient test to monitor impending levels of sleepiness. We show that force platform posturographic balance testing addresses this need because it estimates time awake (TA) accurately and precisely. Testing the TA is appropriate because TA drives the sleep homeostati...

BACKGROUND Night-to-night variability in sleep of children with attention deficit hyperactivity disorder (ADHD) may be a mediator of behavioral phenotype. We examined the potential association between alertness, sleep, and eating behaviors in children with ADHD and comorbid problems. METHODS Sleep was monitored by actigraphy for 7 days. Questionnaires were used to assess sleep complaints, hab...

Sleep is typically initiated on the declining portion of the circadian rhythm of core body temperature (CBT) when its rate of change, and body heat loss, is maximal. Distal vasodilatation plays a primary role in the circadian regulation of body heat loss and is strongly associated with sleepiness and sleep induction. In contrast, sleep (i.e. non-REM sleep and slow-wave activity, SWA) has no or ...
