STUDY OBJECTIVES To examine polysomnographic parameters and sleep diary data, as well as the prevalence of sleep apnea and periodic limb movement disorder (PLMD) in older chronic users of zopiclone compared with aged-matched drug-free patients with insomnia and good sleepers. METHODS Polysomnographic data were collected at a university-based outpatient clinic for adults and elderly. Seventeen...

OBJECTIVE Although stress is often presumed to cause sleep disturbances, little research has documented the role of stressful life events in primary insomnia. The present study examined the relationship of stress and coping skills, and the potential mediating role of presleep arousal, to sleep patterns in good sleepers and insomnia sufferers. METHODS The sample was composed of 67 participants...

BACKGROUND Sleep disturbance is a complex health problem in ageing global populations decreasing quality of life among many older people. Geographic, cultural, and ethnic differences in sleep patterns have been documented within and between Western and Asian populations. The aim of this study was to explore sleep problems among Hong Kong seniors by examining the prevalence of poor sleep quality...

STUDY OBJECTIVES Morphometric analysis of magnetic resonance imaging brain scans was used to investigate possible neuroanatomic differences between patients with primary insomnia compared to good sleepers. DESIGN MRI images (1.5 Tesla) of the brain were obtained from insomnia patients and good sleepers. MRI scans were analyzed bilaterally by manual morphometry for different brain areas includ...

BACKGROUND Clinical and pre-clinical data agree that opioids disrupt sleep architecture. Recently, remifentanil has been suggested to cause possible long-term disturbances of sleep quality. This randomized controlled clinical trial was designed to substantiate or refute a possible long-term effect of remifentanil on the quality of sleep. METHODS One hundred patients undergoing elective surger...

STUDY OBJECTIVES To evaluate the psychometric properties and clinical significance of a new scale for measuring daytime fatigue associated with insomnia: The Flinders Fatigue Scale (FFS). METHODS The 7-item FFS was used in two separate studies. Study 1 was an on-line validation study involving 1093 volunteers (mean [SD] age = 38.6 [14.7] y, 626 poor sleepers, 467 good sleepers) in a cross-sec...
