To investigate the characteristics and subjective quality of sleep, the use of hypnotics and their correlates in an urban elderly population, a structured interview was administered to a stratified random sample of 600 elderly subjects in five age groups. Interrupted sleep and napping were common; nonetheless, 88% of the subjects considered their sleep at least satisfactory. According to specific criteria, 17% were good, 72% moderate and 11% poor sleepers. Habitual insomnia was reported by 12% of the subjects. Quality of sleep did not differ between age groups or genders. Hypnotics were habitually used by 8% of the men and 25% of the women. Consumption increased with age in both sexes, and 77% of the hypnotics were benzodiazepines. In multivariate regression analyses, insomnia and habitual use of hypnotics were associated with poor health, but only the latter with age and gender. As a conclusion, most of the subjects considered their sleep satisfactory, and aging itself did not seem to have an effect on the quality of sleep. The use of hypnotics was common, more prevalent in women and increased with age. Aging and poor health were independently associated with the use of hypnotics, but not with poor quality of sleep or insomnia.

Fatigue is common in multiple sclerosis (MS) and is an important cause of disability. However, the cause of fatigue is poorly understood. This study aimed to describe the frequency and pattern of sleep disturbance in a group of outpatients with MS, and to investigate the relationship between sleep disturbance and fatigue. Sixty outpatients with MS completed the Fatigue Severity Scale (FSS) and the Epworth Sleepiness Scale and kept a sleep diary for seven days. Fatigue and excessive daytime sleepiness were common in this group of patients (64 and 32%). Sleep problems on at least two nights per week occurred frequently, including initial insomnia in 42%, middle insomnia in 53% and terminal insomnia in 58%. The reasons cited for different types of insomnia varied, with anxiety and pain/discomfort being the commonest causes of initial insomnia and nocturia the commonest cause of middle insomnia. Middle insomnia was significantly correlated with daytime fatigue, a relationship that remained after controlling for disability. Sleep disturbance is common in MS and is associated with treatable symptoms, including pain and nocturia. Sleep disturbance may be an important factor contributing to fatigue in patients with MS.
