    Abstract:
    Sleep in elderly people shows progressive changes caused by general aging processes. Several alterations are described in medical literature: changes of sleep/wake rhythm and modifications both in sleep duration and in sleep architecture. The aim of our study was to evaluate sleep disturbances in elderly people, with and without cognitive impairment,through a sleep questionnaire. Our population included 1000 subjects, over 65 years of age, stratified by sex and age. The first 600 interviews were included in this report. All patients underwent a mini mental state examination (MMSE) and a questionnaire concerning excessive daytime sleepiness. In our total sample, we found a high prevalence of excessive daytime sleepiness, insomnia, nighttime awakenings, snoring, restlessness and periodic leg movements during sleep. Patients with cognitive dysfunctions showed less difficulty in falling asleep and fewer nighttime awakenings; they snored less frequently and were the only ones to present enuresis and to fall off the bed. Moreover, patients with cognitive impairment presented excessive daytime sleepiness with variable intensity and frequency. In conclusion, our results indicate significant differences in sleep disorders between healthy subjects and patients cognitively impaired. Besides, our subjective evaluation seems to be a useful method to perform an assessment of sleep disturbances in elderly people.
