Subjective and objective sleep quality in elderly individuals: The role of psychogeriatric evaluation.

Aging affects sleep and sleep problems are common in older individuals. However, the relationship between objective and subjective tools for analysing sleep and psycho-geriatric variables have not been tested in institutionalised older individuals. This work analyses sleep quality by using actigraphy as an objective tool and validates the Athens and Oviedo sleep questionnaires in octogenarian elderly individuals as subjective scales of sleep perception.

Sleep Alterations in Non-demented Older Individuals: The Role of Cortisol.

Background: Sleep alterations can impair quality of life and contribute to disease progression but they, and their features and contributing factors, are rarely analysed in institutionalised older individuals. In this study, we investigated sleep alterations, the factors involved, and the role of cortisol in sleep-related problems in institutionalised individuals.

Methods: We conducted a descriptive cross-sectional study in participants living in nursing homes in Valencia (Spain); sleep alterations were determined based on two validated tools: the Athens insomnia scale and Oviedo sleep questionnaire.
