EFFECT OF FAMILY HISTORY OF DEMENTIA AND SELF-REPORT OF SLEEP QUALITY ON COGNITIVE PERFORMANCE IN HEALTHY OLDER ADULTS
PublisherThe University of Arizona.
AbstractThis study sought to identify the effect of family history of dementia and sleep quality on cognitive performance in a cohort of healthy older adults (n=89). Cognitive abilities were assessed using a comprehensive neuropsychological battery. The tested domains included memory, executive function, visuospatial abilities, motor function, processing speed, and language abilities. Subject family history was obtained by self report, and sleep quality was quantified using the Pittsburgh Sleep Quality Index (PSQI). Participants were divided into four groups by family history of dementia and sleep quality. Results indicated no significance effects for memory or executive function, but effects were found in visuospatial and motor tasks. It was observed that subjects without family history of dementia and good quality sleep had better performance on visuospatial tasks, supporting the notion that these factors may have protective functions in cognitive decline.
