Introduction: Sleep disorder was one of major problems in elderly but had less attention. Excessive daytime sleepiness (EDS) was main symptom of sleep disorder that could cause cognitive impairment of the elderly, noted when someone falls asleep in an inappropriate time and place, and lowering their quality of life. The purpose of this study was to know the impact of EDS to cognitive function in elderly. Method: This study designed as a comparative cross sectional conducted from August 2010 until all samples collected; consist of 30 elderly with EDS and 30 without EDS. They were paired by age, sex, and education. Each group which was matched inclusion criteria underwent screening using Epworth Sleepiness Scale (ESS) and cognitive screening CERAD and Trail making Test-B. Result: Elderly with EDS had almost 7 times greater risk to have cognitive impairment compared to elderly without EDS. Cognitive impairment proportion in elderly with EDS was 80%, and non EDS 36,6% particularly in recent memory, delayed memory, recognition and executive function. Hypertension, DM, and dyslipidemia were not confounding factor in both groups. While younger age had protective effect to cognitive impairment in non EDS group. Degree of EDS and cognitive impairment was not related. Conclusion: Excessive daytime sleepiness influenced cognitive impairment in elderly. Comprehensive management was needed to prevent cognitive impairment in elderly with EDS.
