Sleep Disturbances at 3 Months after Cerebral Infarction

摘要

Background: Post-stroke sleep disturbances (PSSD) are common and associated with various adverse outcomes. However, PSSD in the sub-acute stages of stroke have been scarcely studied. We aimed to evaluate the characteristics of and the factors related to PSSD in stroke patients 3 months post stroke. Methods: A total of 199 patients were evaluated for PSSD at 3 months after stroke. The qualities of nighttime sleep and excessive daytime sleepiness (EDS) were assessed using the Verran Snyder-Halpern sleep scale and Epworth Sleepiness Scale, respectively. Presence of motor dysfunction and post-stroke pain, post-stroke depression, fatigue and social support were evaluated. Results: Eighty-eight patients (44.2) had poor quality of nighttime sleep. Twenty-eight patients (14.4) reported EDS. Poor quality of nighttime sleep was independently associated with depression (p = 0.044) and EDS (p = 0.041) whereas fatigue (p < 0.001) and poor nighttime sleep (p = 0.045) were independently associated with EDS. Post-stroke pain and social support showed no association with PSSD. Conclusions: We found that the occurrence of PSSD 3 months after stroke is common. Although causality remained to be determined, depression and nighttime sleep disturbances were related, whereas fatigue and nighttime sleep disturbances were related to EDS. (C) 2016 S.
