Poor Sleep Quality Related to Impaired Cognitive Function Following Stroke: A Comparative Cross-Sectional Study

Sleep deprivation is a common concern among stroke patients. There was a connection between sleep deprivation and poor cognitive function. Few studies, however, have compared sleep and cognitive variations in older adults with and without stroke, as well as explored the relationship between sleep quality and cognitive function. The objective of this study was to explore the quality and feature of sleep between patients with and without a stroke. To assess the association between sleep quality and cognitive dysfunction in older adults. A cross-sectional analysis was carried out. 156 participants completed this research. The study was carried out in 90 stroke patients and 66 of non-stroke patients. The patient was given a sleep quality questionnaire and took a cognitive test. In addition, a multivariate linear regression statistical analysis was used to determine the relationship between two variables. The global mean PSQI in patients with stroke was 7.12±3.96 versus 4.98±2.86, respectively, higher than the non-stroke group. Around 56.7 percent of stroke patients complained of poor sleep quality. Stroke patients scored lower than those who did not get a stroke on the memory and executive function test. Sleep quality affects memory by 28.6 percent. Poor sleep quality was strongly associated with memory dysfunction in stroke patients. To prevent patients with stroke from experiencing cognitive loss, health care providers should develop effective interventions to improve sleep quality.
