    • Abstract:
      Background: This study investigates the relationship between sleep patterns and ischemic stroke beyond the predominant focus on obstructive sleep apnea. Through a systematic review of the existing literature, we aim to elucidate the connections between insomnia, sleep duration, cardiovascular factors, and ischemic stroke onset. Methods: We searched databases, including MEDLINE, SciELO, Scopus, and Science Direct, using an adapted PICO framework. Using a search strategy with MeSH words, keywords, and expressions related to insomnia and stroke, we included clinical trials and analytical observational epidemiological studies, comprising cohort, case–control, and cross-sectional studies. Results: Following the initial search, we identified 984 records, with 779 titles and abstracts screened for eligibility after removing duplicates. From these, 63 full-text articles, including 5 in the data synthesis, were reviewed. Our findings highlight a significant correlation between poor sleep quality, extreme sleep durations, and a heightened risk of ischemic stroke, along with established cardiovascular risk factors, such as hypertension, hyperlipidemia, obesity, and diabetes. Conclusions: This systematic review offers a comprehensive analysis of ischemic stroke prevalence and its association with cardiovascular factors, such as hypertension, hyperlipidemia, obesity, and diabetes. It suggests that poor sleep quality and extreme sleep durations, particularly long ones, are linked to a heightened risk of ischemic stroke. [ABSTRACT FROM AUTHOR]
