Background: Sleep disorders are common in multiple sclerosis (MS) patients, negatively impacting them physically and mentally. Few studies measured the correlation between sleep quality and daytime sleepiness in RRMS patients. Objective: To assess the relationship between sleep quality and excessive daytime sleepiness in patients with relapsing-remitting multiple sclerosis. Methods: Forty patients with relapsing-remitting multiple sclerosis (RRMS) were evaluated using Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) to measure sleep quality and excessive daytime sleepiness, respectively. The patients were of both sexes, aged between 20 and 40 years, with an EDSS of less than four and no relapses for the previous three months. All participants had sufficient cognitive abilities with a score greater than 24, according to the Miniature Mental State Examination Scale (MMSE). Results: There was no significant correlation between the Epworth score for drowsiness (ESS) and Pittsburgh sleep quality index (PSQI) in patients with RRMS, according to this study. Conclusion: This study shows no correlation between the Epworth Sleepiness scale (ESS) and Pittsburgh sleep quality index (PSQI) in patients with RRMS, indicating that poor night sleep quality is not necessarily compensated with daytime sleepiness. In terms of clinical application, this study emphasizes the importance of assessing the different aspects of sleep during night and daytime in RRMS patients.
