Effects of Sleep Quality on Functional and Cognitive Outcomes in Multiple Sclerosis

The goal of this observational study is to investigate the effects of sleep quality on cognitive flexibility, physical activity level, body awareness, and reaction time in individuals with Multiple Sclerosis. The main question it aims to answer is: Does sleep quality influence cognitive flexibility, physical activity level, body awareness, and reaction time in individuals with Multiple Sclerosis? Researchers will compare individuals with good and poor sleep quality to determine whether differences in sleep quality result in variations in cognitive and physical performance outcomes. Participants will complete standardized assessments of sleep quality, cognitive flexibility, physical activity, and body awareness, and will perform a computer-based reaction time test. In addition, participants will wear a wearable activity tracker for 7 days to objectively measure physical activity levels.
