This prospective observational study aims to determine the prevalence of malnutrition in patients with relapsing-remitting multiple sclerosis and to evaluate its association with disability. Nutritional status will be assessed using the Mini Nutritional Assessment-Short Form, and body composition will be evaluated with bioelectrical impedance analysis and anthropometric measurements. The study will also assess urinary incontinence, depression, and anger-related features, and compare the findings with those of healthy controls.
