A Demographic and Polysomnographic Investigation of Fatigue and Sleep Disorders in Patients with Multiple Sclerosis

Objective: To investigate fatigue and sleep disorders based on demographic, clinical and polysomnographic data and show their effects on the quality of life in multiple sclerosis (MS) patients. Materials and Methods: Thirty MS patients were enrolled in the study depending on the results of the polysomnography (PSG), Fatigue Severity scale, Epworth Sleepiness scale (ESS), Pittsburgh Sleep Quality Iindex, Beck Depression and Anxiety inventories.

PSG data revealed that stage N2 sleep duration of those who did not use interferon was significantly longer than those who used it (p
