title: Restless legs syndrome in multiple sclerosis.
abstract: Restless legs syndrome (RLS) is a sleep-related sensory-motor disorder characterized by an irresistible urge to move the legs accompanied by unpleasant sensations in the lower extremities. According to many recent studies patients with multiple sclerosis (MS) suffer frequently from symptoms of RLS. The prevalence of RLS in MS patients varies 13.3%-65.1%, which is higher than the prevalence of RLS in people of the same age in the general population. MS patients with RLS have higher scores in the Expanded Disability Status Scale compared to MS patients without RLS. Presence of RLS has a negative impact on sleep quality and fatigue of MS patients. Iron deficiency and chronic inflammation may be factors contributing to development of RLS in MS. The relationship between the course and treatment of MS and RLS requires further prospective studies.
