Time to REST: epidemiology and burden.
Restless legs syndrome (RLS) is a neurological disorder characterized by a compelling urge to move, accompanied by disturbing sensations within the legs. It is now recognized that RLS is a common condition that has a substantial impact on sleep, daily activities and quality of life. Recent data from the REST (RLS Epidemiology, Symptoms, and Treatment) general population study show that symptoms of RLS are present in approximately 7% of the general population, and that 2-3% experience moderate or severe symptoms at least twice a week. Amongst this RLS cohort, approximately 88% reported sensory disturbances and 76% reported sleep-related symptoms. These symptoms had a marked effect on everyday life, with up to 50% of the RLS cohort reporting disruption of everyday activities or personal relationships. Sleep disturbances in turn lead to impaired daytime functioning. RLS is associated with a significant impairment of quality of life, comparable with that seen in chronic medical conditions such as diabetes or depression. Given the significant burden of morbidity associated with RLS, there is a strong case for treatment in patients with troublesome symptoms.
