Restless legs syndrome (RLS) is a generally underdiagnosed and undertreated condition. It is a common cause of sleep disturbance that can severely disrupt normal life functioning. However, because of the failure to recognize RLS as a distinct disorder, clinicians have minimized the significance of the morbidity experienced by some patients. A positive family history is present in >50% of patients with RLS. Indeed, a person with RLS is 3 to 6 times more likely to have a positive family history of RLS than is an individual who does not have the disease. The differential diagnosis of RLS includes both movement and sleep disorders. Establishing an accurate diagnosis is crucial because effective treatment is available. In 2002, RLS experts revised diagnostic criteria and established 4 essential criteria for the diagnosis. Assessing the most bothersome symptoms and quantifying the severity of RLS are important because not all patients require medical therapy. Moreover, therapy may vary according to which symptom represents the major problem.
