Restless legs syndrome (RLS) is a sensorimotor disorder characterized by a distressing urge to move the legs and sometimes other parts of the body. Diagnosis is based on clinical features that may be easily remembered with the mnemonic URGE: Urge to move, Rest induced, Gets better with activity, and Evening and night accentuation. RLS is common, its prevalence increases with age, and women are more frequently affected. ⋯ Primary RLS is familial and likely to be genetic. Important causes of secondary RLS are end-stage renal disease, pregnancy, and iron deficiency. Every patient should be checked for iron status with a serum ferritin measurement.
