Restless legs syndrome (RLS) or Willis-Ekbom disease is a neurological disorder characterized by an irresistible urge to move one’s body to stop uncomfortable or odd sensations. It most commonly affects the legs, but can affect the arms, torso, and even phantom limbs. Moving the affected body part modulates the sensations, providing temporary relief. RLS sensations can most closely be compared to an itching or tickling in the muscles, like ‘an itch you can’t scratch’ or an unpleasant ‘tickle that won’t stop.’ The sensations typically begin or intensify during quiet wakefulness, such as when relaxing, reading, studying, or trying to sleep.
As with many diseases with diffuse symptoms, there is controversy among physicians as to whether RLS is a distinct syndrome. The U.S. National Institute of Neurological Disorders and Stroke publishes an information sheet characterizing the syndrome but acknowledging it as a difficult diagnosis. Physicians generally consider it a real entity that has specific diagnostic criteria., but many doctors express the view that the incidence of restless leg syndrome is exaggerated by manufacturers of drugs used to treat it. Others believe it is an underrecognized and undertreated disorder.
