What is Restless Legs Syndrome?

Published:

Restless legs syndrome (RLS) is a neurological disorder characterized by unpleasant sensations in the legs and an uncontrollable urge to move them for relief. Individuals affected with the disorder describe the sensations as burning, creeping, tugging, or like insects crawling inside the legs. The sensations range in severity from uncomfortable to irritating to painful.

Is there any treatment?

For those with mild to moderate symptoms, many physicians suggest certain lifestyle changes and activities to reduce or eliminate symptoms. Decreased use of caffeine, alcohol, and tobacco may provide some relief. Physicians may suggest that certain individuals take supplements to correct deficiencies in iron, folate, and magnesium. Taking a hot bath, massaging the legs, or using a heating pad or ice pack can help relieve symptoms in some patients.

Physicians also may suggest a variety of medications to treat RLS, including dopaminergics, benzodiazepines (central nervous system depressants), opioids, and anticonvulsants. In 2005, ropinirole became the only drug approved by the U.S. Food and Drug Administration specifically for the treatment of moderate to severe RLS.

What is the prognosis?
RLS is generally a life-long condition for which there is no cure. Symptoms may gradually worsen with age. Nevertheless, current therapies can control the disorder, minimizing symptoms and increasing periods of restful sleep. In addition, some patients have remissions, periods in which symptoms decrease or disappear for days, weeks, or months, although symptoms usually eventually reappear.

What research is being done?
The National Institute of Neurological Disorders and Stroke (NINDS) and other institutes of the National Institutes of Health (NIH) conduct and support RLS research in laboratories at the NIH and at major medical institutions across the country. The goal of this research is to increase scientific understanding of RLS, find improved methods of diagnosing and treating the syndrome, and discover ways to prevent it.
