Restless legs syndrome is a neurological disorder characterized by intense urges to move the legs, typically in supine positions and accompanied by uncomfortable periodic prickling sensations. Exact cause is unknown, but several underlying conditions are thought to be associated with restless leg syndrome, including iron deficiency, kidney failure and peripheral nerve disease.
Restless legs syndrome (RLS) is a disorder marked by unpleasant sensations in the legs and an irresistible urge to move the legs, usually while resting or when going to sleep. The discomfort is sometimes described as pain, tingling or crawling, and patients seek relief by moving the legs.
Severity of each symptom varies, but RLS can greatly impact sleep quality, resulting in exhaustion, daytime fatigue, poor concentration and depressive symptoms.
The exact cause of RLS is not known, but pathways in the brain affected by Parkinson’s disease are thought to be relevant. Patients with Parkinson’s disease often have RLS, too.
