Question: What is the outlook for Restless Legs Syndrome ?
Answer: 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 individuals have remissions, periods in which symptoms decrease or disappear for days, weeks, or months, although symptoms usually eventually reappear.
