Restless legs syndrome (RLS) may affect up to 10% of the U.S. population. It affects both sexes, but is more common in women and may begin at any age, even in young children. Most people who are affected severely are middle-aged or older.
RLS is often unrecognized or misdiagnosed. This is especially true if the symptoms are intermittent or mild. Once correctly diagnosed, RLS can often be treated successfully.
