Restless Leg Syndrome (RLS) is a neurological condition that is usually associated with disturbed sleep. According to the NSF’s Sleep in America poll, 9.7% of American adults experience RLS at least a few times a week. A recent study of 283 patients over the age of 50 in Spain, found that the prevalence of RLS was 11.6% among this population and that women were 3 times more likely to report RLS symptoms than men. Only 15% of the patients reported a major impact of symptoms on their health, yet an association between RLS and frequent doctor visits, day time sleepiness and the use of Hypnotics was observed.
