RLS is characterized by discomfort in the legs that occurs at night while resting and is relieved by movement of the legs. Because of the discomfort in the legs, patients may have difficulty going to sleep and staying asleep. The resulting sleep deprivation can lead to daytime tiredness, poor concentration and loss of energy. Additionally, 80% of people with RLS have excessive movements of the legs while asleep. Bed partners may complain of frequent “kicking” in the bed.
The exact cause of RLS is unknown but it has a primary
form not related to other disorders and a secondary form
related to an underlying condition such as kidney
failure, pregnancy or iron deficiency.
How is RLS diagnosed?
RLS is diagnosed based on clinical history. Some
additional blood labs to detect iron deficiency or
