Restless legs syndrome (RLS), first described in 1672 and given its name in 1945, is one of the most common sleep and movement disorders. Modern population-based studies demonstrate a prevalence between 5% and 15% in adult white populations. According to the diagnostic criteria, RLS is defined as an irresistable desire to move limbs, usually associated with paresthesias/dysesthesias and motor restlessness. ⋯ A majority of the patients treated over a longer period of time with L-dopa, however, develop problems with an effect called augmentation, where the RLS symptoms begin appearing earlier during the day and involve new parts of the body with increasing severity. A large number of studies have now confirmed that dopamine agonists can also be effective in RLS therapy, and that this treatment seems to involve less risk for augmentation. This paper provides a general review of RLS with a focus on current treatment options.
