Chapter 29 Introduction to Management of Restless Legs Syndrome
As demonstrated by the chapters that follow, there are numerous therapies that have been tried for the restless legs syndrome (RLS), and for many of them there is some evidence of success. Although it is fairly easy to summarize—and assess—the evidence for specific treatments, a management plan has been more a matter of expert opinion. The basis for management was set out by the American Academy of Sleep Medicine (AASM) Standards and Practice Committee (SPC) in their first standards for RLS treatment in 1999.1 That document specific elements that were standards, that is, essentially mandated (the SPC indicates that a standard is, “a generally accepted patient-care strategy which reflects a high degree of clinical certainty”), for the proper management of RLS patients:
The one publication presenting a somewhat comprehensive algorithm for management was produced several years ago by the Medical Advisory Board of the RLS Foundation (RLSF).2 By now, some of its specific recommendations are somewhat outdated, but the general scheme remains quite valid. First, the algorithm suggests three major classes of patients—those with intermittent RLS who may need only occasional therapy, those with daily or near-daily RLS who will benefit from daily medication, and those who have become refractory to initial first-line therapy, especially those who cannot tolerate or have developed augmentation on one or more agonists. Second, the scheme indicates that nonpharmacological therapy, mainly behavioral therapy and the avoidance of provocative substances, is something that should be incorporated into the management scheme for all patients, even if pharmacological therapy is also mandated. Third, the scheme recognizes the importance of assessing iron status and treating iron deficiency if it exists. Fourth, the algorithm suggests ways to manage the various classes of patients (Table 29-1).
