Overview
Many doctors express the view that the incidence of restless leg syndrome is exaggerated by manufacturers of drugs used to treat it.[1] Other physicians consider it a real entity that has specific diagnostic criteria. [2]
Epidemiology and Demographics
Often sufferers think they are the only ones to be afflicted by this peculiar condition and are relieved when they find out that many others also suffer from it. The severity and frequency of the disorder vary tremendously. Many people only experience symptoms when they try to sleep, while others experience symptoms during the day. It is common to have symptoms on long car rides or during any long period of inactivity (like watching television or a movie, attending a musical or theatrical performance, etc.) Approximately 80-90% of people with RLS also have PLMD, Periodic Limb Movement Disorder, which causes slow "jerks" or flexions of the affected body part. These occur during sleep (PLMS = Periodic Limb Movement while Sleeping) or while awake (PLMW - Periodic Limb Movement while Waking).
Developed Countries
Restless legs syndrome affects an estimated 2.7% of the general population in the U.S.A..[3]
Developing Countries
About 10 percent of adults in North America and Europe may experience RLS symptoms, according to the National Sleep Foundation, which reports that "lower prevalence has been found in India, Japan and Singapore," indicating that ethnic factors, including diet, may play a role in the prevalence of this syndrome.[4]
