Purpose Of ReviewIn the review period since February 2004 a number of papers have been published that make significant contributions to the current understanding of the epidemiology, clinical assessment, pathophysiology and treatment of restless legs syndrome. Those with the most significant findings were selected and will be reviewed.Recent FindingsSeveral epidemiological studies about restless legs syndrome have become available in the review period. A new susceptibility locus for restless legs syndrome has been reported. Neuropathological studies have provided profound insights into the key role of iron regulation in the pathophysiology of restless legs syndrome. Several randomized, double-blind, placebo-controlled studies have demonstrated that dopamine agonists are efficacious in the treatment of restless legs syndrome. A few pilot treatment studies with intravenous iron have been performed.SummaryIn this paper, recent advances in the field of restless legs syndrome are reviewed. Special emphasis is placed on pathophysiology and treatment. Restless legs syndrome is still an underdiagnosed disorder. The evidence basis for its treatment has been considerably increased in the review period.
