Résumé
Restless legs syndrome is a common motor-sensory disease of the nervous system. The main manifestations are an urge to move the legs, usually accompanied by or thought to be caused by uncomfortable and unpleasant sensations in the legs. These symptoms may begin or worsen during periods of rest or inactivity such as lying down or sitting and be partially or totally relieved by movement, such as walking or stretching, at least as long as the activity continues. This article will systematically review the pathogenesis, clinical manifestations, diagnostic criteria, differential diagnosis and treatment of restless legs syndrome.
Résumé
Parkinson's disease(PD)and restless legs syndrome(RLS)are relatively common movement disorders.There has been much debate over whether an etiological link exists between these two diseases and whether they share common pathophysiological mechanisms.PD and RLS may co-occur and respond well to dopaminergic agents, suggesting there is underlying dopamine dysfunction in both conditions.Despite the overlapping clinical features, the mechanisms underlying idiopathic RLS and RLS associated with PD may differ.In this article, we review studies related to the epidemiology, pathophysiology and genetics of PD with concurrent RLS, in order to provide evidence for exploring the link between RLS and PD.
