Abstract

Although restless legs syndrome (RLS) commonly accompanies Parkinson disease (PD), the mechanism of RLS development in PD is still unclear. We investigated the prevalence of RLS in Korean patients with PD, and the possible contributing factors to the development of RLS in those patients. Four hundred forty‐seven consecutive patients with PD were interviewed and examined. Among them, 73 patients (16.3%) were diagnosed with RLS. PD patients with RLS had a longer duration of PD symptoms, more severe PD disability, a greater degree of cognitive decline, and a longer duration of antiparkinson therapy than those without RLS. Multivariate logistic regression analysis revealed that the duration of antiparkinson therapy was the most significant factor contributing to the development of RLS in patients with PD. The present results support a higher prevalence of RLS in patients with PD and suggest that long‐term antiparkinson therapy, rather than PD itself, may contribute to the development of RLS.

## Abstract The cause of restless legs syndrome (RLS) is unknown, but an involvement of the dopaminergic system and a possible relation to Parkinson's disease (PD) is suggested by the positive response to dopaminergic treatment.

The pathophysiology of restless legs syndrome (RLS) is associated with central dopaminergic system dysfunction leading to speculations that RLS may be common in those neurodegenerative diseases with dopaminergic cell loss. However, since RLS is a very common condition, the co-occurrence with less fr
