Abstract

We aimed to investigate the prevalence of restless legs syndrome (RLS) according to essential diagnostic criteria, and to explore potential associations with clinical features, especially motor fluctuations, in a cohort of 113 patients with idiopathic Parkinson's disease (PD). Twenty‐eight (24%) fulfilled essential diagnostic criteria for RLS. They were younger (63.1 ± 8.6 vs. 68.8 ± 9.0 years; P = 0.004), had an earlier onset of PD (54.1 ± 9.5 vs. 59.2 ± 10.3 years; P = 0.018), and received lower levodopa equivalent doses (578.4 ± 382.2 vs. 779.1 ± 459.6 mg/day; P = 0.04) than patients with PD who scored negative for RLS. In 23 patients (82%), RLS symptom onset was after PD onset (mean interval, 4.5 ± 3.7 years). The majority (n = 17, 61%) who scored positive for RLS reported that the urge to move the legs and unpleasant sensations were associated with wearing off, raising the possibility of RLS mimics in fluctuating patients with PD. © 2009 Movement Disorder Society

## Abstract Parkinson's disease (PD) and restless legs syndrome (RLS) have a dopaminergic link. More insight in the clinical profile of RLS in patients with PD may benefit our understanding of this link.

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

## Abstract Substantia nigra (SN) hyperechogenicity assessed by transcranial brain sonography (TCS) is a characteristic finding in idiopathic Parkinson's disease (PD). In contrast, SN hypoechogenicity on TCS has been recently demonstrated in restless legs syndrome (RLS). RLS is one of the most comm
