Abstract
Evidence for tissue iron deficiency in restless legs syndrome (RLS) is limited to the substantia nigra (SN). Using MRI, we assessed T2 values of various brain regions in 6 RLS patients and 19 controls and correlated them with sonographically assessed SN echogenicity. Both neuroimaging features are supposed to correlate with tissue iron content. Mean T2 values of all regions were higher in patients (2.9β7.8%), though significantly increased only in four regions; the mean T2 over all voxels was higher in patients (5.1%, P < 0.001) and correlated inversely with SN echogenicity (r = β0.61, P < 0.001). This indicates multiregional (global) brain iron deficiency in RLS and proposes SN echogenicity as a potential morphological marker for brain iron status. Β© 2008 Movement Disorder Society

The impressive relief from restless legs syndrome (RLS) symptoms provided by levodopa treatment indicates RLS is caused by a dopaminergic abnormality. But similar and more lasting relief also occurs for iron treatment in some patients. Thus there are two major putative causes for RLS: CNS dopaminerg
## Abstract Restless legs syndrome (RLS) and Tourette's syndrome (TS) share some common features, including the phenomenology of sensations relieved by movements, but few studies have examined the links between RLS and TS. We examined RLS and other TS comorbidities in 144 probands with TS or chroni
## 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
