Restless legs syndrome and periodic limb movements after lacunar stroke

Although anatomical and physiological considerations suggest a possible causality between subcortical brain areas lesions and emergence of sleep-related movement disorders, few data are available regarding the association between restless legs syndrome/periodic limb movements (RLS/PLM) and lacunar stroke [1]. The aim of this study was to evaluate the prevalence and the lesion topography of new-onset RLS/PLM in patients with lacunar stroke. In addition, we tried to add some details about the characterization of sleep-related movement disorders in relation to the site and side of the ischemic lesion.
