Stroke-related restless legs syndrome: epidemiology, clinical characteristics, and pathophysiology

Stroke-related restless legs syndrome (RLS) is one of stroke-related sleep disorders, which may be due to de novo RLS after stroke onset or an exacerbation of RLS symptoms after incident stroke. To date, the diagnostic rate of stroke-related RLS is low but it has a significant effect on patients' daily life and functional outcome. This review provides an overview of the epidemiology, clinical characteristics, pathophysiology, and impact on functional outcome of stroke-related RLS.
