PD = Parkinson’s disease; RLS = restless leg syndrome; UPDRS III = unified Parkinson’s disease rating scale III; PRBD = probable rapid eye movement sleep behavior disorder; MMSE = minimum mental state examination; HAMD = Hamilton depression scale; daily LED = daily levodopa equivalent dose; tips for positive correlation, between the severity of RLS in PD patients with duration of PD or daily LED.
