Aim: Differently from previous studies that directly compared Parkinson's disease (PD) patients with and without rapid eye movement (REM) sleep behavioural disorder (RBD) for the stage, severity, and duration of disease, this study investigated the relationship between the duration and clinical severity of disease in PD patients with and without RBD.
