Intraindividual variability of REM sleep behavior disorder in Parkinson's disease: a comparative assessment using a new REM sleep behavior disorder severity scale (RBDSS) for clinical routine.

ABSTRACT:

Objectives

To develop a polysomnographic video-based scale for rating the severity of REM sleep behavior disorder (RBD), to classify the severity of RBD and to determine the intraindividual variability of RBD in patients with Parkinson disease (PD).

Methods

Twenty PD patients identified with RBD were investigated with video-supported polysomnography (PSG). Seventy-three motor behavior events during REM sleep were graded visually and polysomnographically on an event-to-event basis according to categorical location of movements: "0" = no visible movement; "1" = slight movements or jerks "2" = movements involving proximal extremities, including violent behavior; "3" = axial involvement including bed falls. Vocalizations were rated as "1" for present or "0" for absent. Ratings w
