Abstract

Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by an absence of normal skeletal muscle atonia during REM sleep and clinical features of disturbing dreams and dream enacting behaviors. Hence, the common sequelae are sleep-related injury and violence to both patients and bed-partners. Although polysomnographic evidence of REM sleep without atonia, is regarded as a gold standard for the confirmation of RBD diagnosis, polysomnography is both time and resource consuming. In order to facilitate early detection and clinical management, developing a convenient and suitable screening tool to identify individuals at risk of RBD would enable physicians to prioritize those who may require timely assessment and clinical intervention. In addition, the longitudinal course of RBD and its prognostic implication in predicting neurodegenerative disorders may suggest a potential therapeutic window for early preventive management of underlying progress of neurodegeneration. The availability of suitable RBD scales may facilitate timely assessment, accurate diagnosis and monitoring of disease progress of RBD. The present paper summarized recent research on the development of screening tools of RBD, their psychometric properties, and the applications of these questionnaires.
