Rapid Eye Movement sleep Behavior Disorder Screening Questionnaire (RBDSQ) is a specific questionnaire for RBD to assess the most prominent clinical features of RBD according to the International Classification on Sleep Disorders [1]. It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or 'no'. [2]. The questionnaire is observed to perform with high sensitivity and reasonable specificity. Although, the performance is good, for a definitive diagnosis polysomnography is required to definitely rule out differential diagnoses such as sleep-related epileptic seizures, non-REM parasomnias (e.g., sleepwalking), obstructive sleep apnea (OSA), or nocturnal periodic leg movements (PLM)[1].
RBDSQ has the potential to be useful as a screening instrument for neurodegenerative disorder, such as the α-synucleinopathies, Parkinson’s disease or multiple system atrophy which may enable early diagnosis and also recruitment of RBD patients necessary for research studies as well as for therapeutic trials.
