REM Sleep Behavior Disorder Screening Questionnaire explained

REM Sleep Behavior Disorder Screening Questionnaire
Purpose:	Diagnosis of rapid eye movement behavior disorder
Based On:	Questionnaire

The REM Sleep Behavior Disorder Screening Questionnaire (RBDSQ) is a specific questionnaire for rapid eye movement behavior disorder (RBD) developed by Stiasny-Kolster and team,^[1] to assess the most prominent clinical features of RBD.^[2] It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or 'no'.^[1] The validity of the questionnaire was studied by researchers and they have observed it to perform with high sensitivity and reasonable specificity in the diagnosis of RBD.^{[3] [4] [5]}

Use

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 people with RBD necessary for research studies.

Format

RBDSQ contains a set of 10 items that are to be answered by either 'yes' or 'no'. Items 1 to 4 address the frequency and content of dreams and their relationship to nocturnal movements and behavior. Item 5 asks about self-injuries and injuries of thebed partner. Item 6 consists of four subitems assessing nocturnal motor behavior more specifically, e.g., questionsabout nocturnal vocalization, sudden limb movements, complex movements, or bedding items that fell down. Items 7 and 8 deal with nocturnal awakenings. Item 9 focuses on disturbed sleep in general and item 10 on the presence of any neurological disorder. The maximum total score of the RBDSQ is 13 points.
