REM Sleep Behavior Disorder Screening Questionnaire
The REM Sleep Behavior Disorder Screening Questionnaire is a specific questionnaire for rapid eye movement [behavior disorder] developed by Stiasny-Kolster and team, to assess the most prominent clinical features of RBD. It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or 'no'. 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.
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
