REM Sleep Behavior Disorder Single-Question Screen
{{Short description|Screening for dream enactment behaviors}}
The REM Sleep Behavior Disorder Single-Question Screen (RBD1Q) is a one-question screening tool for dream enactment behaviors associated with the parasomnia REM sleep behavior disorder (RBD). It screens for RBD with a simple yes/no response.
Format
The RBD1Q queries dream-enactment behavior of RBD with a single yes/no question:{{cite journal |vauthors=Postuma RB, Arnulf I, Hogl B, et al |title=A single-question screen for rapid eye movement sleep behavior disorder: a multicenter validation study |journal=Mov. Disord. |volume=27 |issue=7 |pages=913–6 |date=June 2012 |pmid=22729987 |pmc=4043389 |doi=10.1002/mds.25037}}
"Have you ever been told, or suspected yourself, that you seem to 'act out your dreams' while asleep (for example, punching, flailing your arms in the air, making running movements, etc.)?"
It has a sensitivity of 94% and a specificity of 87% in detecting RBD.
Applications
The RBD1Q can be used to establish a diagnosis of REM sleep behavior disorder in Parkinson's disease{{cite journal |vauthors=Munhoz RP, Moro A, Silveira-Moriyama L, Teive HA |title=Non-motor signs in Parkinson's disease: a review |journal=Arq Neuropsiquiatr |volume=73 |issue=5 |pages=454–62 |date=May 2015 |pmid=26017214 |doi=10.1590/0004-282X20150029 |type= Review |doi-access=free }} and dementia with Lewy bodies.{{cite journal |vauthors=McKeith IG, Boeve BF, Dickson DW, et al |title=Diagnosis and management of dementia with Lewy bodies: Fourth consensus report of the DLB Consortium |journal=Neurology |volume=89 |issue=1 |pages=88–100 |date=July 2017 |pmid=28592453 |pmc=5496518 |doi=10.1212/WNL.0000000000004058 |type=Review }}
Development
Other screening tools for RBD are lengthy and difficult to use for epidemiological studies, needed to determine the prevalence of RBD.
Participants for a case-control study were recruited from twelve centers of the International REM Sleep Behavior Disorder Study Group between 2008 and 2011. The 484 participants (242 individuals with polysomnogram-confirmed RBD and 242 controls) completed the screen. Dream-enactment behavior was established by history or video recording, and the absence of REM sleep muscle paralysis (atonia) was confirmed by polysomnogram, according to the International Classification of Sleep Disorders-2.
