REM Sleep Behavior Disorder Single-Question Screen

REM Sleep Behavior Disorder Single-Question Screen is a simple, yet effective screening tool used to identify individuals who may be at risk for developing Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD). REM Sleep Behavior Disorder is a sleep disorder characterized by abnormal behaviors and movements during the REM stage of sleep, where a person physically acts out their dreams. This can lead to injuries for both the individual and their bed partner. Early detection and proper management of RBD can significantly improve the quality of life for those affected.

Screening Question

The REM Sleep Behavior Disorder Single-Question Screen consists of a single question that aims to identify the presence of dream-enactment behaviors:

• "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.)?"
• A positive response to this question may indicate the presence of REM Sleep Behavior Disorder and warrants further evaluation by a sleep specialist.

Limitations and Further Evaluation

• While the REM Sleep Behavior Disorder Single-Question Screen is a quick and straightforward method for identifying individuals who may have RBD, it is not a definitive diagnostic tool. False positives and negatives can occur. Consequently, if there is a suspicion of RBD, a more comprehensive assessment by a sleep specialist, including a polysomnography (sleep study), is necessary for a definitive diagnosis.

Significance of Early Detection

• Early detection and management of REM Sleep Behavior Disorder are crucial, as RBD can lead to injuries, sleep disturbances, and reduced quality of life for both the affected individual and their bed partner. Furthermore, RBD has been associated with an increased risk of developing neurodegenerative disorders, such as Parkinson's disease and Lewy body dementia. Identifying and treating RBD can help individuals and their healthcare providers address potential complications and take preventive measures to minimize the risk of more serious conditions.
