The association between narcolepsy and REM behavior disorder (RBD)

This study implies a stronger relationship between these disorders than a previously published figure of 7-12% [1] This is clinically significant as RBD is a potentially distressing but readily treatable disorder. It follows that narcoleptics, especially those with cataplexy and other associated symptoms, should be questioned about symptoms of RBD and treated accordingly. Similarly, anyone presenting with RBD should be assessed for symptoms of narcolepsy, particularly if female or of a younger age group than would otherwise be expected.
