Heart rate changes according to the complexity of motor events in REM sleep behavior disorder

Reduced Heart Rate Variability (HRV) is considered a marker of autonomic system dysfunction in REM sleep behavior disorder (RBD) (Fantini et al. 2002; Sorensen et al. 2012). Blunted Heart Rate (HR) response was described in RBD and Parkinson's Disease (PD) patients following limb movements during sleep (Fantini et al. 2002; Sorensen et al. 2012) and in PD after arousals (Sorensen et al. 2012). We found no study on the effect of RBD motor events (ME) on HR. RBD related ME can be classified in two types: short lasting, small amplitude, non-purposeful movements and complex, scenic ones, in which patients enact the content of their dreams, usually negative or violent (Frauscher et al.
