title: Rhythmic movements in idiopathic REM sleep behavior disorder.
abstract: Reported are two cases of video-PSG captured head-rolling occurring, in the context of REM Sleep Behavior Disorder (RBD) episodes, in two patients affected with idiopathic RBD and without past personal or familiar history of Rhythmic Movement Disorder during sleep. It has been speculated that the activation of neuronal pathways which underlie REM-related loss of motor control in RBD, may involve the Central Pattern Generator neuronal networks leading to the induction of Rhythmic Movements during RBD episodes, thereby allowing the re-emergence, in pathological conditions in later life, of a motor behavior typically seen in the early stage of life.
