睡眠行動障害
Wikipedia definition
1. Rapid eye movement behavior disorderRapid eye movement sleep behaviour disorder (RBD) is a sleep disorder (more specifically a parasomnia) that involves abnormal behaviour during the sleep phase with rapid eye movement (REM sleep). It was first described in 1986. The major and arguably only abnormal feature of RBD is loss of muscle atonia during otherwise intact REM sleep. This is the stage of sleep in which most vivid dreaming occurs. The loss of motor inhibition leads to a wide spectrum of behavioural release during sleep.
