REM sleep behavior disorder (RBD): In RBD, the normal muscle atonia that is characteristic of REM sleep is incomplete or absent. Since REM sleep is also characterized by vivid dreaming, patients may have dream enactment that leads to self-injury or may injure their bed partner. In the elderly, RBD can be a prodromal syndrome of alpha-synuclein neurodegeneration such as Parkinson disease, multiple system atrophy, or dementia with Lewy bodies. In younger individuals, other etiologies of RBD should be considered, such as narcolepsy or a side effect of antidepressants that are selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors.
