REM Behavior disorders (RBD) is a condition in which people violently act out their dreams during REM sleep, putting them and others at the risk of injury. For people with RBD the paralysis that normally accompanies REM sleep is incomplete or absent making REM sleep unsafe. A recent study found that patients with violent RBD have a high probability of later developing Dementia, Parkinson’s disease or Parkinson’s like disorders, all of which seem to be caused by a similar Neurodegenerative process. The results reveal that patients with RDB may actually be exhibiting the early stages of Neurodegenerative diseases such as Parkinson’s disease or dementia.
