**7. Conclusion**

RBD is a complex night time behavior consisting of dream enactment due to the loss of physiologic REM muscle atonia. It can be classified as idiopathic, which is in many cases a non-motor symptom of the alpha synucleinopathies. This group of neurodegenerative illnesses includes Parkinson's disease, Lewy body dementia, and multiple system atrophy. The importance of understanding REM sleep behavior disorder and its implications cannot be overstated. Clinical suspicion and appropriate history taking, supports an early diagnosis and symptomatic management. More importantly, treating physicians are able to educate and monitor patients for the development motor symptoms suggestive of neurodegenerative disease. This window of opportunity allows for enrollment in clinical trials and emerging therapies. Secondary RBD related to structural lesions or medications is important to recognize in order to discontinue the offending agent and decrease the risk of night time injury. Medical management with melatonin or clonazepam can reduce the episodes of dream enactment. Non-medical interventions such as ensuring a safe sleeping environment can help prevent injury.
