Abstract
Sleep disorders, including REM sleep behavior disorder, are discussed by many mass media these days. An overview of sleep disorders, the specific conditions, precipitating factors, medical treatment of RBD, and also the relation to Parkinson's disease have been discussed. Individuals who worry about RBD after such broadcasts and consult our department have increased in number, therefore, methods to improve dispersal of information on these disorders need to be devised. In addition, in recent years, the relation between sleep disorders and neurodegenerative diseases, the so-called synucleinopathy, including RBD and Parkinson's disease has been talked about, and the involvement of departments of neurology or psychiatry will become important from now on. Management of RBD at this department is being discussed at this time.
