REM sleep behavior disorder (RBD) now attracts much interest from the neurology community, mostly because RBD was incorporated with the revised clinical diagnostic criteria of dementia with Lewy bodies (DLB) as one of the core clinical features in 2017. It has been also well established that RBD often precedes other symptoms and signs of synucleinopathies. Under this circumstance, neurologists should understand what RBD is and to make an early diagnosis of RBD. However, historically RBD was classified as one of the parasomnias with a long history of sleep research, and patients with isolated/idiopathic RBD seek medical help for violent or potentially harmful behaviors during sleep. In this symposium, the speakers from different subspecialties are going to focus this dual nature of RBD. We expect the audience to obtain in-depth knowledge about RBD.
