- Abstract: Rapid eye movement sleep behavior disorder (RBD) is a sleep disorder characterized by loss of muscle atonia during REM sleep associated with dream enactment, which usually start at the age of older than 50. RBD in elders are known to be developing symptoms of neurodegenerative disorders in the course of disease. However, the pathophysiology and prognosis of "early-onset" idiopathic RBD is unclear. Several existing standard value about REM sleep without atonia (RSWA) of RBD patients was established with "late-onset" RBD for those diagnosed at age 50 and greater, RSWA metrics in "early-onset" RBD patients diagnosed prior to age 50 years have not been previously described. Therefore, we report here two patients who were diagnosed as "early-onset" idiopathic RBD, and performed quantitative RSWA scoring. We suggested that "early-onset" idiopathic RBD has different etiologies the various characteristics of RSWA than adults with RBD.
