REM behavior disorder (RBD) can be one of the first symptoms of childhood narcolepsy SLEEP MEDICINE Nevsimalova, S., Prihodova, I., Kemlink, D., Lin, L., Mignot, E. 2007; 8 (7-8): 784-786


More than one in three adult patients suffering from narcolepsy-cataplexy experience rapid eye movement (REM) behavior disorder (RBD), while RBD in childhood is extremely rare. We present the cases of two girls (aged 9 and 7 years old) with narcolepsy-cataplexy, in whom RBD was one of the first symptoms of the disease. The coincidence of RBD was seen by nocturnal video-polysomnography (v-PSG), and narcolepsy was diagnosed from short sleep latency and multiple sleep onset REMs (SOREMs) during a multiple sleep latency test (MSLT). Both girls were human leukocyte antigen (HLA)-DQB1 *0602 positive, and their cerebrospinal fluid (CSF) hypocretin level (Hcrt-1) was extremely low.
