Narcolepsy (NRL) is a rare chronic central nervous system dysfunction disease, which is more common in children and adolescents, and less common in adults. Its typical clinical features include excessive daytime sleep, paroxysmal cataplexy, sleep paralysis and sleep hallucination. In addition to the above typical manifestations, patients with narcolepsy can also manifest as hyperappetite, weight gain, multiple dreams, sleep fragmentation, anxiety and depression and other emotional disorders. In particular, in narcolepsy type 1 with cataplexy, cataplexy episodes can be confused with falls caused by seizures, transient ischemic attacks or neuromuscular disorders, or even mental conversion disorders. Due to its diverse clinical symptoms, it is easy to be missed and misdiagnosed. At present, the pathogenesis of narcolepsy is still unclear, and its pathogenesis may be related to immune, genetic, environmental, infection, central nervous system degeneration and other factors. This study aims to investigate the changes of body fluid proteomics and metabolomics in patients with narcolepsy, and to provide an important basis for the pathogenesis of narcolepsy.
