Abstract: Narcolepsy is a rare disease that presents with sleep-wake disorder, which divided into narcolepsy type 1 (NT1) and narcolepsy type 2 (NT2). NT1 accounts for more than 75%, which is characterized by excessive daytime sleepiness (EDS), cataplexy attacks and nocturnal sleep symptoms (e.g. sleep paralysis, hallucinations, sleep disruptions, sleep movement disorders, etc.), accompanied by metabolic, psychiatric and emotional disturbances. The main clinical manifestation of NT2 is EDS, without cataplexy and nonspecific other symptoms of NT1. The treatments of narcolepsy mainly include the treatments of EDS and cataplexy, as well as the improvement of nocturnal sleep. This article will elaborate the advances in clinical manifestations and treatments of narcolepsy.
