Narcolepsy is considered to be a genetic autoimmune disease of the brain that usually onsets in childhood or adolescence ( 3). Approximately 0.026–0.05% of the US population is affected by this disease, making it a rare condition ( 1, 2) however, we cannot rule out the possibility that many potential patients have not been diagnosed. It is the most common disease that causes daytime sleepiness other than obstructive sleep apnea (OSA). Narcolepsy is a sleep disorder with the main manifestations of excessive daytime sleepiness, cataplexy, sleep paralysis, sleep hallucinations, and nighttime sleep disturbance. Keywords: Narcolepsy sleep disorder polysomnographic (PSG), case report In conclusion, further studies are needed to verify more treatments and improve the patient’s life quality. So far, there is no clear evidence to support immunotherapy. Whether the incidence of narcolepsy may increase after covid19 remains to be observed. Despite the low incidence rate, diagnosis of narcolepsy is still confusing and needs clinicians' attention. Data from China in 2014 showed a significant increase in the incidence of narcolepsy in 2011 after the H1N1 epidemic in China in 2009. We review the knowledge and researches on this disease in Mainland China in the past 10 years. Mutiple sleep latentcy test (MSLT) showed that the average sleep latency was 3.1 min, and abnormal REM sleep episodes were detected in 4 naps. In the present study, we report the first case of narcolepsy diagnosed at the district, with a complete medical history, objective examinations, and cerebrospinal fluid and hematological tests, but no cataplexy.

It is still not fully recognized by clinicians, and many patients are often misdiagnosed with epilepsy, syncope, or mental disorders. Abstract: Narcolepsy is a sleep disorder with the main manifestations of excessive daytime sleepiness, cataplexy, sleep paralysis, sleep hallucinations, and nighttime sleep disturbance.
