Narcolepsy is a chronic disabling neurological disorder, often unrecognized and misdiagnosed. It is often confused with psychiatric conditions and not properly treated. It is a clinical syndrome consisting of classic tetrad of symptoms (often incomplete, making diagnosis challenging). It is characterized by disruption of sleep/wake cycle, where rapid eye movement physiology intrudes into wakefulness and vice versa. It is caused by loss of hypothalamic neurons producing hypocretin. Onset might be heralded by a viral illness. Continuous pharmacotherapy is as equally important as modification of behavior, sleep hygiene, education, and emotional support. This case illustrated the challenges that could represent its proper diagnosis and management.KeywordsNarcolepsy with cataplexyHypocretinExcessive daytime sleepinessMultiple sleep latency test
