Hypersomnolence is becoming an important problem in adolescents because of the change of lifestyle. Narcolepsy is a chronic and incurable sleep disorder, classically presenting with excessive daytime sleepiness associated with cataplexy, hypnagogic hallucinations, sleep paralysis and nocturnal sleep fragmentation. It\'s most common presenting symptom and essential feature is excessive daytime sleepiness. Diagnosis is often missed in India because of lack of proper sleep labs and training to diagnose this disorder
This case highlights the need to keep Narcolepsy among the common differentials for adolescents presenting with excessive daytime sleepiness, while also looking for other common causes of the same. A detailed approach to the same is also discussed.
