Kleine-Levin Syndrome in a young woman: A case report

Introduction: Klein-Levin Syndrome (KLS) is a rare disorder identified by recurrent hypersomnia, over-eating, or hypersexuality and is associated with cognitive dysfunction or abnormal behaviors. Case presentation: In this paper, we presented a 36-year-old single female with chief complaints of headaches, tiredness, and sleepiness. She reported attacks of hypersomnia and memory deficits from childhood. She experienced addiction to alcohol, caffeine, and sugar, also depression, and suicidal taught. The full medical work-up did not indicate any organic illness. Polysomnography and Multiple Sleep Latency Tests indicated narcolepsy. Finally, she was diagnosed with Klein-Levin syndrome. Conclusion: Kleine-Levin Syndrome is a challenging diagnosis. The medical history of clinical symptoms and exclusion of other diagnoses can lead to better diagnosis in patients with hypersomnolence.
