Abstract
- Kleine-Levin syndrome is characterized by recurrent episodes of hypersomnia and associated cognitive and behavioral impairments. We present a 47-year-old female patient with recurrent hypersomnia and disorder of appetite. During each episode, patient slept more than 24 hours with hyperphagia or anorexia. Physical examinations, laboratory tests, and brain MRI showed no significant abnormality in the patient. Nocturnal polysomnographic study showed high sleep efficiency, reduced sleep latency and rapid eye movement (REM) sleep latency, and increased sleep stage 1 & 2. The multiple sleep latency tests showed one episode of sleep-onset REM periods. This is the first atypical case report of Kleine-Levin syndrome in Korea which showed short duration of episodes and hypersomnia combined with anorexia.
