Abstract
Kleine-Levin syndrome is classified as a sleep disorder characterized by recurring episodes of hypersomnolence, compulsive overeating, mental status, and behavioral changes. The disorder is rare, occurring up to four times more often in males than in females with an onset usually in adolescence. In about 50% of cases a specific circumstance can be identified at the onset of the first episode.
Episodes may develop gradually or abruptly and may last less than 24 hours or persist for several months. The syndrome may recur at varying intervals from several weeks to many months and seems to decrease and eventually cease with time; however, more recent reports are suggesting persistent personality, behavioral or cognitive impairment. Although a variety of interventions has been reported, there is no definitive treatment.
This case report serves as a reminder to clinicians caring for adolescents and adults to include Kleine-Levin Syndrome in the differential diagnosis of remitting and relapsing psychiatric symptoms.
