Kleine-Levin syndrome.

ABSTRACT

Kleine-Levin Syndrome (KLS) is a rare disorder of uncertain etiology, characterized by recurring episodes of undue sleepiness lasting for days. We report a case of young female presenting with episodes of undue sleep along with hypersexuality and excessive food intake, who improved significantly on lithium and valproate. KLS should be considered in young patients, who present with episodes of undue somnolence.
