Kleine-Levin Syndrome Treated with Carbamazepine: A Case Report

Kleine-Levin syndrome (KLS) is characterized by recurrent episodes of hypersomnia frequently associated with behavioral or cognitive disturbances, compulsive eating behavior, and hypersexuality. Although the syndrome is rare, it is important that clinicians be aware of this syndrome and distinguish it from organic or psychiatric diseases with more serious prognoses. Here, we report the case of a 14-year-old adolescent male with KLS, who showed significant improvement with carbamazepine during follow-up to age 26. This study describes the clinical course of KLS and results of long-term follow-up of carbamazepine treatment. (Arc-hi-ves of Neu-ropsy-chi-atry 2012; 49: 71-3)
