Armodafanil for the treatment of Kleine-Levin syndrome

Kleine–Levin syndrome (KLS) is a rare disorder characterized by recurrent episodes of hypersomnia and to various degrees, behavioral or cognitive disturbances, compulsive eating behavior, and hypersexuality. There is no definite treatment for KLS and several pharmacological agents have been tried with variable success. We report the case of a young male with KLS who showed a favorable response to armodafinil.
