Successful Long-term Management of a Child with Kleine-Levin Syndrome with Low-dose Lithium

Kleine-Levin syndrome (KLS) is a rare disorder characterized by episodic hypersomnia along with cognitive and behavioral disturbances (i.e., hyperphagia and hypersexuality). It is commonly seen in a young male. Not much is known about its long-term management; however, many reports suggest the usefulness of anticonvulsants and lithium for the same. We hereby report a case of childhood KLS from India who was successfully treated with low-dose lithium and discuss the relevant literature.
