Kleine-Levin syndrome
A rare condition characterized by excessive need for sleep, food, and sexual disinhibition.
Most people with Kleine-Levin syndrome are adolescent males.
When awake, they may be confused, irritable, and lethargic, and some have hallucinations.
The cause is unknown, although current theory holds that Kleine- Levin syndrome is caused by an inherited autosomal dominant trait that affects the hypothalamus gland.
Most cases resolve over time without treatment
