A 15 year-old girl who was previously well presented with severe recurrent episodic hypersomnia associated with abnormal behavior and hyperphagia after recovery from a mild upper respiratory tract infection (URTI). Physical examination was unremarkable with normal blood tests, brain imaging and electroencephalogram (EEG). A multiple sleep latency test (MSLT) during a typical episode showed moderate hypersomnolence in contrast to a normal MSLT performed an the interval between episodes. Clinical features were consistent with Kleine-Levin syndrome (KLS). She was started on carbamazepine treatment after failing a trial of methylphenidate and is currently being followed up for her symptoms.
