[Kleine-Levin-syndrome (author's transl)].

A report is given on a 18 year old girl with a Kleine-Levin-syndrome, which was studied 4 years after beginning in the menarche. At first there were only attacks of nausea and vertigo. One year later the attacks were combined with hypersomnia for several hours. Remarkable was a minimal overirritability of the right vestibular system and a slight hypersensitivity to touch and pain on the whole right side. Worth mentioning is also a disturbed water balance (retention). A disturbance of the hypothalamic regulation is supposed and methylphenidate-hydrochloride (Rilatin) is commanded for treatment.
