[The Klein-Levin syndrome (a case)].

The author provides a detailed description and a clinical analysis of a case of Kleine-Levin syndrome. Reviews the psychopathological characteristics of the patient with Kleine-Levin syndrome. Hypersomnic attacks occurred in an epileptoid personality at an age of 14 years, each attack was coupled with affective derealization symptomatology. The epileptic nature of the disease is not supported by the EEG data. It is suggested that the psychopathological symptomatology of the hypersomnic attack is consequent on the derangement of mediator regulation of hypothalamic functions.
