Review Case Reports[Functional disorder of the hypothalamic osmoreceptor as the cause of excessive hypernatremia in a girl with absence epilepsy].
Chronic hypernatremia is a rare disorder in childhood and normally results from impairment of the water homeostasis. In some cases, chronic hypernatremia is caused by decreased intake of water based on impaired thirst perception. ⋯ In summary, we speculate that the chronic hypernatremia in our patient is caused by a selective hypothalamic osmoreceptor dysfunction associated with mild dysplasia of the midline structures. Only very few similar cases have been documented in the literature.
