Adipsia is a disease characterized by the absence of thirst even in the It is a rare condition that typically presents as hypernatremic dehydration. We describe two sisters with chronic hypernatremia, lack of thirst, and inappropriate osmoregulated vasopressin secretion. Only one sister, who presented with. Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent . Type A (essential hypernatremia syndrome) involves an increase of the level in which solvent molecules can pass through cell membranes (osmotic.

Oxford University Press; Other findings in support of the role of dopamine in thirst regulation involved the nigrostriatal pathway.

Adipsic hypernatremia in a patient with pseudotumor cerebri and the primary empty sella syndrome.

Adipsia can tend to result from lesions to hypothalamic regions involved in thirst regulation. Report of three cases and review of the literature.

Chronic and sustained hypernatremia, absence of thirst, diabetes hypernatremi, and adrenocorticotrophin insufficiency resulting from widespread destruction of the hypothalamus. Lesions or injuries to those hypothalamic regions cause adipsia because the lesions cause defects in the thirst regulating center which can lead to adipsia. As they did not show overeating, we believe the obesity may result from a disorder of energy balance.

This type may be due to some elimination of osmoreceptors. Although minimal, there is still some secretion of Hypeenatremia. Please review our privacy policy. New strategies to prevent specific inflammatory conditions would be required to treat these patients; a trial to reduce or eliminate patient autoantibodies deserves consideration.

Support Center Support Center. People affected by adipsia lack the ability to feel thirst, thus they often must be directed to drink. All patients were regularly managed by our team of pediatric endocrinologists, adipsiic individual adjustment of fluid intake, as a function of the thirst abnormality, and with nasal or, preferably, oral once it became available DDAVP, initially administered once, twice, or three times daily.
