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.

The efferent projections of the subfornical organ of the rat: The hyperintense signal of the PP was not visible in only two patients. Arch Intern Med ; As expected, the most common abnormality was hypernatremia, although seven patients suffered severe episodes of hyponatremia.

Structure of the subfornical organ: If not treated, Type A adipsia could result in both a decrease in the size of the brain and bleeding in the brain. A hypernatremia without thirst sensation; B impaired AVP release; C lack of structural aberrance in the hypothalamus-pituitary region; D childhood onset; E obesity; F increased serum PRL; G impairment of GH release; H increased plasma renin-activity; and I intact urine-concentrating capacity.


Central diabetes insipidus in children and young adults: Body fluids are therefore constantly monitored by osmolality or sodium level sensors in the brain, which control thirst sensation, preference for salt, and AVP 12.

Conclusion Adipsic hypernatremia patients with specific immune responses to SFO display common clinical features. Clinical data for the patients were obtained from their medical records. Please review our privacy policy.

These results suggest a new etiology for adipsic hypernatremia caused by autoimmune responses. Citing articles via Web of Science 2. Molecular structure of vasopressin. The SFO is a specialized area controlling thirst and salt appetite, as well as several neurosecretory systems with neural connections to other brain nuclei and receptors for circulating peptides.

Receive exclusive offers and updates from Oxford Academic. Adipsic hypernatremia without hypothalamic lesions accompanied by autoantibodies to subfornical organ.

Aa, Patient 5; T1-weighted coronal view: SFO damage by autoimmune response is thought to induce a variety of symptoms, including loss of thirst sensation, hypernatremia, obesity, GHD, and a number of others. In some cases where adipsia was caused by growths on thirst centers in the brain, surgical removal of the growths was successful in treating adipsia.


Despite the inclusion of all patients with neonatal DI, the number of subjects investigated was small because this complex condition is very rare. No recurrence of hypernatremia was reported during the subsequent follow-up of these patients.

Nat Neurosci ; Contribution of magnetic resonance imaging in non-tumoral hypopituitarism in children. Hypernattremia D is the least commonly diagnosed and researched type of adipsia. ADH secretion is one of the primary mechanisms by which sodium and osmolar homeostasis are regulated, ADH is also secreted when there are small increases in serum osmolality. Figure A is modified from These vulnerable patients have high rates of comorbidity and require aipsic monitoring.

The peripheral portion, however, is positioned to respond to factors in cerebrospinal fluid CSFsuch as sodium Hypothalamic hpernatremia without demonstrable structural lesion.

People affected by diabetes insipidus have the option of using the intranasal or oral hormone desmopressin acetate DDAVPwhich is molecularly similar enough to vasopressin to perform its function.
