We report the results of a study designed to prospectively define the natural history of post-traumatic diabetes insipidus (DI) and syndrome of inappropriate antidiuretic hormone secretion (SIADH) using standard reliable methodology.<\/jats:p><jats:p><jats:italic>Design and methods<\/jats:italic>: 50 consecutive patients with severe or moderate TBI (initial Glasgow Coma Scale (GCS) score 3\/15\u201313\/15) were prospectively studied on three occasions: at the acute phase and at 6 months and at 12 months following TBI. In the acute phase, DI was diagnosed either by the presence of hypernatraemia in association with hypotonic polyuria or by the water-deprivation test (WDT) and, at 6 and 12 months by the WDT in all patients. Normative data on response to the WDT were obtained from healthy matched volunteers. Functional outcome was assessed using the Glasgow Outcome Scale (GOS).<\/jats:p><jats:p><jats:italic>Results<\/jats:italic>: 13 patients (26%) had DI in the acute post-TBI phase, of whom nine patients recovered by 6 months and one additional patient recovered by 12 months. Of the remaining three patients with permanent DI, two had partial vasopressin deficiency. Acute-phase peak plasma osmolality correlated negatively with the initial GCS scores (<jats:italic>r<\/jats:italic>= \u22120.39,<jats:italic>P<\/jats:italic>= 0.005) and with the GOS scores (<jats:italic>r<\/jats:italic>= \u22120.45,<jats:italic>P<\/jats:italic>= 0.001). Seven patients had SIADH in the acute phase of TBI but none did at 6 or 12 months. No new cases of DI or SIADH were noted after the acute phase.<\/jats:p><jats:p><jats:italic>Conclusion<\/jats:italic>: This prospective study shows that posterior pituitary dysfunction is common following TBI. Most cases recover completely but there is an appreciable frequency of long-term DI which can be subtle and should be recognized and managed appropriately.<\/jats:p>","DOI":"10.1530\/eje.1.01861","type":"journal-article","created":{"date-parts":[[2005,3,8]],"date-time":"2005-03-08T21:13:39Z","timestamp":1110316419000},"page":"371-377","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-1","source":"Crossref","is-referenced-by-count":138,"title":["The natural history of post-traumatic neurohypophysial dysfunction"],"prefix":"10.1093","volume":"152","author":[{"given":"Amar","family":"Agha","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Sherlock","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack","family":"Phillips","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William","family":"Tormey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher J","family":"Thompson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","reference":[{"key":"2_25748140","first-page":"340","volume":"27","year":"1998","journal-title":"ANNALS OF THE ACADEMY OF MEDICINE OF SINGAPORE"},{"issue":"6","key":"3_18234010","doi-asserted-by":"crossref","first-page":"500","DOI":"10.1177\/000313480407000607","volume":"70","author":"Boughey","year":"2004","journal-title":"The American surgeon","ISSN":"https:\/\/id.crossref.org\/issn\/0003-1348","issn-type":"print"},{"issue":"3","key":"4_13568883","doi-asserted-by":"crossref","first-page":"456","DOI":"10.3171\/jns.1985.63.3.0456","volume":"63","author":"Hadani","year":"1985","journal-title":"Journal of neurosurgery","ISSN":"https:\/\/id.crossref.org\/issn\/0022-3085","issn-type":"print"},{"issue":"10","key":"5_17267470","doi-asserted-by":"publisher","first-page":"788","DOI":"10.1097\/00002060-200210000-00013","volume":"81","author":"Alaca","year":"2002","journal-title":"American journal of physical medicine &amp;
