She was subsequently admitted to our hospital because of impaired consciousness and generalized tonic-clonic seizures. Severe hyponatremia and increased urinary sodium excretion were noted, leading to a diagnosis of syndrome of inappropriate antidiuresis (SIAD), being suspected Guillain-Barr\u00e9 syndrome (GBS) as the cause. However, she did not present with muscle weakness or deep sensory impairment, whereas orthostatic hypotension and the results of 123-I-meta-iodobenzylguanidine scintigraphy suggested the presence of autonomic dysfunction. We diagnosed her with acute autonomic and sensory neuropathy (AASN) rather than GBS. AASN is a neurological disorder closely related to GBS, characterized by an acute onset of sensory and autonomic dysfunction without motor impairment. Because AASN may rapidly progress to a severe form, it is important to recognize that AASN is a contributing cause of SIAD and to manage it appropriately at an early stage.<\/jats:p>","DOI":"10.1210\/jcemcr\/luaf299","type":"journal-article","created":{"date-parts":[[2025,11,20]],"date-time":"2025-11-20T13:11:53Z","timestamp":1763644313000},"source":"Crossref","is-referenced-by-count":0,"title":["Acute Autonomic Sensory Neuropathy Causing Severe Hyponatremia: A Rare Cause of Syndrome of Inappropriate Antidiuresis"],"prefix":"10.1210","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8533-0264","authenticated-orcid":false,"given":"Tatsuo","family":"Ogawa","sequence":"first","affiliation":[{"name":"Center for Diabetes, Endocrinology and Metabolism, Shizuoka General Hospital , Shizuoka 420-8527 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rieko","family":"Kosugi","sequence":"additional","affiliation":[{"name":"Center for Diabetes, Endocrinology and Metabolism, Shizuoka General Hospital , Shizuoka 420-8527 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akinobu","family":"Hori","sequence":"additional","affiliation":[{"name":"Department of Neurology, Graduate School of Medicine and Faculty of Medicine, Kyoto University , Kyoto 606-8507 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masato","family":"Kotani","sequence":"additional","affiliation":[{"name":"Center for Diabetes, Endocrinology and Metabolism, Shizuoka General Hospital , Shizuoka 420-8527 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuhide","family":"Inoue","sequence":"additional","affiliation":[{"name":"Center for Diabetes, Endocrinology and Metabolism, Shizuoka General Hospital , Shizuoka 420-8527 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Ariyasu","sequence":"additional","affiliation":[{"name":"Center for Diabetes, Endocrinology and Metabolism, Shizuoka General Hospital , Shizuoka 420-8527 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"80","published-online":{"date-parts":[[2025,12,23]]},"reference":[{"issue":"5","key":"2025122304293966400_luaf299-B1","doi-asserted-by":"crossref","first-page":"537.e9","DOI":"10.1016\/j.amjmed.2015.11.005","article-title":"Diagnosing and treating the syndrome of inappropriate antidiuretic hormone secretion","volume":"129","author":"Verbalis","year":"2016","journal-title":"Am J Med"},{"issue":"6","key":"2025122304293966400_luaf299-B2","doi-asserted-by":"crossref","first-page":"772","DOI":"10.1053\/j.ajkd.2017.12.002","article-title":"Rapidity of correction of hyponatremia due to syndrome of inappropriate secretion of antidiuretic hormone following tolvaptan","volume":"71","author":"Morris","year":"2018","journal-title":"Am J Kidney Dis"},{"issue":"3","key":"2025122304293966400_luaf299-B3","doi-asserted-by":"crossref","first-page":"G1","DOI":"10.1530\/EJE-13-1020","article-title":"Clinical practice guideline on diagnosis and treatment of hyponatraemia","volume":"170","author":"Spasovski","year":"2014","journal-title":"Eur J Endocrinol"},{"issue":"5","key":"2025122304293966400_luaf299-B4","doi-asserted-by":"crossref","first-page":"819","DOI":"10.1210\/endrev\/bnad010","article-title":"Syndrome of inappropriate antidiuresis: from pathophysiology to management","volume":"44","author":"Warren","year":"2023","journal-title":"Endocr Rev"},{"issue":"4","key":"2025122304293966400_luaf299-B5","doi-asserted-by":"crossref","first-page":"441","DOI":"10.1002\/ana.410080419","article-title":"Acute autonomic and sensory neuropathy","volume":"8","author":"Colan","year":"1980","journal-title":"Ann Neurol"},{"issue":"10","key":"2025122304293966400_luaf299-B6","doi-asserted-by":"crossref","first-page":"2881","DOI":"10.1093\/brain\/awq214","article-title":"Clinicopathological features of acute autonomic and sensory neuropathy","volume":"133","author":"Koike","year":"2010","journal-title":"Brain"},{"issue":"1","key":"2025122304293966400_luaf299-B7","doi-asserted-by":"crossref","first-page":"98","DOI":"10.1136\/jnnp-2012-302833","article-title":"The spectrum of immune-mediated autonomic neuropathies: insights from the clinicopathological features","volume":"84","author":"Koike","year":"2013","journal-title":"J Neurol Neurosurg Psychiatry"},{"issue":"5","key":"2025122304293966400_luaf299-B8","doi-asserted-by":"crossref","first-page":"530","DOI":"10.1001\/archneur.1967.00470290084011","article-title":"Hyponatremia in acute polyneuropathy.
