The course of the disease varies with symptoms that range from dementia to complete coma; severe intermittent sympathetic storming with abnormal posturing is often reported in literature. It is presumably secondary to a deficiency of B complex vitamins, specifically thiamine and many patients have clinical improvement after repletion of B vitamins. We present a case of a 35-year-old man who developed MBD secondary to polysubstance misuse without history of alcohol use. His clinical course was complicated by persistent comatose state with autonomic dysfunction. After the administration of high-dose thiamine and vitamin C and E, the patient regained consciousness and was able to follow commands within 48 hours. Furthermore, this case showed recognising brain MRI findings for MBD is a crucial step in disease identification.<\/jats:p>","DOI":"10.1136\/bcr-2021-247852","type":"journal-article","created":{"date-parts":[[2022,4,4]],"date-time":"2022-04-04T12:06:53Z","timestamp":1649074013000},"page":"e247852","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Marchiafava-Bignami disease presenting as reversible coma"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8154-0233","authenticated-orcid":false,"given":"Yixin","family":"Zhang","sequence":"first","affiliation":[{"name":"Internal Medicine, University of Florida College of Medicine - Jacksonville, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaleb","family":"Culpepper","sequence":"additional","affiliation":[{"name":"Neurology, UF Health Jacksonville, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reshmi","family":"Mathew","sequence":"additional","affiliation":[{"name":"Internal Medicine, University of Florida College of Medicine - Jacksonville, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"CruzSaavedra","sequence":"additional","affiliation":[{"name":"Neurology, UF Health Jacksonville, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,4,4]]},"reference":[{"key":"2025082700554210000_15.4.e247852.1","unstructured":"Tian TY , Pescador Ruschel MA , Park S , et al .
