Acute cerebellar ataxia is a syndrome that occurs in less than 72 hours, in previously healthy subjects. Acute ataxia usually results in hospitalization and extensive laboratory investigation. Clinicians are often faced with decisions on the extent and timing of the initial screening tests, particularly to detect treatable causes. The main group of diseases that may cause acute ataxias discussed in this article are: stroke, infectious, toxic, immune-mediated, paraneoplastic, vitamin deficiency, structural lesions and metabolic diseases. This review focuses on the etiologic and diagnostic considerations for acute ataxia.<\/jats:p>","DOI":"10.1590\/0004-282x20190020","type":"journal-article","created":{"date-parts":[[2019,4,3]],"date-time":"2019-04-03T19:35:01Z","timestamp":1554320101000},"page":"184-193","source":"Crossref","is-referenced-by-count":65,"title":["Acute cerebellar ataxia: differential diagnosis and clinical approach"],"prefix":"10.1590","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1672-8894","authenticated-orcid":false,"given":"Jos\u00e9 Luiz","family":"Pedroso","sequence":"first","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6145-9868","authenticated-orcid":false,"given":"Thiago Cardoso","family":"Vale","sequence":"additional","affiliation":[{"name":"Universidade Federal de Juiz de Fora,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9186-9243","authenticated-orcid":false,"given":"Pedro","family":"Braga-Neto","sequence":"additional","affiliation":[{"name":"Universidade Federal do Cear\u00e1,  Brasil; Universidade Estadual do Cear\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6309-9077","authenticated-orcid":false,"given":"L\u00edvia Almeida","family":"Dutra","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brasil; Hospital Israelita Albert Einstein,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0898-2419","authenticated-orcid":false,"given":"Marcondes Cavalcante","family":"Fran\u00e7a Jr","sequence":"additional","affiliation":[{"name":"Universidade Estadual de Campinas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2305-1073","authenticated-orcid":false,"given":"H\u00e9lio A.
