Neurol."],"abstract":"<jats:p>Beyond canonical deficits in social cognition and interpersonal conduct, behavioral variant frontotemporal dementia (bvFTD) involves language difficulties in a substantial proportion of cases. However, since most evidence comes from high-income countries, the scope and relevance of language deficits in Latin American bvFTD samples remain poorly understood. As a first step toward reversing this scenario, we review studies reporting language measures in Latin American bvFTD cohorts relative to other groups. We identified 24 papers meeting systematic criteria, mainly targeting phonemic and semantic fluency, naming, semantic processing, and comprehension skills. The evidence shows widespread impairments in these domains, often related to overall cognitive disturbances. Some of these deficits may be as severe as in other diseases where they are more widely acknowledged, such as Alzheimer's disease. Considering the prevalence and informativeness of language deficits in bvFTD patients from other world regions, the need arises for more systematic research in Latin America, ideally spanning multiple domains, in diverse languages and dialects, with validated batteries. We outline key challenges and pathways of progress in this direction, laying the ground for a new regional research agenda on the disorder.<\/jats:p>","DOI":"10.3389\/fneur.2021.702770","type":"journal-article","created":{"date-parts":[[2021,8,10]],"date-time":"2021-08-10T07:35:04Z","timestamp":1628580904000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Language in Behavioral Variant Frontotemporal Dementia: Another Stone to Be Turned in Latin America"],"prefix":"10.3389","volume":"12","author":[{"given":"Amandine","family":"Geraudie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariano","family":"D\u00edaz Rivera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maxime","family":"Montembeault","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adolfo M.","family":"Garc\u00eda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,8,10]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"221","DOI":"10.3389\/fnagi.2017.00221","article-title":"Dementia in Latin America: epidemiological evidence and implications for public policy","volume":"9","author":"Custodio","year":"2017","journal-title":"Front Aging Neurosci."},{"key":"B2","doi-asserted-by":"crossref","DOI":"10.1016\/S1474-4422(10)70299-4","article-title":"Behavioural-variant frontotemporal dementia: diagnosis, clinical staging, and management","volume-title":"Lancet Neurol.","author":"Piguet","year":"2011"},{"key":"B3","doi-asserted-by":"crossref","DOI":"10.1093\/brain\/awr179","article-title":"Sensitivity of revised diagnostic criteria for the behavioural variant of frontotemporal dementia","volume-title":"Brain J Neurol.","author":"Rascovsky","year":"2011"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1080\/17470919.2016.1245214","article-title":"Social neuroscience: undoing the schism between neurology and psychiatry","volume":"13","author":"Ib\u00e1\u00f1ez","year":"2018","journal-title":"Soc Neurosci."},{"key":"B5","doi-asserted-by":"crossref","DOI":"10.1136\/jnnp-2015-310697","article-title":"The behavioural variant frontotemporal dementia (bvFTD) syndrome in psychiatry","volume-title":"J Neurol Neurosurg Psychiatry.","author":"Lanata","year":"2016"},{"key":"B6","doi-asserted-by":"crossref","DOI":"10.2217\/nmt.14.34","article-title":"Frontotemporal dementia: Diagnosis, deficits and management","volume-title":"Neurodegen Dis Manag.","author":"Bott","year":"2014"},{"key":"B7","doi-asserted-by":"crossref","DOI":"10.3109\/09540261.2013.763340","article-title":"Language, executive function and social cognition in the diagnosis of frontotemporal dementia syndromes","volume-title":"Int Rev Psychiatry (Abingdon, England).","author":"Harciarek","year":"2013"},{"key":"B8","doi-asserted-by":"crossref","DOI":"10.1590\/S1980-57642013DN70100003","article-title":"Behavioural-variant frontotemporal dementia: an update","volume-title":"Dementia Neuropsychol.","author":"Piguet","year":"2013"},{"key":"B9","article-title":"Neurodegenerative disorders of speech and language: non-language-dominant disease","author":"Garcia","year":"2020"},{"key":"B10","doi-asserted-by":"crossref","DOI":"10.1136\/jnnp-2017-315667","article-title":"Examining the language and behavioural profile in FTD and ALS-FTD","volume-title":"J Neurol Neurosurg Psychiatry.","author":"Saxon","year":"2017"},{"key":"B11","doi-asserted-by":"crossref","DOI":"10.1159\/000444848","article-title":"Co-occurrence of language and behavioural change in frontotemporal lobar degeneration","volume-title":"Dementia Geriatr Cogn Disord Extra.","author":"Harris","year":"2016"},{"key":"B12","doi-asserted-by":"crossref","DOI":"10.1017\/S1355617718001005","article-title":"Cognitive indicators of preclinical behavioral variant frontotemporal dementia in MAPT carriers","volume-title":"J Int Neuropsychol Soc JINS","author":"Cheran","year":"2019"},{"key":"B13","doi-asserted-by":"crossref","DOI":"10.3233\/JAD-150806","article-title":"The language profile of behavioral variant frontotemporal dementia","volume-title":"J Alzheimers Dis","author":"Hardy","year":"2016"},{"key":"B14","doi-asserted-by":"publisher","first-page":"f4827","DOI":"10.1136\/bmj.f4827","article-title":"Clinical review.
