Abstract

GONZALEZ V, Rafael et al. Fluent progressive aphasia: A form of inicial presentation of semantic dementia?. Rev. chil. neuro-psiquiatr. [online]. 2007, vol.45, n.1, pp.43-50. ISSN 0717-9227.  http://dx.doi.org/10.4067/S0717-92272007000100008.

We report a 57-year-old man presenting with progressive fluent aphasia and behaviour disorder, with no visual semantic loss, visual agnosia, lexical agraphia, nor alexia. We include in this report the brain images, and we discuss the borders between fluent progressive aphasia and semantic dementia. We conclude that fluent progressive aphasia may be the first stage of semantic dementia, noting that the neuropathology of progressive fluent aphasia usually corresponds to frontotemporal lobar degeneration, with or without Tau protein inclusions, as in Alzheimer's Disease or corticobasal degeneration

Keywords : Progressive aphasia; semantic dementia; fronto-temporal dementia.
