Syntax and conversation in aphasia. A strategic restrictive use of Spanish and Catalan connector QUE by aphasic speakers.

2009

Oral conversational data are deemed to be a relevant empirical source when it comes to formulating and supporting hypotheses about cognitive processes involved in aphasic linguistic production. With this assumption in mind, free conversational uses of the Spanish and Catalan connector QUE by fluent and non-fluent aphasic speakers are examined by contrasting them with normal speakers' (i.e. conversational partners') productions. Strictly ungrammatical uses in aphasic speakers are practically non-existent in free conversation. Nevertheless, this data permits one to characterize the aphasic production of the morpheme QUE as restrictive--to different degrees--with respect to normal production. …

The Selective Impairment of Phonological Processing in Speech Production

2000

We report the naming performance of a patient (DM) with a fluent progressive aphasia who made phonological errors in all language production tasks. The pattern of errors in naming was strikingly clear: DM made very many phonological errors that resulted almost always in nonword responses. The complete absence of semantic errors and the very low ratio of formal errors relative to nonword errors (1.6:30.3) in DM's performance are discussed in the context of recent claims about the nature of naming deficits in fluent aphasics. We argue that DM's performance makes highly improbable the claim that fluent aphasia results from global lesions affecting all levels of the lexical access system equall…

“My Mind Is Doing It All”

2015

Objective: To study whether pressure of speech in jargon aphasia arises out of disturbances to core language or executive processes, or at the intersection of conceptual preparation. Background: Conceptual preparation mechanisms for speech have not been well studied. Several mechanisms have been proposed for jargon aphasia, a fluent, well-articulated, logorrheic propositional speech that is almost incomprehensible. Methods: We studied the vast quantity of jargon speech produced by patient J.A., who had suffered an infarct after the clipping of a middle cerebral artery aneurysm. We gave J.A. baseline cognitive tests and experimental word-and sentencegeneration tasks that we had designed for …

LE SEQUENZE T2-FLAIR E DWI NELLA DIAGNOSI DI ENCEFALOPATIA DI WERNICKE NON ALCOOL- CORRELATA

2013

SCOPO DEL LAVORO Valutare l’accuratezza delle immagini T2-FLAIR e DWI nello studio delle lesioni caratteristiche dell’Encefalopatia di Wernicke. MATERIALI E METODI Studio effettuato su donna di 56 anni, affetta da Encefalopatia di Wernicke non alcool-correlata. Nel Dicembre 2011 la paziente è stata sottoposta ad esame RM, utilizzando un tomografo operante a 1,5 T con acquisizione di scansioni sui piani assiale, sagittale e coronale in tecnica Spin-Echo (SE), Fast Spin-Echo (FSE), Fluid Attenuated Inversion Recovery (FLAIR) e Diffusion Weighted Imaging (DWI), con sequenze T1 e T2 pesate. L’esame è stato completato dopo infusione e.v. di m.d.c. paramagnetico. L’indagine mostrava la presenza…

Magnetic resonance imaging in the assessment of brain involvement in alcoholic and nonalcoholic Wernicke's encephalopathy

2017

AIM To present the typical and atypical magnetic resonance (MR) imaging findings of alcoholic and non-alcoholic Wernicke’s encephalopathy. METHODS This study included 7 patients with Wernicke’s encephalopathy (2 men, 5 women; mean age, 52.3 years) that underwent brain MR examination between January 2012 and March 2016 in a single institution. Three patients were alcoholics and 4 patients were non-alcoholics. MR protocol included a T2-weighted sequence, a fluid attenuation inversion recovery (FLAIR) sequence, a diffusion-weighted sequence (b = 0 and 1000 s/mm2), and a contrast-enhanced MR sequence. All MR images were retrospectively reviewed at baseline and follow-up by two radiologists. RES…
