Direct linkSachs, Alyssa Nicole Yuriko; language impairments – ProQuest LLC, 2023
Background: The most common cause of aphasia is a left middle cerebral artery stroke affecting the left perisylvian region of the brain. The perisylvian region is critical for supporting phonological processing, and damage to this region results in difficulty with retrieving and manipulating speech sounds. The impact of weakened phonology has been…

Jeanne Gallee – ProQuest LLC, 2021
Primary progressive aphasia (PPA) is an acquired neurodegenerative syndrome that has specific and devastating effects on an individual's speech and language ability. Based on a detailed assessment of behavior and cognition, combined with structural neuroimaging data and pathological evidence, PPA is typically classified into three variants: the…

Peer reviewedTetzloff, Katerina A.; Utianski, Rene L.; Duffy, Joseph R.; Clark, Heather M.; Strand, Edythe A.; Josephs, Keith A.; Whitwell, Jennifer L. – Journal of Speech, Language, and Hearing Research, 2018
Purpose: The aims of the study were to assess and compare grammatical deficits in written and spoken language production in subjects with agrammatic primary progressive aphasia (agPPA) and in subjects with agrammatism in the context of dominant apraxia of speech (DAOS) and to investigate neuroanatomical correlates. Method: Eight agPPA and 21 DAOS…

Tschirren, Muriel; Laganaro, Marina; Michel, Patrik; Martory, Marie-Dominique; Di Pietro, Marie; Abutalebi, Jubin; Annoni, Jean-Marie – Brain and Language, 2011
Purpose: Bilingual aphasia generally affects both languages. However, the age of acquisition of the second language (L2) seems to play a role in the anatomo-functional correlation of the syntactical/grammatical processes, thus potentially influencing the L2 syntactic impairment following a stroke. The present study aims to analyze the influence of…

Rohrer, Jonathan D.; Crutch, Sebastian J.; Warrington, Elizabeth K.; Warren, Jason D. – Neuropsychologia, 2010
The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…

Albustanji, Yusuf Mohammed – ProQuest LLC, 2009
Agrammatism is a frequent sequela of Broca's aphasia that manifests itself in omission and/or substitution of the grammatical morphemes in spontaneous and constrained speech. The hierarchical structure of syntactic trees has been proposed as an account for difficulty across grammatical morphemes (e.g., tense, agreement, and negation). Supporting…
