Syntactic and thematic components of sentence processing in progressive nonfluent aphasia and nonaphasic frontotemporal dementia.
We used an online word-monitoring paradigm to examine sentence processing in healthy seniors and frontotemporal dementia patients with progressive nonfluent aphasia (PNFA) or a nonaphasic disorder of social and executive functioning (SOC/EXEC). Healthy seniors were sensitive to morphosyntactic, major grammatical subcategory, and selection restriction violations in a sentence. PNFA patients were...
متن کاملSentence comprehension and voxel-based morphometry in progressive nonfluent aphasia, semantic dementia, and nonaphasic frontotemporal dementia.
To investigate the basis for impaired sentence comprehension in patients with frontotemporal dementia (FTD) we assessed grammatical comprehension and verbal working memory in 88 patients with three distinct presentations: progressive nonfluent aphasia (PNFA), semantic dementia (SD), and nonaphasic patients with a disorder of social comportment and executive processing (SOC/EXEC). We related sen...
متن کاملSemantic dementia versus nonfluent progressive aphasia: neuropsychological characterization and differentiation.
BACKGROUND Early progressive nonfluent aphasia (PNFA) may be difficult to differentiate from semantic dementia (SD) in a nonspecialist setting. There are descriptions of the clinical and neuropsychological profiles of patients with PNFA and SD but few systematic comparisons. METHOD We compared the performance of groups with SD (n=27) and PNFA (n=16) with comparable ages, education, disease du...
متن کاملPrimary progressive aphasia: a comparative study of progressive nonfluent aphasia and semantic dementia.
Primary progressive aphasia (PPA), a degenerative disorder, is often misdiagnosed as Alzheimer's disease. Its subtypes, semantic dementia (SD), and progressive nonfluent aphasia (PNFA), are often difficult to differentiate from each other. Our objective was to highlight the differences in the language profiles of patients with SD and PNFA. To bring out these differences, we report two patients ...
متن کاملAssessment of Aphasia in Iranian Patients Suffering From Frontotemporal Dementia
Objective Frontotemporal dementia (FTD) is an uncommon type of dementia. The hallmark feature of FTD is the presentation with aphasia, or behavioral changes which are varies in different subtypes of the disease. We propose a quantitative aphasia test as an additive diagnostic tool for differentiation of FTD subtypes. Method: The study was performed on 20 patients, who were referred to dementia...
