Teaching NeuroImages: Nonfluent variant primary progressive aphasia
A 66-year-old woman presented with 4 years of progressive speech difficulty. She had nonfluent speech with phonemic errors but intact single-word comprehension and object knowledge. Her grammar was impaired in both speech and writing, and she exhibited orofacial apraxia. A clinico-radiologic (see figure) diagnosis of nonfluent variant primary progressive aphasia was made. Nonfluent variant prim...
متن کاملGrammatical comprehension deficits in non-fluent/agrammatic primary progressive aphasia.
IMPORTANCE Grammatical comprehension difficulty is an essential supporting feature of the non-fluent/agrammatic variant of primary progressive aphasia (naPPA), but well-controlled clinical measures of grammatical comprehension are unavailable. OBJECTIVE To develop a measure of grammatical comprehension and examine this comparatively in PPA variants and behavioural-variant frontotemporal degen...
متن کاملNeural correlates of syntactic processing in the nonfluent variant of primary progressive aphasia.
The left posterior inferior frontal cortex (IFC) is important for syntactic processing, and has been shown in many functional imaging studies to be differentially recruited for the processing of syntactically complex sentences relative to simpler ones. In the nonfluent variant of primary progressive aphasia (PPA), degeneration of the posterior IFC is associated with expressive and receptive agr...
متن کاملLack of Frank Agrammatism in the Nonfluent Agrammatic Variant of Primary Progressive Aphasia
BACKGROUND/AIMS Frank agrammatism, defined as the omission and/or substitution of grammatical morphemes with associated grammatical errors, is variably reported in patients with nonfluent variant primary progressive aphasia (nfPPA). This study addressed whether frank agrammatism is typical in agrammatic nfPPA patients when this feature is not required for diagnosis. METHOD We assessed grammat...
متن کاملTreatment for Apraxia of Speech in Nonfluent Variant Primary Progressive Aphasia
There is a growing body of literature examining the utility of behavioral treatment in primary progressive aphasia (PPA). There are, however, no studies exploring treatment approaches to improve speech production in individuals with apraxia of speech (AOS) associated with the nonfluent variant of PPA. The purpose of this study was to examine a novel approach to treatment of AOS in nonfluent PPA...
