Electrophysiology of object naming in primary progressive aphasia.
Primary progressive aphasia (PPA), a selective neurodegeneration of the language network, frequently causes object naming impairments. We examined the N400 event-related potential (ERP) to explore interactions between object recognition and word processing in 20 PPA patients and 15 controls. Participants viewed photographs of objects, each followed by a word that was either a match to the objec...
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 کاملInhibitory Control Predicts Grammatical Ability
We present evidence that individual variation in grammatical ability can be predicted by individual variation in inhibitory control. We tested 81 5-year-olds using two classic tests from linguistics and psychology (Past Tense and the Stroop). Inhibitory control was a better predicator of grammatical ability than either vocabulary or age. Our explanation is that giving the correct response in bo...
متن کاملPrefrontal cortex rTMS enhances action naming in progressive non-fluent aphasia.
BACKGROUND AND PURPOSE Progressive non-fluent aphasia (PNFA) is a neurodegenerative disorder that is characterized by non-fluent speech with naming impairment and grammatical errors. It has been recently demonstrated that repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) improves action naming in healthy subjects and in subjects with Alzheimer's...
متن کاملModality-specific deterioration in naming verbs in nonfluent primary progressive aphasia.
A longitudinal study of oral and written naming and comprehension of nouns and verbs in an individual (M. M. L.) with nonfluent primary progressive aphasia (PPA) is reported. M. M. L. showed progressive deterioration of oral naming of verbs well before deterioration of written naming of verbs and before deterioration of oral or written naming of nouns. Her comprehension of both nouns and verbs ...
