Degenerative Jargon Aphasia: Unusual Progression of Logopenic/Phonological Progressive Aphasia?
Primary progressive aphasia (PPA) corresponds to the gradual degeneration of language which can occur as nonfluent/agrammatic PPA, semantic variant PPA or logopenic variant PPA. We describe the clinical evolution of a patient with PPA presenting jargon aphasia as a late feature. At the onset of the disease (ten years ago) the patient showed anomia and executive deficits, followed later on by ph...
متن کاملNeural Correlates of Verbal Episodic Memory and Lexical Retrieval in Logopenic Variant Primary Progressive Aphasia
Objective: Logopenic variant primary progressive aphasia (lvPPA) is commonly associated with Alzheimer's disease (AD) pathology. But lvPPA patients display different cognitive and anatomical profile from the common clinical AD patients, whose verbal episodic memory is primarily affected. Reports of verbal episodic memory difficulty in lvPPA are inconsistent, and we hypothesized that their lexic...
متن کاملProgression of logopenic variant primary progressive aphasia to apraxia and semantic memory deficits
BACKGROUND Due to the nature of neurodegenerative disorders, patients with primary progressive aphasia develop cognitive impairment other than aphasia as the disorder progresses. The progression of logopenic variant primary progressive aphasia (lvPPA), however, has not been well described. In particular, praxic disorders and semantic memory deficits have rarely been reported. CASE PRESENTATIO...
متن کاملPhonological short term memory in conduction aphasia
Background: Within cognitive neuropsychological models, conduction aphasia has been conceptualized as a phonological buffer deficit. It may affect the output buffer, the input buffer, or both. The phonological output buffer is a short-term storage, responsible for the short-term maintenance of phonological units until their articulation, as well as for phonological and morphological composition...
متن کاملCreutzfeldt-Jakob disease revealed by a logopenic variant of primary progressive aphasia.
Logopenic aphasia, mainly characterized by word anomia, sentence and phrase comprehension difficulties secondary to phonological loop deficits but relatively preserved single word comprehension and no agrammatism, is one of the 3 main variants of primary progressive aphasia (PPA). We describe the first case of PPA that fulfilled clinical criteria of logopenic aphasia but showed abnormal DWI hyp...
