Impaired phonemic discrimination in logopenic variant primary progressive aphasia [PDF]
Annals of Clinical and Translational Neurology, 2020 Logopenic variant primary progressive aphasia (lvPPA) is the least well defined of the major primary progressive aphasia (PPA) syndromes. We assessed phoneme discrimination in patients with PPA (semantic, nonfluent/agrammatic, and logopenic variants) and

Quantitative assessment of grammar in amyloid-negative logopenic aphasia. [PDF]
Brain Lang, 2018 Logopenic primary progressive aphasia (lvPPA) typically results from underlying Alzheimer's disease, but subjects have been reported that do not show beta-amyloid (Aβ) deposition. These subjects do not differ on neurological and speech-language testing from Aβ-positive lvPPA, but they impressionistically show increased grammatical deficits.

Logopenic progressive aphasia with neologisms: a case report [PDF]
BMC Neurology, 2019 Background Neologisms are commonly encountered in patients with acute cerebrovascular diseases, particularly in those with Wernicke’s aphasia. However, few studies have investigated primary progressive aphasia with neologisms in neurodegenerative disease.

Degenerative Jargon Aphasia: Unusual Progression of Logopenic/Phonological Progressive Aphasia?
Behavioural Neurology, 2013 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.

J Alzheimers Dis, 2018 Background: Neuropsychological assessment can add essential information to the characterization of individuals presenting with the logopenic variant of primary progressive aphasia (lvPPA). Objective: This study examined the neuropsychological characteristics of lvPPA patients.

Impaired semantic control in the logopenic variant of primary progressive aphasia. [PDF]
Brain CommunicationsWe investigated semantic cognition in the logopenic variant of primary progressive aphasia, including (i) the status of verbal and non-verbal semantic performance; and (ii) whether the semantic deficit reflects impaired semantic control.
