Degenerative Jargon Aphasia: Unusual Progression of Logopenic/Phonological Progressive Aphasia? [PDF]

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.

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

The logopenic/phonological variant of primary progressive aphasia [PDF]

Neurology, 2008
Primary progressive aphasia (PPA) is characterized by isolated decline in language functions. Semantic dementia and progressive nonfluent aphasia are accepted PPA variants. A "logopenic" variant (LPA) has also been proposed, but its cognitive and anatomic profile is less defined.

The Neural Basis of Logopenic Progressive Aphasia

Journal of Alzheimer's Disease, 2012
Logopenic progressive aphasia (LPA) is defined clinically by impairments of naming and sentence repetition. The relationship between these impairments and their neural basis has, however, not yet been determined. We aimed to localize cortical thinning associated with naming and repetition deficits using cortical thickness measurements.

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.

Symptom‐based staging for logopenic variant primary progressive aphasia [PDF]

European Journal of Neurology
AbstractBackground and purposeLogopenic variant primary progressive aphasia (lvPPA) is a major variant presentation of Alzheimer's disease (AD) that signals the importance of communication dysfunction across AD phenotypes. A clinical staging system is lacking for the evolution of AD‐associated communication difficulties that could guide diagnosis and ...

Impaired semantic control in the logopenic variant of primary progressive aphasia [PDF]

Brain Communications
Abstract We investigated semantic cognition in the logopenic variant of primary progressive aphasia (lvPPA), including (i) the status of verbal and non-verbal semantic performance; and (ii) whether the semantic deficit reflects impaired semantic control. Our a priori hypothesis that

Network anatomy in logopenic variant of primary progressive aphasia [PDF]

Human Brain Mapping, 2023
Abstract The logopenic variant of primary progressive aphasia (lvPPA) is a neurodegenerative syndrome characterized linguistically by gradual loss of repetition and naming skills, resulting from left posterior temporal and inferior parietal atrophy.
