Speech disorders in primary progressive aphasia (PPA)

Journal of Education, Health and Sport, 2022
Introduction : Primary progressive aphasia (PPA) is a group of neurodegenerative disorders whose main feature is speech and language dysfunction. There are three main forms of PPA - non-fluent variant - agrammatic (nfvPPA), semantic variant (svPPA) and ...

Network anatomy in logopenic variant of primary progressive aphasia

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.

Pattern of cortical thinning in logopenic progressive aphasia patients in Thailand [PDF]

BMC Neurology, 2020
Abstract Background Logopenic progressive aphasia (LPA) is an uncommon neurodegenerative disorder primarily characterized by word-finding difficulties and sentence repetition impairment. Prominent cortical atrophy around left temporo-parietal junction (TPJ) is a classical imaging feature of LPA.

Structural, Microstructural, and Metabolic Alterations in Primary Progressive Aphasia Variants

Frontiers in Neurology, 2018
Neuroimaging studies have described the brain alterations in primary progressive aphasia (PPA) variants (semantic, logopenic, nonfluent/agrammatic). However, few studies combined T1, FDG-PET, and diffusion MRI techniques to study atrophy, hypometabolism,

Neuroanatomical correlates of phonologic errors in logopenic progressive aphasia

Brain and Language, 2020
While phonologic errors may be one of the salient features of the logopenic variant of primary progressive aphasia (lvPPA), sparse data are available on their neuroimaging correlates. The purpose of this study was to identify brain regions associated with different types of phonologic errors across several tasks for participants with lvPPA ...

Retained capacity for perceptual learning of degraded speech in primary progressive aphasia and Alzheimer’s disease

Alzheimer’s Research & Therapy, 2018
Background Processing of degraded speech is a promising model for understanding communication under challenging listening conditions, core auditory deficits and residual capacity for perceptual learning and cerebral plasticity in major dementias. Methods

Breakdowns in Informativeness of Naturalistic Speech Production in Primary Progressive Aphasia

Brain Sciences, 2021
“Functional communication” refers to an individual’s ability to communicate effectively in his or her everyday environment, and thus is a paramount skill to monitor and target therapeutically in people with aphasia.
