Discourse in primary progressive aphasia: Longitudinal changes and neural correlates

2025-05-27

Abstract excerpt

<h4>Background</h4> Primary progressive aphasia (PPA) is a neurodegenerative brain condition with three variants - nonfluent (nfvPPA), logopenic (lvPPA), semantic (svPPA). At onset, nfvPPA shows atrophy in left inferior frontal gyrus with grammatical impairment; lvPPA involves left temporo-parietal junction, affecting phonological processing; and svPPA impacts left anterior temporal pole, impairing semantic proces...
