Clinical, anatomical and pathological features in the three variants of primary progressive aphasia : a review
(Frontiers media, 2018-08-21)
Primary progressive aphasias (PPA) are neurodegenerative diseases clinically characterized by an early and relatively isolated language impairment. Three main clinical variants, namely the nonfluent/agrammatic variant ...
The anatomy of category-specific object naming in neurodegenerative diseases
(Massachusetts Institute of Technology Press, 2006)
Neuropsychological studies suggest that knowledge about living and nonliving objects is processed in separate brain regions. However, lesion and functional neuroimaging studies have implicated different areas. To address ...
Music recognition in frontotemporal lobar degeneration and Alzheimer disease
(Lippincott, Williams & Wilkins, 2011-06)
Objective—To compare music recognition in patients with frontotemporal dementia, semantic dementia, Alzheimer disease, and controls and to evaluate the relationship between music recognition and brain volume. Backgrou ...
Anatomical correlates of early mutism in progressive nonfluent aphasia
(American Academy of Neurology, 2006)
Patients with progressive nonfluent aphasia (PNFA) can become mute early in the course of the disease. Voxel-based morphometry showed that PNFA is associated with left anterior insula and inferior frontal atrophy. In ...
Longitudinal gray matter contraction in three variants of primary progressive aphasia : a tensor-based morphometry study
The present study investigated the pattern of longitudinal changes in cognition and anatomy in three variants of primary progressive aphasia (PPA). Eight patients with the non-fluent variant of PPA (nfvPPA), 13 patients ...
The logopenic/phonological variant of primary progressive aphasia
(American Academy of Neurology, 2008)
Objective: 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 ...
