Cross-sectional analysis of picture descriptions of healthy young and older adults
(Université de Montréal, 2019)
It is poorly understood whether and how normal aging affects different aspects of connected speech
production, such as fluency, informativity, efficiency, and vocabulary use. The present study crosssectionally investigates ...
Functional network and structural connections involved in picture naming
(Elsevier, 2022-06-13)
We mapped the left hemisphere cortical regions and fiber bundles involved in picture naming in adults by integrating task-based fMRI with dMRI tractography.
We showed that a ventral pathway that “maps image and sound ...
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 ...
Atrophy in Alzheimer’s disease and semantic dementia : an ALE meta-analysis of voxel-based morphometry studies
(IOS Press, 2016)
Background/Objectives: Alzheimer’s disease (AD) and semantic dementia (SD) have distinct episodic memory profiles
despite the hippocampal atrophy that characterizes both diseases. The aim of this study was to delineate ...
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
...
Functional changes in the cortical semantic network in amnestic mild cognitive impairment
(American Psychological Association, 2018-05)
Semantic memory impairment has been documented in older individuals with amnestic
Mild cognitive impairment (aMCI), who are at risk of developing Alzheimer’s disease (AD), yet
little is known about the neural basis of ...
Rule violation errors are associated with right lateral prefrontal cortex atrophy in neurodegenerative disease
(Cambridge University Press, 2009)
Good cognitive performance requires adherence to rules specific to the task at hand. Patients with neurological disease often make rule violation errors, but the anatomical basis for rule violation during cognitive testing ...
Single and Multiple Domain Amnestic MCI: two sides of the same coin?
Single- and multiple-domain amnestic mild cognitive impairment: two sides of the same coin?
(2009)
Background. Amnestic Mild Cognitive Impairment (aMCI) is considered a transition
stage between normal aging and Alzheimer's disease (AD). Two main clinical subtypes
of aMCI have been identified: 1) aMCI single domain ...
A MEG study of the neural substrates of semantic processing in semantic variant primary progressive aphasia
(Taylor & Francis, 2019-07-01)
Despite a well-documented pattern of semantic memory (SM) impairment, the patterns of brain
activation during semantic processing in svPPA still remain poorly understood. The current study
aimed to investigate the neural ...
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 ...
