Norms of concept familiarity and emotional valence for 3,596 French nouns and their contribution in lexical decision
(Springer, 2018-08-20)
In the last decade, research has shown that word processing is influenced by the lexical and semantic features of words. However, norms for a crucial semantic variable-that is, conceptual familiarity-have not been available ...
Naming unique entities in the semantic variant of primary progressive aphasia and Alzheimer's disease : Towards a better understanding of the semantic impairment
(Elsevier, 2016-12-07)
While the semantic variant of primary progressive aphasia (svPPA) is characterized by a predominant semantic memory impairment, episodic memory impairments are the clinical hallmark of Alzheimer's disease (AD). However, ...
Task-induced functional connectivity of picture naming in healthy aging : the impacts of age and task complexity
(MIT Press, 2020-06-01)
The topological organization of the brain, governed by the capacity of brain regions to synchronize their activity, allows for cost-effective performance during everyday cognitive activity. Functional connectivity is an ...
Posterior cortical atrophy : impact on daily living activities and exploration of a cognitive rehabilitation approach
(Cogent OA, 2019-07-11)
Posterior cortical atrophy (PCA) is a neurodegenerative disease affecting
the posterior region of the brain. Little is known about both the impact of PCA on
functioning and how to support patients on a daily basis. The ...
Altered gray matter structural covariance networks in early stages of Alzheimer's disease
(Oxford University Press, 2015-05-20)
Clinical symptoms observed in Alzheimer's disease (AD) patients may reflect variations within specific large-scale brain networks, modeling AD as a disconnection syndrome. The present magnetic resonance imaging study aims ...
Deformation-based shape analysis of the hippocampus in the semantic variant of primary progressive aphasia and Alzheimer’s disease
(Elsevier, 2020-06-03)
Background
Increasing evidence shows that the semantic variant of primary progressive aphasia (svPPA) is characterized by hippocampal atrophy. However, less is known about disease-related morphological hippocampal changes. ...
Connected speech markers of amyloid burden in primary progressive aphasia
(Elsevier, 2021-10-07)
INTRODUCTION
Positron emission tomography (PET) amyloid imaging has become an important part of the diagnostic workup for patients with primary progressive aphasia (PPA) and uncertain underlying pathology. Here, we employ ...
A methodological scoping review of the integration of fMRI to guide dMRI tractography. What has been done and what can be improved; a 20-year perspective
(Elsevier, 2021-11-13)
Combining MRI modalities is a growing trend in neurosciences. It provides opportunities to investigate the brain architecture supporting cognitive functions. Integrating fMRI activation to guide dMRI tractography offers ...
Evidence of a relation between hippocampal volume, white matter hyperintensities, and cognition in subjective cognitive decline and mild cognitive impairment
(Oxford University Press, 2019-10-26)
Objective: The concepts of mild cognitive impairment (MCI) and subjective cognitive decline (SCD) have been proposed to
identify individuals in the early stages of Alzheimer’s disease (AD), or other neurodegenerative ...
Differential language network functional connectivity alterations in Alzheimer's disease and the semantic variant of primary progressive aphasia
(Elsevier, 2019-04-03)
Patients with Alzheimer's disease (AD) and semantic variant primary progressive aphasia (svPPA) can present with similar language impairments, mainly in naming. It has been hypothesized that these deficits are associated ...
