Comprehension of concrete and abstract words in semantic variant primary progressive aphasia and Alzheimer’s disease: a behavioral and neuroimaging study
The aim of this study was to investigate the comprehension of concrete, abstract and abstract emotional words in semantic variant primary progressive aphasia (svPPA), Alzheimer’s disease (AD), and healthy elderly adults ...
The neural correlates of verbal and nonverbal semantic processing deficits in neurodegenerative disease
(Lippincott, Williams & Wilkins, 2009)
Objective—To investigate the neural correlates of verbal and non-verbal semantic processing in neurodegenerative disease. Background—Semantic memory is often impaired in neurodegenerative disease. Neuropsychological and ...
The challenge of mapping the human connectome based on diffusion tractography
(Nature research, 2017-11-07)
Tractography based on non-invasive diffusion imaging is central to the study of human brain connectivity. To date, the approach has not been systematically validated in ground truth studies. Based on a simulated human brain ...
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 ...
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?
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 ...
Atrophy, metabolism and cognition in posterior cortical atrophy spectrum based on AD CSF biomarkers
Introduction In vivo clinical, anatomical and metabolic differences between posterior cortical atrophy (PCA) patients presenting with different Alzheimer's disease (AD) cerebrospinal fluid (CSF) biomarkers profiles are ...
La sémantique, la lecture de mots irréguliers et les lobes temporaux antérieurs
Semantics, irregular word reading and the anterior temporal lobes
(Ortho édition, 2014)
Dans cette recension des écrits nous présentons les résultats d’études comportementales et de neuroimagerie mettant en rapport la sémantique et la lecture de mots irréguliers, ainsi que la sémantique et les lobes temporaux ...
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 ...
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 ...
