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 ...
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 ...
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 ...
Connected speech features from picture description in Alzheimer's disease: a systematic review
(IOS Press, 2018-08-21)
The language changes that occur over the course of Alzheimer’s disease (AD) can impact communication abilities and have profound functional consequences. Picture description tasks can be used to approximate everyday ...
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 ...
Comprehension of concrete and abstract words in semantic variant primary progressive aphasia and Alzheimer’s disease: a behavioral and neuroimaging study
(2017-04-20)
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 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 ...
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 ...
Longitudinal gray matter contraction in three variants of primary progressive aphasia : a tensor-based morphometry study
(Elsevier, 2015-01-22)
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 ...
