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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
