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 ...
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 ...
Atrophy, metabolism and cognition in posterior cortical atrophy spectrum based on AD CSF biomarkers
(Elsevier, 2018-10-10)
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 ...
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 ...
Regional reductions of gray matter volume in familial dyslexia
(American Academy of Neurology, 2004)
An in vivo anatomic study of gray matter volume was performed in a group of familial dyslexic individuals,
using an optimized method of voxel-based morphometry. Focal abnormalities in gray matter volume were observed
bilaterally ...
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 ...
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 ...
Regional brain stem atrophy in idiopathic Parkinson's disease detected by anatomical MRI
(Public Library of Science, 2009-12-10)
Idiopathic Parkinson’s disease (PD) is a neurodegenerative disorder characterized by the dysfunction of dopaminergic
dependent cortico-basal ganglia loops and diagnosed on the basis of motor symptoms (tremors and/or ...
L’utilisation du discours spontané pour le diagnostic précoce de la maladie d’Alzheimer
The use of connected speech in the early diagnosis of Alzheimer's Disease
(John Libbey Eurotext, 2021-10-01)
Le trouble cognitif subjectif (TCS) et le trouble cognitif léger (TCL) font partie des phases préclinique et prodromale de la maladie d’Alzheimer (MA), respectivement, et constituent des facteurs de risque de progression ...
