L'atrophie de l'hippocampe dans la maladie d'Alzheimer et la variante sémantique de l'aphasie primaire progressive
Chapleau, Marianne (2020-12-16)L’augmentation de la prévalence des démences est un problème majeur d’intérêt international. À la différence du vieillissement normal, la démence désigne l’affaiblissement progressif de l’ensemble des fonctions intellectuelles : mémoire, attention, ... -
Atrophy in Alzheimer’s disease and semantic dementia : an ALE meta-analysis of voxel-based morphometry studies
Chapleau, Marianne; Aldebert, Joséphine; Montembeault, Maxime; Brambati, Simona Maria (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 the pattern of gray matter (GM) ... -
Deformation-based shape analysis of the hippocampus in the semantic variant of primary progressive aphasia and Alzheimer’s disease
Chapleau, Marianne; Bedetti, Christophe; Devenyi, Gabriel A.; Sheldon, Signy; Rosen, Howard J.; Miller, Bruce L.; Gorno-Tempini, Maria Luisa; Chakravarty, Mallar M.; Brambati, Simona Maria (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. The goal of the present study ... -
Differential language network functional connectivity alterations in Alzheimer's disease and the semantic variant of primary progressive aphasia
Montembeault, Maxime; Chapleau, Marianne; Jarret, Julien; Boukadi, Mariem; Laforce, Robert Jr.; Wilson, Maximiliano A.; Rouleau, Isabelle; Brambati, Simona Maria (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 with different brain mechanisms ... -
Naming unique entities in the semantic variant of primary progressive aphasia and Alzheimer's disease : Towards a better understanding of the semantic impairment
Montembeault, Maxime; Brambati, Simona Maria; Joubert, Sven; Boukadi, Mariem; Chapleau, Marianne; Laforce, Robert Jr.; Wilson, Maximiliano A.; Macoir, Joël; Rouleau, Isabelle (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, AD patients also present with ... -
The role of the hippocampus in the semantic variant of primary progressive aphasia : a resting‐state fcMRI study
Chapleau, Marianne; Montembeault, Maxime; Boukadi, Mariem; Bedetti, Christophe; Laforce, Robert Jr.; Wilson, Maximiliano A.; Brambati, Simona Maria (Wiley, 2019-09-09)The goal of the study was to determine whether the semantic variant of primary progressive aphasia (svPPA) affects the intrinsic connectivity network anchored to left and right anterior hippocampus, but spares the posterior hippocampus. A resting‐state ... -
Test-retest reliability of diffusion measures extracted along white matter language fiber bundles using HARDI-based tractography
Boukadi, Mariem; Marcotte, Karine; Bedetti, Christophe; Houde, Jean-Christophe; Desautels, Alex; Deslauriers-Gauthier, Samuel; Chapleau, Marianne; Boré, Arnaud; Descoteaux, Maxime; Brambati, Simona Maria (Frontiers media, 2019-01-14)High angular resolution diffusion imaging (HARDI)-based tractography has been increasingly used in longitudinal studies on white matter macro- and micro-structural changes in the language network during language acquisition and in language impairments. ...
