Altered gray matter structural covariance networks in early stages of Alzheimer's disease
Montembeault, Maxime; Rouleau, Isabelle; Provost, Jean-Sébastien; Brambati, Simona Maria (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 to compare the organization ... -
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) ... -
Atrophy, metabolism and cognition in posterior cortical atrophy spectrum based on AD CSF biomarkers
Montembeault, Maxime; Brambati, Simona Maria; Lamari, Foudil; Michon, Agnès; Samri, Dalila; Epelbaum, Stéphane; Lacomblez, Lucette; Lehéricy, Stéphane; Habert, Marie-Odile; Dubois, Bruno; Kas, Aurélie; Migliaccio, Raffaella (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 still unknown. Methods Twenty-seven ... -
Clinical, anatomical and pathological features in the three variants of primary progressive aphasia : a review
Montembeault, Maxime; Brambati, Simona Maria; Gorno-Tempini, Maria Luisa; Migliaccio, Raffaella (Frontiers media, 2018-08-21)Primary progressive aphasias (PPA) are neurodegenerative diseases clinically characterized by an early and relatively isolated language impairment. Three main clinical variants, namely the nonfluent/agrammatic variant (nfvPPA), the semantic variant ... -
Comprehension of concrete and abstract words in semantic variant primary progressive aphasia and Alzheimer’s disease: a behavioral and neuroimaging study
Joubert, Sven; Vallet, Guillaume; Montembeault, Maxime; Boukadi, Mariem; Wilson, Maximiliano A.; Laforce, Robert Jr.; Rouleau, Isabelle; Brambati, Simona Maria (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 (HE) Three groups of participants ... -
Connected speech features from picture description in Alzheimer's disease: a systematic review
Slegers, Antoine; Filiou, Renée-Pier; Montembeault, Maxime; Brambati, Simona Maria (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 communication abilities of AD patients. ... -
Connected speech markers of amyloid burden in primary progressive aphasia
Slegers, Antoine; Chafouleas, Geneviève; Montembeault, Maxime; Bedetti, Christophe; Welch, Ariane E.; Rabinovici, Gil D.; Langlais, Philippe; Gorno-Tempini, Maria Luisa; Brambati, Simona Maria (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 a semi-automated analysis of ... -
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 ... -
La maladie d’Alzheimer comme syndrome de déconnexion et son impact sur le système du langage
Montembeault, Maxime (2019-03-13)La forme typique de la maladie d’Alzheimer (MA) se caractérise par des troubles progressifs de la mémoire épisodique. Néanmoins, les patients atteints par cette maladie présentent également des symptômes langagiers. Parmi les problèmes langagiers que ... -
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 ... -
The role of the left anterior temporal lobe for unpredictable and complex mappings in word reading
Joyal, Marilyne; Brambati, Simona Maria; Laforce, Robert Jr.; Montembeault, Maxime; Boukadi, Mariem; Rouleau, Isabelle; Macoir, Joël; Joubert, Sven; Fecteau, Shirley; Wilson, Maximiliano A. (Frontiers media, 2017-04)The anterior temporal lobes (ATLs) have been consistently associated with semantic processing which, in turn, has a key role in reading aloud single words. This study aimed to investigate (1) the reading abilities in patients with the semantic variant ...
