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 ... -
Alzheimer’s disease and memory strength : gradual decline of memory traces as a function of their strength
Langlois, Roxane; Benoit, Sophie; Rouleau, Isabelle; Vallet, Guillaume; Joubert, Sven; Barbeau, Emmanuel J. (2016-03-29)Objective : Episodic memory impairment is at the core of amnestic mild cognitive impair- ment (aMCI) and Alzheimer ’ s disease (AD). The origin of memory deficits may result either from an encoding deficit or from an accelerated decline of the ... -

Differential involvement of the anterior temporal lobes in famous people semantics
Chedid, Georges; Wilson, Maximiliano A.; Provost, Jean-Sébastien; Joubert, Sven; Rouleau, Isabelle; Brambati, Simona Maria (Frontiers media, 2016-08-30)The ability to recognize a famous person occurs through semantic memory. Previous neuroimaging studies have shown that the anterior temporal lobes (ATLs) are involved in the recognition of famous people. However, it is still a matter of debate ... -
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 ... -
L’évaluation de la mémoire rétrograde dans la population québécoise âgée: Le PUB-40 et le PUB-12
Langlois, Roxane; Joubert, Sven; Benoit, Sophie; Dostie, Valérie; Rouleau, Isabelle (2015-09)L’évaluation de la mémoire représente une partie importante du travail des neuropsychologues cliniciens œuvrant en gériatrie. En effet, au Canada, environ le tiers des aînés rapporte une plainte mnésique dont les causes sont variées. Selon l’étiologie, ... -
An examination of semantic impairment in amnestic MCI and AD : What can we learn from verbal fluency?
Chasles, Marie-Joëlle; Tremblay, A.; Escudier, F.; Lajeunesse, A.; Benoit, S.; Langlois, R.; Joubert, Sven; Rouleau, Isabelle (Oxford University Press, 2019-04-17)Introduction The Verbal Fluency Test (VF) is commonly used in neuropsychology. Some studies have demonstrated a marked impairment of semantic VF compared to phonemic VF in Alzheimer’s disease (AD). Since amnestic Mild Cognitive Impairment (aMCI) is ... -
An examination of semantic performance in mild cognitive impairment progressors and nonprogressors
Delage, Émilie; Rouleau, Isabelle; Akzam-Ouellette, Marc-Antoine; Roy-Côté, Frédérique; Joubert, Sven; Consortium for Early Identification of Alzheimer's disease-Quebec (American psychological association, 2024-02-15)Background. Mild Cognitive Impairment (MCI) is a risk factor for developing Alzheimer’s disease (AD), and about half of older people with MCI will progress to AD within the next five years. The aim of the present study was to compare the semantic ... -
Functional network and structural connections involved in picture naming
Jarret, Julien; Ferré, Perrine; Chedid, Georges; Bedetti, Christophe; Boré, Arnaud; Joanette, Yves; Rouleau, Isabelle; Brambati, Simona Maria (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 to meaning” involves the middle ... -
The impact of time and repeated exposure on famous person knowledge in amnestic Mild cognitive impairment and Alzheimer’s disease
Benoit, Sophie; Rouleau, Isabelle; Langlois, Roxane; Dostie, Valérie; Kergoat, Marie-Jeanne; Joubert, Sven (2017)Objective: Famous people knowledge has been shown to be impaired early in Alzheimer’s disease (AD) and amnestic mild cognitive impairment (aMCI). However, the question of whether recently acquired knowledge is more impaired than remotely acquired ... -
Learning and vulnerability to phonological and semantic interference in normal aging : an experimental study
Chasles, Marie-Joëlle; Joubert, Sven; Cole, Jessica; Delage, Émilie; Rouleau, Isabelle (Taylor and Francis, 2022-12-07)This study compares semantic and phonological interference vulnerability across the full range of learning processes. Method: 43 controls aged 61–88 underwent a neuropsychological examination, French adaptation of the LASSI-L, and an experimental ... -
Memory for public events in mild cognitive impairment and Alzheimer’s disease : the importance of rehearsal
Langlois, Roxane; Joubert, Sven; Benoit, Sophie; Dostie, Valérie; Rouleau, Isabelle (2016-02-22)Ribot’s law refers to the better preservation of remote memories compared with recent ones that presumably characterizes retrograde amnesia. Even if Ribot-type temporal gradient has been extensively studied in retrograde amnesia, particularly in ... -
