    Normative data for the rey auditory verbal learning test in the older French-Quebec population
    (Swets Pub. Service, 2018-02-01) Lavoie, Monica; Gagnon, Jean-François; Joubert, Sven; Rouleau, Isabelle; Macoir, Joël; Hudon, Carol; Bherer, Louis; Blanchet, Sophie
    Objective: The aim of this study was to establish normative data for the Rey Auditory Verbal Learning Test, a test assessing verbal episodic memory, in the older French-Quebec population. Method: A total of 432 French-speaking participants aged between 55 and 93 years old, from the Province of Quebec (Canada), were included in the study. Using multiple regression analyses, normative data were developed for five variable of interest, namely scores on trial 1, sum of trials 1 to 5, interference list B, immediate recall of list A, and delayed recall of list A. Results: Results showed that age, education, and sex were associated with performance on all variables. Equations to calculate the expected score for a participant based on sex, age, and education level as well as the Z score were developed. Conclusion: This study provides clinicians with normative data that take into account the participants’ sociodemographic characteristics, thus giving a more accurate interpretation of the results.

    Analysis of naming errors in healthy aging, mild cognitive impairment, and Alzheimer’s disease
    (Association of Speech-Language Pathologists and Audiologists = Association canadienne des orthophonistes et audiologistes, 2019-04-01) Gallant, Mélanie; Monetta, Laura; Lavoie, Monica; Hudon, Carol
    The aim of this study was to document the functional origin of anomia in mild cognitive impairment in comparison to Alzheimer’s disease and healthy cognitive aging. An oral naming task of 260 pictures was administered to 20 individuals with mild cognitive impairment, 5 with mild Alzheimer’s disease, and 15 healthy controls. The mean total number of errors and types of naming errors were compared across the groups. The effect of psycholinguistic parameters and the efficacy of semantic and phonological cueing were also analyzed. Results showed a significant difference among the three groups’ total number of naming errors (Alzheimer’s disease > mild cognitive impairment > healthy controls). Similar types of naming errors were found among the groups and mainly consisted of coordinate semantic paraphasias. Further, less familiar words were associated with greater error probability in all groups. Finally, based on error types, psycholinguistic parameters, and efficacy of cueing, the main origin of anomia was determined for each participant and different patterns were observed among the three groups. In healthy controls, the origin of anomia was lexical. In mild cognitive impairment, the origin of anomia was lexical for 60% and semantic for 40% of participants. In Alzheimer’s disease, a degradation of fine and distinctive semantic features seems to be the main cause of anomia. Although the present data are limited due to small sample size, they will be useful in the development of appropriate interventions aiming to reduce anomia in the elderly.

    Rééducation fonctionnelle de l'anomie via tablette électronique : une approche novatrice en aphasie
    (2018) Lavoie, Monica; Macoir, Joël; Bier, Nathalie
    L’aphasie est un trouble acquis du langage pouvant survenir à la suite d’une lésion cérébrale, par exemple lors d’un accident vasculaire cérébral (AVC), ou en contexte de maladie neurodégénérative, comme c’est le cas dans l’aphasie primaire progressive (APP). Parmi les manifestations de l’aphasie, la plus fréquente est l’anomie, soit la difficulté à retrouver les mots précis au moment voulu. Bien que l’efficacité de l’intervention orthophonique soit clairement démontrée en aphasie post-AVC et en APP, les services à long terme sont actuellement limités, en raison de contraintes humaines et financières. Dans ce contexte, les technologies semblent une avenue prometteuse pour permettre aux personnes aphasiques de maximiser leur potentiel de rééducation, particulièrement si le vocabulaire travaillé est choisi en fonction des besoins du participant. Cependant, des études supplémentaires sont nécessaires afin de confirmer l’efficacité de cette nouvelle approche thérapeutique. OBJECTIFS: L’objectif général de cette thèse est d’évaluer l’efficacité des technologies pour la prise en charge de l’anomie acquise. Plus spécifiquement, l’étude 1 vise à réaliser une synthèse des écrits actuels sur l’efficacité de l’ordinateur et de la tablette électronique pour la rééducation de l’anomie post- AVC. Les études 2 et 3 visent à mesurer l’efficacité d’une thérapie autoadministrée via tablette électronique pour la rééducation de mots fonctionnels en aphasie post-AVC et en APP. MÉTHODE: Dans le cadre de l’étude 1, une recension systématique des écrits a été réalisée. Pour les études 2 et 3, une série de cas uniques a été menée auprès de quatre participants avec aphasie post-AVC et cinq participants avec APP. Les cibles du traitement ont été choisies avec chaque participant, en fonction de ses activités quotidiennes et de ses intérêts. Le traitement a été auto-administré via tablette électronique, à raison de quatre fois par semaine pendant quatre semaines. RÉSULTATS: La recension systématique des écrits réalisée dans le cadre de l’étude 1 a permis de démontrer l’efficacité de l’ordinateur et de la tablette électronique pour l’amélioration de la dénomination de mots en contexte d’anomie post-AVC. Dans les études 2 et 3, le traitement auto-administré via tablette électronique a permis une amélioration significative de la production des mots fonctionnels entrainés chez tous les participants. CONCLUSION: Les résultats issus de la présente thèse apportent un appui supplémentaire aux écrits actuels et confirment le potentiel des technologies pour le traitement de l’anomie en contexte d’aphasie.

    TDQ-30 : a new color picture-naming test for the diagnostic of mild anomia : validation and normative data in Quebec french adults and elderly
    (National Academy of Neuropsychologists (U.S.), 2019-12-03) Wilson, Maximiliano Agustin; Chagnon, Andréanne; Lavoie, Monica; Macoir, Joël; Hudon, Carol
    Objective: A reduction in lexical access is observed in normal aging and a few studies also showed that this ability is affected in individuals with subjective cognitive decline. Lexical access is also affected very early in mild cognitive impairment as well as in major neurocognitive disorders. The detection of word-finding difficulties in the earliest stages of pathological aging is particularly difficult because symptoms are often subtle or mild. Therefore, mild anomia is underdiagnosed, mainly due to the lack of sensitivity of naming tests. In this article, we present the TDQ-30, a new picture-naming test designed to detect mild word-finding deficits in adults and elderly people. Method: The article comprises three studies aiming at the development of the test (Study 1), the establishment of its validity and reliability (Study 2), and finally, the production of normative data for French-speaking adults and elderly people from Quebec (Study 3). Results: The results showed that the TDQ-30 has good convergent validity. Also, the TDQ-30 distinguished the performance of healthy controls from those of participants with mild cognitive impairment, Alzheimer's disease, and post-stroke aphasia. This suggests good discriminant validity. Finally, this study provides normative data computed from a study sample composed of 227 participants aged 50 years and over. Conclusions: The TDQ-30 has the potential to become a valuable picture-naming test for the diagnosis of mild anomia associated with pathological aging.

    Normative data for the dementia rating scale in the french-Quebec population
    (Taylor & Francis Group, 2013-08-14) Potvin, Olivier; Lavoie, Monica; Simard, Martine; Macoir, Joël; Callahan, Brandy; Hudon, Carol; Blanchet, Sophie
    The Dementia Rating Scale-2 is used to measure cognitive status of adults with cognitive impairment, especially of the degenerative type, by assessing five cognitive functions, namely attention, initiation/perseveration, construction, conceptualization, and memory. The present study aimed to establish normative data for this test in the elderly French-Quebec population. A total of 432 French-speaking elders from the province of Quebec (Canada), aged 50 to 85 years, were administered the Dementia Rating Scale-2. Age and education were found to be associated with the total score on the test, while gender was not. Percentile ranks were then calculated for age- and education-stratified groups. Previous studies have shown that cultural background can affect performance on the DRS and the development of culture-specific norms for French-speaking Quebecers could be very useful to clinicians and researchers working with this population.
