RESUMO
Diagnosis of primary progressive aphasia (PPA) is essentially based on the identification of progressive impairment of language abilities while other cognitive functions are preserved. The three variants of PPA are characterized by core and supportive clinical features related to the presence or absence of language impairment in different linguistic domains. In this article, we review the cognitive neuropsychological approach to the assessment of PPA and its contribution to the differential diagnosis of the three variants. The main advantage of this assessment approach is that it goes beyond the mere description and classification of clinical syndromes and identifies impaired and preserved cognitive and linguistic components and processes. The article is structured according to the main language domains: spoken production, language comprehension, and written language. Each section includes a brief description of the cognitive processes involved in the assessment tasks, followed by a discussion of typical characteristics for each PPA variant and common pitfalls in the interpretation of the results. In addition, the clinical benefit of the cognitive neuropsychological approach for the behavioral management of PPA is briefly sketched out in the conclusion.
RESUMO
The main objective of this study was to present the development, validation and normalization of the Quebec Semantic Questionnaire (QueSQ). The QueSQ is a 12-item questionnaire designed for the rapid screening of semantic disorders. Psycholinguistic parameters that can influence performance, such as the nature of semantic features and superordinate semantic categories, were taken into account during its development. Psychometric qualities of QueSQ were demonstrated during the validation process. QueSQ normative data were established on the basis of age and level of education, from a sample of 100 Franco-Quebecers aged 50 years and over.
L'objectif principal de cet article est de présenter le développement, la validation et la normalisation du Questionnaire Sémantique de Québec (QueSQ). Le QueSQ est un questionnaire comportant 12 items, permettant le dépistage rapide des troubles sémantiques. Il a été conçu en tenant compte des paramètres psycholinguistiques pouvant influencer la performance, soit la nature des traits sémantiques et la catégorie sémantique superordonnée. L'étude de validation a permis de mettre en évidence certaines des qualités psychométriques du QueSQ. Les données normatives du QueSQ, établies en fonction de l'âge et du niveau de scolarité, ont été obtenues auprès de 100 personnes franco-québécoises âgées de 50 ans et plus.
RESUMO
Aphasia is a chronic condition that usually requires long-term rehabilitation. However, even if many effective treatments can be offered to patients and families, speech therapy services for individuals with aphasia often remain limited because of logistical and financial considerations, especially more than 6 months after stroke. Therefore, the need to develop tools to maximize rehabilitation potential is unquestionable. The aim of this study was to test the efficacy of a self-administered treatment delivered with a smart tablet to improve written verb naming skills in CP, a 63-year-old woman with chronic aphasia. An ABA multiple baseline design was used to compare CP's performance in verb naming on three equivalent lists of stimuli trained with a hierarchy of cues, trained with no cues, and not trained. Results suggest that graphemic cueing therapy, done four times a week for 3 weeks, led to better written verb naming compared to baseline and to the untrained list. Moreover, generalization of the effects of treatment was observed in verb production, assessed with a noun-to-verb production task. Results of this study suggest that self-administered training with a smart tablet is effective in improving naming skills in chronic aphasia. Future studies are needed to confirm the effectiveness of new technologies in self-administered treatment of acquired language deficits.
