| Summary, etc. | RésuméNous présentons ici trois travaux de neuropsychologie réalisés sur l’évaluation et l’étude de la dégradation de la mémoire sémantique dans la maladie d’Alzheimer, dans la démence sémantique et dans la variante frontale de la démence fronto-temporale (vf-DFT). Tout d’abord, nous avons recherché les processus cognitifs et les substrats neuronaux impliqués dans les performances aux épreuves de fluence verbale de patients souffrant de démence sémantique et de vf-DFT. Nos résultats confirment l’aspect multi-déterminé des épreuves de fluences et le fait que les déficits sémantiques observés chez des patients vf-DFT sont le reflet de troubles exécutifs et de la mémoire de travail. Ensuite, afin d’étudier la dégradation de la mémoire sémantique et de son organisation, un paradigme d’amorçage sémantique manipulant différents types de liens sémantiques nous a permis de montrer que, dans la maladie d’Alzheimer et la démence sémantique, la dégradation des connaissances sémantiques génériques affecte en premier lieu les attributs distinctifs des concepts. Enfin, dans le cadre de l’évaluation de troubles sémantiques précoces, nous présentons une batterie d’épreuves originales permettant d’évaluer la familiarité de visages et de noms, les connaissances sémantiques biographiques et la dénomination de visages de personnes célèbres. |

| Summary, etc. | The semantic memory: organization and assessmentHere we report three neuropsychological works dedicated to the examination and degradation of semantic memory in Alzheimer’s disease, semantic dementia and the frontal variant of fronto-temporal dementia (fv-FTD).The first work was designed to study the cognitive processes and the neural substrates involved in the performances on verbal fluency tasks in patients suffering from semantic dementia and fv-FTD. The performance of fv-FTD patients in both fluency tasks mainly depend of their executive abilities while those of SD patients in both tasks were restricted by the impairment of their semantic memory store. Our results emphasized the multi-component nature of verbal fluency tasks of which cognitive specificities and neural substrates need to be well understood for an efficient use. We also report a study of the semantic memory deficits in Alzheimer’s disease and semantic dementia. In this work we used an original paradigm based on semantic priming effects for different kinds of semantic links. The results showed that in Alzheimer’s disease and in semantic dementia, the perturbation of generic semantic knowledge firstly concerns the specific features of concepts. This impairment pattern totally fits with the connexionnist models of semantic memory. Finally, to contribute to the detection of early semantic deficits we propose a battery of tests assessing familiarity of faces and names, semantic biographical knowledge and face naming of 16 famous people. For each people, matching tasks evaluate two types of biographical knowledge, a shared feature (the profession) and a more specific feature. In order to distinguish a central loss of knowledge from access difficulties, semantic matching tests use the same material proposed in two different forms: faces and names. |
