Liens entre le manque du mot et les troubles olfactifs dans la maladie d’Alzheimer

Abstract : Anomia and olfactory identification disorders are both early symptoms of Alzheimer's disease. In our study, we first looked for evidence of a global correlation between these language and olfactory disorders, and then depending on a specific category and subcategory, to understand better the brain organisation in semantic and olfactory processes. We presented lexical naming, categorical fluency, and olfactory identification tests to nine patients suffering from Alzheimer’s disease. The results proved a significant correlation between anomia and the olfactory identification disorder. More precisely, we observed a specific impairment of naming in the biological category, but not in the olfactory disorder. Finally, we found a correlation between these two disorders concerning the biological category, but not for the subcategory of fruits. Thus, the olfactory and language disorders, which already had brain correlates, revealed similarities in their functioning and processing characteristics, through their clinical correlations. We inferred that brain organisation was defined by its lexical concepts and networks, proving why the subcategory did not involve the same correlation. Our study highlighted the relation between olfactory and semantic memory and raises questions about the interest of olfactory priming in the speech therapy of anomia.
