De l’outil et du corps : Etude neuropsychologique des troubles praxiques et du schéma corporel dans les pathologies neurodégénératives

Abstract : Apraxia is a diagnostic criterion for neurodegenerativediseases and can reduce autonomy in these patients. Yet, the fewstudies that have been done in this domain rarely take into accountspecificities of dementia (e.g., evolution, diffuse lesions, differentphenotypes) and there is no theoretical consensus on apraxia. Tooluse disorders are mainly explained by the loss of stored knowledge(e.g., about tools or gestures) but recent models suggest to distinguishthe actual use of tools from common usage. Likewise, apraxiai sfrequently linked with the loss of body representations but a historicalperspective of the literature demonstrates that it is a relatively recentassumption. The present doctoral thesis submits an alternativeproposal by opposing body representation and more dynamic andneurological processes, that is, sensory integration. Thus, at thetheoretical level this work proposes a historical perspective and acritical review of existing literature, as well as an epistemologicalreflection that contrasts knowledge and reasoning, and that makes adistinction between specific gesture disorders and consequences ofother cognitive impairments on gesture production. At a clinical level,this neuropsychological research examines these different levels ofimpairments in patients through a differential approach. Results showthat the aforementioned theoretical considerations are clinicallyvalidated.
