Dysconnexions et récupération des processus langagiers post-AVC

Abstract : Stroke prevention and care constitute important public health issues. Studying the prognostics of aphasia post-stroke is therefore critical. Finding prognostic markers would enable to : adapt the objectives, the therapeutic treatments and assistance for the patient, as well as bring new information for research progress. This work will study the recovery of aphasic disorders in relation with dysconnexions of white matter for each language process. This study will analyze a group of 35 patients presenting aphasic disorders after stroke. We observed lesional properties and dysconnexions visible on structural MRI images, taken during the critical period after stroke, by associating them with the evolution of the language disorders evaluated with the BESTA, at critical phase and 1 year after stroke. We have not demonstrated that white matter dysconnexions, taken in isolation, are factors of aphasic disorders recovery. However, we have evidenced links between some white matter connexions and language processes consistent with functional connectivity models for language. Considering preserved cerebral areas linked to damaged areas would be a valuable complement to this research.
