Neuropsychological and Brain Medical Imaging Study in Patients With Brain Damage

University Hospital, Rouen346 enrolled

Overview

Two groups of subjects will be constitute: (i) patients with circumscribed brain injury (including stroke, vascular malformations, tumor or circumscribed infectious lesions) or degenerative disorders and selective cognitive disorders; (ii) healthy control subjects. The objective of this project is to evaluate specific neuropsychological deficits and apply current brain imaging techniques (anatomical, diffusion, functional) to patients suffering from these cognitive deficits due to brain damage, in order to elucidate the brain mechanisms underlying these deficits.

Outcomes

Primary Outcomes

Cognitive deficit

The cognitive deficit of interest will depend on the localization of the brain lesion. The outcome measure could be a standardized neuropsychological test or an experimental test specifically elaborated for this protocol.

Time frame: 3 to 6 months
