Brief summary
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.
Interventions
BEHAVIORALNeuropsychological testing
Experimental test about cognitive deficit of interest and standard neuropsychological tests.

Inclusion criteria
* age between 18 and 80 years * french language * effective contraception for women during the study * informed consent * no alcohol intake the day before the exam * for patients only, focal cerebral lesion (stroke, malformation, tumor, inflammatory, infectious, traumatic), neonatal pathology or degenerative disease with cognitive deficit
Exclusion criteria
* for healthy volunteers: previous neurological history (except non complicated migraine), previous psychiatric history (except depression with good evolution or anxiety with maximum one anxiolytic treatment), or severe cranial traumatism * for patients: vigilance disorders, severe depression or anxiety. * for both: psychotropic medication other than a hypnotic or an anxiolytic at low doses without dose modification for at least one month, severe visual or auditory impairment, patient without judicial or administrative liberty, measure of legal protection or no capable to express their consent, pregnancy or breastfeeding, contraindication for MRI, participation in another trial or former involvement in another trial within one month
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cognitive deficit | 3 to 6 months | 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. |
