Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: A<br> | Procedure: MRI<br>* This assessment will be planned in the year after the consent signAll patients will have one brain MRI performed in Henri Mondor Hospital on a 3T MR unit (Skyra, Siemens, Erlangen). The procedure will include: a 3D-FLAIR imaging a morphometric study based on a 3DT1 MPRAGE gradient echo sequence (TR / TI / TE = 2300/900 /2.9 ms) an analysis of the anatomic connectivity of the patient's brain assessed using a 1.5mm isotopic DTI with a high number of directions (HARDI / 65 directions / b=1500s/mm2). An evaluation of neuronal dysfunction using MR Spectroscopy. Spectroscopic data will be collected using a 2D CSI laser with a short TE technique. Magnetization transfer imaging providing information about integrity of membranes.<br>|
