This study focus on ambulant patients(with or without medication/ECT treatment), to find patients in an earlier stage. Cerebral perfusion with the MR sequence Arterial Spin Labelling, concentrations of different metabolites with MR spectroscopy and brain volumetry with BRAVO 3D T1 ax will be performed.
MR protocol: T2 sag, T2 FLAIR ax, ASL ax, MRS and 3D T1 ax. Scan time 45 min.
