A MRI with postinflammatory white matter lesions in FLAIR-sequences. B Automated Veobrain MRI analyses of the same patient shows normal findings without atrophic changes C EEG finding with intermittent generalized slowing. D Perinuclear staining (which were identified in serum and cerebrospinal fluid of some OCD patients) on unfixed murine brain slices (Prof. Prüß, Charité Berlin).
