Neuroimaging. Brain MRI (A-C) and FDG-PET (D). (A) Axial FLAIR, with no white matter hyperintensities; (B) axial SWAN, showing no microbleeds; (C) coronal FSE T2 PROPELLER, with no hippocampus atrophy or ischemic lesions; and (D) FDG-PET showed no regions of hypometabolism visually.

Scale for Semantic Interference and Learning, LASSI-L, showing a failure in recovering from proactive semantic interference). The other neuropsychological tests were unremarkable (Table 2). FDG-PET and MRI showed no abnormalities on visual analysis (Figure 1). Semi-quantitative analysis of meta-region of interest (meta-ROI) of FDG-PET was 1.19, indicative of hypometabolism in regions linked to AD.
