FIGURE 2. Voxels with significantly lower GM density or glucose metabolism are shown in axial plane of standard brain. (A) Left caudate and putamen GM densities in DLB group were significantly lower than those of NC group (upper left row). Left hippocampal and parahippocampal GM densities in AD group were significantly lower than those of NC group (lower left row). Bilateral occipital, temporoparietal, and frontal glucose metabolisms in DLB group were significantly lower than those in NC group (upper right row), and parietal and posterior cingulated metabolisms were also decreased (not shown). Bilateral posterior cingulate glucose metabolism in AD group was significantly lower than that in NC group (lower right row) (P < 0.05, corrected). (B) Left caudate GM densities in DLB group were significantly lower than those of AD group (upper row). Bilateral occipital glucose metabolism was significantly decreased in DLB compared with that in AD (lower row), and glucose metabolism in bilateral frontal, parietotemporal association cortices and left posterior cingulate gyrus, was also significantly reduced in DLB (not shown) (P < 0.001, uncorrected).
