FIGURE 3. 18F-FDG PET MRglc data for age-, sex-, and education-matched control and FAD subjects. Regional MRglc is averaged across hemispheres. Compared with respective control subjects, all FAD subjects show reduced MRglc values. Two FAD subjects with MMSE scores of 27 of 30 (FAD-5) and 25 of 30 (FAD-6) are marked with a white circle and a white diamond, respectively, and 1 FAD subject with questionable impairment (FAD-3) is marked with a white triangle. Note that these subjects were not driving statistical effects. HIP = hippocampus.
