Note. A, FDG precuneus as a function of amyloid burden. B, Hippocampal volume as a function of amyloid burden. C, Word list delayed recall as a function of FDG precuneus. D, Word list delayed recall as a function of hippocampal volume. Orange represents females and green represents males. Top row depicts PSEN1 mutation carriers, bottom row depicts non-carriers. Abbreviations: Amyloid Burden, mean cortical florbetapir standard uptake value ratios (SUVRs); FDG Precuneus, glucose metabolism in the precuneus relative to the whole brain; Hippocampal Volume, Hippocampal to total intracranial volume ratios.
