Correlation between hippocampal shape scores and visual memory (WMS-III Faces) performance within the PPA group. Shape scores that are more positive represent a hippocampal shape that deviates farther from the average control. (A–D) Correlation between hippocampal shape scores in the whole right hippocampus and its subfields and immediate visual memory (WMS-III faces: immediate scores) within the PPA group. (A) Whole hippocampal shape score vs. WMS-III faces immediate score (P < .01). (B) CA1 subfield shape score vs. WMS-III Faces Immediate score (P = .01). (C) Subiculum subfield shape score vs. WMS-III Faces Immediate score (P = .05). (D) CA2–4+DG subfield shape score vs. WMS-III Faces Immediate score (P = .20). Declines in immediate visual memory performance were correlated with an increased shape deformity in the right whole hippocampus, CA1, and subiculum. (E–H) Correlation between hippocampal shape scores in the whole left hippocampus and its subfields and immediate visual memory (WMS-III Faces: immediate scores). (E) Whole hippocampal shape score vs. WMS-III Faces Immediate score (P = .99). (F) CA1 subfield shape score vs. WMS-III Faces Immediate score (P = .08). (G) Subiculum subfield shape score vs. WMS-III Faces Immediate score (P = .11). (H) CA2–4+DG subfield shape score vs. WMS-III Faces Immediate score (P = .06). There were trends toward significance in the left CA1 and CA2–4+DG. (I–L) Correlation between hippocampal shape scores in the whole right hippocampus and its subfields and delayed visual memory (WMS-III Faces: Delay scores). (I) Whole hippocampal shape score vs. WMS-III Faces Delay score (P = .10). (J) CA1 subfield shape score vs. WMS-III Faces Delay score (P = .25). (K) Subiculum subfield shape score vs. WMS-III Faces Delay score (P = .12). (L) CA2–4+DG subfield shape score vs. WMS-III Faces Delay score (P = .09). There were trends toward significance in the right whole hippocampus and CA2–4+DG. (M–P) Correlation between hippocampal shape scores in the whole left hippocampus and its subfields and delayed visual memory (WMS-III Faces: delay scores). (M) Whole hippocampal shape score vs. WMS-III Faces Delay score (P = .77). (N) CA1 subfield shape score vs. WMS-III Faces Delay score (P = .03). (O) Subiculum subfield shape score vs. WMS-III Faces Delay score (P = .28). (P) CA2–4+DG subfield shape score vs. WMS-III Faces Delay score (P = .15). Declines in delayed visual memory performance were correlated with increased shape deformity in the left CA1.
