Reductions in lateral inferior and medial frontal gyri of the left hemisphere and postcentral gyrus of the right hemisphere correlated inversely with age in the BN but not the healthy participants, producing significant diagnosis-by-age interactions (P’s = 0.01 to 0.001). Reductions in inferior parietal lobule, bilaterally, correlated inversely with age in the healthy but not the BN participants, producing significant diagnosis-by-age interactions. Surface distances (in mm from the corresponding point on the surface of the template brain) are plotted on the Y axis. IPL, inferior parietal lobule; MFG, medial frontal gyrus; PoCg, postcentral gyrus; IFG, inferior frontal gyrus.
