Yrs Ed, Years of Education; HC, Hippocampus; PHG, Parahippocampal Gyrus. Measures of brain volume are studentized residuals calculated relative to brain volumes obtained from a matched healthy comparison group (see Allen et al., 2006 for details). The cut-off for statistically reliable volume reduction was a studentized residual of −2.00 (p < 0.05).
