Correlation analysis between relative regional brain atrophy and Fazekas scores, corrected for age, shows differential patterns in AD and PART. Pearson correlation analysis of relative brain atrophy residuals after linear regression with age per region versus Fazekas scores (periventricular and deep) among 2 groups of participants, distributed according to the absence (i.e. PART) or presence (i.e. AD) of neocortical neuritic plaques after neuropathological evaluation. The regions evaluated are anterior cingulate (AC), orbito-frontal (OF), fronto-insular (FI), medial temporal (MTA) and posterior (Post). Only showing pairs with p < 0.05 in the correlational analysis. Color indicates R Pearson coefficient
