Correlation between neuropsychological test performance and volume of ROIs. A. Correlation coefficients between neuropsychologic test performance and volume of ROIs in the converter group. The converter group showed good inverse correlations between the score of the COWAT animal test and the regional volume of the left inferior lateral ventricle, and between the score of the COWAT Phonemic test and the right inferior lateral ventricle. B. Correlation coefficients between neuropsychologic test performance and volume of ROIs in the non-converter group. Interestingly, this group shows an inverse correlation between the score of the CDR-SOB and the right hippocampus, as well as between the score of the stroop color reading test and the left hippocampus. In addition, the CDR-SOB, S-GDS scores and the regional volumes of the parietal, frontal and temporal lobes were also inversely correlated. Spearman correlation test was performed. Correlation Coefficients by Spearman's rank correlation rho.
