Correlation between short term memory performance as indexed by the Rey verbal learning test and the amygdala volume and the entorhinal cortex thickness in the study groups. Pearson correlations were significant (p < 0.05) in the amnestic MCI group and in the entire sample, while non-significant in the control and in the non-amnestic MCI groups. Rey verbal test total score on the vertical axes equals the sum of words in the first five trials. red line, regression line in the aMCI group; dashed line, regression line in the entire sample; MCI, mild cognitive impairment; r and p, Pearson correlation coefficient adjusted for age and corresponding level of significance in the aMCI group.
