Table 4.
Correlations between FA measures and cognitive performance are shown. All of these regions showed significant negative FA correlations for RClus3 (relative to RClus2 & 1), systolic blood pressure, or TC (Fig. 6). FX was correlated with most memory-related task measures (accuracy and RTs). In contrast, FX was not correlated with full scale IQ (FWAIS). Delayed recall on the REY Complex Figure Test (REY-D) was correlated with most of the regions identified. Working memory performance on the Spatial Distracter task (SD-C) was also correlated with most of the FA regions noted in this table. Overall, more FA regions were positively correlated with spatial task accuracy than verbal tasks.
