Correlation analysis between brain structure changes and cognitive score changes in patients (A) and controls (B). A significant association was found between the left superior parietal lobule (SPL) cortical thickness change and WAIS digital span (backward) change in patients (r = 0.57, p = 3.4 × 10−4) but not in controls (r = 0.09, p = 0.54)
