The score on the Conners Adult ADHD Rating Scales inattention subscale predicts cortical thickness in a left occipital area in men, covering parts of the middle occipital gyrus (1) and sulcus (2), but not in women. The uncorrected results of FreeSurfer’s surface-based analysis (p < 0.01) are shown in panel (A) for women and panels (B,C) for men. After cluster-wise correction for multiple comparisons, only the left occipital area in men remains significant [p < 0.01 (E,F)]. No significant associations between cortical thickness and inattention were found in women (D). In panel (G), individual mean cortical thickness in the left occipital area seen in panels (E,F) is shown as a function of the inattention score. Regression line and 95% confidence intervals (gray shade) are displayed [F(1,27) = 26.27, p < 0.001, adjusted R² = 0.4744].
