Behavior significance of mean diffusivity (MD), radial diffusivity (DR), and axial diffusivity (DA) in the cingulum (hippocampus) (A ~ E) and fornix (F ~ H) tracts after adjusting for age, gender, and education. All diffusivity measures are positively correlated with GDS scores in the cingulum (hippocampus) and fornix tracts. MD and DR in the cingulum (hippocampus) but not in the fornix tract are negatively correlated with LMII-DR scores. Colored circles indicate individual participants belonging to CN (black), LLD (red), aMCI (blue), and aMCI-LLD (green) groups. MD: mean diffusivity, DR: radial diffusivity, DA: axial diffusivity, GDS: geriatric depression scale, LMII-DR: logical memory II - delayed recall.
