Significant simple effects (p < 0.05) of the age groups (I, II, III) and disease (CON, HTN) factor is itemized and marked as “+.” FA, fractional anisotropy; MD, mean diffusivity; RD, radial diffusivity; AD, axial diffusivity. Age group I – 25–47 years old, II – 48–56 years old, III 57–71 years old. CC, corpus callosum; L3, cingulum (hippocampus) L; L5, inferior fronto-occipital fasciculus L; L6, inferior longitudinal fasciculus L; L9, uncinate fasciculus.
