(A) Voxel‐based comparisons of patients with young‐onset Alzheimer's disease (YOAD) with age‐matched controls. P < 0.05, correlated for multiple comparisons using family‐wise error. (B) Gray matter regions correlated with the ALPS‐index in the patients with YOAD with a statistic threshold of P _uncorrected < 0.001 and cluster size >100 voxels. (C) Regions showing overlapping in (A) and (B) in brown. Color bar represents T statistics. ALPS, diffusion tensor imaging along the perivascular space.
