The impact of white matter lesion (WML) on FA maps is studied. We selected a group of AD patients without WML based on the Age-Related White Matter Changes (ARWMC) rating scale of the European Task Force, and another group of AD patients with severe WML for comparison. The AD subjects with severe WML show smaller differences compared to normal control (NC), while the AD subjects without WML show a more extensive difference compared to the NC. The results suggest that the AD group containing white matter lesions have more heterogeneity white matter abnormality, thus less likely to show significant differences.
