The current analysis was designed to evaluate changes in the structural connections in the brain, as assessed by connectome mapping from diffusion tensor imaging (DTI) MR scans, among normal controls (NC), subjects with mild cognitive impairment (MCI), and subjects with AD in the Alzheimer's Disease Neuroimaging Intiative 2 (ADNI2). There were 101 ADNI2 subjects in the analysis. The bilateral insula weighted degree were significantly associated clinical diagnosis.
