  1. +Simple correlation, the correlation between regional PI and corresponding cortical volume (ex. Frontal represented the association between frontal PI and frontal volume).
  2. #Multivariate linear regression analysis, corresponding cortical volume were dependents and regional PI were independents and adjusted for age and medial temporal cortex volume.
  3. Abbreviations: PI, perfusion index from SPECT images.
  4. *p < 0.01; numbers indicate correlation coefficient (p-value).
