Rating quality measured by AUC, using SGA (attributes: WC, N, E, Density, Diameter, and ASP) correlated with clinical symptoms measured with MMSE and Lawton scales, in addition with Lawton, MMSE or both, classifying AD and MCI from NC, AD from MCI, and also classifying subtypes of MCI (aMCI or a+mdMCI) from NC or AD, or from each other.
