  1. Numbers represent means (standard deviation). Age and EDU; education, are measured in number of years. NC stands for normal elderly controls; MCI, Mild Cognitive Impairment; AD, Alzheiemer Disease; AUC, Area Under the Curve from ROC analyses on MCInp vs MCIp; GDS, Geriatric depression Scale; WRT, Word Reading Threshold is in milliseconds; MMSE, Mini-Mental Status Examination; LM2, Logical Memory delayed; VR2, Visual Reproduction delayed; RAVLT delayed, Rey-Auditory Verbal Learning Test delayed; TRAIL, Trail Making Test Subscale A; STROOPd, dots subscale of Stroop test; STROOPw, words subscale of Stroop Test; STROOPc, colors subscale of Stroop Test. a, indicates significant difference between NC and MCI; b, indicates significant difference between NC and AD, c, indicates significant difference between MCI and AD and * indicates significant AUC difference between MCInp and MCIp groups (p < 0.002).
