Values are presented as means (±SD). CO, control; MCI, mild cognitive impairment; AD, Alzheimer’s disease; CERAD, The Consortium to Establish a Registry for Alzheimer’s disease; MMSE, Mini-Mental State Examination; SD, standard deviation. Bolded p-values indicate significant differences between groups.
