MMSE: mini mental state examination; TMT-A/B: trail making test—part A/B; FWT: five-word test; IRS: immediate recall score; DRS: delayed recall score; FRS: free recall score; TRS: total recall score. ^aThe table shows the scores adjusted for gender, age, and education level. Statistically different parameters: controls versus MCI, °controls versus AD, and ^§MCI versus AD.
