  2. Abbreviations: N number of participants, SD standard deviation, RAVLT Rey Auditory Verbal Learning Test, LM logical memory, MINT Multilingual Naming Test, CN cognitively normal, MCI Mild Cognitive Impairment, AD Alzheimer’s disease
  3. *Since MINT was added to the ADNI neuropsychology battery only recently, MINT scores were missing for 26 of our study participants
  4. In the Trail Making Test, a higher score denotes worse performance
