a The distribution of the Mini-Cog test scores, which was administered only to the HC population. The range of the scores is 0–5, with 5 indicating no cognitive decline. HC inclusion required a score > =3. b The distribution of the MMSE scores in the MCI population. The range of the scores is 0–30, with scores < =25 suggesting cognitive impairment (dashed line). There was no threshold for inclusion. c The ADCS-ADL-MCI survey scores were significantly different between the HC (blue) and MCI (red) populations with higher scores indicating better daily functioning. Mean ± 1 SEM (standard error) for MCI and HC across behavioral measures of task performance within each condition of N-Back (d) and Verbal Fluency (e). Independent t-tests were conducted. Uncorrected significant differences are indicated by symbols above the bars: †p ≤ 0.1, *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001, ****p ≤ 0.0001.
