  1. All data were compared via the Kruskal–Wallis test followed by the Bonferroni correction
  2. ADD Alzheimer’s disease dementia, MCI mild cognitive impairment, NDC non-demented control, IQR interquartile range, DT detection threshold, RT recognition threshold
  3. a Significant difference between NDC and both MCI (p < 0.05) and ADD (p < 0.05)
  4. b No significant difference by multiple comparisons
  5. c Significant difference between NDC and ADD (p < 0.05)
