*Multivariate analysis of variance intergroup comparisons (IC):

Controls v MCI‐AT v MCI‐MCDT: a, MCI‐AT different from normal; b, MCI‐MCDT different from normal; c, MCI‐MCDT different from MCI‐AT; d, no statistical differences.

Controls v MCI‐MCDT with and without memory deficits: e, MCI‐MCDT with memory deficits different from MCI‐MCDT without memory deficits, MCI‐AT, and normal; f, MCI‐MCDT with and without memory deficits different from MCI‐AT and normal; g, MCI‐MCDT without memory deficits different from normal and MCI‐AT; h, MCI‐MCDT with memory deficits different from MCI‐MCDT without memory deficits.

MCI‐MCDT, multiple cognitive deficits type of mild cognitive impairment; MCI‐AT, amnestic type of mild cognitive impairment.
