Notes: Data are presented as mean (standard deviation); NC = normal cognition; aMCI = amnestic mild cognitive impairment; AD = Alzheimer’s disease; MMSE = Mini-mental state examination; HVLT = Hopkins verbal learning test; HAMD = Hamilton Depression scale;**p < 0.001 compared to NC; p < 0.001 compared to aMCI.
