Age, education level, and neuropsychological test scores are expressed as mean ± SD.
MMSE: mini-mental state examination; ADL: activity of daily living; IADL: instrumental activity of daily living; Stroop T: stroop color-word test interference (time, sec); Stroop E: stroop color-word test interference (number of errors); FAB: frontal assessment battery; HDRS: the 17-item Hamilton depression rating scale. Statistically significant differences for P values are in bold.
