  1. The value are expressed as mean (standard error) adjusted by age and education. SD standard deviation. *calculated by ANCOVA adjusted for age and education, same letters such as a and b in same row indicate differences at the 5 % significance level by post hoc test of Bonferroni F. §parameters of Finger Tapping Speed are the number of taps for 10 s
