TUG-DT: Timed Up and Go test with dual task; MoCA: Montreal Cognitive Assessment; MMSE: Mini Mental State Examination; E/(H+E) number of word errors per total words; H/time: hits per unit of time; Words/time: number of words per unit of time; NS: non-significance;

p<0.05;
**
p<0.01. Orientation and abstraction domains and the number of steps according to the TUG-DT are not included in the table because the correlations were not significant.
