| Executive function | Trail making test part A (N = 122) | r = −0.20; p<0.01 |
| Executive function | Trail making test part B (N = 122) | r = −0.21; P < 0.01 |
| Executive function | Trail making test A–B (N = 122) | r = −0.18; P < 0.05 |
| Visuospatial and visuoconstructive abilities | Figure Rey copy (N = 143) | r = 0.24; P < 0.005 |
| Visuospatial memory | Figure Rey recall (N = 143) | N.S. |
| Language production | Verbal fluency for letter (N = 143) | r = 0.27; P < 0.001 |
