Demographic characteristics, clinical data, and tests scores on the apraxia subtest of the WAB in agPPA versus lvPPA subjects
| agPPA (n=21) |
lvPPA (n=26) |
P value | P value adjusted for age at onset, MMSE, and WAB-AQ score |
|
|---|---|---|---|---|
| Right handedness (%) | 25 (96) | 18 (86) | 0.31 | - |
| Female gender (%) | 13 (50) | 6 (29) | 0.23 | - |
| Illness duration, yrs | 3.2 ± 1.3 | 3.2 ± 1.3 | 0.82 | - |
| Age at onset, yrs | 67.2 ±6.4 | 61.7 ±9.4 | 0.02 | - |
| Education, yrs | 15 ± 3.2 | 15 ± 2.6 | 0.81 | - |
| MMSE (/30) | 26.7 ±3.7 | 22.0 ± 6.3 | 0.002 | - |
| WAB aphasia quotient | 82.3 ± 13.1 | 75.2 ± 16.8 | 0.11 | - |
| Upper limb apraxia | 13.8 ± 1.7 | 13.8 ± 1.7 | 0.99 | 0.21 |
| Facial apraxia | 12.4 ± 3.4 | 14.3 ± 1.1 | 0.02 | 0.03 |
| Instrumental apraxia | 12.4 ± 2.2 | 12.7 ± 3.1 | 0.77 | 0.0006 |
| Complex apraxia | 11.1 ± 3.3 | 11.3 ± 3.4 | 0.87 | 0.006 |
| Total apraxia | 49.7 ±7.4 | 52.1 ± 8.5 | 0.31 | 0.004 |
Data shown are mean values ± standard deviation. For each apraxia subtest, the range is from 0 to 15. Total apraxia score range is from 0 to 60. Lower scores indicate greater impairment.
