Table 1 Demographics, clinical characteristics and olfactory function in the GPI and HC groups.
| GPI (n=40) | HCs (n=37) | t/z/χ2 value | P value | |
|---|---|---|---|---|
| Age, years | 55.5±10.3 | 59.8±15.4 | −1.447 | 0.153 |
| Men, n (%) | 36 (90.0%) | 28 (75.7%) | 2.81 | 0.094 |
| Education, years | 8.9±3.2 | 10.2±3.6 | −1.746 | 0.085 |
| MMSE | 18.0 (11.0, 22.0) | 27.0 (25.0, 29.0) | −6.014 | |
| Total NPI | 26.0 (14.3, 45.0) | 0 (0, 1.5) | −7.124 | |
| OT | 5.9±2.0 | 7.7±2.4 | −3.544 | 0.001 |
| OD | 6.7±1.7 | 10.2±2.2 | −8.04 | |
| OI | 6.9±2.1 | 9.9±2.3 | −5.853 | |
| TDI | 19.6±4.2 | 27.8±5.3 | −7.544 | |
| Anosmia, n (%) | 10 (25.0%) | 0 | – | – |
| Hyposmia, n (%) | 19 (47.5%) | 9 (24%) | – | – |
| Normosmia, n (%) | 11 (27.5%) | 28 (75.6%) | – | – |
| MTA scores | 2.5±0.9 | – | – | – |
| Fazekas scores | 2.0±0.8 | – | – | – |
| Values for age, education, OT, OD, OI and TDI are expressed as mean±SD. GPI – general paresis of the insane; HCs – healthy controls; MMSE – Mini-Mental State Examination; NPI – neuropsychiatric inventory; OT – odor threshold; OD – odor discrimination; OI – odor identification; TDI – composite score as the sum of results for threshold, discrimination and identification; MTA – medial temporal lobe atrophy visual rating scale. | ||||
