Prevalence, baseline studies and mortality rate in BD-MRI and related small-vessel diseases
| Prevalence at baseline | UPDRSMS | MMSE | Gait disturbance | Mortality rate at 30 months | |
|---|---|---|---|---|---|
| Normal MRIs | 112 (22.3%) | 1.87 ± 2.74 | 28.6 ± 1.17 | 5.1% | 4% |
| BD-MRI | 14 (2.8%) | 8.92 ± 0.3* | 26.6 ± 2.40** | 38.5%** | 33.3%* |
| ML-MRI | 23 (4.6%) | 4.36 ± 7.47 | 28.2 ± 1.50 | 13.6% | 22.2% |
| WML-MRI | 20 (4.0%) | 1.25 ± 2.07 | 28.1 ± 1.41 | 10.0% | 9.1% |
Statistically significant compared with normal MRIs and WML-MRI groups (*P < 0.05), and compared with normal MRIs, WML-MRI, and ML-MRI groups (**P < 0.05), respectively.
