| Short survival (<5 years) | Associated with AD-type pathology, early cognitive decline, rapid progression of motor features |
| Median survival (6-8 years) | Typical of pathologically confirmed corticobasal degeneration (CBD) |
| Long survival (>10 years) | Associated with genetic forms (especially GRN mutations), slower initial progression |
| Respiratory complications | Aspiration pneumonia is the most common cause of death (40-60%) |
| Infection | Other infections (urinary, respiratory) |
| Neurological complications | Fall-related injuries, seizures |
| Other | Cardiovascular disease, malignancy (similar to age-matched population) |
