Figure 1. Frequency of neuropathologic disorders with antemortem clinical diagnosis of PD.

Figure 1

The pie chart shows the frequency of pathologic disorders that present with Parkinsonism without dementia in the Mayo Clinic brain bank (n=132). The most common pathology is that of LBD (brainstem predominant (BLBD), transitional (TLBD) or diffuse (DLBD)). The next most frequent disorder is progressive supranuclear palsy (PSP), followed by multiple system atrophy (MSA) and vascular Parkinsonism (VaP). Corticobasal degeneration rarely presents as PD. Other rare causes of PD include nonspecific substantia nigra degeneration associated with basal ganglia pathology or with frontotemporal degeneration (with or without motor neurons disease).
