Stages in the development of Parkinson disease-related pathology

Stages in the development of Parkinson disease-related pathology
Parkinson disease presymptomatic and symptomatic phases.
(Panel A) The presymptomatic phase is marked by the appearance of Lewy neurites/bodies in the brains of asymptomatic persons. In the symptomatic phase, the individual neuropathologic threshold is exceeded (black arrow). The increasing slope and intensity of the colored areas below the diagonal indicate the growing severity of the pathology in vulnerable brain regions (panel B). The severity of the pathology is indicated by darker degrees of shading in the colored arrow left.
(Panel B) Diagram showing the ascending pathologic process (white arrows). The shading intensity of the colored areas corresponds to that in panel A.
PD: Parkinson disease.
