How does Parkinson's progress over time?

Under this theory, Parkinson's only progresses to the substantia nigra and cortex over time.

Can stress cause Parkinson's?

Background: Animal studies suggest that Parkinson's disease (PD) pathology is negatively affected by stress. More stressful life events may increase the risk of PD. Stress increases damage to dopamine cells and results in more severe parkinsonian symptoms in animal studies.

In most cases, symptoms change slowly, with substantive progression taking place over the space of many months or years.

Theory of PD Progression: Braak’s Hypothesis

• The current theory (part of the so-called Braak's hypothesis) is that the earliest signs of Parkinson's are found in the enteric nervous system, the medulla and the olfactory bulb, which controls sense of smell. Under this theory, Parkinson's only progresses to the substantia nigra and cortex over time. This theory is increasingly borne out by evid...
