Depression is a symptom of Parkinson’s disease, separate from the emotional response that comes with a diagnosis. As many as 50 percent of people with Parkinson’s show clinically significant symptoms of depression at some point in their disease course.
Depression in Parkinson’s may be due to the underlying changes in brain chemistry and circuitry from the disease itself. Evidence for this includes the fact that depression can predate a Parkinson’s diagnosis by a decade or more. More information is available on our Depression and Anxiety page.
The Michael J. Fox Foundation continues to pursue a single, urgent goal: the eradication of Parkinson’s disease. Explore our website for more information, connections to the Parkinson’s community, and resources for living with Parkinson’s disease.
