Parkinson's Progression Markers Initiative (PPMI)
The Parkinson's Progression Markers Initiative (PPMI) is a large, ongoing research study aiming to identify biological markers—such as imaging findings, blood, and spinal fluid changes—that can signal the onset and progression of Parkinson’s disease. By studying people with Parkinson's, those at high risk, and healthy individuals, PPMI seeks to improve early diagnosis and develop better treatments. The initiative involves researchers worldwide collaborating to understand the disease better and find ways to track its progression objectively.
