New imaging test gives physicians better tool to diagnose Parkinson's disease
Date:8/25/2011

ready being used by the Michael J. Fox Foundation for its landmark biomarkers study, the Parkinson's Progression Markers Initiative (PPMI), to validate that the subjects have Parkinson's disease. Northwestern is one of the 14 U.S. medical centers enrolling for the PPMI, which is among the first clinical trials using DaTscan in this way.

"Currently, we are not able to say with certainty that those enrolled in Parkinson's studies have the disease," said Simuni. "With the addition of DaTscan, we can be much more confident in the status of research subjects in both the control and experimental groups. By having a better understanding of these populations, we should be able to have clearer outcomes and hopefully that will translate sooner into treatments and eventually a cure."

Researchers are also hopeful that DaTscan will prove to be useful in following the progression of Parkinson's throughout a patient's lifetime. "The disease is clinically measured at certain points of time to help physicians understand its development," said Simuni. "A lot of questions about how Parkinson's disease progresses can be answered if DaTscan is able to show us changes in the brain's chemistry over time."
