Read our Parkinson Disease research guide →Researchers are using a specialized brain imaging technique to study how nerve cells in the brain are affected in people with Parkinson's disease caused by a LRRK2 genetic mutation. This study compares people with this genetic form of Parkinson's to people with Parkinson's disease without the genetic mutation. The goal is to understand why people with the LRRK2 mutation sometimes experience different symptoms and progression patterns.
Parkinson's disease affects multiple systems in the brain, not just the dopamine system that doctors have traditionally focused on. Recent research suggests that the cholinergic system — another important brain signaling network — may play a protective role in some people with Parkinson's. Understanding how this system works differently in people with the LRRK2 mutation could help doctors better predict who will develop certain symptoms and eventually lead to better treatments.

If you qualify, you would visit the University of Michigan for brain imaging scans using a specialized PET imaging technique that allows researchers to visualize nerve cell structures. You would also likely have an MRI scan to rule out other brain conditions. The study involves a small group of 15 participants, and researchers will compare your brain imaging results to those of people with Parkinson's disease who do not have the LRRK2 mutation.
