antiparkinsonian agents

Summary

The goal of this research study is to help scientists better understand how mutations in the GBA (glucocerebrosidase beta acid) gene affects patients with Parkinson’s disease. Mutations in the GBA gene are the most common genetic risk factors for Parkinson's, affecting about 10 percent of the more than 6 million people estimated to have the disease. 
Through prior research studies we have found patterns of brain activity that are common among patients with Parkinson’s disease (PD). This study will continue to investigate these patterns in patients with PD with a GBA mutation and patients with PD without the GBA mutation. We hope that this information will one day improve treatment for the disease.
