The other project will use PET imaging to compare the blood brain barrier of people with Parkinson's disease to those who do not have the disease. It is hypothesized that biochemical changes that occur in the blood brain barrier of people with Parkinson's could allow greater accumulation of environmental toxins in the brain. If researchers are able to quantify these changes they may be able to identify people with the disease early and to track disease progression, as well as enable the targeted development of therapies that may restore normal blood brain barrier function.
