It is a non invasive procedure, which takes approximately three hours of your time. You go to the facility that is going to perform the scan and you are given something to drink and you have to wait about an hour. You go to the room where the scan will be performed, it takes about 45 minutes or so to do it. They can actually see in your brain if you are losing dopamine, which is a major clue of Parkinson’s. My results came back that yes I was losing dopamine and that I have Parkinson’s. There is no pain involved in this procedure.
