Interesting! That's exactly one topic where I did some research during my internship abroad. The thing about Parkinson and Substantia Nigra is, that when the first symptoms appear, the most part of the Dopamine has gone and medical treatment can only help a bit to delay the disease. Perhaps in a few years we visit the doctor regularly for brain-check-ups, because with ultrasound and improved medical imaging* you can detect the loss of Dopamine and are able to react very early...
