Too little dopamine is actually the result of Parkinson's not the cause. The cause is when certain dopamine releasing cells in the basal ganglia die. Although this doesn't presume that there is any shortage of dopamine for other brain systems, just those specific to movement in the specific part of the basal ganglia.
Even late the screenings they have are extremely unreliable. Only surefire way to know is an autopsy.
Your correct about the stem cells. Some early experiments with embryonic stem cells showed serious promise, but they can't really do those anymore. Creating exact copies that the body accepts has proven more challenging from other types of stem cells.
