I dont' see a benefit to the patient....I got from reading this that it might better help a doc see when to recommend DBS....assuming the patient wants that, a big IF. Does it help tell a doc if/how well meds are working? That could be good, but a patient already knows that...this doesn't offer any new treatment options.

Comparing this to diabetes depresses me. Diabetes has been extremely well-funded for decades, and they have nothing more to show for a cure than the same-old insulin they've had forever...sure, there are newer and better delivery methods for that insulin, but nothing in terms of treatment...oh wait, I forgot, diet and exercise can reverse type 2 diabetes (I have family who did this)...but no one can sell that, not like a handy dandy glucose monitoring system, test strips, etc.

Call me cynical, but this seems like something an iphone app could do just as easily (and I don't have even had an iphone). It might be out there already, there are so many apps out there.
