I wonder what the false-negative rate of this algorithm is. 99% (which I assume is the true-positive rate) is certainly impressive for such a simple test, though.

It would be all kinds of awesome if this turns into something that can be done reliably and routinely!

Edit: seems like 99% is only for later stages of Parkinson's, and the accuracy number is just off a 50-person sample. Less impressive, but still cool. http://www.forbes.com/sites/singularity/2012/07/03/new-softw...
