Thanks Laura for this information.

It is interesting but still just another measurement device to see how quickly/slowly we are deteriorating. In other pathologies, such as cancer or heart disease, such measurements have a purpose in that they prompt more or less aggressive treatment. With PWP, our treatments are usually added to or decreased as a result of our subjective response to questions from the neurologists. This study maps our progress into the depths of PD, and, while scholarly and thorough, does nothing to help us with our disease. It might be have been more productive to put the money necessary for this study into finding treatments that work.
