Kevin was on apokyn for some time until he had his DBS. While the DBS allowed him to reduce his meds dramatically (thereby ending his dyskenisia) it was does not stop the progression of the PD. In the end, he was unable to swallow without aspirating and he choose not to have a feeding tube. I think he was tired of fighting the disease and living with it's ravages. He died of Parkinson's and we made certain that was clearly stated on the death certificate. Many times, people allow the secondary cause to be listed, and we have always felt that skews the statistics.
