All I know is that the lead investigator on the study said that they used buspar - that it was very effective but very short term. There was a suggestion that perhaps a "buspar ER" could be helpful long term. The other interesting news out of this study is that the patients they looked at who were transplanted 12-13 years ago or so, still had fully functioning dopamine neurons from the trransplant and did not have to take any Parkinsons meds at all. Their main issue was the dyskinesia. So it sounds like they're trying to reduce the rogue seretonin cells in the lab and then try the transplant technique again.
