Hi My wife has OPC. For 7 years all the doctors we saw thought it was Parkinsons, finally we got a dr to put the correct name on it. All the meds for PD did nothing for her, she even had brain surgery out at Loma Linda and that did nothing. The Dr we are seeing is one of the tops in this area and he says they have nothing to help my wife, if you are having any luck with your patient I would like to know just what they are doing.. Thanks much.
