Has anyone ever heard of someone having a seizure in later stages of Parkinson's or as a result of switching to Sinemet CR? My mother switched to Sinemet CR about a month ago, and had an "epileptic" (pardon the spelling) type seizure at the end of last week. I'm always concerned that the GP does not know enough about Parkinson's, so I called the Parkinson's clinic my mother goes to to get a "second opion" of how they handled things, and what they should be doing next. There never seems to be enough communication between the 2 doctors. The nurse at the Parkinson's clinic said it may not actually have been a seizure and suggested that if the doctor at the Senior's/Chronic care home where my mother stays have not already done it, that they should order an EEG to determine if it truly was a seizure. I passed this info. along to the nurse and she was to suggest this to the GP. I also suggested he talk to her Parkinson's specialist and provided them with the number. They have already scheduled a CT scan. The GP at the home put her on Dilantin (not sure of the spelling) to prevent further seizures, and because of this, they have also reduced her Sinemet. The doctor at the home said there was a very small chance that if she had another seizure it could kill her. The nurse at the Parkinson's clinic thought that this was a bizarre statement - i.e. that this was not likely to happen.. There's not much else I can do except keep pushing the GP to consult with the specialist. It's hard when the specialist and I are in one city and my mother is in another. If anyone else has heard of a similar situation, I would appreciate your comments.
