I've been on Sinamet for nearly four years, plus Amantadine, Pramipexole. I have virtually no symptoms of PD other than discovering to my great distress that I'm experiencing confusion when talking to people. If the conversation is more than a few sentences, I'll suddenly blank out and forget what we were talking about. This doesn't happen every conversation, but it is freaking me out. I'm assuming this is the beginning of dementia? I will of course discuss this with my neurologist but I hoping for some encouraging words from one of you. Could these episodes be a result of one of the meds I've been taking?
