My dad is diagnosed with either Parkinson's with dementia or multiple system atrophy (shy dragers). We are wondering if anyone stopped taking the Levo/Carbidopa or middodrene or pyridostigmine or Fludrocortisone or omneprozole? We have noticed a real down turn in my dads dementia. He can't even drive now and was doin much better just three months ago. Is this just regular progress of disease? My mom wonders if the meds are making him worse. She especially does not like the levodopa/carbo because it gives him a bad body odor. Any advise? Anyone got off meds? What happened? Thanks so much. Love to you all.
