My mother is 90 years old and has been diagnosed with Parkinson's. He also gave her a prescription for the nausea,but it does not help. Her primary care doctor took her off the carbidopa and put her on Pramipexole, but I do not see that she's any better. She is totally dependent on me for everything and is scared to death of nursing homes. I get no help from my sister but have found a lady to come in for a few hours each week so I can get out to run errands, etc. I wonder if it's too late for medication to help her get stronger?
