My 89 year old father was diagnosed with Parkinsons about 6 months ago. He is taking carba levadopa, but appears to be getting worse. He has been seen by three neurologists and now is being followed by a "movement" specialist. She has been slowly increasing his dose, but it does not seem to help. A previous doctor increased more quickly and that was no good either. He is due back at the doctor next week. any help or suggestions would be greatly appreciaated.
