The rate for the progression of parkinson's disease is different for each person. My Mom has had parkinson's disease for a little over 10 years now. I am pretty sure that she is in the final stages of the disease.She started out having the tremors in her right arm and hand. That was about it for a long time, up until the last couple of years. She started to really slow down. A few years ago, she started to walk with the assistance of a cane, and a couple of years ago, with the assistance of a 3 wheel walker. 6 months ago, she had fallen in her home. It was found that she had a tia stroke, which they call a mini stroke. And after that,she moved in with my husband and I. Quickly after that, she required 24 hour care. I now have to bathe her,brush her teeth, help feed her when she needs help,do mostly everything for her. She can no longer stand or get up by herself,and is in a wheel chair full time, and spends most of the day in bed. She has no appetite,either. She has gone down from 112 lb. to 95 lb. She also has had a problem with choking. 2 days ago, an ambulance took her to the hospital because she was choking on a piece of meat, and it had to be removed from her esophagus. She is now on a soft diet and is still choking, even on water. I called her doctor,and he is putting her on a thickening agent to be put in her water to make it easier to go down. She now also is experiencing morning dementia, which is new for her, and just started that about 2 months ago.She no longer can write or sign any thing. Her speech is impaired,too and has a difficult time with word retrieval.And another thing, she is always cold, no matter what the temperature is! I know that is common for parkinsons patients to experience. She has been put on appetite boosters, but they don't seem to help. And, she also takes a mild antidepressnt to help with her feelings of depression. She has a terrible time with her balance, and has fallen a few times trying to get up, or just sitting on the side of the bed. Good luck to you, and hope everything goes well for you and your Mom. I know it can be a difficult thing to deal with,for both of you.
