misdiagnosis?

[flyfisher800]

My  wife, who is 83 was diagnosed with PD 3 years ago. She has tremors in both hands, the right foot, and the mouth. She also has problems swallowing and gets what she calls the jitters, internally. She has no problem with speech, mobility, however, she is slow in her movements, but not shuffling. great strenght in her arms and legs.
At the time of diagnosis, she had been taking Raglan for nausia. I asked if she could be having side effects from this medication. The neurologist said no. She has been taking it for 15 years.. Just in the last few days, she has stopped taking the Raglan, except in the morning. She had been taking it 3 times aday at meals.   It has got me thinking about the side effects of Raglan again, and I still have a concern that she is having side effects from it and not PD.
Am I wrong? Does the MRI she had show that she has PD? If an MRI in not conclusive, then can it be possible that she has been misdiagnosed? Is it possible that she may not have PD? Sorry for all of the questions at once, but they are all tied together.
I have already discussed this with the Dr and am not satisfied with the answer, so there is no reason to ask again..
Thank you for your help.

Thank you for your response. We are presently discontinuing the reglan. I don't know if that will reduce the tremors if they have been a product of the reglan and not of PD. If they are from the reglan, then we are treating the wrong problem. the leavadopa or whateer it is, doesn't seem to reduce any of the tremors and they are getting worse. You can see my frustration in trying to help her. I think we will start again with the diagnosis with another dr for a second opinion after I find out if the MRI was conclusive..If so.. we deal with PD. If not we get a second opinion.. Does that sound like a good plan?
thank you

Parkinsons disease effects different nucleus in the brain. So there might not be a complete typical Parkinson's disease in everyone. There might be tremors, some associated with memory and some complete with classical cog wheel rigidity, gait and speech disorders.
So the diagnosis of Physician is not of a much concern as Neurologist come to conclusion based on investigations. MRI is conclusive most of the times.

Reglan increases the contractions of the stomach and small intestine, helping the passage of food. It is given to treat the symptoms of diabetic gastroparesis, a condition in which the stomach does not contract. These symptoms include vomiting, nausea, heartburn, feeling of indigestion, persistent fullness after meals, and appetite loss.
Side effects may include:
Drowsiness, fatigue, restlessness
In addition, Reglan may cause symptoms similar to those of Parkinson's disease, such as slow movements, rigidity, tremor, or a mask-like facial appearance.

But if you are worried then you always can go for a second opinion.
Take care!
