What a great advocate you are for your husband. so many years of misdiagnosis all the while no one would listen. I hope you are able to continue to have faith in a less than perfect system. Certainly his physicians had his best interests in mind while rendering care. given this condition so closely mimics Parkinson's, and drug therapy is so unpredictable in Parkinson's, it is difficult to determine that the condition is not "true parkinson's". The testing is not done unless the doctor has a suspicion it might be NPH. And I know caregivers are often perceived as overprotective worriers. My best to you and your husband. Again, good for you and your perseverance.
In the last analysis, we see only what we are ready to see, what we have been taught to see. We eliminate and ignore everything that is not a part of our prejudices.
