Samantha - I understood that the only definitive test for Parkinson's was to slice open the brain during autopsy. (I don't know any Parkinsonians who have volunteered for that test so far). Has anyone else heard of Atlanta being the only place doing definitive diagnosis? Can you give us more information about what their testing consists of? There are a number of Parkinson's specialists across the country who are routinely diagnosing Parkinson's using physical findings alone, or in combination in some cases with a smell test. The rule of thumb is that, if the Parkinson's meds help, it's Parkinson's, and if they don't, it's not. Has your husband's condition improved since he started on the medications? I'm not a doctor, so I don't want to appear to be practicing medicine without a license, but that does sound like a lot of medication for someone diagnosed only two years ago. Could you ask your doctor about gradually cutting down on some of the doses to see whether his symptoms improve or worsen? If a trip to Atlanta is possible for you, it might be well worthwhile just to have another opinion. I think it's unusual for a relatively young Parkinsonian to have hallucinations only a couple of years post-diagnosis, and it seems likely that something in the drug combinations could be responsible. If you could tell us a little more about his symptoms prior to diagnosis versus his symptoms after starting the medications, we might be able to be a little more helpful. But I think most of us would advise getting a second opinion. It would ease your mind about the diagnosis, and as I mentioned, might result in improved treatment. Good luck to both of you.
