After months of testing with 2 neurologists, dx. finally made, I do have Parkinson's Disease, and probably what they call Parkinson's Plus. There are at least 5 variants of the Plus, won't know for sure which until about 3 months from now. All of them lead to rapid progression, and can hasten dementia. Still stunned with this dx. For you other Viet Nam Vets, Parkinson's is already on the Agent Orange disease list.
Sorry to hear of your continued adversity in the health department dude. My uncle, also a VV and career army helicopter pilot, has very bad tremors due to exposure to AO during the war. His docs have gone back and forth on whether he has PD or not, but it's clearly gotten worse over the years. No problems with dementia or speech yet thankfully.
Here's to hoping you find some joy during the holiday season brother.
