I was surprised to see that Congressman Jackson included Parkinsons as perhaps a cause of Biden’s problem but smart man that he is said he wouldn’t diagnose Biden. I had someone tell me a few weeks ago that they thought it was Parkinsons and that surprised me. I always associated what little I know about it to having uncontrollable shaking. Maybe not.
If you have ever seen someone with Parkinsons... you have seen someone with Parkinsons.
What the means is it is different for everyone. Yes, many have the shake you spoke of, but it is different for everyone, and for many cognitive decline is an issue.
Could be, but as you said it is inappropriate for anyone to make a diagnosis without truly knowing.
There are a lot of things that can lead to Biden's current condition. He had a bleeding aneurysm at the base of his brain repaired in 1988, and then another aneurysm treated surgically later that year. That doesn't mean anyone post-aneurysm repair or intra-cerebral hemorrhage is going to develop gait or cognition abnormalities, but just like Muhammad Ali developed a Parkinson's like movement disorder after absorbing the blows he did in boxing, every brain injury carries the possibility of encephalomalacia, gliosis, and other changes that could affect some aspects of brain function.
I don't think he has classic Alzheimer's, but whatever it is he is no longer medically qualified to be in public office.
