One of the things that they give dementia patients is something like Celexa, or Ativan to keep the restlessness down.
That is why someone visiting a dementia patient for the first time or not often, they will think they are “in a fog.” The fog is not the dementia. The fog is them being drugged to keep them from freaking out when they have a moment of clarity and realized how “crazy” they have become.
I know that is not a PC way of explaining it. But, it makes them move slowly and almost machine like. Their sense of balance is worsened by induced vertigo when they move quickly or stand up quickly. That is why you hold their hand or elbow. (Its not out of love or affection—its grounding the patient.)
The keys to me are the grimaced facial expressions, and the eye squinting; he also uses “catch phrases” that fill in for lost moments—eg, “the thing”, or “come on man.”
This guy is a mess. The longer they wait, the worse its going to be for them. They are trying to hold it together for the down ticket.
I imagine when he finally crashes and burns, the Bernie Bots are going to go ballistic. And the party is simply trying to keep it together.
I know what you mean about the catch phrases. My mom has trouble coming up with the right word, especially nouns. She says” that stuff” a lot.
I have had loved ones with dementia. I can verify.
