I stayed with my sister suffering serious cognitive disfunction throughout her illness and ultimate death a few weeks ago. I saw in her all we’re seeing in Biden in the middle stages of her disease. You can communicate but as with Biden she wandered frequently.
Communicating is very touch and go as I’m sure Biden’s handlers are seeing. Following directions becomes a real issue....as we’re now seeing. Issues with how one walks.
My wife went through something similar with her uncle.
We had to remove the starter from his car because he would get in it and wander.
