My stepmother went that way, and in late stage, she literally would repeat the same statement a dozen times. It is like she was a broken record. Her death was two years after that started occurring. I suspect that is why he will not do a cognitive test under any circumstance. He could not handle it. That is also why his handlers only let him answer previous scripted questions, and then only 2 or 3. He is very sick, I suspect. I doubt that he will make it to the midterms and the symptoms are about to become obvious to everyone, not just those with experience with the disease.
I felt sadness and sympathy for all of the poor dears I encountered working in those nursing homes. Some knew what was happening to them and it frightened them. They were the ones I got close to, to try my best to comfort them.
Some had no idea what was happening to them and they too
would also repeat the same stories over and over or one day recognize you and the next 10 minutes later they had no idea who you were and sometimes even become hostile towards you.
That's another aspect of dementia, the hostility and even aggressive behavior dementia patients are prone to and Biden is exhibiting that very behavior.
I hope he has a stoke, really. He's a vile man with no redeeming qualities. He deserves to live in pain.
