Hi,
In my experience, it has been both, as they progress whoever doesnt aggree with them or provide what they think they want in that moment gets the anger in that moment. They also tend to not remember they were even angry at that person. Hope this helps.

I don’t know how to answer that. Thankfully my mom is “good” with her caregiver. Perhaps it is somehow a way to express “independence” and “control” as your dad fights this disease. It’s a hard journey for all.
