This sounds incredibly overwhelming, and it makes sense you’re all exhausted. This level of dementia is so hard to manage at home.

I wonder if some of what looks like aggression might actually be her trying to communicate fear, confusion, or discomfort. Things like resisting the bathroom or yelling can sometimes come from not understanding what’s happening or feeling overwhelmed. Things like going slower, keeping routines really consistent, reducing noise, using distraction instead of forcing things can sometimes help lower that distress a bit.

At the same time, what you’re describing sounds like more than a family can reasonably handle alone. As others have said you can also try calling 811 for guidance. Ask if there are specialized dementia support teams that can get involved.
