She is 95 years old. The CNA was in the middle of changing her and walked out of room because she was called to help another CNA. She was left for 15 minutes waiting, not fully dressed, she can't do it herself. She told the CNA off when she came back. Then it triggers my mom that she thinks the CNA is talking about her. She gets paranoid and that's all she thinks about. It is difficult. Any suggestions. I went and told the head nurse and she told CNA next time she has to leave her make sure she is covered up.
Asking the staff to cover her up first was a good solution. I'm not sure I would call what happened "triggering", since elders with dementia lose their filters and sense of time, therefore acting like toddlers in which their every need is immediate and an emergency. There's no way understaffed facilities can pander to this.
Is your Mom on any meds for anxiety or agitation? If not, it may be time to have this discussion with her primary care doctor. Dementia robs people of their ability to regulate their own emotions so they very often need the aid of medications to keep them calmer. It's a mercy.
Unfortunately, when Alzheimer's hits we forget all we have learned, and we have to learn it all over again. Sad, that, but a fact. End of life care falls far short of perfection; I don't think that will change any time soon.
