What do you say to your Mother, who has dementia, when one of her children passes away?

I would have reconfirmed it in the instance you describe here. When I reconfirmed it, I'd add, "Momma, we told you about it when it happened. You've just forgotten. It was months ago." I wouldn't bring it up. If she asked about her in a matter-of-fact way, I'd try just say she was busy and doing great.

That's me . . . And I would tweak my behavior as I needed to depending on mom's response...the objective being to cause her the least pain as possible.

I think the person should be told that a loved one has died, once. I read somewhere where telling them over and over may upset them and they greave all over again. Now I know some that just say OK when reminded. It all depends on the person your dealing with how they respond.

My mom asked about her brother who passed away years ago. And then would be upset when I told her he died; and become anxious. So when she talked about him, I'd just let her and when she asked if I'd seen him, I'd just say "no I haven't and I haven't heard from him"; lets go get an ice cream... and then she'd move on to another topic. I felt it was better to avoid the upset and not make her sad.

Depends on how bad the dementia is. If it is hurtful to you still, then by all means, don't tell her she died. You can always do so once you are up to it later and it doesn't matter anyway unless she is begging to see your sister and that makes her anxious.

Very difficult question, and a judgment call. My dad died last August 23rd and mom saw his body laid out and attended the memorial service, including arrangements. The reality of his death drifts in and out, and she will repeatedly ask for confirmation. For her, because finances are a key issue in his death, she has a strong need to know. I feel that she becomes more anxious and upset in that surreal world of hallucination and memory loss. She is still trying to hang on to reality no matter how painful.

I had to tell her many times over and over since Geri's death ... It's been a rough rough 2 years

I'm not sure my dad kept remembering that my mom had passed away; know he started calling me her and I just let it go, though at the end, as they often do, he seemed to know again in the sense of wanting to go to her

Firstly I'm sorry for your loss. I have no experience of this and am reluctant to advise you. I would only say something if she asks you directly and then just be very matter of fact if you can manage it, then change the subject. If you think you're going to get upset, then just say she's gone on a long trip and you don't know when she'll be back.

Thanks to all for your answers/comments to my question. I guess there really is no definitive answer - at least an easy one. But it is comforting to know that I am not alone in this journey and that every day hundreds of us are facing these types of issues with our aging parents. Hugs to all.

You could say it in a calmer way, such as "Mary" went away for a while." Hopefully, since she has dementia, she won't remember to ask when "Mary" is returning.

My Mom is always asking where my father is, when is he coming to get her, etc. After telling her he died 5 years ago and upsetting her every time, I have taken up to telling her he's gone on a big fishing trip over to his favorite coastal town and that he will be back in a few days. Seems to work. Plus she doesn't cry. She won't remember the answer for 3 minutes anyway, why upset her? Come up with a likely story for why the relative is MIA and tell her that. By telling the truth, you are intentionally hurting her, for no gain because she won't remember what you said; it just makes her sad in the moment.
