Mum with memory loss believes my deceased dad had affair

Hello,

First time posting on the dementia forum but I am so lost. My mum lives abroad and we lost my dad 5 months ago. The last 12 months of his life were a living hell. Mum accused him of having affairs and multiple prostitutes which were supposedly arranged by his physiotherapist through mum’s phone. At one point I had to call the police as she attacked him, he was already very frail. She would accuse him of crazy-making, as she said he would hide her things and then put them back to make her think she was going crazy. She has always been a difficult person (narcissistic traits).

Since his death, she has turned into a sweet almost child-like old lady. She’s been grieving and upset that he’s gone just like any normal person would. I’ve had no issue supporting her with multiple phone calls and going over the same conversations over and over. She refuses any sort of memory investigations or home help. I took her to the GP who said she clearly suffers from memory loss but they can’t force her. This means she has no outside support and I have no idea what type of dementia she has. She doesn’t hallucinate anymore since she was medicated for a psychotic episode about a year ago.

She occasionally talks about dad’s ’affair partner’. She says that he behaved very strangely towards the end and ‘you don’t know your real dad’ etc. these are things she’s said in the past as well when she’s been angry with him, he was the sweetest person I have ever known and extremely loyal to her when many wouldn’t have been. I have his mobile and reassured her there have been no phone calls to any unknown numbers on there (oh no but he used the landline!)

Today she appears to have reverted back to her old self and told me she’s glad he’s gone. That I don’t know who he really was, etc.

I don’t know how to cope with her if she reverts back to her old narcissistic self. I’m an only child. Help! How do you cope with hearing your parent speak so badly of your beloved dad?

I think I would assume that it's part of her own memory loss/dementia. She might be confused and it makes sense as an explanation to her.

This sounds s difficult to deal with @sandyrose.

Is she taking her medication? I suppose you have no way of finding out?

From what I’ve heard from a friend’s experience, the affair memory / ideation is sadly a common experience for dementia patients.
It doesn’t make it easier to deal with, but please know you aren’t alone - if you can possibly treat it as a symptom of the illness that may help you.

(Humour can also help if you find it; my friend’s DM was convinced that DF was living with his floozy under her bed, and they had the cheek to move with her when she moved to a hospital bed in a new care home!)

Oh bless you, OP. It's not her talking, it's the illness. As you have seen, it can disappear - the real her is there, but there's also a lady who, most of the time, will really be believing what she's saying.

I am also an only child and saw both of my parents through dementia. Dad stayed quite gentle, but Mum was more challenging. I don't think I did it very well but I survived by telling myself that this wasn't her. This was a confused lady, whose needs I did my best to meet. She was clean, well fed, safe . . . It was a real shock when, after four or five years of severe dementia she regained some consciousness in her final days, and we had a lovely conversation in which she thanked me for all I had done. I didn't even know that she knew who I was.

The Alzheimer's Society helpline was a lifesaver. It's staffed by people who understand and will listen and help when possible.

Sending best wishes to you.
