Mama is 87 and doesn't remember much from years ago and is worse with things that happened recently, even yesterday. And even though she may not remember peoples' names, she does remember them. I have no more fear of her ever forgetting who I am now that she has lived with me for all the years of her aging. She remembers to take care of her cats, dog, birds and turtle though it gets harder for her to get around every day. She is a very routine person so her days do not vary much at all. Everything done at a specific time of day. I never had children to raise and never needed to be so scheduled or routine. My days happen as they happen. Now of course, mostly in caring for her and my disabled hubby. Just wanted to know if anyone has had the experience of one of their parents forgetting them or other family members. I would still care for my mom if she didn't know me but I don't think it will happen. Especially after reading all the experiences of caregivers on this forum and not hearing that happening in their cases.
There really is no point in being afraid of this. What will be, will be. It will be time enough to be bummed about it IF it happens.
My husband knew everybody in his life right up to the end. That is typical with Lewy Body Dementia.
My aunt, 100, with dementia, still recognizes me, even though I seldom see her.
My mother, 95, with dementia, recognizes all the family members who come often to visit. She recognizes the less frequent visitors when they tell her who they are. This week a grandson visited whom she hasn't seen for a long time. She did not recognize him at all, but he reminded her about how they always played cards and some other things and she ended up enjoying his visit. She was pleased that such a nice man had been a part of her life, and that he remembered her even if she didn't remember him.
As far as I know, there is nothing you can do to stop this trait from developing if it a part of a person's dementia. From what you write, I'd be surprised if you mother every forgets who you are. But it is not impossible.
