DM is 76yo, and her memory is failing. There's a strong family history of dementia. She's currently fine day to day with help from my (much younger, completely healthy) DF, but it's clear she has virtually no short term memory. For example, she can't remember that a drink on the table in front of her is for her and always checks. She also occasionally says things that are wildly untrue (e.g. that my godmother is living in a treehouse, that people from her church have come around to bully her).
The issue is that she utterly refuses to discuss her memory or go to the doctor, and becomes very distressed if this is raised. This is totally understandable given the family history and what she's seen of dementia in the elderly, but means we have no way of getting a diagnosis at this point.
So, my question is, is this a problem at this point? I'm aware it's not sustainable long term and her condition is likely to deteriorate, but is there any significant support or treatment that she'd be likely to get at this stage? Having tried several times to get her to seek help, my DF's view is that it's not worth making her upset at this stage when he can cope fine and as far as he can tell there won't be any real treatment options. I'm happy to go with what he wants as he's the one dealing with this day to day, but if there is a real advantage to getting a diagnosis now, I'd want to let him know so he can make an informed decision.
