The fact that she told you she had MCI indicates she's willing to talk openly about it. If you can (and I know it's hard for some people), be open with her. Ask her about her plans for the future, how she's feeling about it, etc. I know talking about things like that is hard, but it's even harder for the person who has the diagnosis but is in the early stages and people act as if it's something to be ashamed of or kept from everyone else. Too often it seems like people react to someone announcing a diagnosis of dementia as if they've just announced they caught a venereal disease.

I guess what I'm saying is remember it's not about you. It's about her. If you can, be there for her as she navigates the early stages. And I understand some people just can't do that, but if not, at least try to verify if she has others who are able to give her the support she needs. And remember, it could be any of us one day. I recently read that dementia strikes at least 20% of people over the age of sixty, so one out of five. We need to treat this as we would any other health condition, with openness and compassion.
