She is early 60s and seems healthy to all intents and purposes. However her mother has dementia and she cares for her.
Last weekend we had lunch and on two occasions she referred to my current partner 'Paul' as my previous partner 'Adam'. Adam cheated on me and the relationship ending was horrible so we never talked about him
Anyway twice she said 'So how is Adam?' or 'How was Adam's trip?'. About an hour apart. She apologised first time then said it again.
Then later she forgot her phone while we were out.
In the past she has suffered from anxiety which I know causes this kind of fog as well. But in a bit worried and I don't live very near her to see on a more ongoing basis.
