MIL was diagnosed with vascular dementia in May 2018. She was declining fairly slowly and managing well until lockdown. In the last 6 months especially she is getting noticeably worse.
We visited her at the weekend. We told her on Thurs we were coming up, rang on Saturday morning and she had no idea we were visiting when we got there. She seemed to recover a bit and we had a nice afternoon. Ten minutes after we left she called us on DH mobile and asked what we had done that afternoon (me, dh and dd, she couldn't remember us visiting).
Now every day she has phoned me asking what time we are arriving, convinced we are visiting that day and getting upset that we aren't. Its like she is stuck in a groundhog day loop.
Any advice on how to support her? She is getting increasingly confused but DH and his sister both have their head stuck very firmly in the sand.
