I told her she had Alzheimer's disease, which we've talked about several times. There was a far-away look in her eyes, like she was being reminded of something very troubling. I brought it up because I had started to read a book about Alzheimer's and I needed to know if she wanted me to tell her what I found out. She said she wasn't sure, but just talking about it was upsetting enough for me not to bring it up again.
