Sometimes it's not important (like the last time she saw her friends for lunch) and sometimes it is (alcohol causes cancer so if she doesn't drink she doesn't need a mammogram, or she has a great memory and doesn't need to see a neuro). Sometimes she asks about past incidents where she hurt me and I don't want to lie to her about it, but if I tell her the truth she becomes very upset. Exaggeration and denial predate her memory loss and have always made it difficult to communicate with her. I managed this in the past by not speaking to her very often, which has been a great relief. However, now that she's getting older and experiencing memory loss, I am having trouble supporting her while still taking care of my own feelings.
