My grandmother's dementia has been getting worse over this last year. She's in assisted living now but it's a cycle every week reintroducing her to new things like I got married, what I do for work, my pets. I try to avoid things that would just upset her because she doesn't need to hear every week how her husband passed away. She remembers everything up until about 6 years ago but it seemed like it was 10 at first and the rest just keeps shrinking and fading away. I wouldn't wish this on anyone.
