Extremely practical advice for how to deal with a family member who is in care for dementia, and how care staff and family can do well or badly with a number of given issues and situations and transitions. Almost all books about having family members with dementia are directed to caregivers, this is the only one I found that is not but is perfectly suited to my situation.
Generally the advice is to go along with whatever reality the person is living in - definitely do not try to talk sense into them! If they think they're 35 and have to go to work soon, let them think that and tell them you'll help them get ready; they'll forget in ten minutes anyway. If they don't know who you are, it's not because they've forgotten you exist but because in their reality you're probably a lot younger. One interesting point was that there will come a time when calling them 'mom' or 'dad' will make no sense to them and cause upset, so you may need to transition to calling them by their first name.

The only complaint I had was that she starts by going through all the different kinds of dementia, and basically says "if it's not vascular, or lewy body, or frontotemporal lobar, then it's Alzheimer's. The book by Tia Powell was more nuanced on this subject, probably because she is a doctor, talking about the complexities of defining Alzheimer's and stating that not all senile dementia is Alzheimer's... I don't think it really matters when deciding how to respond to any given situation, but I'm not sure that part was scientifically accurate.
