@rubyredkate Thank you for your comment. I'd like to highlight something you said about not making a comment when your husband experiences déjà vu. For a person with dementia or MCI it's better for communication and for the relationship if you go along with what the person said even if you know it is incorrect. This can actually be a conversation starter such as "tell me about this place", or "is there more about that TV show you'd like to share?" or something like that. I don't think there is a safety issue here so why not go along?
