I agree with DanL, it isn't worth it to argue with your husband. It appears that he is losing more of his short term memory and that may be why he is resorting to previous stores, etc. In the scheme of things, does it really matter what he calls it. You knew what he meant and so he is still communicating with you. Same with country names etc. He is most liking frustrated that he can't quite get it right. Pointing out to him when he is wrong doesn't help. In the beginning, I tried to correct my husband. Eventually I started biting my tongue so that I wouldn't try to correct him all the time. Now it is easier. I don't get upset and neither does he. I think because my husband would have good days and bad, I was in denial that he couldn't understand or didn't call things by the right name. Now I realize that it is a downward spiral and I appreciate his good days as a blessing. He is not going to "get over" dementia. It is what it is.
