My mother, who has Alzheimer's Disease, has recently begun having episodes where she believes that our father who passed away 17 years ago, is late coming home from work and she has not heard from him. She is very concerned about him and wants us to try to find him. She also has had times when she asks us to help her find her children who have gone out to play and haven't come home yet and it is getting dark. With both of these types of episodes, she responds that "she knows" when we explain to her that our father passed away and her children are grown. Within 30 minutes, she has no memory of these episodes at all. Is this something that is to be expected with Alzheimer's? We took her to her doctor to make sure there was no other reason for this and none was found. Up until now, she has been able to continue living in her home with visits and help from us. Should we be considering home health care or other options since this has begun to happen? It is so hard to know what to do. Thank you for any advice you can provide.
Sometimes a person with Alzheimer's will relive an earlier event if they experience a "trigger" that is similar to what happened when the previous event occurred.
Since your Mother has no memory of the episodes within 30 minutes, I don't think that they are something that you should worry about. That being said, apparently your Mother's disease and symptoms are slowly getting worse and you need to adjust your thinking and your response accordingly.

My own Dad would experience what is called "sundowning" where he would get into his time machine and go back to the 1940's. Dad was living in senior living and he would call me saying he was late at work because of a meeting thus he missed the bus to come home, so he will stay at the hotel.
Well, the last time Dad took a bus to and from work was back in the 1940's, and the hotel he was staying at was his Memory Care apartment. I found it was better to just play along with him, not try to convince him it was 2016, as that would only make him upset.
