My mom is 82 and has been having increasing dementia issues for the past few years. Nine months ago, one of my sisters moved to live with her in the house she has been living in Green Valley, AZ for the last ten years. About a month ago she had a fall and ended up in the hospital. After the hospital, she was in a rehab center for a couple of weeks. Since returning home, she has taken a sudden turn for the worse. She is becoming incontinent, but the strangest thing is that she keeps insisting that the house she returned to is not the house she remembers. She thinks she is living in my sister’s house and not in her own house and keeps asking to be taken home. She insists the “old house” was up at the top of the hill (in the center of town) and now she living out in the boonies at the bottom. Is this usual for someone with dementia in the situation I described (brief hospital/rehab stay)? What might have triggered this? Could this have been a result of the fall and not the progression of her dementia as such? Although the CAT scan she had done did not show anything unusual. I know this must sound like a naïve question, but it is so strange to me that she doesn’t recognize her own house after being away for such a short time. My heart goes out to her in her confusion and I wish I could say something that would jog her memory. I was just wondering if anyone else has had an experience like this and if you have any advice on how to best deal with it. Thanks!
