My dad is 84 and has dementia although he was never diagnosed. He stayed with me for 7 weeks recently, his short term memory is very poor. Long term memory is good. I just took him back home in May and his wife placed him in a home. I called his care manager who said he is very anxious and they are giving him meds for it. She said he threw poop in his room. Why? He never showed such behavior while with me and my family for 7 weeks.
He has never been diagnosed. Do you have any idea whether he is suspected to have ALZ, or vascular dementia, or Lewy Body, or FTD? That doesn't really change anything, but it might (perhaps!) give you a better idea of what to expect as the disease progresses.
If he'd stayed another month with you perhaps this behavior would have shown up at your house. What has his wife been experiencing that led her to place him in a care center? Is the care manager someone at the home?
It is so hard to have a loved one with dementia!
I think it was great that you took care of your Dad for 7 weeks, to give his wife a much needed break. Apparently she found it more difficult than she could handle so that is the reason why Dad is now in a continuing care home. As one ages, we just don't have the energy that we had just a few years prior. Seniors caring for seniors is physically and mentally exhausting.
I bet even if you brought Dad back with you now to your home, you will find that his memory has failed even more, and that he is now incontinent.
Btw, my FIL, 86, thinks his wife is fooling around with one of the employees at his NH. He was the one who always ran around.
Because he has dementia.
