Hi, you are welcome. We help one another here for support.
Also the patient has sundowning. I don't know if you have heard about it:
In the early/moderate stage, they get more depressed at sunset. They get more fuzzy at sunset. So the best thing to do is to keep him occupied in the day earlier. Then he may get tired and settled down at sunset. Eating supper around sunset (5pm) is a good idea.
Turn on the lights so the room is not dark - he would be afraid of darkness.
Lighting helps (as the sun is up) and he would feel more secure.
My FIL had had sundowning for a long time. Not that he does not have sundowning now. He is sicker now and cannot walk on his own, so the sundowning is not obvious with him now - he is sleepy and tired... He has dinner at 5pm everyday.
You have done so well!
Take care,
Nina
