My dad has always had a bad attitude and he is always fighting with everyone around him. I think it’s best for him to live somewhere else. It is also very stressful for me to go to work and have leave him alone. He doesn’t want nobody to come to the house and take care of him. He says he is doesn’t need to be taking care of.
As far as your dad living alone, that is not a good idea at all. Dementia is a progressive thing........it worsens with time and reaches the point where they can and do become a danger to themselves by trying to cook or getting into chemicals under the sink. They all wind up needing lots of help with daily activities of life after a while, even those that insist they DO NOT. They do. They need meals prepared for them so they don't burn the house down, at the very least. Help with bathing, down the line, and other things that may not be obvious now, but will be later on.
Wishing you the best of luck finding alternate living arrangements for dad.
If there is no formal diagnosis, you need to get one. His PCP should order labs to check his potassium levels, thyroid, etc. If found nothing physical, then he should see a neurologist.
Even in the early stages, a person suffering from Dementia should be monitored. Decline can literally happen over night. My nurses called it an "episode". Dementia is unpredictable, a problem I had with it. Not saying Dad can't live on his own, just be aware that Dementia can be a slow decline or a fast decline.
Get Dad a good physical first to determine what kind of care he needs. If he has money, an Assisted living may be good. If he is low income, there are subsidized HUD apartments. Where I live they r pretty nice. Handicapped accessible. Common area to socialize and activities. Our local transit bus stops for pick ups. Can also get the Senior bus. Ours is in walking distance of a grocery and pharmacy.
It maybe hard to place him in LTC. Dementia alone does not get you in. You need to show you need 24/7 care and help with ADLs.
When was he diagnosed with dementia? I need more information.
Sound like you have had enough, and that's ok. Being a caregiver for a loved one can be very difficult, and especially when they're constantly negative. You have to do what's best for yourself. Your dad will be just fine in whatever facility you find for him. Best wishes.
If he does not want anyone to come see him, maybe put a camera in the house and get a wifi connection so you can monitor him.
If he moves out who pays for the move, his own place? Who is going to move him and his stuff? How far away will he go?
Whatever you do it will only be temporary as he will eventually need care/help. So if he does this you should start planning for that event.
