I'm traveling an hour helping my husband with his Mother. I have to lock my bedroom because my father seems to think he can let himself in to go through my things. Breaks things on purpose. Now I recently went back home to find my bedroom door broken into. If I ask him about it, he'll claim not to know anything about it. Even though he's the only one home. I don't want to place him in an assisted living, however, I'm frustrated and know he's doing thing to push my buttons to start yelling about this. I Pray and keep my peace and calm. He finds ways to try to upset me to get a laugh out of it. Don't know what to do at this point. There's no one else to care for him.
I wouldn't bother talking to him about it as nothing is likely to change. Perhaps he should not be left alone since he is destructive?
Maybe he needs some meds? Or maybe you need some outside help?
Best of luck!
Dementia means that there is brain damage. They can't be expected to go on as usual or to respect your boundaries or behave the way you want. I would caution you about safety, because sometimes people with dementia act in ways that are not in keeping with their normal self. I'd remove weapons and sharp objects from the house. And, I'd make a safety plan, even if you don't think you'll need it.
Also, laziness is not really something that comes into play with people who have brain damage. They lose their initiative to do things, so, keeping them active may be difficult, even with direct supervision. Eventually, they are unable to walk or feed themselves. I'd be cautious of leaving him alone. Except for the early stages, people who have dementia cannot be left unattended.
I'd learn what to expect as he progresses, so you can make plans for the future. If you don't have someone to help you, you may need to explore outside help coming in or a facility, like Memory Care. Caring for someone who has dementia is a huge responsibility and a lot of work. I hope you can find some help.
