How can I get my uncle into a locked facility against his will? He has alcohol induced dementia and I can't stop him from drinking.

Hellrazor— this is such a sad situation because unfortunately there is nothing you can do unless he becomes violent with you, then call 911. EMS could take him to Er, that is, unless he refuses to go with them. He could possibly benefit from an alcohol recovery program, if HE really wants to quit and there lies the million dollar question….,
you cannot change him or his habits. Who buys his alcohol? Is he driving while intoxicated? If so, I would call 911 every time and hopefully they can pull him over and arrest him if he is under the influence. Please don’t let him kill an innocent family if he drives drunk. Call his local police or sheriff and ask them what to do, they could advise you. Under no circumstances buy his alcohol for him. You could call APS and anonymously report a vulnerable alcoholic elder. You should back away from this situation…..,prayers for you. Liz

I had a brother who developed alcohol induced dementia. There is nothing you can do. I suggest Al-Anon. It helped me.

You can't have his recovery for him. You're not responsible for his happiness. You need to put up boundaries so his radioactive choices don't start to burn you. There is a solution for him, but you don't like it: leave him alone with his choices and when it gets "bad enough" the county social services will intervene and acquire guardianship of him and legally place him into a facility. You can go visit him there all you want from the safety and sanity of your boundary. I'm truly sorry but you have no power in this situation. Wait for the solution.

Unless he has been declared mentally incompetent by a Court, there is nothing you can do. He is a free man who can drink himself to death like many others who are dependent on alcohol or other addictive drugs. Only condition to force him into a Mental hospital is if he becomes dangerous to himself or to others. That means becoming suicidal or homicidal.
