He is 59 years old, diagnosed schizophrenic (which is controlled by medication) and is also diabetic. He receives disability and is living with another male who is addicted to pain pills and who does not care for my brother well, feeding him sugary foods and beverages all day long, who does not ensure that he takes his medications, who does not ensure he eats healthy foods, and who does not make sure that he is bathed and wears clean clothing. My brother's partner/caregiver is only concerned with where he will get his next round of pain killers often showing up at the local ER to beg for medications. I would like to move my brother someplace else, where he will get better care, but don't know whether he is a good candidate for assisted living and, if he is, how to go about extracting him from this negative environment he is in, and moving him to assisted living.
You said his illness is controlled by medication but then you said he doesn't take his medication. If he's happy where he is leave him be. He found someone addicted to pills and now they live together. He did all of that on his own, I have to think that he's capable of doing other things on his as well, he just may not want to.
However, if you really want to get in the middle of this his Dr. can refer you to a social worker.
But I hope you leave him be.
