My brother began acting strange about 6 years ago. It started out with him thinking that people were 'after him' and has progressed so much that he is completely antisocial, doesn't work, he has been Baker Acted 2 times for a suicidal threat and attempt, he thinks the government is after him, thinks there are speakers hidden in his furniture, we have caught him chanting (not in any real language) and writing strange non-sensical notes. He has false memories of when we were children. He believes doctors are trying to control him and drug him. Our family has tried to get him to seek therapy and/or drug treatment, but he refuses. Over the past couple of years, the irises of his eyes have darkened and now they are almost black. I can't find any reason for this...he has not been on any long term drug therapy. I also cannot find a way to get help for my brother as he is an adult (in his 30's) and he refuses care. We live in Florida and even when he was Baker Acted, the doctors and nurses would not even listen to our accounts of what had been going on with him because he is an adult, and he was released after 72 hours because he told the doctors he was fine, even though he wasn't. He lived with our father for a couple years, and rarely came out of his bedroom. Now he has decided our father is trying to kill him and is moving back in with our mom. He is 32 years old, 6 feet tall, and about 180 pounds. He has no medical issues (other than this). Is there anything we can do? Is there any information you can share? Thank you.
