My father developed paranoia psychosis, I need help figuring out what to do
My dad is 61 and retired two years ago, he had a tough job. .We moved countries a lot because of his job and he handled life normally for decades. Six months after retirement he was still social, always wanted to go out, travel, meet people, do things.
All of a sudden one day, about 1.5 years ago something completely changed. He started thinking people were spying on him and trying to frame him. Normal sounds upstairs became “people torturing him.” Someone who visited our house became a “spy” in his mind. He keeps repeating the same things every day and no matter what we say he believes it completely. And tells that visitor is gathering evidence to frame him, even though it's been two years. He's annoyed that we don't believe him, and says that we will see one day when it happens. He is so stubborn and doesn't want to listen to us one bit.
Now he just stays in bed most of the day. If we even mention going outside or to a shop he panics and gets extremely restless. It genuinely feels like the light went out of him and I still can’t understand how someone can change this much in such a short time. He was physically fit, played a lot of sports, and had several hobbies.
He’s been on risperidone, olanzapine, sertraline, clonazepam, propranolol, and now Clozapine 75mg. We still aren’t really seeing improvement and dose increases caused bad restlessness and stiffness.
Has anyone gone through something similar? What can you do to help them, it's so challenging. Because he is in bed all day, his muscles are deteriorating, and if we try to take him for a walk its impossible. I hate to see my dad like this, I wish there was some cure for this terrible disease. We've been through three psychiatrists already, and nothing seems to be working. They all are trying to make him sleep most of the time and say that it'll take many years for him to get better he should just eat these meds. He's had more side effects from the medicines too. I don't believe that this is how treatments should be, it's just ridiculous. I'm desparate to hear anything from you all, thank you so much in advance for any suggestions.
