Meds can make take almost all symptoms away for some people - the right med anyway. And finding the right med can be quite a challenge. What works for some, doesn’t work for others. It can work for you for years, then stop working. It can look like it works at first - then stop after a few weeks.
My son spent most of the past year just like those videos. He’s on a new drug now & while he’s not completely well, he’s improving and pleasant to be around. He’s no longer paranoid, but he does have problems going out in public sometimes and he still has some of his less troubling delusions.
Since this sounds like it’s fairly new for your wife, please make sure they rule out other things before they slap a paranoid sz diagnosis on her. There are physical problems that can mimic SZ including thyroid issues, certain infections, etc. I don’t have a comprehensive list, but I’m sure one isn’t too hard to find.
The psychiatrists might not be too interested in running all those tests, but a good family doctor or internal medicine doctor might have some ideas.
I’m sorry you’re the center of her paranoia. For my son, it was his father and a few other people - luckily, never me - but I’ve worked hard at developing his trust.
Even though you have no “legal” authority, and if you haven’t already tried this, contact her HR department and act like you have the authority. You might get somewhere - and if you don’t, you’re not any worse off than you already are.
I do all kinds of things for both my husband & my son that I don’t have any legal authority to do - not that they wouldn’t give it. I just act like I do (because I truly believe I should be able to do it) until someone says no. I don’t hear no very often.
You may also be able to ask for a family meeting in the hospital even if she hasn’t signed the form that allows them to talk to you.
By the way, I mentioned my son was like those videos for a lot of the last year. It took 5 involuntary hospitals, enough non-compliance to get him on Invega Sustenna, and then to have the Invega Sustenna fail enough times to get him on another drug - but along the way, he became compliant and is doing well.
