We recently moved my 82 year-old father-in-law in with us. He was showing signs of mental decline, but I think it's far worse than we thought. He already believes we've stolen his life savings because we took his checkbooks from him to lock them up (he kept misplacing them and then panicking and accusing everyone of stealing them. He would also write checks for thousands of dollars and then not know where to send them because nothing was due, but send them to random companies). He truly believes his money and CDs are gone since he doesn't have it in hand, has lost all concept of a bank.
When we went to clean out his house, he couldn't find the CDs (paperwork for the CDs that we already took to our house) and swore up and down that some kids broke in and stole them. That was the only possibility. I tried to assure him that they wouldn't be able to do anything with the paperwork because they aren't him or my husband (his attorney in fact), naturally, he didn't believe me. Then, as soon as we got home, I showed him all of the paperwork, but all of that was forgotten the next morning. Then, as we were leaving his house after cleaning, he was concerned that kids would break in and turn his water on and steal his food (food we left until we brought a cooler back).
Effective July 1, 2019, he has Medicare Parts A, B & D, yet he doesn't believe he has insurance since he doesn't work (he was working all the way until 7/1/2019 at a grocery store). His PC Physician, other son and daughter-in-law, multiple nurses, his cardiologist and phlebotomist have all told him he has Medicare and it's really good insurance. He believes no one - they don't know anything. Then, he'll say that it doesn't pay anything and that he'll be broke. He is combative when going to the doctor and when taking meds. By the way, any tips on giving him his meds? He firmly believes we are trying to give him a stroke or paralyze him, if not trying to kill him. I explain that he has to take his high BP meds and blood thinners or he WILL have a stroke or heart attack. He doesn't believe us. For example, it took us 45 minutes to give him his night meds last night. This morning, my husband spent an hour and 4 minutes. We really don't know what to do. We can't just let him go without his meds, but he's becoming more combative and once they melt in his mouth (he holds them in his mouth until they do), he will spit everything out. Any tips? Clearly, we need all the tips we can get. :) Thank you all.
