In the beginning of this year my 80 years old dad went to a hospital due to a broken back (after he fell of a ladder... and down some stairs), he was in pain and shock as he was presenting to the hospital so lets say he was not in the best mental state... The first few days after we got him his mobile phone and he settled in he - as we know him - texted via instant messenger and called frequently. Then, he got more and more disoriented while speaking and ignored texts or replyed with incomprehensible texts. As the situation were (covid and so on) we were not allowed to visit him in the hospital and where only able to call to the station, the nurses and the doctors... they all told us, that it is not that uncommon that we have to live with the fact, that older people have sometimes demenita. Hint: He didn't had any dementia before he fell of this ladder. Or any other mental problems. A few days later he got total delirious, and the hospital informed us that we had to prepare to give hime full care. It was a nightmare for us. After 1,5 months he finally was released, and merely a shadow of the man i knew. We found out, that he was heavily drugged with melperon and risperidon for nearly the whole time he was there. We slowly took him of the medication and now he is slowly gaining back his old self, drives again and is recovering... we are evaluating legal actions against the hospital.
