I had this with a couple that lived upstairs from me. John who was about 900 (the boyfriend) knocked on my door at 8am just as I was leaving for work, insisting he’d just arrived home from national service in greece, and needs to pay me money for rent and then go and renew his papers. Erm, second world war posting…
So, I took him back to his flat, and got the senile old woman up too to make sure she’d take him in, but he didn’t recognise her. But she let him in anyway.
Then, about a week later, she had a fall and was taken to hospital, and about a week later at 4 am he decides to try and get into their flat again, and was banging on all the doors and screaming for the woman to let him in, but she obviously wasn’t there. So, I gave the police a quick ring, explained the situation and they came and helped him away. Sadly, the old woman died shortly afterwards, and I’m not sure what happened to John, but not seen him since.
I think you have to be patient with this woman, and help her as best you can. If you can get her chatting and find out the details of any next of kin, give them a call. It’s only if it happens at odd hours that it gets different.
But, apparently these old people with dementia are in demand from historians and the like, as whilst their current memories are fading, they’re able to be remarkably lucid about events that have happened in the past and can provide personal accounts of these.
