She's been fairly settled at my mum's house for a few months now, but recently she seems to be more agitated and unsettled. She was checked for UTI and had a blood test when she wandered to the local hospital a couple of weeks ago and all was well there. Today, out of the blue she tells my mum she needs to go to the newsagent to get Shaun the Sheep (?). In the end, she wandered down to the local Tesco corner shop and came back after about an hour. Just had a call from my mum and she's now announced she has to go to New York (!). So my mum's a bit concerned now it's dark and this is a destination she's never spoken about before, so we haven't got a clue how she thinks she's getting there tonight. We have conversations all the time about whether my mum should just lock the front door and hide the key, but she's concerned about the agitation that will cause. The official advise is to let her go out as she still has capacity and isn't considered a danger. When we have episodes like this one, I find it difficult to know what the best advice is to give my mum, other than what I've told her before and that's to let her go if she's getting so agitated that my mum feels threatened. I've told her to say that all the planes to NY are cancelled because of fog, but I don't know if this will work. Anyone got any other bright ideas?
