We have a family member who is cleaning and moving my mother n laws personal belongings to different areas of the home. when she asks for someone to get them for her and they are not where she put them she gets upset and seems to get more confused. Should her personal belonging be left she kept them.
Someone else mentioned moving things around for fun. I agree this is cruel, especially if an expensive table for instance is replaced with a cheap one and put in the same spot. I saw a sad story on TV many years ago about this very kind of thing that happened to a retired judge who went blind. I don't recall how long it was before he noticed something different about the new table, but I think it was his female caregiver who was coming in to his very comfortable luxury home and caring for him. I don't recall how many other people she did this to, but I think there were others with similar things like this happening to them. I don't recall who got the authorities involved, but the person was exposed and I think was eventually taken into custody. To move something on someone is one thing because the item is still there though the blind on or may not know where. However, what's even worse is to have something of value stolen only to discover it when the person who stole it is long gone and possibly even the property. Once the property is gone, it may be sold and the person buying it is unknowingly buying hot property. I don't recall if property already bought by a new owner is ever recovered, but I think this would be the right thing to do. If stolen property bought by a new unsuspecting buyer, a full refund should be given when the property is recovered for return to the rightful owner from whom it was originally stolen.
Now, getting back to moving stuff, I noticed someone mentioned grandkids coming in and having to move something to sit down, this is fine as long as you put the item where it was before leaving. That way, there is less chance of that demented elder getting upset because the item is already in it's usual spot. Sometimes when things are laying around, it's absolutely necessary to move something so you can sit down when visiting, so please remember to put things back where you found them before leaving. That way, everyone is happy later. Courtesy always pays off.
If you have someone coming in to clean the home for your elder, make sure they understand how to put things back right where they were and explain why. Perhaps someone may come in who has no experience whatsoever with dementia or Alzheimer's patients. I know that in order to gain experience, you must start somewhere and maybe even having experienced people guide you as you're learning along the way. If you must move something to clean around it, always put things back whether or not the person has any form of mental decline, this is the right thing to do.
Routine was also mentioned here. Routine is good for anyone who feels comfortable with it, demented or not, routine is good. My foster dad had a routine. Not everyone has a particular routine, but some people do whether or not they experience dementia or Alzheimer's. Routine may be most helpful for suffers of memory loss or other mental decline because for some, change can be very traumatizing and also very confusing.
I must admit that even if you don't have any form of decline, sometimes changing even a normal person's routine when they're used to routine can be very upsetting, even downright angering. I don't have any particular routine, but I might occasionally adopt at very least a temporary one for a while. When I get good and comfortable and someone steps in the way, it can make me a downright angry depending on the situation. Routine can be very good for anyone if there happens to be something that draws you to routine. Routine is not necessarily for everyone, routine can actually become very tiring and very draining.
There are many, many good suggestions here for you. Good luck!
So...short and simple if possible leave all personal items where they belong and where the person is more apt to be able to retrieve them. Hard enough to not get frustrated when you misplace something let alone someone moving things.
If things have to be removed that is one thing but other items that pose no danger should be left alone.
If this relative who is doing the cleaning has some problem understanding this simple concept, then I hope you can hire a cleaning person who will do as instructed.
Sometimes change is inevitable. I had to completely rearrange our bedroom when a hospital bed was brought in for my husband. By moving objects we made it possible for me to continue to sleep in the same room with him. That was a higher priority than keeping all the objects in place. Plus he needed a lot of new objects in that room.
Sometimes objects need to be removed because they now pose a risk.
We can't always keep everything exactly the same, but things should only be moved for well thought-out reasons.
