It's the room size rather than clutter that causes that issue. We need to move anyway as we are in a first floor apartment that suited when we were in Cyprus so often but we now need a bungalow because of mobility and other issues that are creeping in as Mrs B's dementia progresses. I think the writing may be on the wall for a move. The local care team arranged some aids like handrails for her but it won't be enough in the long term.You might find a bigger/bit more space when you've decluttered.
