My wife is in year ??? 8 or 9 with MCI diagnosis and for the past couple of years she rearranges the kitchen cabinets, drawers and pantry and refrigerator, often if I'm gone for a few hours. I do all the shopping and meal preparation and I often cannot find what I need, and of course she has no memory of where she put things. There is no logic to how she rearranges, other than sometimes by shape, or color or size. And she creates "space" by putting things in the very back of the pantry compartmenst (where I cannot see them without moving things in front of). She rearrange all my toiletries and personal items below my bathroom sink (not a shared area---she has her own drawers and undersink space). She rearranges what she has already rearranaged sometimes and when confronted, has no memory or denies doing it.
