My 87-year-old mother is constantly washing and rewashing clothes. She wears the same outfit almost every day and some days will keep her pajamas on all day. But there are always piles and piles of laundry up and down the hallway, in the dining room, in the kitchen, and in the laundry room. You would think she was washing clothes for a 10-member household. And no, we do not have a large family, nor did she when growing up. Many of the clothes are summer items and it is now winter and cold outside. We are mystified by this behavior.
Washing and rewashing over and over, week after week. Other than an obvious tripping hazard, should we be concerned? Is this a sign of dementia?
In your case, and like others have said, just pack up those clothes that are not in use. Repetitive activities are part of the dementia process. The brain is broken. Redirecting of activities may be a help. Sometimes the brain gets caught up in a loop.
Other than that, is she bored? Can you substitute another activity for her?
Does she do any other things in a repetitive manner? Have you noticed that her memory is not as good as it was before?
Have you considered taking her to a neurologist for testing?
Can you please provide more information?
You do not give any information in your profile so I am going to ask...
Does mom live with you? Or does mom live alone? Or with someone else?
From this question and the one you asked previously, it does sound like there is something going on and she should be seen by her doctor. All the "quirks" that you have noticed recently, or even over the past year should be mentioned to the doctor no matter how silly or trivial they seem.
You might want to fill in more info on your profile so you will get better more accurate responses.
