Loved one with dementia taking clothes off constantly: What do you do?

So sorry for you & your loved one! You might try having her wear a duster type robe or dress but put it on backwards w snaps not as easy for her to access.
There are several catalogue clothing companies that sell items for people w dementia, also those wheelchair bound and folks w atrophied limbs that make regular clothing difficult to get on or off. My mom had CBD cognitive basal degeneration which made her a prisoner in her own body. Her r arm and hand were clenched up tight against her body and it was very hard for nursing assistants to dress her gently. I ordered clothing from Buck & Buck and sone other online company - great quality, looked nice, items for my mom all attached in back w Velcro. She loved her new stylish clothes (I could see her eyes brighten up as she couldn’t speak or mid her head) and it was easier for all both dressing & undressing her.
Let me know if you want me to find name of other catalogue online company.

No I have not but my late father in law had brain damage following a tumor and often appealing to his child like mind helped. Everyone is different. He liked jigsaw puzzles. Blowing bubbles, pre school sorting toys, music boxes, colorful helium balloons might be worth trying just to occupy senses.

Also … read about the Eden project. A small pet or one of the ultra realistic might provide soothing.

Could she be having some other physical issues that are making her uncomfortable? Rash, fever or the like? Maybe she is trying to communicate something.

I remember as my mother in law got older she, formerly meticulous, couldn't stand to shower anymore because it felt like "sandpaper" on her skin. My sister-in-law had Parkinson's and couldn't stand the touch of a dress I sent her - it was a broadcloth, kind of crisp, material. Maybe it's a perception issue related to texture and she would tolerate something that felt more like a second skin.

There can be a “restless” component w dementia. If there is something the person seems to like to do that is not harmful to themselves, others, or property, maybe give them opportunities to do so. Brightly colored items, simple musical instruments or soft noisemakers, fidget items (check store 5 Below for such). Maybe matching brightly colored pairs of socks, or simply moving them from one laundry basket to another, looking at a picture book (perhaps a board book) or photo album, listening to favorite old music or singalong songs - activities like these may be soothing while providing something to do. Look online for sellers of “busy blankets” or “busy boards”. These are also called sensory blankets. There are even directions online to make a personalized one.

Consider Asking the doctor if a mild medication might help “take the edge off” any extreme restlessness.
