My mother doesn't like to wear pants. Is this a behavioral problem, or a sensory/health problem?

lynnrhoads, if your Mom use to wear slacks in the past, as againx100 had mentioned in her posting, it now could be too hard to put them on.

I know as I have aged, I had to change my dressing routine. No more standing up to put on slacks, needed a third arm to do that as one arm is on the wall to keep me from falling over, and pulling up slacks with the other arm wasn't easy :P

Now I sit on the bed to do the slacks. And learned not to wear fuzzy socks when doing slacks, otherwise those fuzzy socks will make it difficult to pull up the slacks or to take off the slacks.

Oh getting older is soooo much fun :]

This is the Dementia. She probably wore dresses all the time when she was young. I really believe as the Dementia progresses, they go back in time. Just buy her some dresses. Not sure if they still make house dresses. They are easy to get on and off.

Just a sample

How old is she? Does she live alone? Is she diagnosed with dementia?

Maybe the pants are too hard to put on? Maybe too challenging when she needs to use the bathroom? Would she wear a house dress? Or a robe that would also give her some kind of coverage?

Maybe you can observe her and ask some questions to try to figure out the source of her pantslessness (to coin a "word"). This could help you to "solve" the problem if you can understand the big why.
