If she's a danger to herself -- injuries due to falls, fights/struggles with others, unable to distinguish between hot and cold foods or liquids, strays -- the placement is something I'd consider.

Is there someone who can convey and get it across to her that it's not appropriate to disrobe for no reason (in a way that she can understand)? I can relate to that; the person I'm caring for was doing the same in restrooms. The "logic" part of the brain doesn't work the same any longer.

Despite the condition someone is in, I still think, they also want to retain their dignity, so I don't "follow" in the stalls, etc., but do make sure nothing ill-will will happen.

When no longer safe to be at home, that's when I'd make the call.

Too, I would let the agency or facility (coordinating care) know that you really do need to be kept informed on how she fares with her care and her care-givers.
