My wife has Alzheimers, but she still likes to go out for a meal. She needs help in going to the bathroom and the occasion hasn't arisen yet, but how do I approach the restaurant staff to go in the female bathroom to assist her? I am thinking this is the same as a physically disabled person needing help with that function.
I think I would go with the suggestion above about asking for a private bathroom where you can go in and help her uninterrupted. Some places have a handicapped separate toilet in it's own room. I might call around and find a few like that so you know before arriving.
(Going for a bit of humor, here .. no offense meant)
