Dad lives in assisted living with moderate dementia. If I take him out for lunch and errands he tells me that he has to pee. We can be gone 3-4 hours and he will go to the bathroom about once an hour. I do not follow him into the bathroom to hear if he actually pees or not. He does not complain of any UTI symptoms. He is 86 and I do not think he drinks a lot of fluids unless prompted.
