Dad tries to urinate in inappropriate places--- for example a trash can, even when a urinal is within sight. I theorize that he fixates on an imagined solution and is unable to recognize and switch to viable solutions. He can read from a book, yet doesn't process large printed signs on the doors within his condo. He can't find his own bathroom, but will pee on the carpet in a corner, on the garage floor, or even a chair cushion. He tries to be cooperative, but if you're not right at hand to intervene, it's very quickly too late. We suggest frequent bathroom visits, but of course he "doesn't need to go" until urgency strikes--- and rationality fails. Dad & Mom are 91. Any suggestions? Thanks.
