My dad has Alzheimers. He doesn't know for sure if he has to have a bowl movement and he can't go by himself . At least 10 times a day he says he has to go but only passes gas. Even when my mom (who has to help him remember how to get on the toilet and wipe his butt) tells him he's already gone to the rest room, he insists on going approx 10 x's a day!! When he's not on the toilet he's talking about it (or tries to talk about it). Is this normal for a person with Alzheimers?
