During the earlier stages of the disease, the person may only need a reminder to bathe. But as dementia advances, he needs more assistance. And here is where the problem arises. Having another person telling him what to do or assisting him inside the bathroom makes him feel like being tampered. And so, his initial reaction is to resist the instruction to bathe. He will either claim to have just showered or that he will do it later. But, in many cases, the person with dementia will outright refuse to take a bath. As he is defiant, you can expect him to argue and cry.
