My Dad is 85 yrs old with Alzheimer's. I can ask him to take a shower & he replies "I already took one, " or he goes in the bathroom turns on the shower, doesn't get in, changes his clothes & comes out. I've gone as far as saying "phew, Dad you really are strong today!" Last night I sat him down & told him I was disappointed, and he asked why & I ask him why don't you like to shower? Explain to me, I was calm & just like we're having a good ole conversation. So he never answered me, but just stormed off to the shower mumbling. But he did shower! So when he came out I offered him a back rub, as a reward. It's so hard seeing my Dad this way.
