Sounds like it is the difference between *habit* and *new* noises and pictures......the toileting thing will be an ingrained habit , learned over a long period and doesn't possibly require any thought process'. Whereas the sounds and pictures his brain receives are all viewed as *new* and therefore disturbing.
I think the same thing happens with severe amnesiacs ...they remember they need to use a loo for bodily functions but do not remember their familes or places ....
Hoping you continue to see improvements daily {{{hug}}}
