When I ask my mother how she feeling , she tell me her legs hurt her .
what going on in her mind , is her thoughts she kindly tell me , when I ask her what she thinking .
On a good day like today she tell me , she thinking about tomorrow at day center .
when she upset because she done something wrong in her eyes , because she finding it harder to go to the toilet herself she tell me she so stupid what wrong with me .
I don't tell her , because if only upset her more .
I just hope that when she at the stage your grandfather is in she has no clarity of knowing what wrong with her , so she feel safe in her world of her reality in her mind , because I would hate to torment myself thinking that she does know .
so from observing my mother over the years with her AZ/ VD , your only really no from they body language, if they
agitated , relaxed looking when all speech has gone .
PS
He can't really speak anymore and he looks puzzled.
Just like you say above he look puzzled so your reading his body language . so his looking at you with a puzzled look because he has no clarity of who you are .
Then another day , may be a good day for him , he has clarity of who you are.
