I mean the person still IS who they are only ...changed. Looking at my BIL with stage 4 Alz. I still see my BIL he's not someone different. It's sad but he is still here body and soul- his mind is somewhere else, but he still is my BIL not a stranger. I might be wrong about all this it's just that if my husband or myself would get this disease I would like to know that we would still be Dad, Mom and not the words, "That's not Dad, that's not our Mom anymore." Guess this thought came from reading the poem The Long Goodbye.
