Listen carefully to a person with Alzheimer's as they lose language. Tonight George's caregiver was taking something through to the bedroom for him. George wanted to say 'are you carrying that in?' instead it came out 'Gunga Din'.
I often find I can work out what he is trying to say as I have a reasonable idea of what he would have said. The caregivers at Mum's home often used to ask me how I knew what she was saying. As I said to them I guessed the types of things she might say and if I didn't know I pretended I did and watched her body language for clues, I do the same with George.
