Mum finds it difficult to form sentences now, and many words will be swapped for a made up word so it is really difficult to have any idea of what she is trying to say, add in that she hallucinates and will talk to other people and verbal communication during visits is much reduced. After a long period of her being sleepy when I visited, a new phase appears to have arrived where she is wide awake and singing - not songs but words and stories, persistently, to a made up tune. You can make out more of what she's trying to say when she's singing, less made up words, which is interesting. She also seems very happy when she's singing and smiles away looking quite triumphant She used to do stage stuff, pantomimes etc when younger so can hold a tune (but is very loud! ) I wondered if anyone had come across this? I'm glad she's in a happy phase.
