My mum constantly repeats letters over and over. She is able to have a conversation between, but as soon as the conversation stops she starts repeating letters over and over again. Sometimes it’s sentences but mostly just letters. Each day she seems to have a selection of 4-5 letters which she repeats over and over. She doesn’t seem aware that she is doing this, on the odd occasion I’ve mentioned it and she either doesn’t know what I’m talking about or says something like ‘I must be trying to sort my mind out’. I don’t think she really knows what she is doing. Should I make her aware when it happened or just let her carry on?
