I don't know if its the weather or the fact I have just noticed but when my mum gets slightly agitated she starts to spell words, but ones that don't spell anything or mean anything, they probably do to mum but to me I haven't a clue and when I ask she doesn't know what they mean or why she is spelling? Should I be worried or just let it go as another dimension to the Alzheimer's (I will check her urine just incase its a UTI doing this).
