My mother (91) and exhibiting early stages of dementia really scared me yesterday. She refused any, food, drink, washing saying that the bible had told her that December 21 was a day when we must not come into contact with water. Normally fastidiously clean she refused to let the carer wash her or to wash her hands after visiting the toilet. She spat at me and called me the devil’s daughter. She is not at all religious and has never done anything like this before. She remembers nothing of this today and is back to normal but puzzled why she woke up hungry and thirsty. Is this sort of behaviour normal in dementia? Can I expect it to happen rarely? Regularly? Any advice or information would really help. Thanks
