Margaret Thatcher, former Prime Minister of the United Kingdom, has passed away. Her daughter Carol first revealed that her mother had dementia in 2005, saying that 'Mum doesn't read much any more because of her memory loss .. It's pointless. She can't remember the beginning of a sentence by the time she reaches the end.' She later recounted how she was first struck by her mother's dementia when she muddled the Falklands conflict with the Yugoslav wars; she has also recalled the pain of needing to tell her mother repeatedly that her husband, Denis, was dead.
