 I call it the dilemma of the changing me, because let's assume you have a patient that has been very interested in literature, in politics, in classical music, has enjoyed all of his life. For his family, that's their dad. And then he becomes into the advanced stages, and he is suddenly also enjoying folk music or a game of bingo, which he would never have done when he was younger. And then the family suffers for their former dad, the man with the classical music and the literature.
