In case of dementia, a conflict may arise between the formerly composed advance decision in which the autonomous will of a person is expressed, on the one hand, and the “natural will” of the person while suffering from dementia, on the other. Decisive in this conflict is that the person suffering from dementia can merely express her current will without having the capacity to form an autonomous will. De facto it is shown that the “natural will” is assigned a great importance, since the long-term well-being of the patient is central, whereas from a legal point of view the autonomous declaration of one’s will is assigned a greater value. Whether we should attach more value to the earlier autonomous volition or to the natural current will is a subject of controversial ethical debates.
