Response to commentaries by Karin Rolanda Jongsma and Suzanne van de Vathorst, and Oliver Hallich

The authors of the two commentaries raise some interesting and important objections to my paper, 'Advance Consent, Critical Interests, and Dementia Research'. In my response I try to show that the objections raised can be understood as general objections against advance directives, rather than against research directives in particular. Since my main argument in the paper is that if we accept advance directives for treatment then we should accept them for research, arguments showing that we should not accept advance directives at all are consistent with my point of view.
