Commentary on SA. Terman, KE. Steinberg, and N. Hinerman, "Timely dying in dementia: Use patients' judgments and broaden the concept of suffering"advance directives, AMA code of ethics, dementia, deterioration, Nancy Rhoden, Norman Cantor, Rebecca Dresser, suffering, then-self versus now-self problem, withholding food and water Terman, Steinberg, and Hinerman 1 argue that at both the planning and implementation stages of advance directives (ADs), the use of a broader than typical concept of suffering can help accomplish the goal of not living into prolonged years of severe dementia. For both practical and fundamental ethical reasons, this strategy cannot live up to its promise.The authors are to be lauded for working to make ADs for hastening death in dementia more effective.

There is no "objective" clinical test for it. Since there is not, clinicians should use patients' judgment.

(3) Both the construal of suffering by Cassel to include the eroding of "integrity" in a person's life and Saunders' conception of "total pain" are insightful expansions of how to understand suffering. 2 (4) Many patients with advanced dementia have difficulty communicating their suffering. (5) ADs need to speak clearly not just to what care should be withheld, but to when it should be. (6)Patient appointment of a health care agent is an important complement to any instructional AD. An agent's leverage in representing the patient is hampered when there is no AD to serve as a guide, and an AD without a patient-chosen agent can languish in the face of inevitable ambiguity and difficulties of interpretation.Notwithstanding these strengths, the authors' effort has a central flaw: it is not just unacceptable suffering that many patients with pro-This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
