Alzheimer's, Advance Directives, and Interpretive Authority

Area of Science:

• Bioethics
• Philosophy of Medicine
• Neuroethics

Background:

• Advance directives for Alzheimer's patients present ethical challenges regarding enforcement, particularly when patients appear content in a demented state.
• Existing philosophical debates often assume clarity in advance directives, overlooking practical ambiguities.
• The role and interpretive criteria for healthcare proxies acting on vague directives remain underexplored.

Purpose of the Study:

• To explore the philosophical criteria healthcare proxies may use when interpreting vague advance directives for Alzheimer's patients.
• To defend a normative policy for enforcing advance directives, even in cases of patient contentment during dementia.
• To address the ethical implications of proxy interpretation on patient well-being and autonomy.

Main Methods:

• Philosophical argumentation and conceptual analysis.
• Examination of ethical principles related to autonomy, personal identity, and advance care planning.
• Normative defense of enforcing advance directives.

Main Results:

• A general policy of enforcing advance directives is defended on normative grounds.
• When advance directives are vague, proxies are permitted to conduct a fresh evaluation of the patient's life.
• This evaluation can include assessing the contribution of the patient's demented state to their overall life quality.

Conclusions:

• Advance directives for Alzheimer's patients, even when vague, should be enforced.
• Healthcare proxies have a permissible role in interpreting these directives through a holistic life evaluation.
• This approach balances respect for prior wishes with the complexities of cognitive decline and patient well-being.
