Abstract
Nutrition and hydration—including artificially delivered, or assisted, nutrition and hydration (ANH)—are typically considered ordinary or proportionate care in the Roman Catholic moral tradition. They are thus morally obligatory, except when the benefit to the patient does not justify the burden their administration places on the patient or when they no longer prolong life (e.g., in end-stage disease when death is imminent). A review of Church documents and the medical literature provides convincing evidence that there are cases in which ANH provides little hope of benefit and may impose an excessive burden on the patient. This paper closely examines advanced dementia of the Alzheimer’s (DAT) type and shows how ANH can be properly considered extraordinary care and hence is not obligatory in patients with advanced DAT.
