Dispelling Medico-Legal Misconceptions Impeding Use of Advance Instructions to Shorten Immersion in Deep Dementia.

Abstract

Progressive dementia afflicts millions of people, ultimately entailing precipitous mental decline and years of complete dependence on others. Many people deem the prospect of serious cognitive dysfunction, helplessness, and dependence to be intolerably degrading (as well as overly burdensome on others). To avoid being mired in prolonged dementia, they prefer to hasten death by advance instructions rejecting life-sustaining medical intervention at a point of decline they define as unacceptable.Some health care providers resist implementation of such advance instructions, especially as applied to patients with dementia who are not ostensibly suffering in their demented states and no longer recall their prior instructions and the dignity concerns that underlay them. The clash between advance wishes to hasten death and some health care providers' preference to maintain the well-being of nonsuffering patients will be surfacing, in coming years, in institutional ethics committees, professional disciplinary forums, and the courts. This article defends the legal and moral status of advance instructions seeking to shorten the unwanted limbo of deep dementia.
