The Limited Value of Dementia-Specific Advance Directives

Many people are worried about developing dementia, fearing the losses and burdens that accompany the condition. Dementia-specific advance directives are intended to address dementia's progressive effects, allowing individuals to express their treatment preferences for different stages of the condition. But enthusiasm for dementia-specific advance directives should be tempered by recognition of the legal, ethical, and practical issues they raise. Dementia-specific advance directives are a simplistic response to a complicated situation. Although they enable people to register their future care preferences, in many cases, those preferences will not, and should not, determine their later care.
