A Dementia Directive is an increasingly popular tool for individuals to communicate their medical preferences should they develop Alzheimer's or another form of dementia. Unlike standard advance directives, which often lack detailed provisions for the gradual decline associated with dementia, these directives specifically address the complexities of care in such situations. They can be created as a standalone document or, more commonly, as an addendum to an existing advance directive, providing more specific guidance for healthcare agents and physicians. These directives are particularly important for people over the age of 60, due to the increased risk of dementia in this age group, and should ideally be completed while an individual still has full capacity to make medical decisions.

The development of the Dementia Directive was a collaborative effort, involving experts in neurology, geriatrics, and palliative care, led by Barak Gaster and his colleagues. A free version was released in November 2017 and has seen widespread adoption, with over 100,000 downloads to date and continuing at a rate of over 2,000 downloads per month. While not legally binding, these directives serve as a crucial guide for discussions between family members, healthcare agents, and medical professionals, ensuring that decisions made on behalf of the patient align with their stated wishes.

Completing a Dementia Directive allows individuals to articulate their preferences for various aspects of medical care, including how they wish to be treated when they can no longer understand risks and benefits of medical decisions. It helps alleviate the difficult decisions families often face by providing clarity about the patient's desires. The document encourages early planning, as it becomes challenging to complete once signs of cognitive impairment begin to appear. It's also recommended to discuss these wishes with close family members and healthcare agents to ensure everyone involved understands the outlined preferences.
