Advance Directives for Dementia: A Complete Guide
February 03, 2026

Advance directives are the difference between guesswork and guidance. For people diagnosed with dementia, they are not a bureaucratic nicety but a practical shield: a way to record healthcare wishes, appoint a trusted decision-maker, and make sure those instructions are accessible when cognition changes. This expert guide explains why advance directives are vital in dementia, how to create them step-by-step (including fully digital workflows), and how secure vaults (e.g., the Evaheld Vault) ensure long-term accessibility, privacy, and family coordination. Along the way, we’ll anchor key points to authoritative resources—Advance Care Planning Australia (advancecareplanning.org.au), the National Institute on Aging (NIA), the Alzheimer’s Association (https://www.alz.org/), Palliative Care Australia (palliativecare.org.au), and Healthdirect’s (https://www.healthdirect.gov.au/) overview of an advance care directive.
Dementia is progressive. Even with excellent support, cognitive capacity tends to decline—affecting memory, reasoning, communication, judgment, and insight. The window for a person to understand, weigh, and communicate decisions is therefore finite. An advance directive—also called an advance care directive or living will—captures a person’s values and medical preferences while capacity is intact and nominates a healthcare proxy (substitute decision-maker) who can act later. The approach is endorsed internationally: early, values-led discussions; clear documentation; and broad sharing so clinicians and family know where the truth lives (see the NIA’s guidance on advance care planning and Australia’s national resources via advancecareplanning.org.au).
For dementia specifically, timely directives help with:

An advance directive (AD) is a legal expression of future healthcare wishes. It can include:
What it does not do:
For a plain-English overview and state/territory nuances in Australia, see Healthdirect’s (https://www.healthdirect.gov.au/) page on advance care directives. For dementia-specific considerations, the Alzheimer’s Association (https://www.alz.org/) provides an accessible primer on advance directives.

Begin with what matters most, not with procedures. Use prompts:
Write a short values statement in your own words (2–6 sentences). This anchors later choices when particulars get messy. Advance Care Planning Australia offers conversation guides and forms to help start and structure these discussions (advancecareplanning.org.au).
Tip: If memory is already fluctuating, record a brief video statement alongside your written directive. This humanises your choices and helps proxies advocate with confidence.
With dementia, decisions often centre on:
The Alzheimer’s Association outlines common scenarios and how to record healthcare wishes that reflect personal goals (https://www.alz.org/). Palliative Care Australia provides a values-based frame for relief of suffering, dignity, and family support across settings (palliativecare.org.au).
Keep language conditional and contextual (“If I am in advanced dementia with no meaningful interaction…”). Absolutes age badly; scenario-linked preferences age
better.
Pick someone who:
Have a dedicated conversation with your nominee. Share your values statement, talk through common dementia scenarios, and confirm they accept the role. Then appoint them using your jurisdiction’s recognised enduring power of attorney (medical) or equivalent. Advance Care Planning Australia centralises state/territory specifics and forms (advancecareplanning.org.au). The NIA discusses how to select and brief a healthcare proxy and why to review the choice over time (advance care planning).
If no suitable proxy exists—or where additional decisions (accommodation, services) require authority—understand the guardianship pathway in your state. Good planning avoids default tribunals later. Record who should be considered if guardianship becomes necessary and ensure your directive references legal authority clearly.
Use recognised templates or clinical forms for your state/territory. Key sections:
Healthdirect summarises what makes a directive valid and how witnessing works in each jurisdiction (https://www.healthdirect.gov.au/) Advance Care Planning Australia hosts jurisdictional forms and practical “how-to” resources (advancecareplanning.org.au).
Follow your state’s witnessing requirements (eligible witnesses, not related, etc.). If using digital signatures or digital witnessing, verify that your jurisdiction recognises these for health directives; laws vary and can change. Keep an original signed copy even if you create a fully digital workflow. The NIA stresses legality and clarity in execution (advance care planning).
A directive nobody can find is theatre. Create a distribution plan:
Work with your GP, geriatrician, or palliative team to translate preferences into a treatment plan clinicians can action (e.g., resuscitation status, hospital-transfer thresholds, community palliative referral triggers). Palliative Care Australia emphasises early integration of palliative services—symptom control, caregiver education, and psychosocial support—not just end-stage care (palliativecare.org.au).
Templates you can adapt (copy/paste, then upload)
A) Values & Preferences Summary (for the front of your directive)
B) Proxy & Access Sheet (store separately for quick action)
After completing, scan/upload to your digital legacy vault (e.g., Evaheld Vault), grant access, and send a short note to your proxy and GP.
A directive is only as good as its availability at the point of care. A vault designed for health and legacy—rather than a generic file drive—adds:
This is where tools like Evaheld Vault are purpose-built: healthcare directives and legacy artefacts live together with secure sharing, so the clinical team sees the directive while family see the person.
Is an online “living will” valid?
Yes, if it meets your jurisdiction’s legal requirements for content, signatures, and witnessing. “Online” describes the workflow and storage; the underlying legal validity still relies on your state’s rules. Start with Advance Care Planning Australia for forms and guidance, then store digitally.
Can my proxy override my directive?
Your proxy should follow your documented wishes. If a scenario isn’t covered, they use your values statement as a compass. Choose someone who will execute, not reinterpret your goals. The NIA explains this clearly in its ACP overview.
What if family disagrees with my choices?
Your directive stands (if valid). Reduce fallout with a family meeting now and transparent access later. The Alzheimer’s Association suggests involving a social worker or counsellor early in dementia planning.
Do I need a lawyer?
Often not for basic health directives—forms are provided by state authorities. Complex circumstances (multiple jurisdictions, contested guardianship, unusual refusals) warrant legal advice.
How often should I review?
Annually, and after any hospitalisation, new diagnosis, or major life event. Update the vault, notify your proxy and GP, and keep the paper copy in sync.
Dementia makes time precious and decisions complex. A good advance directive doesn’t try to script every medical twist; it captures who you are, what matters, and who speaks for you—then makes that information instantly findable when it counts. The combination of a clear directive, a brief values statement, an empowered healthcare proxy, and a secure digital legacy vault is the simplest reliable way to protect care consistency and family peace.
Before you close this tab:
That’s how you turn intention into protection—now, and in the years ahead.
Planning your will isn’t just about assets — it’s about protecting people, values, and clarity for those you love. Alongside preparing your legal documents, explore advance care planning resources to ensure your healthcare wishes are understood, and find gentle guidance for dementia support when planning for long-term wellbeing. Reflect on what truly matters through family legacy preservation resources, and digitise your legacy with a digital legacy vault that your loved ones can trust.
When the time comes to discuss your decisions, explore nurse information and care advice, and see how advance health directive tools help formalise your choices. For those seeking remembrance, discover thoughtful online tribute options, and read about great digital family legacy tools that make it easy. Begin early, act clearly, and protect your family’s future — peace of mind starts with preparation.
