What Happens If You Don’t Have Advance Directives for Dementia Care?

When a person with dementia does not complete advance directives—like a living will or durable power of attorney for health care—their family is left to make critical medical decisions without clear guidance. This often leads to confusion, guilt, and family conflict, especially during emergencies or end-of-life care. The good news is that you can start this process at any stage, and there are concrete steps to reduce stress and ensure your loved one’s wishes are honored. This article explains the risks of not having these documents and gives you a practical roadmap to get them in place.

Key points

  • Without advance directives, families may be forced to make agonizing decisions without legal authority or clear guidance from the patient.
  • Advance directives must be in writing, state-specific, and properly witnessed or notarized to be valid.
  • A durable power of attorney for health care is the most critical document—it names the person who can make decisions when the patient cannot.
  • Start the process as early as possible after a dementia diagnosis, while the person can still participate in the conversation.
  • A POLST form is a medical order that is immediately actionable by emergency responders and should be kept with the patient at all times.
  • Verbal wishes are not legally binding—only written, signed documents can guide care in a crisis.

The Legal and Emotional Vacuum

Without advance directives, no one has clear legal authority to make medical decisions for a person with dementia once they lose the ability to speak for themselves. While a spouse or adult child may have the right to stop treatments in some states, this varies widely and often requires going to court for a conservatorship—a costly, time-consuming process that adds stress during an already difficult time. The Alzheimer’s Association emphasizes that families must then make decisions based on what they believe the person would have wanted, while also acting in that person’s best interest—a balancing act that can feel impossible when you’re unsure of their preferences.

Why Written Directives Matter More Than Verbal Wishes

Many families assume that because they’ve had conversations about end-of-life care, they’re prepared. But verbal wishes are not legally actionable. According to experts, advance directives have one primary legal purpose: to name the person who will make decisions if the individual cannot. Everything else in a healthcare directive is a suggestion for care, not a binding order. The only way to create legally enforceable instructions is through state-specific forms like California’s POLST (Physician Orders for Life-Sustaining Treatment) or similar documents. Without these, doctors may be legally obligated to provide life-sustaining treatments even if the family believes the person would not want them.

The Burden on Caregivers and Family

When advance directives are missing, the weight of decision-making falls entirely on family members. They may be asked to consent to or refuse treatments like feeding tubes, ventilators, or DNR orders—decisions that can feel like choosing between life and death. One ER doctor noted that during the COVID-19 surge, many patients with severe dementia languished in hospitals because families didn’t understand what was happening and had no prior guidance. This emotional toll is compounded by the fact that many people don’t realize that a simple advance directive form only covers a few scenarios, while the actual number of decisions at end of life is far more complex.

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. Start the conversation while your loved one can still participate. Use the Dementia Values and Priorities Tool to explore what matters to them, such as: "What would make life feel worthwhile to you if you could no longer recognize family?"

  2. Download your state's official advance directive forms from a trusted source (e.g., American Bar Association, AARP, or state health department). State requirements for witnesses and notarization differ; a generic form may be invalid.

  3. Complete a durable power of attorney for health care (healthcare proxy) naming one person and a backup to make medical decisions when your loved one cannot. Ensure the person understands and accepts the role.

  4. Fill out a living will that specifies treatment preferences for end-of-life situations (e.g., feeding tube, ventilator, dialysis). Be specific: instead of "no heroic measures," state exact conditions like "if I have permanent severe brain damage, do not use a breathing machine."

  5. If your loved one is in a later stage, work with their physician to complete a POLST (Physician Orders for Life-Sustaining Treatment) form. This is a medical order immediately actionable by emergency responders.

  6. Give copies of all completed documents to the healthcare agent, primary doctor, and any care facility. Store a digital copy on a phone or cloud service for emergency access.

  7. Discuss the documents with the healthcare agent and family so everyone understands the patient's wishes. Role-play a scenario: "If Mom stops eating, what would she want us to do?" to reduce future conflict.

  8. Review and update the documents annually or after any major health change. Cross out old versions and date new ones to avoid confusion.

  9. If your loved one is already unable to make decisions and no advance directives exist, consult an elder law attorney immediately about guardianship or conservatorship to avoid default medical decisions.

What not to do

  • Don't rely on a standard will or general power of attorney. A standard will only covers property after death; a general power of attorney becomes invalid when the person loses mental capacity.

  • Don't rely solely on verbal wishes. Without written, witnessed documents, doctors are legally required to provide life-sustaining treatment in emergencies.

  • Don't wait until a crisis. If your loved one is already hospitalized or cannot communicate, it may be too late to complete advance directives. Start as soon as possible after a dementia diagnosis.

  • Don't use a form from a different state or a generic online template without checking your state's laws—it may be invalid.

  • Don't assume a living will covers a Do Not Resuscitate (DNR) order. A DNR must be signed by a physician; without it, emergency responders will attempt CPR even if the family objects.

Practical tools

  • State-Specific Advance Directive Forms (Free)

    Download your state's official forms from the American Bar Association's website or your state health department. These forms include witness and notary instructions specific to your state, ensuring legal validity.

  • Dementia Values and Priorities Tool

    Helps people with early-stage dementia clarify what matters to them (e.g., staying home, avoiding pain, being with family). Not legally binding, but essential for starting deep conversations to inform advance directives.

  • Five Wishes Document

    Legally recognized in most states, covering: who makes decisions, what medical treatment you want, how comfortable you want to be, how you want to be treated, and what you want loved ones to know. More comprehensive than a standard living will.

  • POLST (Physician Orders for Life-Sustaining Treatment) Form

    A medical order signed by a doctor that specifies whether to attempt CPR, use a ventilator, or provide artificial nutrition. Immediately actionable by emergency responders, unlike a living will. Ask the primary care physician if this is appropriate.

  • The 'Go-Bag' Document Binder

    Create a brightly colored binder with labeled sections for advance directives, medication list, provider contacts, and POLST. Keep it easily accessible and tell every caregiver where it is for quick retrieval in emergencies.

  • Alzheimer's Association 24/7 Helpline (800-272-3900)

    Free, round-the-clock support from dementia specialists who can answer questions about advance directives, care planning, and finding local legal or elder-care resources. Available in multiple languages.

Discuss with your clinician

Ask your loved one’s doctor: ‘Given their dementia stage, what medical decisions are most likely to come up in the next year? How can we prepare for those in an advance directive?’

Discuss the pros and cons of a feeding tube for someone with advanced dementia. The doctor can explain that decreased eating is normal at end of life and that tube feeding may not improve comfort or survival.

Ask about a POLST form and whether it’s appropriate for your loved one’s condition. The doctor can help you understand what each order means (e.g., DNR, DNI, comfort care only).

If your loved one has multiple chronic conditions (e.g., heart failure, COPD), ask how these interact with dementia and what treatment options align with their values.

Inquire about palliative care or hospice services. These can provide support for symptom management and help families navigate end-of-life decisions without the stress of aggressive treatments.
