A living will lets a person with dementia document medical treatment choices before they can no longer communicate them. Families should create it early, pair it with a health-care proxy, and share both documents with everyone involved in care. Dementia eventually may remove the ability to make even simple decisions. Early planning protects the person's voice and reduces the risk of families facing major choices during a crisis.

What a living will does—and does not do
A living will is an advance directive that states which treatments a person wants or refuses if they cannot decide or communicate. The U.S. National Library of Medicine explains that it may address CPR, tube feeding, ventilator support, medicines, tests, surgery, and blood transfusions in its guidance on living wills.
The document applies to health care. It does not manage money, distribute property, or replace a last will and testament. A useful living will connects treatment choices to the person's priorities. For example, someone might explain whether comfort, alertness, time at home, or extending life matters most when treatments offer limited benefit.
Why timing and capacity matter
A dementia diagnosis does not automatically transfer decision-making power to another person. According to the Alzheimer's Association's legal-planning guidance, the individual keeps decision-making rights while they have legal capacity, meaning the ability required by law to make the decision at hand. Planning should therefore begin while the person can understand the document and express consistent preferences.
Waiting until a hospitalization or rapid decline may leave too little time for meaningful participation. Families can start with concrete questions: The person's answers may change. Revisit the conversation after major health changes and make sure the written documents still reflect current wishes.
- Which abilities or activities make life meaningful?
- When would comfort matter more than life-prolonging treatment?
- How does the person feel about CPR, ventilation, hospitalization, surgery, or artificial feeding?
- Who understands these preferences well enough to speak for the person?
- Are there religious, cultural, or personal beliefs clinicians should know?
Why a health-care proxy is also essential
A living will cannot predict every illness, treatment, or medical tradeoff. A health-care power of attorney, sometimes called a health-care proxy, names someone to make health decisions when the person no longer can. The proxy interprets the person's values when the document does not address the exact situation. Choose someone who can understand medical information, ask questions, follow the person's wishes, and make difficult decisions under pressure.
Naming a backup is also prudent in case the first person is unavailable. The individual should discuss the documents with both people rather than relying on them to interpret unfamiliar instructions during an emergency. State law controls document requirements and generally determines who may decide when an incapacitated person has no directive. The National Institute on Aging warns that an unmarried partner may lack decision-making authority in some states without valid documents in its advance-care planning overview.
Decisions that often cause confusion
A living will is not the same as a do-not-resuscitate order. A DNR tells clinicians not to perform CPR and must be entered into the medical record by a health-care provider. Someone who does not want CPR may therefore need both written preferences and a separate medical order. Artificial feeding also deserves a specific conversation.
"No tube feeding" is not the same as "no help with eating." Families can ask how comfort-focused care, careful hand feeding, and treatment of reversible problems would work. For older adults with advanced dementia, the American Geriatrics Society says feeding tubes are not recommended. Its position statement on feeding tubes reports that careful hand feeding performs at least as well for death, aspiration pneumonia, function, and comfort, while tubes are associated with burdens such as agitation and pressure ulcers. Treatment decisions still depend on the person's stated wishes and clinical situation. Families should ask what a proposed intervention can realistically achieve, what burdens it may create, and what comfort-focused alternatives are available.
Make the plan available when it is needed
A signed document cannot guide treatment if clinicians cannot find it. Give current copies of the living will and health-care proxy to the person's physicians, hospital system, proxy, backup proxy, and care facility. Use this practical check:.
- Follow the signing and witnessing rules required by the person's state.
- Add the proxy's current phone number to every copy.
- Ask clinicians to place the documents in the medical record.
- Keep an accessible copy rather than locking away the only version.
- Send updated copies after any revision.
