Indiana Advance Directive for Dementia: Timing, Capacity, and Guardianship

The window for completing an advance directive closes when cognitive capacity disappears. For families dealing with Alzheimer's disease or other forms of dementia, this creates an urgent timeline — and the most common mistake is waiting too long.

Once an Indiana resident loses decisional capacity, they can no longer legally execute an advance directive. At that point, the family's only option is guardianship through the courts, which is slower, more expensive, and more invasive than an advance directive could ever be.

The Capacity Requirement

To execute a valid advance directive in Indiana, you must be an adult with "decisional capacity" — the ability to understand the nature and consequences of the healthcare decisions you are documenting. This is not the same as a dementia diagnosis.

A person with early-stage Alzheimer's or mild cognitive impairment may still have sufficient capacity to execute an advance directive. Capacity is assessed at the moment of signing, not based on a general diagnosis. Someone who has lucid periods, understands what an advance directive does, and can communicate their treatment preferences may still legally sign.

The practical challenge: capacity diminishes progressively and unpredictably. What is possible today may not be possible in three months. This is why every geriatrician, elder law attorney, and hospice worker will tell you the same thing — do not wait.

When to Sign

The ideal time to sign an advance directive is before any cognitive decline begins. For families already facing a dementia diagnosis, the answer is: as soon as possible, during a period of clear capacity.

Key timing considerations:

• At diagnosis. An early Alzheimer's or dementia diagnosis is the clearest signal to act immediately. The person likely still has capacity to make and communicate their wishes.
• Before facility admission. Nursing homes and assisted living facilities in Indiana will ask about advance directives during intake. Having one already executed avoids last-minute pressure.
• Before a lucid period passes. If your parent or spouse has fluctuating capacity, work with their physician to identify a window when capacity is clear, and execute the directive during that window.

If there is any question about capacity, ask the treating physician to provide a written assessment of capacity at the time of signing. This documentation makes the directive significantly harder to challenge later.

What to Include for Dementia-Specific Planning

Standard advance directives cover terminal conditions and imminent death. But dementia presents a different scenario — the person may live for years with progressive cognitive decline. Your directive should address:

• Treatment preferences at each stage. What interventions are acceptable during mild impairment? Moderate? Severe? The answer may change as the disease progresses.
• Artificial nutrition and hydration. Many patients with advanced dementia lose the ability to eat independently. Your directive should specify whether you want a feeding tube or prefer comfort feeding only.
• Hospitalization threshold. At what point should infections, falls, or other complications be treated aggressively versus managed with comfort measures?
• Psychiatric advance directive. Indiana allows a separate psychiatric advance directive specifying preferences for psychotropic medications and restraint. This is relevant for dementia patients who may experience agitation or behavioral symptoms requiring psychiatric intervention.

Advance Directive vs. Guardianship

If capacity is already gone, an advance directive is no longer an option. The family must petition the court for guardianship — a formal legal proceeding where a judge appoints someone to make decisions on the incapacitated person's behalf.

Guardianship in Indiana requires:

• Filing a petition in the county where the person resides
• A court hearing where incapacity is established by medical evidence
• Ongoing court oversight of the guardian's decisions
• Filing fees starting at $177, plus attorney fees often ranging from $2,000 to $5,000

Compared to an advance directive that costs nothing to execute and gives the appointed HCR broad authority without court involvement, guardianship is a last resort. An advance directive executed while capacity exists prevents the need for guardianship entirely.

There is no middle ground. You either execute the directive while the person can still sign, or you go through the courts after they cannot.

For Adult Children Managing a Parent's Care

If you are the adult child helping a parent with early cognitive decline, the advance directive conversation needs to happen now — not after the next hospital visit, not after the next family gathering, now.

Bring it up in practical terms: "Mom, I want to make sure your doctors know exactly what you want if you can't tell them yourself." Have the conversation while it is still a planning exercise rather than an emergency response.

The Indiana Advance Directive & Living Will Kit includes dementia-specific treatment preference sections and a capacity documentation guide to help families act during the window when legal execution is still possible.
