Colorado Advance Directive for Dementia: Planning While There Is Still Time

A dementia diagnosis creates a closing window. Colorado law requires that anyone signing an advance directive must be "of sound mind" at the time of execution — once cognitive decline advances past a certain point, the person can no longer legally create or modify these documents. The family is then left without a healthcare agent, without documented treatment preferences, and facing the prospect of a guardianship petition in probate court.

Early-stage dementia is the last opportunity to get these documents in place. Waiting even six months too long can mean the difference between your parent's wishes being honored and a judge appointing a stranger to make their medical decisions.

Why Dementia Makes Advance Directives Urgent

Three things happen simultaneously with cognitive decline:

Decision-making complexity increases. Dementia patients face a growing cascade of medical decisions — medication management, behavioral interventions, mobility restrictions, potential facility transfers — and these decisions accelerate as the condition progresses.

The ability to make those decisions decreases. The disease progressively erodes judgment, communication, and the capacity to understand medical options. There comes a point where a person can no longer meaningfully consent to or refuse treatment.

Without an MDPOA, no one has clear authority. Colorado does not automatically grant a spouse or adult child the right to make medical decisions. Under the Proxy Decision-Maker Act (C.R.S. § 15-18.5-103), all "interested persons" must reach unanimous consensus. For families with multiple adult children — especially blended families or estranged siblings — this requirement frequently leads to court-ordered guardianship proceedings.

Capacity Issues During Signing

Colorado does not require a formal capacity evaluation to execute advance directives. The legal standard is "of sound mind," which means the person understands what they are signing, why they are signing it, and the consequences of their decisions.

For someone with early-stage or mild dementia, this standard is almost always met. They can describe their treatment preferences, name the person they trust to make decisions, and articulate their values around quality of life. The diagnosis itself does not disqualify them.

However, if there is any concern about capacity being challenged later — particularly by a family member who disagrees with the decisions made — take these protective steps:

• Have the signing witnessed by a physician who can document the person's capacity at the time of execution
• Use notarization instead of or in addition to witnesses
• Complete the documents during a "good day" when the person is alert and oriented
• Consider a brief video recording of the person explaining their choices (not as a legal requirement, but as evidence of understanding)

What to Address in the Dementia-Specific Directive

Standard advance directive templates cover ventilators, feeding tubes, and life support for terminal conditions. But dementia creates scenarios those templates do not anticipate:

Medication management. Should the healthcare agent consent to antipsychotic medications for behavioral symptoms? What about sedatives for agitation?

Facility decisions. At what point should the person move from home to assisted living to a memory care unit? Who makes that call?

Feeding and nutrition. Late-stage dementia often involves difficulty swallowing. The living will's artificial nutrition section becomes directly relevant, but the person should also address hand-feeding preferences and comfort feeding.

Restraints and supervision. Should the care team use physical or chemical restraints if the person is at risk of wandering or falling? This is a values-driven decision that varies widely among families.

Research participation. Would the person want to participate in clinical trials for dementia treatments, even if they can no longer consent? The MDPOA agent can make this decision if the directive grants that authority.

The Living Will vs. Ongoing Care

For a dementia patient, the MDPOA is the more critical document. The living will only activates when two physicians certify a terminal condition or persistent vegetative state — it does not cover the years of progressive decline that precede that point. During those years, the MDPOA agent makes every medical decision.

That said, the living will still matters for the end stage, when the question of ventilators, feeding tubes, and life support becomes real. Both documents should be in place.

Act Before the Window Closes

The Colorado Advance Directive & Living Will Kit includes guidance specific to progressive conditions, an agent briefing worksheet so the person your parent trusts knows exactly what they expect, and a treatment preferences worksheet that goes beyond the standard terminal-illness scenarios to cover the decisions dementia families actually face.
