Almost every other serious illness leaves you able to weigh in until near the end. Dementia is the exception — it can quietly take away the ability to decide long before anything else. A dementia directive is how you say what you’d want, at each stage, while you’re still the one who can say it.
After age 55, an American’s lifetime risk of developing dementia is about 42 percent — roughly two in five of us. It is higher still for women, for Black adults, and for those who carry the APOE ε4 gene. This is not a rare misfortune that happens to other families. It is, for most of us, a coin-flip worth preparing for.

It can take a person’s ability to make and communicate decisions long before it takes their life — often a year or more, sometimes several. That is the cruel, specific problem: by the time the hardest choices arrive, the person whose choices they are may no longer be able to make them.
An ordinary advance directive is written for a sudden event — a crash, a stroke, a moment. It answers “if something happens all at once.” Dementia isn’t a moment. It’s a slow road with very different turns, and a single yes-or-no directive can’t hold what you’d want at each of them. That’s the gap a dementia directive fills.
A dementia directive walks through the road ahead and lets you say what matters to you at each part of it — because what you’d want early on and what you’d want much later are often not the same thing.
You can live much as before, with help remembering. Many people want everything done here — treatments, medications, staying active and engaged as long as possible.
Daily life needs more support and safety. This is where people’s wishes start to differ most — and where saying yours in advance spares your family the guessing.
Many people decide that here, they want only what keeps them comfortable — not treatments that prolong things. Some feel differently. This is yours to say, now, while it’s clearly yours.
You don’t have to draft any of this alone or in legal language. Sage — a gentle companion — walks you through each stage in plain words, and you leave with a clear summary and a named proxy your family and doctors could actually use. Free, well-established templates exist too, developed at the University of Washington and at Dartmouth; the hard part was never the form. It was having the conversation in time.
A dementia directive protects you. But its quietest work is for the one who loves you and will one day have to act — the spouse or child who has to decide whether to reduce a medication, or move you to comfort care, and will carry that choice for the rest of their life.
Without your words, they’re guessing in the dark, and second-guessing forever. With them, they’re not deciding for you at all — they’re carrying out what you already told them. That is the difference between guilt and peace.
There is no alarm the day your voice stops being reliable. It slips. Which is exactly why a dementia directive has to be written before it feels necessary — while your thinking is clear and the words are unmistakably your own.
If dementia runs in your family, or you’ve had a diagnosis, this is not a document for “someday.” The whole value of it depends on doing it early. The town that made advance planning ordinary asked people one question that works just as well here: not how you want to die, but how you want to live — if things change. A dementia directive is that question, answered while you can.
A few of the moments when a dementia directive makes the most sense:
You don’t have to know the medical language or map out every stage. Sage walks you through it gently, and you leave with a clear summary and a named proxy your family and care team could actually use.
About 20 minutes. Walk through the stages, name who’d speak for you, and say what matters — in plain language. Free.
What good care looks like across a serious illness — and how a human companion, not just a document, helps a family through it.
How one town made this normal — and the “how do you want to live” reframe that made it easy for everyone.
A directive only helps if the right people can find it when it matters. The simple steps that make your choice actually work.
