Parkinson’s progresses slowly, which means that even if your judgment is completely clear today, it is worth thinking now about a future in which making decisions is harder. Two pieces of paperwork do most of the work here, and sorting them out early removes a great deal of confusion and conflict from a family later on.
Choosing your own decision-maker, instead of having one chosen for you
A durable power of attorneyA legal document you complete while you still have decision-making capacity, naming someone you choose to make decisions on your behalf if you later cannot. It is usually distinguished from arrangements made after capacity is lost, where a court appoints a guardian or conservator.Learn more is something you sign while you still have capacity, naming a person you choose to act for you if you later cannot. That is the whole point of it: you pick, in advance, rather than leaving it to be decided about you.
There are normally two separate documents, and you want both:
- A healthcare power of attorney — also called a healthcare proxy or medical power of attorney — authorizing someone to make medical decisions for you, including decisions about life-extending treatment, if you are unable to make them yourself.
- A durable financial power of attorney, naming someone to handle your finances, taxes and legal matters. It does not have to be a lawyer.
The alternative is what happens if you don’t. Without a financial power of attorney in place, the Parkinson’s Foundation notes, you may end up subject to a court-ordered guardianship or conservatorship — costly, slow, and decided by a court rather than by you.
The details vary by jurisdiction more than people expect. Whether a “springing” power of attorney (one that takes effect only on incapacity) is recognized differs by state, and so does how incapacity itself is defined — which is genuinely hard to pin down. Witnessing and notarization requirements differ too. This is not a form to guess at.
You can also set out what treatment you would want
An advance directiveA document recording, in advance, what medical treatment you would or would not want at the end of life — particularly treatments that would prolong life without a realistic prospect of recovery. It is completed by you while you are able to make the decision, and can be changed or withdrawn at any time.Learn more records, in advance, what medical treatment you would and would not want near the end of life — above all, treatments that would prolong life without a realistic prospect of recovery. The document that speaks to this specifically is often called a living will: it sets out your wishes about life-prolonging care when death is imminent from a terminal illness. Living wills are recognized in most, though not all, states.
Two things to keep clear. First, this is different from orders written by a physician for someone already in the final stage of an illness, such as a POLST or a DNR order — those differ in who writes them and when. Second, you complete it yourself while you are able to make the decision, and you can change or withdraw it at any time. It is not a one-way door.
What happens if you don’t prepare
If capacity declines significantly with nothing in place, you can end up in a situation where no family member has the legal authority to do your banking or consent to your medical treatment. The route out of that is a court application for guardianship — and the time and procedure involved feel heaviest precisely when the situation is urgent. A will, and depending on your circumstances a revocable living trust naming a successor trustee, belong in the same conversation for the same reason.
When to do it
The Parkinson’s Foundation is direct about this: it is extremely important to have these documents in place as soon as possible after a diagnosis. Preparing early also creates a record of your wishes over time, which is worth something in itself.
The window narrows. An attorney may ask for a letter from your neurologist about the cognitive effects of Parkinson’s on you and the medications you take, in order to document capacity at the time of signing. If cognitive decline has already progressed, a power of attorney may no longer be possible at all — and guardianship becomes the only remaining route. That asymmetry is the whole argument for doing it while there is no urgency.
Tell your family what you have decided
Preparing the documents is only half of it. If your wishes exist only on paper, there is a real chance that when the moment comes, your family don’t know the paperwork exists, or read it differently from each other, and the conflict you were trying to prevent happens anyway. Pick an unhurried moment, explain why you are doing this and roughly what it says, and make sure the person you named knows they have been named. Give copies to the people who would need them.
Where to get help
An elder law or estate planning attorney is the right professional for this — the National Academy of Elder Law Attorneys (naela.org) maintains a directory. A social worker at your clinic or hospital can tell you which forms your jurisdiction uses and how they need to be witnessed. In the United States, the Parkinson’s Foundation Helpline (1-800-4PD-INFO, 1-800-473-4636) can point you toward local resources.
What you can do now
Rather than deciding anything today, start by learning what these two documents are and raising the subject with your family once. That conversation is usually the hardest part, and everything else follows from it.
