What the device can and cannot do for your diagnosis
Deep brain stimulation uses implanted electrodes and a pulse generator. In Parkinson's disease it may help selected symptoms, but it does not cure the disease. That single sentence carries most of the consent weight, because it defines what you are agreeing to: symptom management through a device, not a cure and not a replacement for every other part of your care.
The first consent question is therefore diagnostic, not technical. Ask the team to state, in writing, which diagnosis they are treating, which specific symptoms they expect the stimulation to improve, and which symptoms they do not expect it to change. A team that cannot separate those two lists has not yet given you a plan you can consent to.
This matters because the same device is used across different conditions and different symptom targets. If your expectation is broader than the team's stated target, you may agree to a procedure that meets their criteria and still disappoints you. Ask them to describe what a good result would look like for you specifically, and what would count as an unsatisfactory result.
You should also ask what alternatives were considered and why they were set aside. That is not a challenge to the team's judgement; it is the ordinary content of informed consent. If the answer is that other options were not discussed, that is itself information you need before agreeing.
Which device, and who decides the settings
Deep brain stimulation is not one product. Ask the team to name the specific device and generator they propose, and to explain why that system was chosen for you. Then ask the question that patients often forget: who will program it, where, and under what arrangement.
Programming is not a one-off event at the end of surgery. Settings are adjusted over time, and those adjustments require a clinician with the right equipment and experience. Before you consent, you need a clear answer to whether programming can be done in your home country, by whom, and what happens if it cannot.
Ask the team to put the programming plan in writing: who performs the initial programming, how follow-up adjustments are arranged, what the patient or family is expected to do between visits, and what the team's own limits are. If the answer depends on a device company representative or a specific clinic, name that dependency explicitly.
A related consent question is what happens if the device or a component fails, needs replacement, or must be removed. Ask who would manage that, where, and whether the original team would be involved. You are not asking for a guarantee; you are asking who holds responsibility for each scenario.
Suitability is the hospital's decision, not a booking step
An enquiry, a records review or a preliminary reply is not a suitability decision. The hospital decides whether deep brain stimulation is appropriate for you, and that decision may only be final after in-person assessment. Treat any earlier communication as provisional.
Ask the team to explain what still has to be confirmed before they would consider the procedure appropriate. Common items include the diagnosis itself, the response to existing treatment, imaging, cognitive and psychiatric assessment, and the patient's own goals. Ask which of these they have already reviewed and which remain open.
This is where a preliminary reply can mislead. A message that says your case 'looks suitable for review' is not the same as a decision that you are a candidate. If you are unsure which one you have received, ask directly: is this a provisional review, or a clinical decision that the procedure is appropriate?
You should also ask what would make the team decide against the procedure. A team that can describe its own exclusion criteria is giving you a more honest picture than one that only describes benefits.
What the written plan and quote actually cover
Ask for a written plan that separates the hospital's medical charges from any coordination or interpretation fees you have agreed. These are different payees and different documents. Do not accept a single figure described as all-inclusive without seeing what it includes.
For the hospital side, ask what the quote covers: the assessment, the device and implantation, hospital stay, programming sessions, follow-up visits and any expected replacement or revision. Then ask what is explicitly excluded, and what is still undecided. If a component's cost depends on a choice not yet made, ask when that choice is made and who makes it.
For any coordination service, ask what the fee covers, who receives it, and what happens if the plan changes. Coordination fees and hospital medical fees are separate, and no credit, deduction or offset against later hospital charges is available. Ask the provider to confirm this in its written quote.
Finally, ask how the quote would change if the team's assessment changes the plan. A quote is only useful if you know which parts are fixed and which are estimates pending confirmation.
Continuing care after you travel home
The part of overseas device care that can be left unresolved is not the surgery; it is what happens afterwards. Before consenting, ask the team to describe how continuing specialist care would work once you leave China. Ask who would manage programming, troubleshooting and any future replacement, and whether that person has already been identified.
If the answer is that your home clinician would take over, ask whether that clinician has been contacted and has agreed. A plan that assumes someone at home will accept responsibility, without confirming it, is not yet a plan. You can ask the team what information they would send, and in what form.
Ask what the team would need from your home clinician, and what your home clinician would need from the team. Device details, settings, imaging and operative notes are typical items, but confirm the actual list with both sides rather than assuming a standard package.
You should also ask what you are expected to do if a problem arises before a home clinician is in place. Ask for a named contact and a described route, and ask what the team can and cannot do remotely. Do not assume remote programming is possible; ask whether it is, for this device and this team.
How to get clear answers before you agree
Put your questions in writing and ask for written answers. A short list is easier for a busy team to answer than a long conversation, and it gives you something to compare against later. Ask for the answers in English, or arrange interpretation you trust.
If you are working with a coordination service, its role is to help you request records, arrange interpretation and put questions to the hospital. It does not decide suitability, prescribe, dispense or promise availability. You can start with a brief summary of your situation; a full medical archive is not needed for a first enquiry, and an initial enquiry does not require buying a proxy consultation.
Before you sign anything, check that you can restate the plan in your own words: the diagnosis, the target symptoms, the device, the programming arrangement, the costs and the follow-up route. If any of those is still unclear, that is the item to resolve next, not a detail to settle after surgery.
A practical next step is to write your four or five remaining questions and send them to the hospital team, with a copy to anyone coordinating your care. Ask for answers in writing before you agree to a date.
