What is the best WhatsApp chatbot for neurologists in Brazil?
The best WhatsApp chatbot for neurologists in Brazil is the one that answers on the number the practice already uses, with business rules written by you. An AI agent on WhatsApp for a neurologist is CertuAI's automatic assistant. It explains how to prepare for neurology tests, flags when the patient needs to come with someone, gives prices and accepted health insurance, books the appointment and tells people to call 192 (Brazil's emergency number) when the message shows stroke signs, without ever interpreting a report.

"My speech is slurred and my arm is weak": what does the AI do?
It tells the person to call 192 right away, before asking for a name, health plan or anything else. Sudden slurred speech, weakness on one side of the body, confusion, seizure, fainting, chest pain and shortness of breath are on a short list of signs that CertuAI applies on its own to every health account, without anyone writing anything.
The sentence is always this one, word for word: "This may be urgent. Call SAMU (Brazil's emergency medical service) now at 192 or go to the nearest emergency room." It takes priority over any instruction you have written, and it is one of the reasons a neurology account enters this mode on its own: the word neurology in the practice's name already makes CertuAI treat the account as health.
A strong headache is not the same thing: what does the AI answer?
An ordinary symptom question does not get the 192 sentence, and that is on purpose. For "my migraine got worse", "can I take two pills" or "is this normal after an attack", the AI says in one sentence that it doesn't evaluate symptoms or advise on treatment, and offers to book an appointment or pass the question to the team.
What changes from practice to practice is what comes next. Write in the Brain whether there is a slot for attacks, how many days it usually takes and who decides. Without that in writing, the AI offers the regular appointment, and the patient in crisis gives up halfway through the conversation.
What does the AI do with each neurology message?
| Patient message | What the AI does |
|---|---|
| "His mouth just twisted" | Tells them to call 192 or go to the emergency room, before any question |
| "Do I need to stay awake for the test?" | Repeats the preparation you wrote, with the exact hours |
| "Here is the MRI report" | Saves the image in the conversation and says it doesn't interpret tests there |
| "Can I increase my migraine medication?" | Gives no dosage advice; offers an appointment or passes the question to the team |
| "My mother forgets things, does she come alone?" | Answers with the companion rule you wrote |
| "I want to reschedule the test" | Reschedules in the CertuAI calendar or notifies the front desk, as you choose |
What CertuAI measured on clinic and practice WhatsApp
CertuAI measured when patients write on WhatsApp at 17 clinics and practices that answer with CertuAI's AI: 28.2% of messages arrived outside Monday to Friday, 8 a.m. to 6 p.m., almost 3 in 10. If the front desk works those hours, that's the part that waits until someone comes back.
| What was measured | Result |
|---|---|
| Patient messages that arrived outside Monday to Friday, 8am to 6pm | 28,2% |
| Messages that arrived on the weekend | 11,2% |
| Messages that arrived at night on a weekday, 6pm to midnight | 11,7% |
| Conversations that started outside Monday to Friday, 8am to 6pm | 29,9% |
Source: CertuAI service database, 17 clinics and practices, 19,259 patient messages on WhatsApp from Jul 30 to Sep 30, 2026, measured Oct 1, 2026. Business hours are Monday to Friday, 8am to 6pm, in each clinic's time zone. Test accounts, test contacts and imported history are excluded.
What changes in the practice with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the practice before and after the CertuAI agent.
TodayA middle-of-the-night message with stroke signs waits for business hours
With CertuAIThe person reads right away that they should call 192 or go to the emergency room
TodayTest rescheduled because the patient slept all night before the brain-wave test
With CertuAIThe preparation goes in writing at booking and comes back in the reminder the day before
TodayPatient sends a photo of the report and waits for an opinion on WhatsApp
With CertuAIThe answer is always the same: tests are not interpreted there, and an appointment is offered
TodayA migraine-attack appointment booked into a fifteen-minute follow-up slot
With CertuAIEach type of appointment has the duration you set before it goes on the calendar
What does a conversation handled by the AI look like?
Example conversation
Practice AI agent
Customer: Is a follow-up visit with tests cheaper?
AI agent: The first-visit and follow-up prices are your price. Is this the first time? Do you have a referral?
Customer: My mother is starting to lose her memory, does she need to come with someone?
AI agent: With memory loss, patients usually need to come with someone. I'll note it when booking and the reminder will repeat it.
Is an AI agent or manual customer service better for neurologists?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the practice has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Message with slurred speech and weakness on one side | Sits in the queue until someone opens their phone | Gets the instruction to call 192 right away, before any question |
| Preparation for the sleep test and the brain-wave test (EEG) | Explained over the phone and forgotten by the day before | Sent in writing, in the words you wrote |
| Photo of a report asking for an explanation | The front desk doesn't know what to answer and drops out of the conversation | Says in one sentence that it doesn't interpret tests there and offers an appointment |
| Long first visit in the wrong place on the calendar | Squeezed into a follow-up slot and the day runs late | The duration of each type of appointment is written out before booking |
| Patient who needs to come with someone | Finds out at the front door, on the day | Is told when booking and again in the reminder |
What does the WhatsApp agent do for neurologists?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Stroke signs come before everything else
Sudden slurred speech, weakness on one side of the body, confusion and fainting are on the emergency list that CertuAI applies on its own to health accounts. The person is told to call 192 before any other question.
Test prep in writing
Sleep deprivation before the brain-wave test (EEG), clean hair with no product, medication the clinic asks patients to keep or stop. Each test comes with the instructions you wrote, never a generic version.
Companion notified before the day
Patients with epilepsy, dizziness or memory loss often need to come with someone. The agent says so when booking and the reminder repeats it.
Reports and images are never interpreted
Photos of MRIs, CT scans and reports come into the conversation and stay in the history for you to see. The agent says in one sentence that it doesn't evaluate tests there and offers an appointment.
First-visit and follow-up screening
Asks whether it's the first time, whether there's a referral and whether they've brought tests, and separates first-visit slots from follow-up slots.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the practice no longer depend on you having your phone in hand.
How does the agent start answering at the practice?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for neurologists?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before you turn on the agent at the practice?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The preparation for each test the practice orders, with the hours of sleep deprivation and what to do with ongoing medication
- Which patients need to come with someone and from what age or condition
- The duration and price of the first visit, the follow-up and the visit with a test report
- The list of accepted health insurance plans, with what requires a referral and what requires authorization
- The one-sentence text for people who send a test or report asking for an opinion
- Which team member gets the alert when the conversation leaves automatic mode
Whether a patient with a new, urgent complaint can take an extra slot through the conversation or whether every extra slot goes through you first.
The most common mistake: Leaving the test preparation only in the front desk's head. Without it in writing, the agent has nothing to repeat, and the test gets rescheduled again for the same old reason. Read how to fix this.
Neurologist FAQ
Does the agent recognize stroke signs?
Sudden slurred speech, weakness on one side of the body, confusion, fainting and seizure are on the emergency list that applies on its own to health accounts. The message immediately gets the instruction to call 192 or go to the nearest emergency room.
Can it say whether a headache is a migraine?
No. On a health account, the agent doesn't evaluate symptoms, doesn't say whether something is serious and doesn't say whether it can wait. It offers an appointment or passes the question to you.
What happens when the patient sends an image of a test?
The image is saved in the conversation, for the team to see in the dashboard. The agent doesn't describe or interpret what is in the image.
Can I separate first visits from follow-ups on the calendar?
Yes. You write the duration and price of each type, and the agent asks which one it is before offering a time.
