Quick answer
A medical ID after a stroke does three things at once: it explains why you may not be able to speak (and that you still understand), it tells responders you are on a blood thinner, and it flags that a previous stroke makes any new weakness or confusion an emergency, not a bad day. One in three survivors has a communication difficulty, so the record has to speak when you cannot.
Stroke is common in Australia and survival is the norm. The Stroke Foundation estimates 45,785 stroke events in 2023, one every 11 minutes, and 440,481 people living in Australia with a history of stroke. Most of those people are back in the community, driving, shopping, travelling, and carrying two things a stranger cannot see: a changed ability to communicate, and a medicine list built to stop it happening again.
Aphasia: when the words will not come
According to the Stroke Foundation’s communication after stroke fact sheet, one in three stroke survivors experience difficulties with communication. Three different problems sit under that heading:
| Term | What it is | What a stranger sees |
|---|---|---|
| Aphasia | Difficulty talking, reading, writing or understanding other people when they speak | Wrong words, no words, or not following instructions |
| Dysarthria | Weakness or paralysis in the muscles used for speaking | Slurred speech, easily mistaken for drunkenness |
| Apraxia of speech | Difficulty coordinating the muscles for speech; the brain has trouble planning the movements | Effortful, inconsistent attempts at words |
The point that matters most in an emergency is the one healthdirect puts first: aphasia affects language and speech but it does not affect intelligence. A person with aphasia who cannot answer “what is your name?” may understand every word being said about them. Responders who do not know that will talk over you, decide for you, and, worst of all, may read the silence as a new stroke or a head injury.
The two emergencies a survivor is planning for
1. A second stroke
Preventing another stroke is the point of most post-stroke treatment. healthdirect notes that after an ischaemic stroke your doctor may prescribe aspirin and may also recommend other anticoagulant medicines, often called blood thinners, alongside blood pressure and cholesterol treatment. If a new stroke happens, the F.A.S.T. signs still apply, but the picture is muddier: a bystander sees a person who already has a drooped face or a weak arm and cannot tell what is new. The record has to say what your baseline is. Our guide to stroke signs and F.A.S.T. first aid covers what the bystander should do next.
2. Bleeding on a blood thinner
The same medicines that protect you from a clot make any injury bleed longer. A fall, a cut, a car accident or a knock to the head is a different event for someone on an anticoagulant, and paramedics and emergency doctors manage it differently when they know. For serious bleeding the first aid itself does not change, and we cover it in severe bleeding first aid; what changes is how quickly you need to be assessed and what the hospital does when you arrive.
Call Triple Zero (000) if a person with a history of stroke
- shows a new facial droop, arm weakness or speech change, or their existing one suddenly worsens
- becomes suddenly confused, drowsy or hard to rouse
- has hit their head or has bleeding that will not stop while taking a blood thinner
Do not wait to see whether it passes. The Stroke Foundation notes a stroke can destroy up to 1.9 million brain cells a minute.
Who reads a stroke survivor’s medical ID
Australian resuscitation guidance builds the search in. ANZCOR Guideline 2 directs rescuers, as part of the initial assessment, to check for “physical (eg. alert jewellery) or electronic alert devices (eg. smartphone application) that may be relevant to assessment or management”. For a stroke survivor the readers are:
- The bystander who finds you unable to answer. “Stroke survivor. Aphasia. I understand you.” changes their behaviour in five seconds.
- The paramedic deciding between a stroke unit, a trauma bay and a wait-and-see, who needs your baseline and your blood thinner.
- The emergency department, which needs the name of the anticoagulant and your last dose before it can plan imaging, treatment or surgery.
What to put on a medical ID after a stroke
Keep the wearable part to what a stranger needs in the first minute and let the profile carry everything else.
On the band
- STROKE SURVIVOR and the year, if space allows
- APHASIA – I UNDERSTAND YOU (or DYSARTHRIA – NOT INTOXICATED, whichever describes you)
- ON BLOOD THINNER, with the drug name if it fits
- Your membership number, so the rest can be read
In the profile
- Your baseline, in plain words: which side is weak, whether your face droops, how your speech normally sounds, whether you use a stick or a chair. This is what lets a responder tell “old” from “new”.
- How you communicate: yes/no by nodding, pointing, writing, a communication board or a phone app, and whether reading is easier than listening or the reverse.
- Every medicine by name and dose, with the anticoagulant or antiplatelet first, plus blood pressure and cholesterol drugs.
- Other conditions that often travel with stroke: atrial fibrillation, diabetes, high blood pressure, and whether you have a pacemaker or stent.
- Swallowing: whether you are on modified fluids or textures. A well-meant sip of water can be dangerous.
- Your team: GP, neurologist or stroke clinic, speech pathologist.
- Emergency contacts who can speak for you, in order, and which of them holds an enduring power of attorney or guardianship if one exists.
The Stroke Foundation and healthdirect both give the same practical tips for talking with someone who has aphasia, and they belong in your profile as an instruction to whoever finds you: speak face-to-face in a quiet place, one speaker at a time, short simple sentences, use gestures, writing or pictures, repeat the important words, and check that you have been understood before moving on.
Your baseline, your blood thinner, how you communicate — readable when you cannot say it.

For partners and carers
If you live with a stroke survivor you are usually the record. That fails the moment you are not in the room: the survivor goes out alone, or you are the one who is hurt. Write the profile together while communication is at its best, read it back to check it says what they want said, and keep it current. Our guide to setting up emergency contacts explains how to order the people who will be called, and the coming home from hospital checklist covers the first weeks after discharge, when medicines change most.
Keeping it current
Post-stroke medicine changes often in the first year and at every review after that. Update the record the day a dose changes, after any admission, and whenever your communication or mobility improves, because a baseline that describes you as worse than you now are can also mislead. If a new stroke leaves you unable to update it yourself, a trusted contact with access should do it before you leave hospital.
FAQs
What should a medical ID say after a stroke?
On the band: “stroke survivor”, your communication difficulty in words a stranger understands (for example “aphasia – I understand you”), “on blood thinner” and a number that opens your record. In the record: your baseline weakness and speech, how you communicate, every medicine with the anticoagulant first, related conditions, swallowing restrictions, your stroke team and your emergency contacts.
How many stroke survivors have trouble communicating?
The Stroke Foundation states that one in three stroke survivors experience difficulties with communication. That includes aphasia (language), dysarthria (weak speech muscles) and apraxia of speech (coordinating speech movements). Australia had an estimated 440,481 people living with a history of stroke in 2023.
Does aphasia mean the person cannot understand me?
No. healthdirect is explicit that aphasia affects language and speech but does not affect intelligence. Many people with aphasia understand far more than they can say. Speak to them directly, face-to-face, in short sentences, one speaker at a time, and use gestures, writing or pictures, then check you have understood each other.
Why should a blood thinner be on a stroke survivor’s medical ID?
Because it changes how any injury is handled. Anticoagulant and antiplatelet medicines prescribed after an ischaemic stroke make bleeding harder to control, so a head knock or a wound that would be minor for someone else needs faster assessment, and hospital staff need the drug name and last dose before imaging, treatment or surgery.
How can a bystander tell a new stroke from an old one?
Often they cannot, which is why your record should describe your baseline: which side is weak, whether your face droops, how your speech usually sounds. Anything new or suddenly worse is treated as a stroke: call Triple Zero (000) straight away. The Stroke Foundation notes a stroke can destroy up to 1.9 million brain cells a minute, so waiting to see is not an option.
Do paramedics look for medical IDs?
Yes. The Australian and New Zealand resuscitation guidelines include checking for physical alert jewellery or electronic alert devices in the initial assessment of an emergency. A band is found fastest; the number on it should open the detail a paramedic or emergency doctor needs.
How often should a stroke survivor update their medical record?
The day any medicine or dose changes, after every hospital admission, at every specialist review, and whenever communication or mobility changes in either direction. Medicine changes are most frequent in the first year after a stroke.
