A Mini-Stroke Is an Emergency, Not a Reprieve: Why Malaysia Should Act the Same Day
October 29 is World Stroke Day. Ahead of it, CodeBlue has published my opinion piece on the transient ischaemic attack: the mini-stroke whose symptoms pass, and which is too easily put down to tiredness or the heat. CodeBlue is the health news site of the Galen Centre for Health and Social Policy in Malaysia. This post sets out the argument for readers in Malaysia and Singapore, and for families deciding what to do after an episode that seemed to go away.
How common is stroke in Malaysia?
Stroke was Malaysia’s third leading cause of death in 2023, and the Galen Centre estimates about 52,000 new strokes a year, roughly 140 every day. Neurologists interviewed by CodeBlue have noted that around one in four strokes now occurs in people under 50. Much of the discussion around stroke care, quite rightly, concerns what happens once a stroke has occurred: reaching a hospital that can dissolve or remove the clot, and the rehabilitation that follows. My article is about an earlier point, one that is less costly to act on and easily overlooked.
What is a mini-stroke?
A transient ischaemic attack, or TIA, is a brief interruption of blood supply to part of the brain. For a few minutes, sometimes up to an hour, there may be drooping of one side of the face, weakness in an arm, slurred speech or loss of vision in one eye. Then the symptoms resolve. A TIA indicates that a clot has reached the brain and cleared before causing lasting damage, and the risk of a stroke is highest in the days that follow. I explain this in a short video on TIA and carotid artery disease.
Why does acting on the same day matter?
In an international registry of nearly 4,800 patients, most of whom were assessed by a stroke specialist within 24 hours, about one in twenty went on to have a stroke within a year. In the EXPRESS study from Oxford University, when assessment and treatment started on the same day rather than at a later clinic appointment, the 90-day risk of stroke fell from about 10 per cent to about 2 per cent. The treatments themselves were well established: antiplatelet medication, a statin, blood pressure control and timely investigation. What changed was when they began.
Where do the carotid arteries come in?
The two carotid arteries in the neck supply much of the blood to the brain. Like the arteries of the heart and legs, they can narrow with cholesterol plaque, and a fragment of plaque can travel to the brain. About one in 12 ischaemic strokes has been attributed to narrowing of this kind. It can be identified with an ultrasound scan of the neck, a painless test that takes about 20 minutes and needs no injection.
Where the narrowing is significant and has caused symptoms, surgery to clear the artery, or in selected patients a stent, reduces the risk of a further stroke. Timing matters here too: in a pooled analysis of the major trials, the benefit was greatest when surgery took place within two weeks of symptoms. The condition is explained on the carotid artery disease page, and the two treatments on the carotid surgery and stenting page.
“The mini-stroke offers a valuable opportunity: a warning that arrives before lasting harm, with a window of days in which established treatment can lower the risk of what may follow.”
What did I suggest for Malaysia?
Three things appear to make the greatest difference after a mini-stroke, in Malaysia as elsewhere.
- Prompt assessment. In a number of health systems, rapid-access TIA clinics or emergency department protocols allow treatment to begin, and a carotid scan to be arranged, within a day or two. This does not require a specialist stroke centre; it depends mainly on an agreed pathway and on scan capacity being available when needed.
- Recognising symptoms that resolve. The FAST message (Face, Arms, Speech, Time) is widely known. It applies even when the symptoms have settled by the time help is sought.
- Knowing one’s blood pressure. The National Health and Morbidity Survey 2023 estimated about 6.7 million Malaysian adults with hypertension, and 11.9 per cent of all adults had raised blood pressure that had not previously been diagnosed. A blood pressure check is a simple place to start.
What should you do if it happens?
If stroke symptoms are happening now, call 999 in Malaysia or 995 in Singapore. If they have already passed, do not wait to see whether they come back: a same-day medical assessment remains the safest course, even if you feel entirely well. I made the same point for readers in Singapore in a letter to The Straits Times Forum this week.

Preparing for a vascular review
If you have been told after a mini-stroke that a carotid artery is narrowed, or would like a second opinion on a carotid scan, bring the scan report and images, a list of your medicines and your recent blood test results. Patients travelling from Malaysia and elsewhere in the region will find practical details on the international patients page, and can reach the clinic through the contact page.
