If this is happening right now
If anyone near you has a drooping face, a weak arm, or speech that has suddenly gone strange, call 108 now — even if it is already improving, even if it has stopped completely. Do not drive to a clinic to check first, and do not wait for a relative to reach home. Note the exact time the symptoms began, or when the person was last seen completely normal, and give nothing by mouth: no water, no food, no tablets. The 108 network knows which centre is equipped for time-critical stroke treatment, and the clock that decides how much brain is saved — roughly four and a half hours from the first symptom — is already running. Everything else on this page is for afterwards.

What a “mini stroke” actually is
A transient ischaemic attack — TIA, what families here call a mini stroke — is the same event as a stroke, interrupted. A clot or a narrowed artery briefly starves part of the brain of blood; the brain protests in the only ways it can, and then the flow returns and the protest stops. Symptoms usually last minutes, occasionally up to an hour, and the person feels entirely normal afterwards, which is precisely the problem. The word “mini” is a translation failure, not a medical grade: nothing about the event is small. Stroke — pakkavatham, பக்கவாதம், in Tamil; pakshaghatham, പക്ഷാഘാതം, in Malayalam — is what a TIA has just rehearsed.
The most dangerous sentence in this hospital
“It went away, so we thought it was nothing.” A man tapping rubber at first light finds his right hand will not grip the knife; by the time he has walked back through the estate it grips fine, and he goes to work. A grandmother’s mouth pulls to one side while she waits for the Nagercoil bus; ten minutes later she is talking normally, and the family decide to watch her until morning. In both houses the same conclusion is drawn, and it is the wrong one. Recovery is not evidence of safety. Symptoms that resolve identify a person whose artery has already shown exactly what it is capable of, and studies show the risk of a full stroke is concentrated in the hours and days that follow — not in some distant year. The night spent watching is the very night the risk is highest.
Why 24 to 48 hours is the standard
Urgent assessment after a TIA is standard practice because the things that lower the risk of the next stroke — finding an irregular heart rhythm, treating blood pressure properly, treating cholesterol, checking the neck arteries, bringing blood sugar under control — all work best when they begin immediately. Delay does not merely postpone the benefit; it spends the window in which the benefit exists. That is why “we will go after the festival” and “let us see if it happens again” are not plans. If symptoms appeared and resolved yesterday, today is the appointment, and tomorrow is worse than today. If they appeared an hour ago, the answer is not an appointment at all — it is 108.
What the assessment actually involves
A large part of it is sitting with the person and hearing exactly what happened: which side, which function, how long, what they were doing at the time. Then blood pressure in both arms; a pulse check for an irregular rhythm, since atrial fibrillation is common, badly under-diagnosed in rural districts, and treatable once found; an ECG; blood sugar and HbA1c; cholesterol; kidney function. Imaging of the brain and the neck vessels belongs in a complete work-up and is arranged at a centre equipped for those scans. At PPK Hospital, Marthandam, the emergency department runs 24×7, a senior specialist is available the same day, and intensive care with ventilator support is in the building if the situation changes while a patient is being worked up.
Things that mimic a TIA — and why you still cannot sort it out at home
Several less dangerous conditions produce passing neurological symptoms: migraine with aura, a fall in blood sugar (below 70 mg/dL counts as low, and hypoglycemia imitates a stroke closely, especially in older people on diabetes tablets or insulin), an inner-ear vertigo attack, a faint, a seizure. Any of these might turn out to explain what happened. None of them can be established across a kitchen table or over a phone call, because they overlap with a TIA in exactly the features families use to reassure themselves: it was brief, it stopped, he seems fine now. The rule here is deliberately one-directional — assume the dangerous explanation, have it excluded properly, and be relieved afterwards. Nobody in this district has ever been harmed by going in for a suspected TIA and being told it was a migraine; the harm runs entirely the other way.
Diabetes, pressure and the vessels behind the warning
A TIA rarely arrives out of a clear sky. Behind it are usually years of quiet vascular work: blood pressure never treated to target, a cholesterol report dismissed because it said normal, tobacco, and blood sugar — sugar, as everyone here says it — running high long enough to injure vessel walls. People with diabetes carry a substantially higher risk of stroke, and long-standing nerve damage can blunt the body’s warning signals elsewhere. But this is also the useful news buried inside a frightening event: almost every factor in that list is measurable in an afternoon and most of them respond to treatment. A TIA is one of the very few warnings in medicine that arrives early enough to act on, which is the entire reason this page exists.

Treatment afterwards — and what you must not start yourself
After assessment a doctor may prescribe an antiplatelet tablet, a blood thinner if an irregular heart rhythm is found, a statin, and firmer blood-pressure control; where a neck artery is severely narrowed, a procedure may be considered. Every one of those decisions comes after the type of event is known, because treatment aimed at a clot can be dangerous where there has been a bleed. Do not start yourself on a daily aspirin. The old advice that everyone past a certain age should take one was reversed in 2019 and narrowed further in 2022, and it was never advice for an event nobody has assessed. Bring every tablet you take, in its strip, to the appointment — including anything bought at the pharmacy counter or left over from a relative’s prescription.
What families should do in the days after
Practical things carry more weight here than reassurance. Write down what was seen — the time, the side, the symptom, how long it lasted — while the memory is fresh, because the clinician will ask and second-hand versions blur within a day. Take the person to the assessment rather than sending them alone on the bus, and stay in the room for the explanation. Keep blood-pressure and sugar readings in one notebook rather than scattered across phone screens. And agree out loud, at home, what everyone will do if it happens again: that the answer is 108 and not a family discussion. In the monsoon, at night, with a long road ahead, families lose far more time to hesitation than to distance.

Frequently asked questions
Yes. Symptoms that resolve mean the blood flow returned, not that the danger passed. A transient ischaemic attack identifies an artery that has already misbehaved once, and the risk of a full stroke is highest in the first hours and days afterwards. Assessment within 24 to 48 hours is the accepted standard — waiting to see whether it happens again is not a plan.
Usually a few minutes. Most episodes settle well within an hour, and people commonly describe five or ten minutes of a weak arm, a pulled face, or speech that would not come out properly. Duration does not grade the danger: a two-minute episode and a fifty-minute episode carry exactly the same instruction, which is urgent assessment by a doctor.
The mechanism is the same — blood flow to part of the brain is interrupted. The difference is that in a TIA the flow restores itself before lasting damage is done, so the symptoms disappear completely. That is why it is best understood as a stroke that stopped early, and why it is treated as a warning rather than as an escape.
Not on your own. Aspirin, other antiplatelet tablets, blood thinners and statins may be prescribed after assessment, once a doctor knows what kind of event occurred — some strokes are caused by bleeding in the brain, where thinning the blood does harm. Routine daily aspirin for prevention was pulled back in 2019 and narrowed again in 2022. Bring your tablets and let the assessment decide.
Call 108 straight away, even if the symptoms are already fading, and note the exact time they began or when the person was last seen completely normal. Give nothing by mouth — no water, no food, no tablets. Do not drive around comparing hospitals; the ambulance network knows which centre is equipped for time-critical stroke treatment.
