🩺 Introduction:
A Whisper Before the Storm
You’re having a cup of tea when suddenly, your arm feels numb, or you notice a slight droop on one side of your face. You might even stumble over your words for a moment.
It’s easy to dismiss these signs.
But what if they’re not just random or fatigue-related?
What if they are the body’s final warning before a full-blown stroke?
These could be symptoms of a Transient Ischaemic Attack (TIA) — often called a micro-stroke — and they require urgent medical attention.

⚠️ What is a Micro-Stroke?
A micro-stroke occurs when there's a temporary blockage of blood flow to the brain. Unlike a major stroke, which causes permanent damage, the symptoms of a TIA usually last from a few minutes to a few hours and then disappear completely.
But make no mistake:
A TIA is a major red flag. It’s often a precursor to a larger stroke and should never be ignored.
🧠 Think of a micro-stroke as the brain's fire alarm — don’t wait for the fire!
🔍 Symptoms of a Micro-Stroke
The symptoms can be subtle and short-lived, but they are very similar to those of a full stroke. Watch out for:
1. 😶🌫️ Face Drooping
One side of the face may feel numb or appear to droop.
Ask the person to smile — if it's uneven, it's a red flag.
2. ✋ Arm Weakness or Numbness
Sudden loss of strength or numbness in one arm or leg, especially on one side.
Ask the person to raise both arms — if one drifts downward, it's a sign.
3. 🗣️ Speech Difficulties
Slurred or garbled speech.
Inability to repeat simple phrases.
4. 🌫️ Sudden Confusion or Disorientation
Inability to understand what others are saying.
Temporary memory lapses.
5. 👁️ Vision Problems
Sudden blurred or double vision.
Temporary blindness in one eye.
6. 🌀 Loss of Balance or Dizziness
Trouble walking or coordinating movement.
Feeling faint or like the room is spinning.
⏱️ Time is Brain: Act FAST!
Health organisations around the world recommend the FAST acronym to identify stroke or TIA symptoms:
F – Face: Ask them to smile. Does one side droop?
A – Arms: Can they lift both arms? Does one drift down?
S – Speech: Is their speech slurred or strange?
T – Time: If you observe any of these signs, call emergency services immediately. ⏰🚑
Even if the symptoms vanish, you should still seek urgent medical help — TIAs are warning signs.
🧬 What Causes a Micro-Stroke?
🩸 1. Blood Clots
Most TIAs are caused by tiny blood clots temporarily blocking blood vessels in the brain.
🧱 2. Atherosclerosis
A build-up of fatty deposits in the arteries can narrow blood vessels, limiting oxygen to the brain.
❤️ 3. Heart Conditions
Conditions like atrial fibrillation, heart valve disease, or heart failure can contribute to blood clots.
💉 4. High Blood Pressure
Uncontrolled hypertension can weaken arteries and increase stroke risk.
🚬 5. Lifestyle Choices
Smoking, heavy alcohol intake, poor diet, and lack of exercise significantly raise your TIA risk.
🏥 Diagnosis & Medical Tests
If a TIA is suspected, doctors may perform:
CT or MRI scan to check for brain abnormalities.
Carotid ultrasound to assess blood flow in neck arteries.
Echocardiogram to check for heart issues.
Blood tests for cholesterol, sugar, and clotting factors.
Even if symptoms fade, these tests are crucial to prevent future strokes.
💊 Treatment: Prevention is Power
Though micro-strokes don’t leave permanent damage, they require aggressive treatment to avoid a major stroke.
Prescribed treatments may include:
Antiplatelet drugs like aspirin or clopidogrel.
Blood pressure medications.
Statins to lower cholesterol.
Lifestyle changes: Quitting smoking, eating healthy, and regular exercise.
Surgery, in rare cases, to clear blockages in arteries (carotid endarterectomy).
🛡️ Prevention Tips: Stop a Stroke Before It Starts
✅ 1. Monitor Your Blood Pressure
Regularly check your BP — aim for under 120/80 mmHg.
✅ 2. Manage Diabetes & Cholesterol
Follow prescribed treatments and get routine check-ups.
✅ 3. Eat Heart-Healthy Foods
Focus on fruits, vegetables, nuts, lean proteins, and whole grains. Cut down salt and sugar.
✅ 4. Exercise Regularly
Even 30 minutes of walking five days a week can greatly reduce stroke risk.
✅ 5. Avoid Smoking & Excess Alcohol
These are leading lifestyle-related causes of stroke and TIA.
✅ 6. Listen to Your Body
If something feels off — even briefly — don’t ignore it.
🧘 Recovery & Mental Health After a TIA
While physical damage may not be evident, many people experience anxiety, depression, or fear after a micro-stroke.
It’s essential to:
Talk to a counsellor or therapist.
Join a stroke support group.
Stay engaged with your doctor for follow-up care.
🧾 Final Thoughts: Don't Wait for a Bigger Alarm
A micro-stroke is not “minor.”
It’s the brain’s cry for help, a preview of what’s to come if changes aren't made immediately.
By learning to spot the early signs, acting quickly, and making smart lifestyle changes, you can prevent a major stroke — and potentially save a life.
💡 If your face feels strange, or your arm won't rise, don’t think twice — call for help! 🚨
