Stroke: Recognise FAST Signs and Save a Life
A stroke happens when blood flow to a part of your brain is suddenly cut off β either by a clot or a burst blood vessel β and brain cells begin to die within minutes. Recognising the warning signs using the FAST test and calling emergency services immediately can mean the difference between full recovery and permanent disability. In India, stroke affects an estimated 1.8 million people every year (ICMR National Stroke Registry, 2022), and the numbers are rising, particularly among younger adults.
What Is a Stroke?
A stroke is a medical emergency in which the brainβs blood supply is interrupted. Without oxygen-rich blood, brain cells start dying at a rate of roughly 1.9 million neurons per minute (American Heart Association, 2026). The longer treatment is delayed, the greater the damage.
There are three main types:
-
Ischaemic stroke (caused by a blood clot blocking a brain artery) β accounts for approximately 85% of all strokes (Mayo Clinic, 2025). A clot may form in the brainβs own blood vessels (thrombotic stroke) or travel from elsewhere in the body, often the heart (embolic stroke).
-
Haemorrhagic stroke (caused by a blood vessel in the brain leaking or rupturing) β often linked to uncontrolled high blood pressure. This type requires emergency treatment to control bleeding and reduce pressure on the brain.
-
Transient ischaemic attack (TIA), sometimes called a βmini strokeβ β produces stroke-like symptoms that resolve within minutes to hours. A TIA is a serious warning: approximately 10β15% of TIA patients go on to have a full stroke within 90 days (NHS, 2025). Never ignore it.
Understanding which type has occurred guides the treatment your medical team will use β and speed is everything.
Recognising a Stroke: The FAST Test
The FAST test is the most reliable way for anyone β not just doctors β to spot a stroke in progress. The American Heart Association and the American Stroke Association re-emphasised FAST in their updated 2026 clinical guidelines because it saves lives.
Here is what each letter stands for:
-
F β Face drooping. Ask the person to smile. Does one side of the face droop or look uneven? Is it numb?
-
A β Arm weakness. Ask them to raise both arms. Does one arm drift downward? Can they keep it up?
-
S β Speech difficulty. Ask them to repeat a simple phrase like βThe sky is blue.β Is their speech slurred, garbled, or hard to understand?
-
T β Time to call emergency services. If you observe any one of these signs β even if the symptoms seem to come and go β call your local emergency number immediately. Note the exact time symptoms started, because this information directly affects treatment options.
Beyond FAST: Other Warning Signs
Not every stroke presents with the classic three signs. Watch for these additional symptoms, all of which appear suddenly:
-
Severe headache with no known cause β often described as βthe worst headache of my lifeβ
-
Loss of vision in one or both eyes
-
Confusion or difficulty understanding what others are saying
-
Loss of balance, coordination, or difficulty walking
-
Dizziness that is sudden and unexplained
If any of these appear without warning, treat it as a potential stroke.
What to Do During a Stroke Emergency
Knowing what to do in the critical first minutes can protect the brain until medical help arrives. Follow these steps:
-
Call emergency services immediately. Do not attempt to drive the person to the hospital yourself. Paramedics can begin assessment and treatment en route.
-
Note the time. Write down or remember exactly when symptoms started. Many stroke treatments β including clot-dissolving medication (tPA) β are most effective within a specific time window (up to 4.5 hours for tPA, per AHA 2026 guidelines).
-
Keep the person safe. Lay them down with the head slightly elevated. Loosen tight clothing around the neck.
-
Do not give food, water, or medication. Stroke can impair swallowing, creating a choking risk. Do not give aspirin β the type of stroke (clot vs.Β bleed) determines the right treatment, and aspirin can worsen a haemorrhagic stroke.
-
If they vomit, gently turn them onto their side to prevent choking.
-
Stay with them. Offer calm reassurance. Monitor breathing until the ambulance arrives.
The phrase doctors use is βtime is brain.β Every minute of delay costs roughly 1.9 million neurons. Acting quickly is the single most important thing you can do.
Risk Factors: Who Is at Greater Risk?
Stroke can happen to anyone. However, certain factors increase your risk significantly. The ICMR National Stroke Registry Programme (2020β2022) found that hypertension was present in 74.5% of all stroke patients in India β making it the leading modifiable risk factor across every age group.
Modifiable risk factors (factors you can control or treat):
-
High blood pressure (hypertension) β the single most important risk factor
-
Diabetes mellitus β doubles stroke risk
-
High cholesterol β contributes to artery-narrowing plaque buildup
-
Smoking β doubles stroke risk; quitting substantially reduces it within 2β5 years
-
Obesity and physical inactivity
-
Excessive alcohol consumption
-
Atrial fibrillation (an irregular heart rhythm) β causes blood clots that can travel to the brain
-
Obstructive sleep apnoea
Non-modifiable risk factors (factors you cannot change):
-
Age β risk increases after 55
-
Family history of stroke or heart attack
-
Prior stroke or TIA β the strongest predictor of future stroke
-
Gender β men have a slightly higher lifetime risk, though women account for more stroke deaths
A concerning trend: the ICMR registry found that nearly 14% of stroke patients in India are under 45 years old (ICMR, 2022). Stroke is no longer a condition that only affects the elderly. If you have two or more risk factors, speak with a neurologist about a personalised prevention plan.
Treatment: What Happens at the Hospital
Once you reach the hospital, the medical team works against the clock. Here is what stroke treatment typically involves:
For ischaemic stroke (blood clot):
-
Thrombolysis (tPA / tenecteplase) β a clot-dissolving drug administered intravenously. Most effective within 4.5 hours of symptom onset. The AHAβs 2026 guidelines added stronger evidence supporting tenecteplase as an alternative to traditional tPA.
-
Mechanical thrombectomy β a catheter is guided through the artery to physically extract the clot. Can be performed up to 24 hours after symptom onset in selected patients with large vessel blockages.
For haemorrhagic stroke (bleeding):
-
Emergency medication to reduce blood pressure and control bleeding
-
Surgery to relieve pressure on the brain, if the bleed is severe
After stabilisation:
-
Stroke Intensive Care Unit monitoring to prevent complications
-
Immediate initiation of secondary prevention medications (blood pressure control, antiplatelet or anticoagulant therapy, statins)
-
Neuro-rehabilitation β at Neuro Panacea Hospitals, our rehabilitation team (physiotherapists, speech therapists, occupational therapists) begins working with the patient within 24 hours of stabilisation. Our neurologists, including fellowship-trained stroke specialists, use neuro-navigation technology for precision in surgical cases and maintain a door-to-needle target under 30 minutes for thrombolysis.
If you or a family member has experienced a stroke, ask our team about the stroke rehabilitation programme and ongoing secondary prevention at our neurosciences centre.
Prevention: Reducing Your Stroke Risk
Up to 80% of strokes are preventable through lifestyle changes and medical management (WHO, 2024). Here are evidence-based steps you can take today:
-
Control blood pressure. Get it checked regularly. If you are diagnosed with hypertension, take your prescribed medication consistently β do not skip doses.
-
Manage blood sugar. Uncontrolled diabetes accelerates damage to blood vessels.
-
Quit smoking. Your stroke risk begins to drop within weeks of quitting and reduces substantially within 2β5 years.
-
Stay physically active. The AHA recommends at least 150 minutes of moderate-intensity exercise per week (walking, swimming, cycling). Even daily 30-minute walks help.
-
Eat a heart-healthy diet. Emphasise fruits, vegetables, whole grains, and lean protein. Reduce salt, saturated fats, and processed foods.
-
Limit alcohol. Heavy drinking raises blood pressure and stroke risk.
-
Get screened for atrial fibrillation. AF often has no symptoms but significantly increases clot risk. A simple ECG can detect it.
Prevention is not a one-time effort β it is an ongoing conversation with your doctor. If you want a personalised stroke risk assessment, book an appointment with our neurology team.
Frequently Asked Questions
Can a young person have a stroke?
Yes. The ICMR National Stroke Registry (2020β2022) found that nearly 14% of stroke patients in India are under 45. In younger adults, causes often include heart conditions like patent foramen ovale (a hole in the heart), blood clotting disorders, arterial dissection, and substance use. Any sudden neurological symptom warrants immediate medical attention regardless of age.
What is the difference between a stroke and a TIA?
A TIA produces the same symptoms as a stroke β face drooping, arm weakness, speech difficulty β but they resolve on their own, usually within minutes to hours. The critical difference is that a TIA does not cause permanent brain damage. However, a TIA is a medical emergency because it signals that a full stroke may follow. Approximately 10β15% of TIA patients have a full stroke within 90 days (NHS, 2025).
How long do I have to get to the hospital during a stroke?
For ischaemic stroke, the clot-dissolving drug tPA is most effective within 4.5 hours of symptom onset. Mechanical thrombectomy can be performed for up to 24 hours in some patients. But outcomes are significantly better the earlier treatment begins β every minute counts. Do not wait to βsee if it gets better.β
Can stroke be prevented?
Up to 80% of strokes are preventable (WHO, 2024). The most impactful steps are controlling blood pressure, quitting smoking, managing diabetes, staying physically active, and treating atrial fibrillation. Regular check-ups with your doctor help identify and manage risk factors before they lead to a stroke.
